A window air conditioner with heat can handle summer cooling and cool-weather comfort without requiring separate appliances. My best overall pick is the GE 8,000 BTU Smart Window Air Conditioner because its inverter and heat-pump design offers a stronger balance of efficiency, temperature control, and year-round utility than basic supplemental heaters. The Keystone 8,000 BTU model is my value choice for smaller rooms, while the Soleus Air 12,000 BTU saddle unit stands out for buyers who want more heating power and a window-friendly layout. The main tradeoffs are heat-pump performance versus resistance heat, 115V convenience versus 230V output, and quiet operation versus maximum capacity. Continue reading for the full breakdown and a clear match for each room, climate, and budget.
Complete the kit
Key Takeaways
- Heat type separated the leaders: the GE and TCL heat-pump models offer more meaningful year-round utility than units with low-output supplemental resistance heaters.
- The GE 8,000 BTU model earned the top position by pairing inverter control with heat-pump operation, while larger units ranked behind it when their voltage and installation demands narrowed their appeal.
- Keystone covers both ends of the capacity range: its 8,000 BTU unit is the stronger value choice for small rooms, while its 23,200 BTU model is built for spaces up to 1,500 square feet.
- Quiet-focused shoppers have several distinct paths: ZAFRO emphasizes a 32 dB U-shaped design, Soleus uses a saddle layout, and inverter models from GE, TCL, and Midea can avoid harsh on-off cycling.
- One Midea listing requires extra caution: the 12,000 BTU U-shaped model in this lineup advertises cooling but does not identify a heating function in its supplied product name, so I would verify the exact model before buying.

ROVSUN 8000 BTU Window Air Conditioner with Heat, Smart Control, and Easy Installation
[grimfaste asin=”B0CYT1545H” mode=”image” alt=”ROVSUN 8000 BTU Window Air Conditioner with Heat, Smart Control, and Easy Installation” image=”https://m.media-amazon.com/images/I/71UNu6lyx2L._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best Smart Value
View on AmazonI chose the ROVSUN 8000 BTU as the smart-value pick because it combines app and voice control with year-round operation at a practical 115V rating. Its 350-square-foot coverage suits bedrooms, home offices, and modest living areas, while the included installation hardware lowers the setup burden. Compared with the Friedrich CEW08B11B, it offers similar 8,000 BTU cooling and 4,000 BTU heating, but its Alexa and Google Assistant support gives smart-home users more control options. The compromise is that 4,000 BTU heating is supplemental, so I would not treat it as a replacement for central heat during a cold winter. Noise output is also unspecified, making the Soleus Air a safer choice for light sleepers. This is a capable, connected option, but its window-size limits require careful measuring before purchase.
Pros:- Alexa, Google Assistant, and Wi-Fi controls support remote adjustments
- Standard 115V electrical requirement is accessible for many rooms
- Multiple operating modes and fan speeds allow flexible comfort settings
- Included side panels and instructions simplify window installation
Cons:- 4,000 BTU heat output is modest beside the 8,000 BTU cooling capacity
- Operating noise is not specified
- Fits only windows within the stated width and height limits
Best for: Smart-home users cooling a bedroom or office up to 350 square feet who want supplemental heat from a standard 115V outlet
Not ideal for: Light sleepers who need a verified noise rating or households seeking a primary winter heating system
- Cooling Capacity:8,000 BTU
- Heating Capacity:4,000 BTU
- Coverage Area:Up to 350 sq. ft.
- Electrical Rating:115V/60Hz
- Compatible Window Width:26–36 inches
- Minimum Window Height:16 inches
- Smart Controls:Wi-Fi, Alexa, and Google Assistant
Our verdict“I recommend this model for connected 115V rooms where convenient cooling matters more than strong winter heating.”
Soleus Air 12,000 BTU Window Air Conditioner with 10,000 BTU Heater, Wi-Fi Enabled, Quiet Operation, and Saddle Mount Design
[grimfaste asin=”B0CX99L3N7″ mode=”image” alt=”Soleus Air 12,000 BTU Window Air Conditioner with 10,000 BTU Heater, Wi-Fi Enabled, Quiet Operation, and Saddle Mount Design” image=”https://m.media-amazon.com/images/I/81nvDIo5zSL._AC_SX342_SY445_QL70_ML2_.jpg” link=”0″]Best Overall
View on AmazonI rank the Soleus Air 12,000 BTU model as best overall because its 10,000 BTU heater is more balanced with its cooling output than the 4,000 BTU heaters in the ROVSUN and Friedrich models. The inverter compressor and 38 dB rating also make it better suited to bedrooms, offices, and shared living spaces where efficiency and low noise carry real weight. Its saddle design preserves more of the view and supports walls up to 12.5 inches thick, a useful advantage over conventional window units. That design may still be incompatible with unusual window styles, and the 1,220-watt draw is higher than Friedrich’s listed 730 watts. App control is included, but voice-assistant compatibility is not stated. I place it above the smaller models for its stronger heat, quieter operation, and safer mounting approach.
