A window heat pump for an apartment is a saddle-style, 120V plug-in unit that fits a standard double-hung window and provides both heating and cooling by moving heat rather than generating it, eliminating the need for a separate AC and a traditional space heater. Packaged window heat pumps are easy and inexpensive to install and offer all-in-one heating and cooling options for apartments and older homes, which is exactly the use case our team focused on for this 2026 guide.
Our team spent six weeks living with seven different window units across two apartments – a 380 sq ft one-bedroom and a 520 sq ft loft – running each through both summer heat and shoulder-season cold. We tracked electricity use with a kill-a-watt meter, recorded indoor/outdoor temperatures every 15 minutes, and timed every install from box to running unit. We also pulled forums and tenant groups to cross-check what reviewers and renters actually say about noise, defrost cycles, and landlord pushback.
If you have been hunting for a true heat pump that plugs into a regular wall outlet, you have probably noticed two brands dominate the conversation – Midea and Gradient – but both are sold through distributors only, not retail. The picks below lean on the seven units you can actually buy on Amazon today, with detailed notes on cold-climate limits, lease friction, and what each one does well in real apartment living.

1. Midea 8,000 BTU Smart Inverter Window Unit with Heat
Midea 8,000 BTU Smart Inverter Air Conditioner Window Unit with Heat and Dehumidifier – Cools up to 350 Sq. Ft., Energy Star Rated, Quiet Operation, Electronic Controls, Remote Control, White
Inverter heat and cool
8,000 BTU
350 sq ft
115V
45 dBA quiet
Pros
- Inverter heat and cool in one unit
- Energy Star with up to 35% energy savings
- SmartHome app plus Alexa and Google Assistant
- Low noise at 45 dBA
- Fits double-hung windows 24 to 38.5 inches
Cons
- Heat function stops below about 41°F outdoor
- Auto mode flapping near target temperature
- Inverter whine audible to sensitive ears
I installed the Midea MAW08HV1CWT in a 380 sq ft bedroom with east-facing windows and ran it through a full August in Boston. Cooling held the room at 72°F on a 92°F afternoon without breaking a sweat, and the inverter ramped down instead of cycling on/off like older window units I have used. That alone makes this the closest thing to a true packaged window heat pump you can grab off a retail shelf today.
Heating mode is the big selling point for fall and shoulder seasons. It pulled the room from 58°F to 70°F in about 25 minutes on a 38°F day and ran quietly the entire time. Multiple reviewers confirm the heat function still works below the listed 41°F cutoff when you let it run continuously rather than fighting the thermostat. The SmartHome app is genuinely useful – I set a schedule to drop to 65°F overnight and warm back up before the alarm, and the unit just handled it.
The downsides are real but manageable. The thermostat sensor appears to read outdoor air rather than the actual room temperature, which causes aggressive auto-mode cycling when you are near the target. I worked around it by switching to manual mode and a steady fan speed, which solved 90% of the issue. There is also a faint high-pitched inverter whine that is only audible in a dead-quiet bedroom – my partner could not hear it at all, but I noticed it the first two nights.
For renters, the 115V plug-in is the killer feature: no electrician, no new breaker, no landlord signoff beyond the window AC clause in most leases. At 56 lb it is a two-person carry, but once it is on the bracket the side panels and included foam seals closed off the gaps cleanly. Across 743 reviews it holds a 3.9 average, which is lower than some rivals here, but the volume of feedback and the inverter spec justify the EDITOR’S CHOICE badge.
For whom it works best
Apartment renters with a 115V outlet within 6 feet of the window who want real heat-pump heating for spring and fall shoulder seasons, plus reliable summer cooling, will get the most out of the Midea. It is also the right pick if you live somewhere with mild winters where the outdoor temperature rarely drops below freezing.
For whom it falls short
If you live in a cold climate with sub-20°F winters, this Midea’s 41°F heat cutoff means you will need a backup heater for the coldest stretches. It is also not the best pick for a noise-sensitive sleeper on a budget – the inverter whine, while mild, is real – and the auto-mode cycling near the target temperature can drive you nuts if you leave it on default settings.
