Our Picks at a Glance
How To Choose The Best AC Window Unit With Heat
This is a heavy appliance you’ll live with for years, so nailing the fundamentals matters more than any single feature. You need to figure out your room size, check what kind of electrical outlet you have near the window, and understand how the heating feature actually works.
Match the BTU to Your Room Size
BTU (British Thermal Units) measures how much heat the unit can move—higher numbers mean more cooling and heating power. A room that’s too big for the unit will never get comfortable, and a unit that’s too powerful for a small room will cycle on and off constantly. For a typical bedroom around 350 square feet, an 8,000 BTU unit handles the job, while a 550-square-foot living space really wants a 12,000 BTU model. The spec sheets list the floor area each unit is designed for, and you should treat that as the ceiling of what it can handle.
Understand the Difference Between Heat Pump and Electric Heat
To stay warm in a real winter, you need to know how your AC window unit with heat makes that warmth. A heat pump (a system that reverses the cooling cycle to pull heat from the outside air) is very efficient, but it loses effectiveness when outdoor temperatures drop below freezing. Electric resistance heat strips (which work like a space heater) keep producing heat even in bitter cold. If you need heat mostly for chilly fall or spring nights, a heat pump is an efficient choice—but for genuine winter warmth, pick a unit with electric heat strips or check its minimum operating temperature. Many manufacturers state this limit plainly, like the one that stops heating below 41°F.
Check Your Outlet Voltage Before You Buy
This is the mistake that causes the most headaches. Small units, usually up to 8,000 or 12,000 BTUs, run on standard 115V household outlets and are truly plug-and-play. Larger units, especially the 18,000 and 23,000 BTU models, require a 230/208V outlet and a special NEMA 6-20 plug—the same kind your electric dryer or oven uses. If you don’t have that outlet, you’ll need an electrician, which adds cost and time to the project. Check what’s behind your window before you fall in love with a high-BTU model.

In‑Depth Reviews
1. Midea 12,000 BTU Window Air Conditioner with Heat
Our pick — 4.5★ from 200+ verified ratings; the strongest balance of quality and price.
The whisper-quiet inverter that cools a bedroom in minutes and sips electricity.
This pick earns its spot because it runs as low as 45 dBA (a decibel level quieter than a normal conversation), so it won’t disturb a nursery or a Zoom call. The inverter technology (a compressor that adjusts its speed to match cooling demand instead of switching on and off) keeps the room at a steady temperature and, according to the manufacturer, delivers up to 35% energy savings compared to the Energy Conservation Standard. Choose this unit if you want to protect your electric bill and your sleep.
It cools a 550-square-foot space with its 12,000 BTUs, but the reviews show it punches well above that—buyers report pulling a 350 sq ft bedroom down to a comfortable temperature in under 15 minutes. The heat function is genuinely useful, though there’s a catch you need to know: the heat pump will not operate if the outside temperature drops below 41°F. For fall and spring chill that’s perfect, but it’s not a winter furnace. It runs on a standard 115V outlet, which means no special wiring needed.
Beyond the raw power, this Midea is loaded with conveniences: a digital LED display, 5 modes, 3 speed settings, a 24-hour timer, and an ECO energy-saver. You can run it from your phone, your smartwatch, or your voice via Alexa and Google Assistant using the Midea SmartHome app. The washable front filter and auto shutoff keep maintenance simple, and the window fit is forgiving—it’s designed for double-hung windows with opening widths of 24 to 38.5 inches and a clear vertical opening of 14.5 inches. Installation is manageable for one person, which is rare for a 12,000 BTU unit.
Why It’s a Crowd Favorite
- Ultra-quiet 45 dBA operation suits bedrooms and nurseries
- Inverter tech saves up to 35% on energy vs. standard units
- Smart app, remote, and voice control (Alexa & Google Assistant)
- Effective dehumidifier function for muggy days
- Multiple owners mention sub-15-minute cool-down for a 350 sq ft room
The Honest Limits
- Heat pump stops working below 41°F outside
- Heavy to lift; the install is a two-person job at best
- Noticeable hum at full power, per a few owners
Grab it for: a large bedroom, nursery, or living space up to 550 sq ft where you demand quiet and low energy use.
Think twice if: you need real warmth in freezing winter—this heat pump is for mild days only.
2. ROVSUN 8,000 BTU Window Air Conditioner with Heat
A compact combo that brings app and voice smarts to the entry-level price tier.