Pros:- 10,000 BTU heater is stronger than the heating systems in the 8,000 BTU picks
- Inverter compressor supports steadier and more efficient temperature control
- 38 dB operation is well suited to bedrooms and offices
- Saddle mount preserves the view and accommodates walls up to 12.5 inches thick
Cons:- 1,220-watt rated draw may require more power than smaller alternatives
- Voice-assistant integration is not listed
- Saddle installation will not fit every window configuration
Best for: Noise-sensitive households wanting balanced heating and cooling, app control, and a view-preserving saddle installation
Not ideal for: Buyers with incompatible window styles or anyone requiring confirmed Alexa or Google Assistant control
- Cooling Capacity:12,000 BTU
- Heating Capacity:10,000 BTU
- Electrical Rating:115V
- Rated Wattage:1,220 watts
- SEER:13
- Noise Level:38 dB
- Airflow:270 CFM
- Refrigerant:R-32
- Wall Compatibility:Up to 12.5 inches thick
Our verdict“I would choose this for the strongest mix of quiet operation, substantial heat, efficient cooling, and window-friendly design.”
Friedrich CEW08B11B 8,000 BTU Heat/Cool Window Air Conditioner
[grimfaste asin=”B0F95KBBP5″ mode=”image” alt=”Friedrich CEW08B11B 8,000 BTU Heat/Cool Window Air Conditioner” image=”https://m.media-amazon.com/images/I/51EPiSdigEL._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best Brand-Name 115V Pick
View on AmazonThe Friedrich CEW08B11B earns this role for buyers who prefer a recognized climate-control brand and straightforward 115V installation. I like its fit for 300- to 350-square-foot rooms, where three cooling and heating speeds give more adjustment than a basic single-speed unit. FriedrichGo app control adds remote access, while QuietMaster technology targets lower operating sound. Compared with the ROVSUN 8000 BTU, however, Friedrich does not list Alexa or Google Assistant support, and both models provide the same 8,000 BTU cooling and 4,000 BTU heating capacities. It also lacks the Soleus Air’s inverter compressor, so temperature control may be less even and efficient. At 61 pounds and 27 inches deep, installation can require two people. I favor it for conventional reliability and room-scale comfort, not maximum heating power or advanced automation.
Pros:- Three cooling and heating speeds provide useful comfort adjustment
- FriedrichGo app supports remote operation
- QuietMaster technology is designed to reduce disruptive operating sound
- Standard 115V plug suits many residential installations
Cons:- Non-inverter compressor may cycle more abruptly than the Soleus Air system
- 4,000 BTU heating capacity is intended for modest supplemental warmth
- 61-pound weight and 27-inch depth can complicate installation
Best for: Brand-conscious apartment residents or homeowners needing app-controlled heating and cooling in a 300- to 350-square-foot room
Not ideal for: Efficiency-focused buyers seeking an inverter compressor, strong heat output, or confirmed voice-assistant support
- Cooling Capacity:8,000 BTU
- Heating Capacity:4,000 BTU
- Coverage Area:300–350 sq. ft.
- Electrical Rating:115V, 5-15P plug
- Rated Wattage:730 watts
- Speed Settings:3 cooling/heating speeds
- Compressor:Non-inverter
- Dimensions:27 x 22 x 18 inches
- Weight:61 pounds
Our verdict“I recommend the Friedrich for a medium room when brand familiarity and app control outweigh inverter efficiency and stronger heat.”
LG 18,000 BTU Window Air Conditioner with Heat, WiFi & Voice Control
[grimfaste asin=”B0D2PGFRVR” mode=”image” alt=”LG 18,000 BTU Window Air Conditioner with Heat, WiFi & Voice Control” image=”https://m.media-amazon.com/images/I/61jJxMOhuiL._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best for Large Rooms
View on AmazonI selected the LG 18,000 BTU for large rooms because its stated coverage reaches 1,000 square feet, far beyond the 350-square-foot range of the ROVSUN and Friedrich picks. That capacity makes more sense for open living areas, workshops, or combined kitchen and dining spaces. Wi-Fi plus Alexa and Google Assistant support also makes temperature changes easier when the unit is mounted across a wide room. Four-way air deflection helps distribute conditioned air, while auto restart restores operation after an outage. The tradeoff is its 230V power requirement: many bedrooms and apartments lack a matching outlet, and electrical work can add substantial cost. The supplied data also omits heating capacity, wattage, and noise output, making its winter performance and bedroom suitability harder to judge than the Soleus Air. I would buy it for scale, not specification transparency.
Pros:- 18,000 BTU cooling capacity serves much larger rooms than the 8,000 BTU models
- Alexa, Google Assistant, Wi-Fi, and remote controls provide several operating options
- Four-way air deflection helps move air through broad spaces
- Auto restart and a 24-hour timer support scheduled, unattended operation
Cons:- Requires a 230V electrical connection that many rooms do not have
- Heating capacity and rated power consumption are not provided
- Noise level is not specified
Best for: Owners of large open rooms up to 1,000 square feet who already have a compatible 230V outlet and want voice control
Not ideal for: Renters, small-room users, or shoppers who need published heating-output, wattage, and noise figures before buying
- Cooling Capacity:18,000 BTU
- Coverage Area:Up to 1,000 sq. ft.
- Electrical Rating:230V
- System Type:Window air conditioner with heat
- Smart Controls:Wi-Fi, Alexa, and Google Assistant
- Remote Control:Included
- Timer:24-hour programmable
- Air Direction:4-way air deflection
- Power Recovery:Auto restart
Our verdict“I would pick this LG for a large 230V-ready room where broad coverage and smart control take priority over published heat and noise data.”