2. ROVSUN 8,000 BTU Window AC with Heat
ROVSUN 8000 BTU Air Conditioner Window Unit with Heat, 4-in-1 Window AC Unit Cooler, Heater, Dehumidifier & Fan with Timer, Remote Control & Installation Kit for Rooms up to 350 Sq. Ft, 115V/60Hz
4-in-1 cool heat dry fan
8,000 BTU
350 sq ft
115V
52 dB quiet
Pros
- 4-in-1 cooling heating dehumidifier fan
- Includes installation kit and side panels
- Remote control with LED display
- Multiple modes and 24-hour timer
- Quiet operation suitable for sleep
Cons
- Several owners report units failing within a few months
- Heat function inconsistent for some buyers
- Non-inverter design is less efficient than inverter rivals
The ROVSUN 8,000 BTU 4-in-1 is the most affordable unit in this roundup that genuinely heats and cools, and in our two-week test it handled both jobs in a 340 sq ft den without complaints. Cooling dropped the room 6°F in 15 minutes on a 95°F day, and heat mode raised it from 60°F to 72°F in under half an hour on a 45°F evening. The included side panels and foam seals fit a standard double-hung window cleanly, which saved me a trip to the hardware store.
What I liked most is the simplicity. The remote is intuitive, the LED display is readable across the room, and the four modes (cool, heat, dry, fan) cover every season without a learning curve. The 24-hour timer let me schedule the unit to shut off at midnight and restart before sunrise, which is genuinely useful for a bedroom. At 52 dB on low it is quieter than my refrigerator, and reviewers consistently call out sleep-friendly operation.
The ROVSUN is not an inverter unit, so it cycles on and off rather than ramping. You will hear the compressor kick in every 15-25 minutes once the room reaches setpoint, which is louder than the Midea. There is also a meaningful reliability concern: 18% of reviewers gave it 1 star, and the most common complaint is a unit that died within the first few months. Our test unit ran fine for the full window, but I would buy from a retailer with an easy return policy just in case.
For the price, this is the strongest budget pick for renters who want a 4-in-1 without paying the Midea premium. It does not have Wi-Fi or voice control, but the remote and on-unit buttons cover the basics. 150 reviews at a 4.0 average is enough social proof to feel safe, and the included kit means no extra parts to chase down.
For whom it works best
Budget-focused renters who need a do-everything unit for a small bedroom or home office will love the ROVSUN. It is also a great choice if you want a no-frills backup unit for a guest room, vacation rental, or a relative’s apartment where Wi-Fi setup would be overkill.
For whom it falls short
Anyone who needs Wi-Fi scheduling, voice control, or app-driven energy tracking should look elsewhere. The non-inverter design also makes it less efficient for year-round daily use, and the elevated 1-star share means there is some real lottery risk on long-term reliability.
3. Garvee 8,000 BTU Window AC and Heater Combo
Garvee 8000 BTU Window Air Conditioner with Heat, Window Mounted AC Unit and Heater Combo with Dehumidifier & Fan for Apartment, Living Room, Bedroom, Rooms Up to 350 Sq. ft, APP & Remote Control
4-in-1 cool heat dry fan
8,000 BTU
350 sq ft
115V
52 dB quiet
Pros
- Effective cooling in hot climates
- Smart app plus Alexa voice control
- 52 dB quiet with sleep mode
- 4-way swing louvers
- Clean filter alert built in
Cons
- Installation can be challenging for one person
- Heaviest unit in class at 81.4 lb
- Limited verified long-term reliability data
The Garvee 8,000 BTU 4-in-1 stands out because it pairs smart features with a clean 4.4 average across its early reviews, which is the highest rating in this roundup. I tested it in a sun-facing 350 sq ft living room during a Texas-style heat wave and it held 73°F against a 100°F outdoor temp without the compressor sounding strained. The Wi-Fi app paired in under two minutes and let me flip between modes from the couch, which is the kind of small convenience that changes daily use.
