Our top pick is the **[BLACK+DECKER Smart Portable Air Conditioner with Heat, 14,000 BTU](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-1)**, a four-in-one unit with a phone app that its listing covers to 700 sq ft. We read 44 Amazon result cards for “portable air conditioner and heater”, set aside the 12 sponsored ones and opened 10 product pages. Five passed our test and five were left out. Then one pick for each other need. For a quiet dual-hose inverter, the **[SereneLife 12,000 BTU Inverter Portable Air Conditioner Heater with Wi-Fi](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-2)**. For a slim tower with heat-pump heating, the **[Hisense Smart Inverter Twin Hose 8,000 BTU Heat/Cool Tower Portable Air Conditioner](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-3)**. For a four-mode unit with a large dehumidifier, the **[Westinghouse Portable Air Conditioner with Heat Mode](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-4)**. For a small room, the **[SereneLife 8,000 BTU Portable Air Conditioner and Heater with Wi-Fi](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-5)**. Here, a combo is a portable unit that stands on the floor, vents through a hose in a window, and whose listing says it both cools and heats. Cool-only units, window units, space heaters and fans are not picks. BTU figures and room sizes below are the listing's own wording, not ours. ## How to choose a portable air conditioner and heater combo Air Conditioner Lab and Bob Vila agree on the points that matter most. - **Match the BTU to the room.** Air Conditioner Lab suggests 5,000 to 8,000 BTU under 200 sq ft, 8,000 to 12,000 BTU for 200 to 400 sq ft and 12,000 to 14,000 BTU for 400 to 600 sq ft, and says ceiling height, insulation and window size shift those numbers. The [Westinghouse Portable Air Conditioner with Heat Mode](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-4) lists 700 sq ft, the [SereneLife 8,000 BTU Portable Air Conditioner and Heater with Wi-Fi](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-5) 350 sq ft. - **Read the heating BTU separately.** Air Conditioner Lab says a combo's heating BTU runs lower than its cooling BTU, by 5 to 15 percent on average. The [BLACK+DECKER Smart Portable Air Conditioner with Heat, 14,000 BTU](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-1) lists 14,000 BTU (ASHRAE) cooling and 10,000 BTU heat. - **Single hose or dual hose.** Bob Vila says a single-hose unit cools its condenser with room air, which wastes energy, while a dual-hose unit draws outdoor air and is more efficient, especially in a larger space. The [SereneLife 12,000 BTU Inverter Portable Air Conditioner Heater with Wi-Fi](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-2) and the [Hisense Smart Inverter Twin Hose 8,000 BTU Heat/Cool Tower Portable Air Conditioner](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-3) both list two hoses. - **Noise.** Bob Vila puts the average unit at 50 to 60 decibels and the quietest at 40 to 45. Air Conditioner Lab warns that a maker's decibel figure can be optimistic. The SereneLife inverter lists 44 to 49 dBA and the small SereneLife unit 55 dBA. - **Weight and where it lives.** Bob Vila's table runs from about 57 to 77 pounds, so check the wheels and where the unit sits out of season. ## Our picks in detail ### 1. BLACK+DECKER Smart Portable Air Conditioner with Heat, 14,000 BTU: best for a large room **Why it made the list** - Its listing names 14,000 BTU (ASHRAE) cooling, 10,000 BTU of heat and a four-in-one design with a dehumidifier and fan. - It lists coverage for rooms up to 700 sq ft and a window installation kit. - It lists Wi-Fi with voice control and a Follow Me remote that acts as a thermostat. - Amazon's own summary lists installation as positive, and Amazon marks it a Best Seller in portable air conditioners. **Drawbacks** - Amazon's own summary lists durability as negative, with owners reporting the unit breaking within a year. - It lists cooling performance, noise, reliability and value as mixed, and a 3-star snippet says it did not cool a 20 ft container below 85 degrees on a 100 degree day. **Watch for this:** BLACK+DECKER also sells a 14,000 BTU model without heat under a separate listing with its own total, so check that the title says “with Heat”. **Skip it if** you want a quiet unit or one with a long service record. ### 2. SereneLife 12,000 BTU Inverter Portable Air Conditioner Heater with Wi-Fi: best dual-hose inverter **Why it made the list** - Its listing names a dual-hose design and DC inverter technology, which it says cool faster than a single-hose unit. - It lists cool, heat, fan and dehumidifier modes and 12,000 BTU of cooling. - It lists a noise level of 44 to 49 dBA and Wi-Fi control through an app. - Amazon's own summary lists cooling performance and power as positive. **Drawbacks** - Amazon's own summary lists performance and value for money as mixed, from only a handful of mentions. - A 3-star snippet says a 14,000 BTU unit's manual lists 10,300 BTU, and a 2-star snippet says the fan is weak. **Watch for this:** the 12,000 BTU and 16,000 BTU listings of this inverter show one shared total, so they are sizes of one unit. SereneLife's non-inverter units are a different line with a different shared total. **Skip it if** you want a long record of owner feedback, since its summary rests on few mentions. ### 3. Hisense Smart Inverter Twin Hose 8,000 BTU Heat/Cool Tower Portable Air Conditioner: best slim tower **Why it made the list** - Its listing names a twin-hose tower with heat-pump technology for supplemental heating. - It lists a vertical fan that throws air up to 21 feet at 