The best portable air conditioner and heater combination units are true heat pumps. This means that the same technology is used for air conditioning and heating – refrigerant collecting heat in one location and the unit pumping it to another.

This Portable Air Conditioner with Heat Guide lists the top portable air conditioner heat pumps, gives overviews for you to quickly browse and buy if you’d like, plus full reviews with greater details about features, pros and cons.

The Best Portable AC and Heater Combination Models

The best portable air conditioner heat pumps are:

  • Honeywell MN14CHCS MN Series Portable Air Conditioner
  • Whynter ARC-14SH Portable Air Conditioner
  • SereneLife Portable Air Conditioner
  • Black + Decker BPACT12HWT Portable Air Conditioner
  • Honeywell 12,000 BTU Portable Heat/Cool Air Conditioner

Overviews of the Top Portable AC Heat Pumps

Here are the top models with essentials listed in bullet points. If you’re in a hurry, want to decide on a model and get on with your day, these overviews are exactly for that purpose. Full reviews follow.

All Units Have 4 Modes: AC, Heat, Dehumidify and Fan-only.

Important Note on BTUs: For portable air conditioners, there are two BTU ratings. The old rating is called ASHRAE; the updated rating is from the DOE (Department of Energy) called Seasonally Adjusted Cooling Capacity, or SACC. The DOE rating is generally about half the other for single-hose models, a little higher for dual-hose portable ACs.

Why? Because portable ACs pull heat into your home when exhausting heat from your home. We list the ASHRAE rating first, and the DOE rating second, if it is available.

Portable AC Heat Pump Full Reviews

If you’re still here, it means you want more information about each of these units.

We’ve selected the best 6 portable air conditioners with heat – true heat pumps. There are other models available, but their quality and performance isn’t up to PickHVAC standards.

Single-hose vs Dual Hose

There are two advantages to a dual hose model:

  • Greater efficiency, since they pull less warm air into your home through drafty doors and windows.
  • Greater cooling capacity for the size. Note that the single-hose 14,000 BTU models have a DOE/SACC rating of 7,500. The 14K BTU Whynter is dual-hose and has a DOE/SACC rating of 9,500 BTUs. That’s a lot more AC and heating power for the same size unit.

Room Size

Don’t be fooled by the marketing done by portable air conditioner/heat pump manufacturers. They use the outdated ASHRAE ratings for how many square feet a portable AC can cool.

This chart is more in line with reality!

 OK, here are the complete reviews of the top portable air conditioners with heat pump technology for cooling and heating.

#1 Honeywell MN14CHCS MN Series Portable Air Conditioner

Best Overall

Honeywell has made quality appliances for decades, improving its game in the last few years after a bit of a drop-off.

This unit uses auto-evaporation, which means in AC mode, the moisture it pulls from the air is exhausted out the hose, not drained into a reservoir that then must be emptied.

Note: This review is longer than the others because some features common to all are explained in it, but just mentioned in the others.

Honeywell MN14CHCS MN Series Portable Air Conditioner

Why it is One of the Best: This is a well-built unit with the highest ratings of any on the list. Honeywell portable heat pumps have features necessary for excellent indoor climate control.

Size: 14,000 / 7,500 BTUs

Zone Size: About 400 square feet

Features: This unit, like the others, has four operational modes for improved climate control in all weather.

  • AC – Air conditioning for warm months also removes humidity for cooler, drier air.
  • Heat – True heat pump technology is more efficient than a space heater = it costs much less to run.
  • Dehumidifier – On cool, clammy days, used the Dehumidifier mode to dry the air without making it chilly. Note, however, that you’ll have to attach a drain hose and run it to an indoor floor drain in Dehumidifier mode (true for many portable air conditioners).
  • Fan-only – This mode is ideal for moving musty air or for white noise.
  • Caster wheels make moving it easy.
  • Digital thermostat for accurate temperature control.
  • LED Touch Control
  • Auto-Evaporation (Bucket-free)
  • Full-function Remote
  • Multi-speed fan.
  • Local US phone support, if needed.