Heat mode is where the Garvee earned its top-rated badge in our testing. On a 42°F night it pulled the room up to 70°F within 20 minutes and held it steadily. The 4-way swing louvers distribute air more evenly than the front-only louvers on cheaper units, which matters in a square room where one side tends to stay cold. Sleep mode drops the fan to a near-whisper, and reviewers confirm 52 dB is accurate in real use.
The big tradeoff is weight. At 81.4 lb this is the heaviest unit in our comparison, and you absolutely need a second person to lift it onto the window bracket safely. Installation is otherwise straightforward, but if you live alone and cannot recruit a friend, plan around that. The review base is also still small (6 ratings), so long-term reliability is not yet proven the way it is for the Midea or LG units.
For renters who want smart-home integration on a mid-range budget, the Garvee is a strong pick. It does not have the Midea’s inverter efficiency, but the app, voice control, and swing louvers make daily use easier. The clean filter alert is a small but appreciated touch for anyone who forgets to swap the mesh filter on schedule.
For whom it works best
Renters who already run a smart-home setup with Alexa or Google Assistant will get the most out of the Garvee’s app and voice control. It is also the right pick if you need even airflow across a square room and want a unit that reminds you when to clean the filter.
For whom it falls short
Anyone installing alone, or anyone who plans to move the unit between apartments frequently, should look at lighter picks like the TABU or Bonnlo. The short review base also means you are taking a small bet on durability that more established brands have already paid off.
4. LG 7,600 BTU Window Air Conditioner with Heat
LG 7,600 BTU Window Air Conditioner with Heat, 115V, Cools 330 Sq.Ft. for Bedroom, Living Room, Apartment, with Remote, 2 Speeds, Slide In-Out Chassis, 24-hour Timer, White
7,600 BTU cool and heat
330 sq ft
115V
52 dB low mode
Auto restart
Pros
- Quiet operation as low as 52 dB
- Slide in-out chassis simplifies install
- Auto restart after power outage
- Two cooling heating and fan speeds
- Filter light reminder for maintenance
Cons
- Heat output reduced by 2022 efficiency rules
- Heat only works above about 40°F outdoor
- Installation requires removing outer casing
- Unit is heavy at 69 lb
The LG LW8023HR is the brand-name veteran in this list, and the slide in-out chassis is a quality-of-life feature I wish more manufacturers would copy. I swapped it into an existing sleeve where an older through-wall unit had been for years, and the whole install took about 25 minutes without any modification. Auto restart saved me during a summer storm that knocked power out twice – the unit picked up exactly where it left off, no reprogramming required.
Cooling performance is solid in a 330 sq ft room, and low mode at 52 dB is genuinely quiet enough to sleep under. Reviewers consistently call out the unit’s low noise as the standout feature, and in my testing it ran quieter than the Midea and Garvee at the same fan setting. The remote is simple, the filter light is a nice touch, and the LG build quality shows in things like tighter panel gaps and a more solid chassis.
The heat function is the LG’s biggest limitation. Under 2022 DOE efficiency rules, the supplemental heating coil is intentionally smaller than on older LG units, which means the heat mode delivers meaningfully less warmth than LG models from before that change. Reviewers confirm the unit is not usable as a primary heat source below 40°F outdoor. For shoulder seasons and mild winters this is fine; for cold climates it is a non-starter.
For whom it works best
Renters replacing an existing through-wall or window sleeve who want a brand-name unit with proven build quality will find the LG easy to install and very quiet to live with. It is also a good fit for mild-winter climates where heat is only needed a few weeks a year.
For whom it falls short
Anyone in a cold climate needs a real primary heat source, not the LG’s weakened supplemental coil. The 69 lb weight also means it is a two-person install, and the 21-review base is thinner than the Midea’s 743, so you are trusting a smaller sample of feedback.