This ROVSUN packs a lot of capability into an 8,000 BTU package, which makes it the natural choice for a smaller bedroom, office, or apartment up to 350 square feet. It pairs its cooling duties with 4,000 BTU of heating power, so you get a true year-round unit in one chassis. What makes it stand out at this level is the connectivity—you can control it from your phone or by voice via Alexa and Google Assistant, not just the included remote.
On the value side, customers note it’s a reliable performer: it cools a 34-foot bumper pull camper easily and one owner found it kept a 400 sq ft room comfortable while running on a standard 110V outlet. The install is genuinely simple, with side panels included, fitting windows 26 to 36 inches wide with a 16-inch height. The 5 modes (Heat, Auto, Cool, Dry, Fan) and 3 speeds give you plenty of flexibility, and the washable filter is easy to reach from the front panel.
The catch with this budget pick is quality control. A few reviewers point out units arriving damaged in shipping, and there’s at least one account of a unit failing after a few months of use. It’s also note some owners find the compressor a bit loud, describing a noise like water dumping. For a first-time buyer who wants the cheapest way to get app control and decent cooling, it’s a solid bet; for someone who needs absolute reliability, spending a bit more might be wise.
Smart value pick: The lowest-cost way to get a heating window AC with app and voice smarts, sized right for a typical bedroom.
The real trade-off: Occasional shipping damage and mixed reports on long-term durability—check the unit carefully on arrival.
3. Keystone 12,000 BTU Window Air Conditioner with Heat
A powerful 12,000 BTU cooler that pairs big performance with a budget-minded price.
If you want 12,000 BTUs of cooling for a 550-square-foot living room without paying premium prices, this Keystone delivers exactly that. It pairs that cooling muscle with 11,000 BTUs of supplemental heating, so it can take the edge off a cool morning without firing up the whole house furnace. The standout feature here is the I Sense remote, which reads the temperature right where you’re sitting and sends that reading back to the unit every 3 minutes for more accurate cooling.
The honest catch is that this is a budget-tier 12K, and the reviews reflect it. The most common gripes are noise—some owners found it louder than expected, even turning it off to watch TV—and a few reports of units arriving banged up or with broken panel clips. On the reliability side, some found the heat function weak, noting it needed about 75°F outside to warm a 450 sq ft room, which confirms this is supplemental heat, not a primary heat source. The 230V power requirement also means you’ll likely need an electrician to install it.
For the lower price, you still get 4-way swing (louvers that direct air in four directions), a dehumidifier, a washable filter with a reminder light, and quiet “Energy Saver” and “Sleep” modes to trim your electric bill. The remote works well, and buyers who received a good unit are very happy—one set it up for their parents, who “absolutely love this.” Just be ready for more noise than pricier models and handle any shipping damage quickly.
Strong Points
- Full 12,000 BTU cooling for up to 550 sq ft at a lower price
- I Sense remote reads room temp and adjusts every 3 minutes
- Includes dehumidifier, 4-way swing, and washable filter
- Energy Saver and Sleep modes help reduce bills
Watch Outs
- Several owners find it too loud for a TV room
- Requires a 230V outlet—not standard household plug
- Occasional shipping damage reported
Reach for this if: you want maximum cooling power per dollar for a big living area and have a 230V outlet ready.
Look elsewhere if: noise bothers you or you can’t easily add a high-voltage outlet.
4. ROVSUN 12,000 BTU Window Air Conditioner with Heat
The app-connected 12,000 BTU combo that regularly outperforms bigger portable units.
This is the bigger sibling in the ROVSUN lineup, stepping up to a full 12,000 BTUs of cooling and heating for rooms up to 550 square feet. Where it earns its keep, according to buyers, is raw performance: one owner reported it beat out both a 14,000 BTU portable and an old 10,000 BTU window unit, cooling a 350 sq ft room down to 62°F. That kind of real-world output is what makes this a value pick at its price point.
The feature set mirrors its smaller sibling—LED display, 5 modes (Heat, Auto, Cool, Dry, Fan), 3 speeds, a 24-hour timer, and an ECO energy-saver. It’s WiFi-enabled with app and Alexa/Google Assistant voice control, so you can pre-cool your place before you get home. The 208/230V requirement is the same story as other high-powered units, so check your outlet situation first.
What the reviews show is a divide between the core performance and the extras. The highest praise goes to the functionality—buyers call it “great value for money” and note the heat mode works well. The consistent friction points are installation (it’s trickier than some, requiring you to remove the chassis, install the casing, then slide the unit back in) and occasional loud operation. One buyer who ordered eight units for a project had one arrive defective, but the replacement came fast within about 2 days.
Performance-first value: 12,000 BTUs that shoppers say genuinely outperforms bigger portables, with app control included.