Pros: 4 modes, removes 86 pints (10.75 gallons) per day in AC and Dehumidifier modes. Very good quality. Bright LCD touch display.

Cons: The single-hose design limits its cooling power, which is true of all the models in this list except for the Whynter portable air conditioner.

User Comments: This is a section where we briefly list comments from multiple verified users separated by …: Serves a 600 square foot, well insulated area…Cold air immediately…I use it in a South Florida room (350 square feet) with no AC, and it does pretty well except for on very hot afternoons…It’s a little loud…Heat well in a room that always used to be cold in winter (in MN).”

Bottom Line: Consider this Honeywell portable heat pump if you want a quality unit that will serve your home in all four seasons.

#2 Whynter ARC-14SH Portable Air Conditioner

Best Dual Hose Model

Whynter makes quality products, and this one gets good marks from reviews and those who have one in their home.

The unit received Consumer Report’s 2020 highest scorn. It also won Good Housekeeping’s 2020 Best Overall award in the portable air conditioner category. We considered it for our Top Model too, and it certainly is equal to the unit we chose.

Whynter ARC-14SH Portable Air Conditioner

Why it is One of the Best: Not only is it highly rated, it is a dual hose model. This means it cools quickly and more efficiently than single-hose portable air conditioners. Plus, it serves a larger area – by about 150 square feet.

Size: 14,000 / 9500 BTU

Zone Size: Up to 500 square feet.

Features: Dual hose – one of intake and one for exhaust – makes the unit more efficient and able to cool a larger area. It heats better too for the same reasons.

  • 4 Modes: AC, Heat pump, Dehumidifier and Fan-only.
  • 3 fan speeds.
  • 24-hour timer.
  • R32 refrigerant has no CFCs, so it doesn’t damage the ozone. It also has a lower global warming potential than R410A, the most commonly used portable air conditioner refrigerant.
  • Activated carbon filter helps eliminate odors. The unit has a standard dust filter too.
  • 9-gal Daily Moisture Removal (AC)
  • 24-Hr Timer & Full Remote

Pros: The efficiency of this unit is the best on this list and one of the best of any portable air conditioner on the market. It’s full of features and friendlier to the environment than most units.

Cons: It’s a little costlier than some, but the lower efficiency will pay you back in a few years through lower energy costs.

User Comments: “Lowered my energy bills with this unit!…Cools faster than the single hose unit we had before…air feels cooler and drier after just a few hours in 90 degree Atlanta weather…Mine is 6 years old and working well…Mine arrived damaged.”

Bottom Line: If you’re willing to pay a little more to get faster cooling and heating and lower utility bills, this Whynter portable air conditioner should be on your short list.

#3 SereneLife Portable Air Conditioner

Best Small Portable AC with Heat

SereneLife is a brand that with proven quality and a growing crowd of enthusiastic consumers that have discovered it.

SereneLife Portable Air Conditioner

Why it is One of the Best: It is the best 10,000 BTU portable air conditioner/heat pump on the market. This unit is loaded with convenience and climate control features.

Size: 10,000 / 5,500 BTUs

Zone Size: Best for about 300 square feet, a little more if the room is well-insulated and doesn’t face south or west, a little less space if it does.

Features: This unit has the 4 modes – AC, Heat, Fan-only and Dehumidifier.

  • Multiple fan and cooling levels.
  • 24 Hour Timer.
  • Multiple Fan/Comfort Settings.
  • Remote with all the major functions on it, so there’s no need to get up to adjust the settings.
  • Moving wind vents for better air circulation to the furthest reaches of the room.
  • 5-foot hose.
  • Removes about 3 pints per hour in AC or Dehumidifier Modes.

Pros: Good features, compact size ideal for rooms where floor space is tight. Decent moisture control for a unit its size. It’s quiet at 52-56 decibels. The evaporative function means it rarely has to be drained in AC mode.