Keystone 23,200 BTU Window Air Conditioner with 16,000 BTU Supplemental Heat and Dehumidifier, 230V, for Large Rooms up to 1,500 Sq.Ft.
[grimfaste asin=”B0CHZ5M5JB” mode=”image” alt=”Keystone 23,200 BTU Window Air Conditioner with 16,000 BTU Supplemental Heat and Dehumidifier, 230V, for Large Rooms up to 1,500 Sq.Ft.” image=”https://m.media-amazon.com/images/I/61ew6IVa08L._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best for Extra-Large Spaces
View on AmazonThe Keystone 23,200 BTU sits at the top of the capacity ladder, so I reserve it for extra-large living areas, studios, and workspaces up to 1,500 square feet. It cools 500 more square feet than the LG 18,000 BTU model and adds 16,000 BTU supplemental heat, dehumidification, and fan circulation. Its smart remote senses temperature near the user rather than only at the window, which can reduce hot and cold pockets across a broad room. Power is the main barrier: this unit requires 230V service, and its size calls for a window opening at least 19.5 inches high. The heater is explicitly supplemental, so I would not rely on it as the sole heat source in severe weather. Compared with the LG, smartphone and voice controls are absent. I rank it for raw reach and versatility rather than convenience or easy placement.
Pros:- 23,200 BTU cooling capacity covers the largest stated area in this group
- 16,000 BTU supplemental heater adds substantial shoulder-season warmth
- Smart remote senses temperature closer to the occupant
- Dehumidifier, fan circulation, and energy-saving modes broaden year-round usefulness
Cons:- Supplemental heater is not designed to replace a primary heating system
- Requires 230V service and a window at least 19.5 inches high
- No Wi-Fi or voice control is listed
Best for: Homeowners cooling extra-large rooms up to 1,500 square feet who have 230V service and need dehumidification plus supplemental heat
Not ideal for: Apartment renters, small-window households, or cold-climate buyers seeking a primary heater and app-based controls
- Cooling Capacity:23,200 BTU
- Heating Capacity:16,000 BTU supplemental heat
- Coverage Area:Up to 1,500 sq. ft.
- Electrical Rating:230V
- Minimum Window Height:19.5 inches
- Moisture Control:Dehumidifier mode
- Air Circulation:Fan mode
- Temperature Control:Smart remote with temperature sensing
- Installation Hardware:Window installation kit included
Our verdict“I recommend this Keystone when maximum room coverage and moisture control matter more than smart-home features or simple installation.”
Keystone 8,000 BTU Window Air Conditioner with 3,500 BTU Supplemental Heating, 115V
[grimfaste asin=”B0CHZ17CDB” mode=”image” alt=”Keystone 8,000 BTU Window Air Conditioner with 3,500 BTU Supplemental Heating, 115V” image=”https://m.media-amazon.com/images/I/61EFvD+3FJL._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best Basic Supplemental-Heat Pick
View on AmazonI rank the Keystone 8,000 BTU as the straightforward choice for cooling a bedroom or office while adding occasional warmth between seasons. Its remote temperature sensing can regulate conditions around the occupant rather than near the window, where readings may be misleading. Compared with the GE 8,000 BTU model, Keystone offers similar 350-square-foot cooling coverage but uses 3,500 BTU supplemental heat rather than positioning its heating system as a heat pump. That makes it better suited to chilly mornings than sustained winter heating. It also lacks the app and voice controls found on the Garvee unit. I place it behind those smarter options for convenience, but its 115V power requirement, energy-saving modes, and included installation kit make it an approachable choice for buyers who value simple seasonal climate control.
Pros:- Remote sensor measures temperature closer to the user
- Runs from a standard 115V electrical supply
- Cooling, supplemental heating, dehumidification, and fan functions
- Energy-saving modes can reduce unnecessary compressor operation
Cons:- 3,500 BTU heating output is not designed to replace a primary heat source
- No app or voice-control capability listed
- Performance in heating mode depends on outdoor conditions
Best for: Bedroom or home-office users who need dependable 115V cooling plus light supplemental warmth during mild weather
Not ideal for: Buyers seeking a primary winter heater or climate control for a room larger than 350 square feet
- Cooling Capacity:8,000 BTU
- Heating Capacity:3,500 BTU
- Recommended Room Size:Up to 350 sq. ft.
- Voltage:115V
- Climate Functions:Cooling, supplemental heating, dehumidification, and fan
- Temperature Control:Remote with room-temperature sensing
- Efficiency Features:Energy-saving modes
- Installation Kit:Included
Our verdict“This Keystone makes sense for a small-room buyer who wants simple cooling and occasional warmth without paying for an elaborate smart system.”
Garvee 8000 BTU Window Air Conditioner with Heat, Dehumidifier & Fan
[grimfaste asin=”B0GWC3SBZV” mode=”image” alt=”Garvee 8000 BTU Window Air Conditioner with Heat, Dehumidifier & Fan” image=”https://m.media-amazon.com/images/I/81vd5vkqm3L._AC_SX342_SY445_QL70_ML2_.jpg” link=”0″]Best Control Flexibility
View on AmazonThe Garvee 8000 BTU earns its place through control choices: I can recommend it to buyers who want access from an app, remote, touch panel, or voice assistant. That is a meaningful convenience advantage over the basic Keystone 8,000 BTU, while its four-in-one operation covers cooling, heating, moisture removal, and air circulation in rooms up to 350 square feet. Its stated 52 dB noise level is respectable, although the 32 dB ZAFRO is the stronger bedroom pick for sound-sensitive sleepers. Installation is the main dividing line. At 81.4 pounds, Garvee calls for more lifting help than its small-room capacity might suggest, and it needs a window at least 26 inches wide and 16 inches high. I rank it for connected convenience, not portability or unusually broad window compatibility.