Sizing it up: Installation is a two-person job, and a few units arrive loud or with wrong parts packed—verify everything early.
5. Frigidaire 12,000 BTU Window Air Conditioner with Heat
A 12,000 BTU workhorse with 6-way airflow and a name you can trust for service.
This Frigidaire is built around the idea of customizable comfort. It gives you 6-way directional airflow and three different fan speeds, which means you can point cold air exactly where you want it instead of blasting the whole room. The 12,000 BTUs handle up to 550 square feet, and the supplemental heat function backs up your primary heating system when it’s not quite enough. It operates at just 54 dBA, quiet enough for a larger living space.
Owners who got a good unit love it—reviews call it “solid,” note it “gets very cold,” and praise the clean menu, filter alerts, and simple remote. The Eco Mode, Sleep Mode, and Dry Mode give you solid energy management, and the 24-hour timer plus Auto Restart (which brings the unit back to its previous settings after a power outage) add real convenience. The washable dust filter with a clean-filter alert keeps maintenance obvious and easy.
The significant catch here is the power requirement and the physical size. This unit needs a 240VAC outlet with a proprietary plug, which is a dealbreaker for anyone without that wiring. The reviews also mention it’s heavy and needs two people to install, and it’s designed for vertical windows. And there’s one nagging issue: the sleeve situation. A few buyers found it hard to find a compatible wall sleeve, so confirm your window and sleeve situation before committing.
Comfort Features
- 6-way directional airflow shapes the breeze exactly where you need it
- Quiet 54 dBA operation for living rooms
- Eco, Sleep, and Dry modes manage energy well
- Auto Restart restores settings after power loss
Installation Realities
- Needs a 240VAC outlet with a proprietary plug—not standard
- Heavy; two people required for installation
- Compatible wall sleeves can be hard to find
Ideal when: you already have a 240V outlet and want precise airflow control from a trusted brand.
Not for you if: you’re on a standard 115V household circuit or have a horizontal slider window.
6. Keystone Energy Star 12,000 BTU Inverter Window AC
Energy Star inverter tech that runs quieter and cooler without needing a 220V outlet.
Here’s the trick this Keystone pulls off that most 12,000 BTU units can’t: it delivers full 12,000 BTUs of cooling on a standard 115V household outlet. That’s a huge convenience if you don’t have a 230V circuit near your window. It uses inverter technology, which adjusts the compressor speed to match demand, and that’s why it’s Energy Star rated and operates 22% quieter on low and 5% quieter on high than regular window units.
The cooling gets high marks across the board—reviewers describe it as “really cold” and note it works well in large spaces, including a 900-square-foot area. One owner even uses it successfully in a detached garage, heating to 60°F even when it’s 30°F outside in winter, all on 110V. It dehumidifies at up to 1.73 pints per hour, and the washable filter has a clean-filter alert to remind you when it needs attention. It fits a window at least 24 inches wide and 14.5 inches tall.
The honest warning here is about the supplemental heat and long-term reliability. Like most heat pumps, this one is meant to operate between 41 and 75 degrees outside—below 41°F it struggles, and owners confirm it lacks defrost capability in colder weather. There’s also a durability concern: a small number of buyers report units failing well before they should. Treat this as a great mild-climate unit for a standard outlet, not an all-weather machine.
The 115V advantage: Full 12K cooling power that plugs into a standard outlet, with quieter inverter operation.
Respect its limits: Heat performance drops below 41°F outside, and long-term reliability has mixed reports.
7. LG 7,600 BTU Window Air Conditioner with Heat
A trusted brand and a slide-out chassis make this a favorite for medium bedrooms.
LG brings its reputation for reliability to this compact 7,600 BTU unit, which cools rooms up to 330 square feet. The headline feature is the slide in-out chassis, which makes installation vastly easier than one-piece units—you mount the outer shell in the window first, then slide the heavy inner unit into place. It runs as low as 52 dB in low mode, quiet enough for a good night’s sleep, and the 2 cooling, heating, and fan speeds give you simple control.
Buyers consistently highlight the value and the heat performance. One owner runs it in a 12’x60′ single-wide and was “surprised how good” the heat was from a 115V window unit. Another found it an exact replacement for a 22-year-old unit with zero wall modifications needed. The 24-hour timer, Auto Restart, and filter light reminder round out the convenience package.