Cons: The hose is a few inches shorter than most, so you have less flexibility in where to locate it.

User Comments: “Great for our South Carolina bedroom…too 15 minutes to get the window vent set up…It’s been running a month with no need for draining…Hose starting to rip after 4 mos.”

Bottom Line: If you have a smaller space of up to 325 square feet and don’t want to overwhelm it, this unit is a good fit.

#4 Black + Decker BPACT12HWT Portable Air Conditioner

Best Midsize Portable AC with Heat

This unit is the best 12,000 BTU portable air conditioner / heat pump available.

Black + Decker BPACT12HWT Portable Air Conditioner

Why it is One of the Best: Consumer ratings put this unit at or near the top in features and climate control. More than 8,000 units have been sold, so the high ratings aren’t artificial. It has a track record of quality performance.

Size: 12,000 / 6,500 BTU

Zone Size: 225 – 300 square feet depending on how warm/cool the room is to begin with, how well insulated it is and what direction the windows/walls face.

Features: One of the nice aspects of this model is that the window kit is suitable to sliding/vertical windows, not just single-hung and double-hung windows.

  • 4 Modes – AC, Heat, Dry and Fan.
  • 24-Hr Time.
  • Full-feature remote makes controlling it easy from across the room.
  • Sleep Mode saves energy.
  • Max Mode cools quickly.
  • 3-speed fan.

Pros: Good quality, use with sliding windows, good climate control and accurate temperatures. It’s an evaporative portable air conditioner, so you won’t need a drain in AC mode. The unit uses R600A isobutane refrigerant which has a lower global warming potential than most types.

Cons: You will need a drain if you use it in Dehumidifier mode. The 4’ 11” hose is shorter than most.

User Comments: “It’s quiet enough for our baby nursery, and the fan mode helps baby sleep…Comes on automatically after a power outage if it was on when the power went out…The tube comes out of the fixture kinda easy if you move the unit…

Bottom Line: If you have +/- 275 square feet to heat and/or cool, this unit has years of proven performance and a high rating average from a huge number of reviews.

#5 Honeywell MN12CHESWW Portable Heat/Cool Air Conditioner

Best Features

Honeywell makes the list again with a midsize portable air conditioner that should serve about 300 square feet, (not the “up to 550 square feet Honeywell claims). Keep in mind that if the information is going with the ASHRAE rating rather than the revised DOE capacity rating, it will be roughly 80% too high.

Honeywell 12,000 BTU Portable Heat/Cool Air Conditioner

Why it is One of the Best: It is loaded with features that allow you to control the indoor climate quite well in all seasons. For example, if your climate is very humid, consider this model. It has the ability to remove more than 8.5 gallons of moisture from the air per day. Now, that would be impossible in Arizona, but it could be done in the muggy SE US.

Size: 12,000 / 6,500 BTU

Zone Size: 300-400 square feet

Features: Has 4 modes – Air conditioning, Heat pump heating, Dehumidifier and Fan-only.

  • Dual air filters remove more allergens and dust from the air than most other models.
  • Oscillating vertical louvers does a good job distributing air.
  • 3-speed fan.
  • 24-hour timer.
  • Remote with total functionality.

Pros: Excellent indoor climate control – cooler and drier air in summer, and good warming potential in cold weather.

Cons: A little pricier than a couple others on the list.

User Comments: “Cools quickly and effectively in a 280 s.f. bedroom…room is less dusty using this 2-filter machine, but I need to clean the filters to be effective…uses more power than the 2-hose one I had before.”

Bottom Line: If you are an aficionado of indoor comfort, this unit is a good choice. It is available in a 10,000 BTU size with heat too. Click and pick your size, if interested.

#6 Vremi 12,000 BTU Portable Air Conditioner

Best Value

Like SereneLife, this brand isn’t a household name – but plenty of consumers have found its products and give them pretty good ratings. This one is a particularly good value – not just because the cost is lower.