Pros:- App, remote, touch, and voice controls suit different routines
- Four operating functions reduce the need for separate seasonal appliances
- 52 dB rating is suitable for many living spaces
- 115V operation avoids a dedicated 230V outlet
Cons:- 81.4-pound weight makes installation a two-person job for many buyers
- Requires a window between 26 and 36 inches wide with at least 16 inches of opening height
- Cooling coverage stops at 350 square feet
Best for: Smart-home users cooling and heating a 350-square-foot room who want several ways to adjust settings
Not ideal for: Solo installers, renters with narrow windows, or sound-sensitive sleepers who would benefit from the quieter ZAFRO
- Cooling Capacity:8,000 BTU
- Recommended Room Size:Up to 350 sq. ft.
- Noise Level:52 dB
- Voltage:115V
- Wattage:730W
- Dimensions:19.76 x 24.02 x 15.16 inches
- Weight:81.4 lb.
- Window Compatibility:26 to 36 inches wide; minimum 16-inch opening height
- Control Methods:App, remote, touch, and voice
Our verdict“Choose the Garvee when smart-control versatility matters more than low weight or whisper-quiet operation.”
ZAFRO U-Shaped Inverter Window Air Conditioner with Heat, 12000BTU, Ultra Quiet (32dB), Smart Control
[grimfaste asin=”B0GX1F843F” mode=”image” alt=”ZAFRO U-Shaped Inverter Window Air Conditioner with Heat, 12000BTU, Ultra Quiet (32dB), Smart Control” image=”https://m.media-amazon.com/images/I/71L70qQNSbL._AC_SX300_SY300_QL70_FMwebp_.jpg” link=”0″]Best for Quiet Bedrooms
View on AmazonI put the ZAFRO U-Shaped Inverter first for noise-sensitive bedrooms because its layout keeps the compressor outside and carries a stated 32 dB indoor noise rating. That is far quieter on paper than the 52 dB Garvee and 62 dB LG 23,000 BTU. ZAFRO also brings more heating muscle than the smaller Keystone, pairing 12,000 BTU ASHRAE cooling with 8,000 BTU heat and inverter regulation for steadier output. Its U-shaped format preserves more separation between the compressor and room, but installation may be less intuitive than fitting a conventional box unit. Buyers also need a 24- to 48-inch-wide window with at least 16 inches of opening. I rank it above the 8,000 BTU models for larger sleeping spaces, though its higher expected price and more involved setup weaken its appeal for basic guest-room duty.
Pros:- 32 dB rating is the quietest stated figure in this five-product group
- U-shaped construction places the compressor outside the room
- 8,000 BTU heating capacity exceeds the smaller Keystone’s supplemental output
- App, voice, remote, and touch controls offer broad flexibility
Cons:- U-shaped installation may be more involved than installing a conventional unit
- Requires a compatible 24- to 48-inch-wide window
- Likely costs more than traditional 8,000 BTU models
Best for: Light sleepers and smart-home users who need heating and cooling for a medium-to-large bedroom
Not ideal for: Budget-focused buyers or anyone whose window is narrower than 24 inches or opens less than 16 inches
- Cooling Capacity:12,000 BTU ASHRAE; 8,100 BTU DOE
- Heating Capacity:8,000 BTU
- Noise Level:32 dB
- Estimated Annual Energy Cost:$61
- Window Compatibility:24 to 48 inches wide; minimum 16-inch opening
- Operating Modes:Cool, dehumidify, heat, fan, Eco, Sleep, and Mute
- Moisture Removal:Up to 70 pints per day
- Control Methods:App, voice, remote, and touch panel
- Convenience Features:Child lock, window lock, 24-hour timer, and washable filter
Our verdict“The ZAFRO is my quiet-room pick for buyers willing to accept a more involved installation in exchange for low noise and stronger output.”
GE 8,000 BTU Smart Window Air Conditioner with Heat Pump and Inverter
[grimfaste asin=”B0GRVXBNP4″ mode=”image” alt=”GE 8,000 BTU Smart Window Air Conditioner with Heat Pump and Inverter” image=”https://m.media-amazon.com/images/I/81Qg5CnFqjL._AC_SY300_SX300_QL70_FMwebp_.jpg” link=”0″]Best for Mild-Climate Heating
View on AmazonThe GE 8,000 BTU Smart model is my mild-climate pick because it combines an inverter compressor and heat pump in a compact unit sized for 350-square-foot rooms. Compared with the Keystone 8,000 BTU, GE offers Wi-Fi and voice control plus a heating system intended to operate down to 47°F, making it the more capable choice for routine cool-weather use. Keystone remains appealing when occasional supplemental warmth and simpler controls are enough. GE also fits a shorter opening than the Garvee, needing at least 14 inches of height rather than 16. The limitation is climate: this is not the unit I would choose for dependable heat through a freezing winter, and its stated operating data includes an auto shut-off at 5°F. I rank it for efficient shoulder-season comfort, while ZAFRO remains better for larger rooms and lower stated noise.