60 degrees and a self-evaporating drain. - It lists 8,000 BTU (DOE) cooling for 350 sq ft and a variable-speed inverter motor. - Amazon marks it Amazon's Choice, and its summary lists cooling performance, noise and portability as positive. **Drawbacks** - Amazon's own summary lists value for money, the remote control and size as mixed, with one owner finding it preposterously large. - A 3-star snippet praises the cooling but could not speak to the heat yet, and a 1-star snippet says a 5,000 BTU window unit did better. **Watch for this:** its review total is small, so one bad batch moves its figures fast. **Skip it if** you need to heat or cool more than 350 sq ft. ### 4. Westinghouse Portable Air Conditioner with Heat Mode: best four-mode unit **Why it made the list** - Its listing names air conditioner, fan, dehumidifier and heater modes. - It lists a dehumidifier that removes 90 pints of moisture a day and an install of about five minutes. - It lists 12,000 BTU (ASHRAE) cooling for areas up to 700 sq ft. - Amazon's own summary lists cooling performance, installation and features as positive. **Drawbacks** - Amazon's own summary lists durability as negative, with owners reporting units that break just outside the warranty window. - It lists noise, value, compatibility and water capacity as mixed, and a 1-star snippet says the unit does not self-drain with a garden hose. **Watch for this:** the title says 14,000 BTU while the first bullet says 12,000 BTU ASHRAE, which is why the table shows the bullet's number. **Skip it if** you need a window adapter that fits an odd window, since a snippet calls it not broadly compatible. ### 5. SereneLife 8,000 BTU Portable Air Conditioner and Heater with Wi-Fi: best for a small room **Why it made the list** - Its listing names 8,000 BTU cooling for up to 350 sq ft and dehumidifier, heater and fan modes. - It lists a universal window mount kit and a self-evaporating system. - It lists low-noise operation at 55 dBA and built-in Wi-Fi. - Amazon's own summary lists installation and power consumption as positive. **Drawbacks** - Amazon's own summary lists Wi-Fi connectivity as negative, with several owners unable to connect. - It lists cooling performance, performance and noise as mixed, and two snippets say the unit stopped cooling within days. **Watch for this:** its 8,000 and 10,000 BTU listings share one total, so a snippet may describe the other size. **Skip it if** your room is over 350 sq ft or you want an app that connects reliably. ## What we left out, and why We read 44 result cards across two pages of “portable air conditioner and heater”. 12 were sponsored, and we skipped them. The other 32 were 32 different listings, and several models appear under more than one listing. We chose 10 contenders by review count and kept only titles that name heat. Five passed and five were left out: - **SereneLife 12,000 BTU with Built-in Dehumidifier (B07RN1GRBQ).** The most reviewed, but its 13.2K total is shared with SereneLife 14,000 and 16,000 BTU dual-hose models, and a 1-star snippet on it describes a 14,000 BTU unit. That is a pooled total, so it is not a pick. - **BLACK+DECKER 12,000 BTU with Heat (B072B8SGKY).** A smaller sibling of the [BLACK+DECKER Smart Portable Air Conditioner with Heat, 14,000 BTU](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-1) with the same bullets, and its summary lists durability as negative. - **BLACK+DECKER 14,000 BTU with 12,000 BTU Heating (B08NWBXLB7).** A second 14,000 BTU unit for the same need as pick 1, and its summary lists heating as mixed. - **Midea 14,000 BTU with Heat (B0DQWXDDPZ).** A third 14,000 BTU unit, and its summary lists reliability and leakage as negative. - **Whirlpool 14,000 BTU with Heater (B0CYQHVR3V).** Its review total is very small, too few to lean on, and it covers the same need as picks 1 and 4. We did not read a Wirecutter page for this topic. Air Conditioner Lab's top pick is a Whynter dual-hose combo and Bob Vila's best overall is a Midea Duo with heat; neither was among the ten pages we read. ## Questions people ask ### What size portable air conditioner and heater fits my room? Air Conditioner Lab matches BTU to floor area: 5,000 to 8,000 BTU under 200 sq ft, 8,000 to 12,000 BTU for 200 to 400 sq ft and 12,000 to 14,000 BTU for 400 to 600 sq ft. Ceiling height, insulation and window size change that. The [SereneLife 8,000 BTU Portable Air Conditioner and Heater with Wi-Fi](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-5) is the small one here. ### Does the heat mode heat as well as it cools? Not by the numbers. Air Conditioner Lab says combos list a lower heating BTU than cooling BTU, by 5 to 15 percent on average. The [BLACK+DECKER Smart Portable Air Conditioner with Heat, 14,000 BTU](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-1) lists 14,000 BTU (ASHRAE) of cooling and 10,000 BTU of heat. ### Is a dual-hose unit better than a single-hose one? Bob Vila says a dual-hose unit is more efficient because it draws outdoor air to cool its condenser, and calls it the wiser option for larger spaces. Air Conditioner Lab says a single-hose unit works well in a room under about 350 sq ft. The [SereneLife 12,000 BTU Inverter Portable Air Conditioner Heater with Wi-Fi](https://twelvetabs.com/reviews/best-portable-air-conditioner-heater-combos/#pick-2) is the dual-hose pick. Only need one season? Our [window air conditioners guide](https://twelvetabs.com/reviews/best-window-air-conditioners/) covers cooling, and our [space heaters guide](https://twelvetabs.com/reviews/best-space-heaters/) covers heat. ### How did TwelveTabs choose these portable air conditioner and heater combos?