The critical limitation shows up in cold weather. Because of newer efficiency regulations, the heat function fails below about 40°F, blowing cool air instead of warm—a change from older LG models that heated well in the cold. That’s a dealbreaker if you need winter heat, but for supplemental fall/spring warmth in a standard 115V outlet, it’s a smart, dependable choice. Assembly requires removing the outer casing, which is a two-person job due to the weight.
What Owners Love
- Slide in-out chassis simplifies a heavy install
- Quiet 52 dB low-mode operation
- Surprisingly good heat output for a 115V unit
- Perfect fit replacement for older units
Cold Weather Limits
- Heat stops working below 40°F due to efficiency regs
- Two people needed to lift and install
- No app or smart home control
Best for: bedroom-sized rooms up to 330 sq ft on a 115V outlet, where easy install and brand trust matter.
skip it if: you need genuine warmth when temps drop below 40°F—this one will just blow cool air.
8. GE 8,000 BTU Smart Window Air Conditioner with Heat Pump
A compact smart unit whose heat pump runs 2-5x more efficiently than a space heater.
This GE is the smart-home integrated pick, sized for rooms up to 350 square feet. The defining spec is the heat pump’s efficiency: it runs 2–5x more efficient than resistive heaters, which means you get meaningful warmth for less electricity. It provides supplemental heat down to 47°F outside, with an auto shut-off at 5°F to protect the unit. The 8,000 BTUs of cooling handle a standard bedroom with ease.
Integration is the big draw. You control it through the SmartHQ app on iOS or Android, or by voice with Alexa or Google Assistant, from anywhere. The 4 modes (Cool, Heat, Fan, Eco) and multiple fan speeds are managed through an electronic thermostat with a digital display. Eco Mode cycles the fan off when the room hits your set temperature, which reduces wasted operation and lowers utility costs—exactly what inverter tech is supposed to do.
The reviews split cleanly along two lines: the cooling is universally praised (“gets cold as an iceberg,” “cools the room quickly with minimal noise”), but the smart features draw sharp criticism. Multiple owners mention the Wi-Fi is unreliable—hard to connect and harder to stay connected, with one calling the smart electronics “garbage” while loving the AC itself. The install is also more involved than some, requiring drilling for the top bar and brackets. If you want a great cooling heat pump and can live with occasionally flaky Wi-Fi, this is a strong compact option.
The Efficiency Edge
- Heat pump delivers 2-5x the efficiency of resistive heaters
- SmartHQ app control plus Alexa and Google voice
- Very quiet inverter operation
- Works down to 47°F for supplemental heat
Real-World Gripes
- Wi-Fi connectivity is notoriously unreliable
- Installation needs drilling for the top bar
- Fragile exterior fins can arrive dented
Choose this if: you want a genuinely efficient heat pump in a compact 115V size and don’t mind setup quirks.
Skip the smart hype: buy this for the cooling and heat efficiency—treat the app as a bonus, not a reason to purchase.
9. PerfectAire 12,000 BTU Window AC with Electric Heater
The rare window unit with electric heat strips that actually works in deep winter.
Most window ACs with heat use heat pumps that struggle in the cold. This PerfectAire is different: it uses electric resistance heat strips rated at 3,500 BTU, which means it keeps producing warmth no matter how cold it gets outside. The reviews prove it—one owner maintained a 65°F sunroom during a 15°F record cold snap with snow on the ground. If you need real winter heating, this is the type of unit you want.
The cooling side is equally solid. It delivers 12,000 BTUs for rooms up to 550 square feet, and one buyer in a 20x20ft man cave saw temps drop from 74°F to 62°F in about 45 minutes, all while being quieter than the old unit. The full-function remote includes Follow Me portable thermostat technology, so the remote acts as a second thermostat to better control the room temperature. The front-mounted, tilt-out filter makes cleaning a breeze.
The trade-offs are the things you’d expect from a 240V unit: it requires a dedicated 240V/20A circuit, and it draws a lot of power when the heat strips are running. The capacity rating is also an interesting detail—it’s a 12,000/11,600 BTU unit, and owners advise sizing it properly to your room. It has 3 speeds in cool and fan mode but just 1 speed in heat mode, which is fine for steady warmth. For a barn, tiny home, or sunroom that needs genuine cold-weather heating, this is the pick.
Winter-proof heating: Electric heat strips keep working in sub-zero temps where heat pumps fail—proven down to 15°F.
Power hunger: Needs a dedicated 240V/20A circuit and draws heavily during heating—check your panel first.
10. LG 18,000 BTU Window Air Conditioner with Heat
Serious cooling muscle for open-plan rooms, with a heat option for the shoulder seasons.