Pros:- Heat-pump system is better suited to regular mild-weather heating than basic supplemental heat
- Inverter operation can reduce cycling and energy use
- Wi-Fi, Alexa, and Google Assistant support enable remote adjustments
- Compact height fits windows that cannot accommodate the Garvee or ZAFRO
Cons:- Heating is specified only down to 47°F for normal operation
- Limited to rooms around 350 square feet
- Window installation may still require assistance despite the compact dimensions
Best for: Apartment dwellers in mild climates who want efficient heating and cooling for a bedroom, office, or compact living room
Not ideal for: Households relying on a window unit as their only heat source during sustained freezing weather
- Cooling Capacity:8,000 BTU
- Recommended Room Size:Up to 350 sq. ft.
- Heating System:Heat pump
- Heating Temperature Range:Down to 47°F
- Low-Temperature Shut-Off:5°F
- Compressor Type:Inverter
- Dimensions:18.19 x 18.98 x 13.31 inches
- Window Compatibility:24.5 to 36 inches wide; minimum 14-inch opening height
- Smart Compatibility:Wi-Fi, Alexa, and Google Assistant
Our verdict“Pick the GE for connected, energy-conscious heating and cooling in a small room where winter temperatures are generally mild.”
LG 23,000 BTU 230V Window-Mounted Air Conditioner with Heat and Remote Control
[grimfaste asin=”B0C6NJKXXL” mode=”image” alt=”LG 23,000 BTU 230V Window-Mounted Air Conditioner with Heat and Remote Control” image=”https://m.media-amazon.com/images/I/61cCxUJWy4L._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best for Extra-Large Rooms
View on AmazonThe LG 23,000 BTU 230V is the specialist for open living areas where every 8,000 or 12,000 BTU model here would be undersized. Its listed coverage reaches 1,400 square feet, and its 9,200 BTU heating capacity provides more warmth than ZAFRO or Keystone. I would still treat that heat as supplemental, especially when outdoor temperatures fall sharply. Large-room power brings clear penalties: this unit needs a 230V electrical supply, is likely to consume more energy, and will be harder to lift into place than the already-heavy Garvee. At 62 dB, it is also much less bedroom-friendly than the 32 dB ZAFRO. Multiple fan speeds, remote operation, and auto restart make daily use manageable, but there is no listed app control. I rank LG for reach and output alone, not quietness, installation ease, or connected features.
Pros:- Listed coverage far exceeds the small- and medium-room models
- 9,200 BTU heating output is the strongest among these five products
- Auto restart restores operation after a power outage
- Remote control and multiple fan speeds simplify room-wide adjustments
Cons:- Requires a 230V electrical connection
- Large, high-output construction can make installation difficult and increase energy demand
- 62 dB rating is much louder than the ZAFRO’s stated 32 dB
Best for: Homeowners with a compatible 230V outlet who need one window unit for a large open-plan room up to 1,400 square feet
Not ideal for: Renters with standard 115V outlets, upstairs solo installers, or sleepers who need very low operating noise
- Rated BTU:23,000 BTU
- Listed Cooling Capacity:11,200 BTU
- Heating Capacity:9,200 BTU
- Coverage Area:Up to 1,400 sq. ft.
- Voltage:230V
- Noise Level:62 dB
- Control:Remote control
- Recovery Feature:Auto restart after power outages
Our verdict“Choose this LG only when large-room capacity outweighs the added electrical, installation, noise, and operating demands.”
LG Window Air Conditioner with Heat LW1223HR White (Renewed)
[grimfaste asin=”B0FC7WW73F” mode=”image” alt=”LG Window Air Conditioner with Heat LW1223HR White (Renewed)” image=”https://m.media-amazon.com/images/I/71ZhT5YAoOL._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best Refurbished Heat-and-Cool Value
View on AmazonI rank the LG LW1223HR as the value-focused choice for buyers who can accommodate its electrical demands. Its 12,200 BTU cooling and 11,200 BTU heating are more evenly matched than the Whirlpool model’s 8,000/4,000 BTU pairing, making the LG more useful across changing seasons in a large room. Coverage reaches 570 square feet, while fan and dehumidifying modes add flexibility beyond temperature control. The catch is substantial: this renewed unit requires a dedicated 230V circuit, so wiring and installation can erase part of the initial savings. Refurbished condition also carries more longevity uncertainty than buying the TCL or either Midea new. I would choose it for strong heating capacity at a lower likely entry price, but only after confirming the outlet, window support, and warranty details.
Pros:- Heating capacity is close to its cooling output, supporting more credible multi-season use
- Covers rooms up to 570 square feet
- Cooling, heating, fan, and dehumidifying modes handle varied room conditions
- R32 refrigerant has a lower environmental impact than older refrigerant types
Cons:- Dedicated 230V circuit may require professional electrical work
- Large-unit installation is more demanding than installing an 8,000 BTU model
- Renewed condition introduces added uncertainty around wear and service life
Best for: Budget-minded owners of 400- to 570-square-foot rooms who already have a suitable 230V circuit and want substantial heating as well as cooling
Not ideal for: Renters, buyers limited to standard 115V outlets, or anyone unwilling to accept the longevity uncertainty of a renewed appliance
- Cooling Capacity:12,200 BTU
- Heating Capacity:11,200 BTU
- Coverage Area:Up to 570 sq ft
- Voltage:230V
- Refrigerant:R32
- Display:LED
- Remote Included:Yes
- Condition:Renewed
Our verdict“I recommend this LG to value seekers who already have 230V power and prioritize robust heating over smart controls and new-condition assurance.”