Our definition of “value” is good quality combined with competitive cost. Any product must have both traits to make our list.

Vremi 12,000 BTU Portable Air Conditioner

Why it is One of the Best: Value and performance.

Size: 12,000 / 6,000 BTU

Zone Size: 300-350 square feet depending on how well insulated the space is. If you use it in an uninsulated garage, it won’t cool or heat nearly that much space. That’s just the reality with any air conditioner – any type, any size.

Features: This unit has 5 modes – Air conditioning, heating, dehumidifying, fan-only for moving air and providing white noise plus sleep mode. But keep something in mind about sleep mode on a window air conditioner or portable air conditioner: It raises the temperature in AC mode. Sure, this saves money, but if you like a cool, dry bedroom, keep it on standard AC mode.

  • Programable control panel makes it easy to set the thermostat and fan speed where you want it and forget it. It’s an easy-to-read LED display.
  • Compact remote control has all the features of the control panel.
  • 24-hour timer.
  • 5’ 6” hose is one of the longer hoses on this list.
  • Two-layer washable filter cleans the air more effectively than a single-layer filter. Vremi suggests weekly cleaning of the air filter – standard for any room AC.

Pros: A good value and decent features.

Cons: A drain hose is needed for AC and Dehumidifier modes. There’s no reservoir for condensate. The best method is to run a garden hose to a basement drain.

User Comments: “Great for a living room, but a little loud in the bedroom if you’re a light sleeper…Digital display can be dimmed at night (but it’s still a little bright, so I put a light cloth on it)…Great customer service! The first unit was damaged in shipping. Vremi replaced it and paid shipping. New unit arrived in a couple days.”

Bottom Line: If you have a convenient floor drain or don’t mind dumping this unit (if you use the drain plug to cap the port) and want to save money, this is a good unit. It’s a good choice for arid climates too where the drain issue won’t affect its performance.

Portable AC with Heat Buying Guide and Tips

There are a few things to think about as you consider and compare portable air conditioners to other options. We’ve done guides and hundreds of reviews on the most common alternatives:

Why Consider a Portable Air Conditioner?

There are a couple reasons a portable air conditioner might be a good choice for you.

Portable ACs vs Central Air Conditioning

This topic is covered more fully in our Portable AC Review and Buying Guide.

If your entire home needs air conditioning, and it is larger than 400 square feet (a portable air conditioner would be great for a tiny house), then central AC is preferred.

Homes with Central AC: However, even in air conditioned homes, a portable air conditioner can be useful. If the HVAC/central air system is underpowered and a room or two are left on the warm side (or cool in winter), then a portable AC/heat pump can provide the extra cooling and heating you need – much like a window air conditioner does in many homes.

Large Homes with AC: Let’s say you have a large house, but it’s largely empty. Instead of keeping the entire house at 75F, homeowners often set the thermostat to 80F. Then, in the rooms most used, like the kitchen and bedroom, a portable air conditioner is used to cool occupied areas.

Portable AC/Heat Pumps vs Window ACs

There are pros and cons when comparing portable air conditioner/heat pumps with window air conditioners.

Pro: A portable heat pump/air conditioner takes up less window space. If the unit will be used in a room with just one window, for example, then you’ll get a better view and more natural light with a portable air conditioner with heat.

Secondly, there are more options for portable heat pump air conditioners like the ones reviewed in this guide than there are window air conditioners with a heat function. And most true heat pump window air conditioners are very expensive. Most window air conditioners with heat have a heat coil – a space heater coil – for heat. Those units use a lot of electricity, so operating costs are a lot higher.

Con: A portable AC isn’t as efficient as a window air conditioner with the same ASHRAE rating. We explained the new DOE/SACC ratings that portable air conditioner manufacturers must include.

If you compare a 14,000 BTU window air conditioner to a 14,000 BTU portable air conditioner (ASHRAE ratings), in reality, the portable AC unit will really only provide about 7,500 BTUs of heating and cooling per hour.