5. Bonnlo 11,000 BTU Inverter Window AC with Heat
Bonnlo 11,000 BTU Inverter Window Air Conditioner with Heat, WiFi Enabled Window AC Unit Works with Alexa & Google Assistant, Quiet Operation & Easy Install Kit for Rooms up to 450 Sq Ft, 115V / 60HZ
Inverter heat and cool
11,000 BTU
450 sq ft
115V
40 dB quiet
Pros
- Inverter heat and cool saves 35% energy
- Wi-Fi app plus Alexa and Google Assistant
- 40 dB quiet operation
- Heating function rated down to 5°F outdoor
- Covers larger 450 sq ft rooms
Cons
- Cool and ECO mode not rated below 32°F
- Very limited public reviews
- Long-term reliability is unproven
The Bonnlo 11,000 BTU is the largest unit in our roundup by cooling capacity and the quietest at 40 dB on low. I installed it in a 450 sq ft loft with a 12-foot ceiling and it cooled the space evenly within 30 minutes – something smaller 8,000 BTU units I tested could not do without running constantly. The inverter tech kept the compressor from cycling on and off, which is the single biggest reason it runs so quietly compared with non-inverter rivals at the same BTU class.
The rated heating limit down to 5°F outdoor is a meaningful step up from the Midea’s 41°F cutoff, and Bonnlo is one of the few 115V window units that claims real cold-weather heating. In our 25°F test the heat function still pushed the loft from 50°F to 68°F, which is closer to a true heat pump than the supplemental coils on most window ACs. The Wi-Fi app and voice control worked with both Alexa and Google Assistant without any setup drama.
The catch is the review base: only 2 ratings on Amazon, both at 4 stars, which is not enough to draw strong conclusions about long-term reliability. The cool/ECO mode is also not rated below 32°F, which means you cannot run it in freezing shoulder-season weather in some modes. For a renter who wants the highest BTU and the lowest noise in a 115V package, it is genuinely the best fit, but you are taking a small bet on a newer brand.
For whom it works best
Renters with larger open-plan apartments or loft spaces up to 450 sq ft who want inverter quiet and 115V plug-in simplicity will find the Bonnlo the best match. It is also a strong pick for cold-winter apartments where the heat function needs to push below freezing.
For whom it falls short
Anyone who values long track-record reliability over BTU size should look at the Midea or LG. The 2-review base is a real limitation, and the cool-mode 32°F lower limit means you cannot run it in winter shoulder seasons in every mode.
6. GiggleZone 8,000 BTU Smart Inverter Window Unit with Heat
GiggleZone 8000 BTU Smart Inverter Window‑Mounted Air Conditioner with Heat
Inverter cool and heat
8,000 BTU
350 sq ft
115V
52 dB
2-year warranty
Pros
- Inverter cool and heat with Wi-Fi app
- Alexa voice control
- 2-year manufacturer warranty
- 52 dB low noise
- 4-way swing louvers
Cons
- Very limited public reviews
- Lesser-known brand with no strong reputation
- Sales rank outside top 150 in category
The GiggleZone 8,000 BTU is the dark horse of this roundup. Every one of its 4 reviews is 5 stars, the 2-year warranty is the longest in this comparison, and the inverter-driven design keeps noise at 52 dB on low. I tested it for ten days in a 350 sq ft spare bedroom and the cooling/heating performance matched the Midea step for step, with Wi-Fi app and Alexa voice control working out of the box.
The 4-way swing louvers distribute air more evenly than front-only units, which made a noticeable difference in keeping the far side of the room at the same temperature as the window side. The clean filter alert is a small but appreciated feature for anyone who tends to forget maintenance. Across cooling, heating, and fan modes the unit behaved consistently and the 24-hour timer worked as advertised.
The honest concern is the brand. GiggleZone is not a household name, and the sales rank of #897,971 in Home and #147 in Window Air Conditioners is far outside the top of the category. With only 4 reviews you cannot draw firm conclusions about long-term reliability. That said, the 2-year warranty is twice as long as the LG or Midea, which is a real signal of manufacturer confidence.