Midea 12,000 BTU U-Shaped Smart Inverter Window Air Conditioner

View on AmazonThe Midea U-Shaped Smart Inverter earns a narrow role here: it is the best option for buyers who prioritize quiet cooling but already have another heat source. At 32 dBA, it is quieter on paper than the 45 dBA Midea heat model, and its U-shaped cabinet lets the window open after installation. Claimed energy savings above 37%, app access, and voice control make daily cooling easy to automate. Yet the supplied product data lists cooling only, with no heat function, so it does not fully satisfy the roundup’s central promise. Its window requirements are also precise, and advanced design raises the likely purchase price. I would place it behind true heat-and-cool models such as the TCL Q-Series unless silence, window usability, and efficient summer operation matter more than seasonal versatility.
Pros:- 32 dBA rating is the quietest stated noise level in this five-product batch
- U-shaped cabinet permits the window to open after installation
- Smart inverter design claims more than 37% energy savings

[grimfaste asin=”B0DFRQMM67″ mode=”image” alt=”TCL 12000 BTU Q-Series Smart Inverter Window AC with Heat Pump” image=”https://m.media-amazon.com/images/I/71HW91nFmjL._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best Overall
View on AmazonI put the TCL 12,000 BTU Q-Series first because it combines true heat-pump operation, large-room cooling, inverter efficiency, and smart controls without demanding a 230V circuit. Its standard 115V requirement makes it easier to place than the LG LW1223HR, while app, voice, and remote access offer more control flexibility than the smaller Whirlpool. The claimed energy savings of up to 67% are compelling, although real savings will vary with climate, settings, and usage. Installation is the main constraint: the unit needs a 29.5- to 41-inch-wide window and an 18.5-inch opening, which rules out many compact windows. The supplied data also lacks a separate heating-capacity figure and low-temperature operating limit. I rank it highest for its balance, but cold-climate buyers should verify winter performance before relying on it as primary heat.
Pros:- Provides heat-pump heating and 12,000 BTU cooling in one unit
- Runs from a standard 115V electrical supply
- Inverter technology supports quiet operation and claimed savings up to 67%
- App, voice, and remote controls provide several ways to adjust settings
Cons:- Wide cabinet and 18.5-inch opening requirement limit window compatibility
- Separate heating output is not stated in the supplied specifications
- Low-temperature heat-pump operating range is not provided
Best for: Owners of large bedrooms, living rooms, or studios who want smart heating and cooling from a standard 115V outlet
Not ideal for: Homes with narrow or shallow window openings, or cold-climate buyers seeking a documented primary-heating replacement
- Cooling Capacity:12,000 BTU
- Heating Type:Heat pump
- Coverage Area:Up to 550 sq ft
- Voltage:115V
- Control Options:App, voice, and remote

- Compatible Window Width:29.5 to 41 inches
- Required Window Height:18.5 inches
Our verdict“I recommend the TCL as the strongest all-around choice for buyers who want efficient heat and cooling without installing a 230V circuit.”
Whirlpool 8,000 BTU Window Air Conditioner with Supplemental Heat
[grimfaste asin=”B0DMTQK4VB” mode=”image” alt=”Whirlpool 8,000 BTU Window Air Conditioner with Supplemental Heat” image=”https://m.media-amazon.com/images/I/51ytTVGCdpL._AC_SX342_SY445_QL70_FMwebp_.jpg” link=”0″]Best for Small Rooms
View on AmazonThe Whirlpool 8,000 BTU model is my small-room pick because its output and feature set fit bedrooms, offices, and dens better than the larger 12,000 BTU units. Cooling coverage reaches 350 square feet, and the included mounting kit reduces installation friction compared with the wider TCL Q-Series. Its 4,000 BTU supplemental heater, however, delivers only half the cooling output and is meant for taking the chill off rather than handling a harsh winter. Eco and sleep modes, remote operation, and a washable filter make routine use straightforward, while dehumidification helps during muggy weather. The missing energy-efficiency rating makes operating-cost comparisons difficult, and this model lacks the app and voice controls offered by TCL and Midea. I favor it for modest spaces where simplicity matters, not for buyers seeking primary heat or whole-room smart automation.
Pros:- Output is appropriately sized for rooms up to 350 square feet
- Included window-mounting kit supports a simpler installation
- Eco and sleep modes suit overnight and everyday use
- Washable filter avoids recurring disposable-filter purchases
Cons:- 4,000 BTU supplemental heat is inadequate as primary winter heating
- No energy-efficiency rating is provided for cost comparisons
- Lacks Wi-Fi, app, and voice control
Best for: Bedroom, home-office, or den owners with spaces up to 350 square feet who need cooling plus occasional mild-weather heat
Not ideal for: Cold-climate households or rooms above 350 square feet, because the 4,000 BTU heater is supplemental and coverage is limited
- Cooling Capacity:8,000 BTU
- Supplemental Heat:4,000 BTU
- Room Size:Up to 350 sq ft
- Dehumidification Rate:Up to 1 pint per hour
- Control Type:Digital controls with remote
- Operating Modes:Includes eco and sleep modes
- Filter:Washable
- Installation Hardware:Window-mounting kit included
Our verdict“I recommend the Whirlpool for smaller rooms that need dependable cooling and occasional warmth without paying for elaborate smart features.”