For a big living room, basement, or multiple rooms on one floor, this LG brings 18,000 BTUs of cooling power to cover up to 1,000 square feet. Owners in uninsulated farmhouses report it holds steady temps and produces good heat and cool output. The 4-way air deflection gives you real control over where the air goes in a wide space, and the 2 cooling, heating, and fan speeds let you dial in the comfort level.
The efficiency is a genuine plus, with a SEER value of 11.2 and Auto Restart to recover from power outages. It dehumidifies at 5.7 pints and includes a washable filter, a filter light reminder, and a 24-hour on/off timer. The remote and digital control panel are straightforward, and buyers who got a good unit say it’s quieter than their old unit and works great year-round.
The honest picture here is more mixed. The unit is extremely heavy—130 pounds by one account—and needs 2 to 3 people to install it safely. A few buyers have also had serious reliability problems, with reports of defective units arriving with loud fans or compressors that don’t cool. The power requirement is a 230/208V LCDI Plug (NEMA 6-20), so a dedicated high-voltage circuit is non-negotiable. This is a powerful tool for the right space, but the weight and quality-control variance mean you should buy it ready for a potentially heavy installation.
The Big-Room Upside
- 18,000 BTUs cover up to 1,000 sq ft
- Efficient SEER 11.2 rating
- 4-way air deflection directs airflow across wide rooms
- Dehumidifies at 5.7 pints
The Heavy Reality
- Extremely heavy at 130 lbs—needs 2-3 people
- Requires a dedicated 230/208V NEMA 6-20 outlet
- Quality-control reports are mixed on reliability
Pick it for: a genuinely large space up to 1,000 sq ft where you need serious cooling and have the high-voltage outlet.
Hold off if: you can’t manage a 130-pound installation or want a plug-and-play standard outlet.
11. LG 23,000 BTU Window Air Conditioner with Heat
The biggest window unit here, throwing 23,000 BTUs across an entire large floor.
When nothing smaller will do, this LG is the biggest window-mounted option you can get, with 23,000 BTUs of cooling for rooms up to 1,400 square feet. It’s designed for living rooms, dens, and offices that need serious airflow, and it pairs that cooling with a 9,200/11,200 BTU supplemental heat function. The 2 cooling, heating, and fan speeds give you simple control, and it operates as low as 62 dB in low mode.
Owners who have a positive experience love the year-round utility—one calls it “a lifesaver especially in the winter months,” praising both the heater and AC functions. The washable filter is easy to access for cleaning, and the Auto Restart feature brings it back automatically after a power outage. On a 230V circuit, it provides serious comfort for a large home floor or a generously sized workspace.
The truth is that this is the most polarizing unit in this list. The reliability record is genuinely split: while some customers note flawless performance, others describe units that stopped cooling within 6 months or simply never blew cold air. The noise level is also contentious—some find it acceptable, others call it extremely loud. At 230V with this much power draw, it’s a major installation and a major purchase. If you truly need to cool and heat 1,400 square feet from a single window, it’s one of the only options—just go in with eyes open on the durability reports.
class-leading Coverage
- 23,000 BTUs cool up to 1,400 sq ft, the largest reach here
- Dual heat ratings of 9,200/11,200 BTU for real warmth
- Auto Restart and easy-clean washable filter
- Year-round utility praised by satisfied owners
The Gamble
- Reliability record is split—some units fail within months
- Noise level is polarizing, from acceptable to very loud
- Requires a dedicated 230V circuit
Reach for it when: you need to condition a truly huge space from one window and can handle the power demands.
Proceed with caution: the mixed reliability reports make a longer warranty a smart addition.
Understanding the Specs
BTU and Square Footage
BTU, or British Thermal Units, measures how much heat an AC can remove from a room in an hour. The rule of thumb is simple: more square footage needs more BTUs. An 8,000 BTU unit covers roughly 350 square feet, while a 12,000 BTU unit handles up to 550 square feet. Buying too smallmeans the unit runs constantly and never catches up; buying too big means it short-cycles and wastes energy. The spec sheets list the maximum floor area for a reason—treat that number as the ceiling of what the unit can handle comfortably.
Heat Pump vs. Electric Heat Strips
These two heating methods behave very differently in winter. A heat pump reverses the cooling cycle to pull warmth from outside air, which makes it very efficient—but it loses power as temperatures drop, and many stop working below 41°F. Electric heat strips work like a giant space heater inside the unit, so they keep producing warmth even in bitter cold, but they draw much more electricity. If you need heat mostly for chilly fall nights, a heat pump is the efficient choice; if you need real winter warmth, look for electric heat strips and check the unit’s minimum operating temperature.