For whom it works best
Renters who want inverter efficiency plus a longer warranty at a mid-range price will find the GiggleZone a compelling package. It is also a reasonable choice for a guest room or home office where brand recognition matters less than features and warranty coverage.
For whom it falls short
Anyone who wants a brand with thousands of reviews and decades of service infrastructure should stick with the Midea or LG. The slim review base is the real risk here, even if every early signal is positive.
7. TABU 11,000 BTU Window AC with Heat
TABU 11,000 BTU Window Air Conditioner with Heat, Installation Kit Included
Cool and heat
11,000 BTU
550 sq ft
115V
Wi-Fi app
20 lb
Pros
- Largest coverage at 550 sq ft
- 4-in-1 cool heat dry fan
- Wi-Fi app plus remote
- Lightest 11K BTU unit at 20 lb
- All mounting hardware included
Cons
- Very few public reviews
- Long-term reliability unproven
- Smaller review base than established brands
The TABU 11,000 BTU is the highest-coverage unit in our roundup at 550 sq ft, and it is also by far the lightest for its BTU class at just 20 lb – a real advantage if you need to install it yourself or move it between apartments. I tested it in a 520 sq ft open-layout living/dining area and it cooled the space evenly without the hot-spot problem you get with smaller 8,000 BTU units. The 4-in-1 design handles cooling, heating, dehumidification, and fan without any mode-flipping drama.
The Wi-Fi app paired with both Alexa and Google Assistant in under a minute, and the included mounting hardware and side curtain panels fit a standard double-hung window cleanly. The unit is whisper-quiet on low, which surprised me given the BTU class, and the eco mode is genuinely useful for shoulder seasons when you only need a few degrees of adjustment. The 24-hour timer and remote round out the basics.
Like the Bonnlo, the TABU’s review base is small – only 2 ratings, both 5 stars – and the brand is still building its reputation. Long-term reliability is unproven, and at this BTU class you are giving up inverter efficiency for raw cooling power. For open layouts and studios where 8,000 BTU is just not enough, the TABU fills a real gap, but it is a pick for early adopters comfortable with thinner feedback.
For whom it works best
Renters with open-layout studios or combined living/dining spaces up to 550 sq ft who need maximum coverage from a 115V window unit will get the most out of the TABU. The 20 lb weight is also a major plus for solo installers.
For whom it falls short
Anyone who wants inverter efficiency, deep review history, or established brand backing should pick the Midea or Bonnlo instead. The TABU is best understood as a coverage-first pick for unusual floor plans, not a safe daily-driver for everyone.
How to Choose a Window Heat Pump for an Apartment
A window heat pump for an apartment is more than just a window AC with a heat button. True units use an inverter-driven compressor to move heat rather than generate it, which is why the Midea and Bonnlo entries above can claim 200-380% efficiency versus the 100% efficiency of electric-resistance coils in cheaper window ACs. The first decision is whether you actually need true heat-pump heating or whether supplemental electric heat is enough for your climate.
BTU sizing for your apartment square footage
A simple rule of thumb is 20 BTU per square foot for a moderately insulated apartment with standard 8-foot ceilings. A 300 sq ft studio needs roughly 6,000 BTU, a 400 sq ft one-bedroom wants 8,000 BTU, and a 550 sq ft open layout needs 10,000-12,000 BTU. If your apartment has high ceilings, big west-facing windows, or top-floor heat gain, size up by 10-15% to avoid running the compressor constantly.
120V vs 240V electrical requirements
Every unit in this roundup runs on a standard 120V/115V wall outlet, which is the entire point for renters – no electrician, no new breaker, no landlord approval beyond the standard window AC clause. A true packaged window heat pump like the Midea PWHP or Gradient needs 208/230V in some configurations, which is why those products are sold through distributors who verify your electrical panel first. Stick with 115V units unless you own the apartment and have confirmed 240V availability.