Midea 12,000 BTU Window Air Conditioner with Heat, Smart Inverter, Energy Star
[grimfaste asin=”B0GL6H2J7P” mode=”image” alt=”Midea 12,000 BTU Window Air Conditioner with Heat, Smart Inverter, Energy Star” image=”https://m.media-amazon.com/images/I/718xStCA+5L._AC_SY300_SX300_QL70_FMwebp_.jpg” link=”0″]Best Smart Bedroom Pick
View on AmazonI chose the Midea 12,000 BTU heat-and-cool model for buyers who want connected controls and restrained noise in a bedroom or living area. Its 45 dBA rating is louder than the cooling-only Midea U at 32 dBA, but this version adds supplemental heat, dehumidification, and Energy Star-rated inverter operation. That broader feature mix makes it a better match for the title and more flexible across mild seasons. App, voice, remote, and LED controls also give it more ways to operate than the Whirlpool. The firm limitation is temperature: its heat pump stops below 41°F outdoors, so another heating system remains necessary in colder regions. It also requires a 24- to 38.5-inch-wide window with a 14.5-inch sash opening. I rank it behind the TCL because the cutoff narrows its winter usefulness, but it remains a polished smart-room option.
Pros:- Combines 12,000 BTU cooling, supplemental heating, and dehumidification
- 45 dBA operation is suitable for many bedrooms and living spaces
- Energy Star inverter design claims energy savings up to 35%
- Supports LED, remote, app, and voice control
Cons:- Heat pump does not operate when outdoor temperature falls below 41°F
- Supplemental heat cannot replace a cold-climate primary heating system
- Installation requires a window within specific width and sash-opening limits
Best for: Smart-home users in mild climates who want quiet cooling, dehumidification, and shoulder-season heat for rooms up to 550 square feet
Not ideal for: Buyers expecting dependable heat below 41°F outdoors or those with windows narrower than 24 inches
- Cooling Capacity:12,000 BTU
- Room Size:Up to 550 sq ft
- Energy Certification:Energy Star
- Noise Level:45 dBA
- Control Options:Digital LED, remote, app, and voice
- Heating Temperature Limit:Heat pump does not operate below 41°F outdoors
- Window Compatibility:24 to 38.5 inches wide with 14.5-inch sash opening
- Dimensions:19.41 x 22.17 x 13.9 inches
Our verdict“I recommend this Midea for connected homes in mild climates where quiet cooling matters more than dependable freezing-weather heat.”
How We Picked
I ranked these units around their ability to serve as a credible cooling-and-heating appliance, not simply as an air conditioner with a minor heater added. My highest weights went to heating technology and usable output, cooling capacity, inverter operation, voltage requirements, and the room sizes each model can realistically serve. Heat-pump models received an advantage for efficiency and moderate-weather heating, while resistance-based models gained ground only when their heater output, price, or simplicity made sense for a defined buyer.
I also compared noise control, installation demands, smart features, maintenance access, and value. U-shaped and saddle designs ranked well when they reduced noise or preserved more of the window, but their shape did not outweigh weak heating information or uncertain fit. Large 230V units scored highly for raw capacity yet ranked below more versatile 115V choices because they require a compatible outlet and heavier installation. This approach puts the GE 8,000 BTU heat-pump model first for broad appeal, followed by more specialized choices for premium comfort, large rooms, low prices, and easier setup.
Factors to Consider When Choosing Window Air Conditioner And Heat
I would choose a window air conditioner with heat by working backward from the room, local winter temperatures, electrical supply, and expected heating role. The label alone does not reveal whether a unit can replace a heater or merely take the chill out of a room. These five factors expose the differences that matter after installation.
Heat Pump or Supplemental Resistance Heat
Heat pumps move heat rather than creating it through electric resistance, which can reduce electricity use during mild weather. They also tend to regulate temperature more smoothly when paired with an inverter compressor. A unit labeled supplemental heat may use a smaller resistance element intended for cool evenings rather than sustained winter duty. Buyers often mistake the cooling BTU figure for the heating output, even though the two ratings can differ sharply. I would check the separate heating capacity and the lowest operating temperature stated by the manufacturer. In freezing climates, I would keep a primary heating system available unless the unit is specifically rated for low outdoor temperatures.
Match Capacity to the Room and Its Heat Load
Cooling capacity should match the actual room, including ceiling height, sun exposure, insulation, and connected spaces. An oversized fixed-speed unit may cool quickly but shut off before removing enough humidity, while an undersized model can run constantly. Inverter units tolerate mild oversizing better because they can reduce compressor speed, yet a huge capacity mismatch still wastes money and window space. Heating demand can exceed cooling demand in poorly insulated rooms, so square-foot claims are only a starting point. I would move up a capacity class for strong afternoon sun or open-plan layouts, but I would not buy a 23,000 BTU model for a closed bedroom. Air sealing around the cabinet can matter nearly as much as the advertised output during winter.
Check Voltage Before Comparing Prices
Most smaller units use a standard 115V outlet, making them easier to install in bedrooms, offices, and rentals. High-capacity models often need 230V power, a dedicated circuit, and a different receptacle. That electrical work can erase the apparent value of a larger unit if the room is not already wired for it. I would verify the plug configuration, amperage, and circuit rating before ordering because an adapter does not make an incompatible circuit safe. A 230V model makes sense when large-room output outweighs installation cost. Renters and buyers seeking a simple seasonal appliance will usually be better served by a properly sized 115V unit.
Choose a Cabinet Style That Fits the Window
Traditional window units are widely compatible, but they block more of the view and carry vibration directly into the sash. U-shaped models place the window between the indoor and outdoor sections, which can reduce perceived noise and leave the sash closer to its normal position. Saddle designs sit lower across the sill and may preserve sightlines, though their depth and weight can complicate installation. I would measure the opening width, sill depth, sash clearance, and exterior obstructions rather than relying on room size alone. Buyers in upper-floor rooms should also check local rules for brackets and exterior support. The best cabinet is the one that provides secure support and a tight winter seal, not simply the quietest laboratory rating.
Pay More for Control, Not Feature Count
Inverter control is usually worth paying for when the unit will run daily because it can reduce cycling, noise swings, and temperature fluctuations. Wi-Fi and voice control are helpful for schedules, remote adjustments, or preheating a room, but they do not improve weak heating hardware. A basic remote may be enough for a guest room or occasional use, making an app-enabled premium unnecessary. I place greater value on accessible filters, clear mode controls, dehumidification, and reliable thermostat behavior than on a long list of app functions. Buyers should also check whether heating schedules work independently from cooling schedules. My preferred upgrade path is better compressor technology first, stronger heating performance next, and connected features after those fundamentals.
Frequently Asked Questions
Can a Window Air Conditioner With Heat Replace My Main Heater?
In a mild climate, a properly sized heat-pump window unit may handle much of a room’s winter heating. A low-output resistance heater is better treated as backup comfort during cool weather. Outdoor temperature limits matter because some heat pumps lose capacity or stop heating when conditions become too cold. I would compare the stated heating BTU output with the room’s heat loss rather than using the cooling rating. For freezing winters, I would retain a separate primary or backup heat source.
Is a Heat-Pump Window Unit Better Than One With Supplemental Heat?
A heat-pump model is usually the better daily heater because it can deliver more heat per unit of electricity in suitable weather. Supplemental resistance heat has fewer climate-dependent performance changes, but it often costs more to operate and may have modest output. The heat-pump advantage becomes smaller as outdoor temperatures fall, especially if the model lacks a low-temperature rating. Resistance heat can still make sense for short periods in a small room or for buyers prioritizing a lower purchase price. I would choose based on how often heating will run, not simply which product costs less upfront.
Do I Need a 230V Outlet for a Window AC With Heat?
No, several 8,000 and 12,000 BTU models use 115V power, which suits many bedrooms and home offices. Large-capacity units such as the 18,000 to 23,200 BTU options commonly require 230V service. The outlet shape alone is not enough; the circuit amperage and manufacturer requirements must also match. I would never use an extension cord or informal adapter to bypass those requirements. If the room lacks the proper circuit, a smaller 115V inverter model may cost less overall than adding electrical work.
Are U-Shaped and Saddle Units Actually Quieter?
U-shaped and saddle cabinets can reduce indoor noise by placing more compressor hardware outside and using the closed window as a partial barrier. Their advantage is most noticeable in bedrooms, offices, and rooms where a conventional cabinet transfers vibration into the sash. Installation quality still matters because a loose bracket or poorly supported sill can create rattles. Published decibel figures may also use different fan speeds or measurement distances, so they are not always directly comparable. I would treat cabinet design as a strong clue, then pair it with inverter operation and solid mounting for the best chance of quiet performance.
How Can I Tell Whether an Online Listing Really Includes Heat?
Start with the exact model number and mode list, since product families often contain visually similar cooling-only and heat-enabled versions. The specifications should show a separate heating capacity, heating wattage, or heat-pump mode rather than relying on a vague seasonal description. I would cross-check the manufacturer manual and energy label before purchase. This matters for the Midea U-shaped entry here because its supplied name lists cooling features but does not identify heat. If a retailer cannot confirm the function in writing, I would choose a clearly documented heat model instead.
Conclusion
For most buyers, I recommend the GE 8,000 BTU Smart Heat Pump and Inverter model as Best Overall because it combines efficient temperature control, connected operation, and a genuine heating-focused design. The Keystone 8,000 BTU unit is my Best Value for a smaller room where supplemental heat is enough, while the ROVSUN 8,000 BTU model is the best fit for beginners who prioritize straightforward controls and easier installation. Buyers seeking a premium combination of stronger heating output, quiet operation, and a window-preserving layout should choose the Soleus Air 12,000 BTU saddle model. For specific needs, I would pick the ZAFRO 12,000 BTU U-shaped unit for low-noise rooms, the TCL Q-Series for another smart heat-pump option, and the Keystone 23,200 BTU model for a large space with compatible 230V power. The Midea cooling-only listing should be skipped unless the seller verifies an exact heat-enabled model.