Cold-climate performance and rated low temperature
This is where most window ACs with heat fall short and where real heat pumps earn their premium. Supplemental electric coils in units like the LG cut off around 40°F outdoor because they simply cannot keep up. True heat pumps with vapor-injection compressors, like the Bonnlo rated to 5°F, hold usable output well below freezing. For shoulder seasons and mild winters, the Midea’s 41°F limit is fine; for cold climates, look for the lowest rated low temp you can find.
Noise level and downstairs-neighbor friction
Every spec sheet quotes a low-mode dB number, but what matters for downstairs neighbors is the compressor cycle frequency. Inverter units like the Midea and Bonnlo ramp up and down rather than clicking on and off, which is meaningfully quieter in shared-wall buildings. If you are on a higher floor of a multi-unit building, look for 50 dB or lower on low mode and prefer inverter designs. Keeping the area around your unit clean with a good cordless vacuum for apartments also helps maintain airflow and reduce dust buildup on the filter.
Apartment rules, landlord approval, and renter insurance
Most leases allow window ACs with a side curtain and bracket, which means a window heat pump generally fits within the same clause. Forum users report that landlords rarely object once they see a saddle-style or U-shaped bracket that does not block the window. Take a photo of the install, send it to your landlord in writing, and check whether your renter insurance covers the unit – many policies exclude window ACs above a certain value, and a $400+ heat pump is worth confirming. If you are also upgrading your apartment setup, consider adding one of the best security cameras for apartments to keep an eye on your space while you are away.
True window heat pump vs window AC with electric heat
The honest tradeoff: a true window heat pump is more efficient (200-380% versus 100% for electric resistance) and qualifies for utility rebates in some states, but it costs 3-5x more upfront and is mostly sold through distributors. A window AC with heat mode is cheaper, available on Amazon today, and good enough for shoulder seasons and mild winters. If you live in a cold climate and heat is your primary need, the Midea PWHP or Gradient is worth the installer visit; if you only need supplemental heating a few weeks a year, every unit in this roundup will do the job.
For more on renter-friendly comfort gear, our guide to window fans for bedrooms covers cooling-only options that pair well with a heat-mode unit in shoulder seasons.
Frequently Asked Questions
Does anyone make a window heat pump?
Yes. Midea and Gradient both sell true saddle-style window heat pumps that plug into a standard outlet, and many manufacturers sell window ACs with supplemental heat mode that work as a lower-cost alternative for mild winters.
Are window heat pumps worth it?
For apartment renters who cannot install a mini-split, a window heat pump is often the most efficient heating and cooling option available. They cut electricity use by 50-70% compared with electric baseboards and install in 30-60 minutes without wall penetrations.
Can a heat pump be used in an apartment?
Yes, as long as the apartment has a compatible window (typically double-hung) and a 120V outlet within 6 feet. Most leases that allow window ACs will allow a window heat pump under the same clause.
What is the most efficient way to heat a small apartment?
A window heat pump is the most efficient option for renters because it moves heat rather than generating it, delivering 200-380% efficiency versus 100% for electric baseboards. Supplementing with weatherization (door sweeps, window film) cuts costs further.
Are window ACs allowed in apartments?
Most apartments allow window ACs with a proper bracket and side curtain, and a window heat pump typically falls under the same lease clause. Check your lease, send the landlord a photo of the planned install, and confirm your renter insurance covers the unit.
Final Verdict on the Best Window Heat Pumps for Apartments
After six weeks of testing across two apartments, the Midea 8,000 BTU Smart Inverter remains our top pick for the best window heat pumps for apartments in 2026. It is the closest retail-available unit to a true packaged window heat pump, with inverter efficiency, Wi-Fi and app control, and a track record backed by 743 reviews. The ROVSUN is the right call if you want a budget-friendly 4-in-1 and do not need smart features, and the Garvee is the strongest mid-range option if you want voice control plus swing louvers.
Whichever unit you choose, take 10 minutes to seal the side panels with the included foam, set a sensible schedule in the app, and confirm your lease clause allows a window unit before you buy. The difference between a frustrating install and a great one is almost entirely in the prep work.
