Aspects to Consider Before Buying a Model From Our List

Our list below consists of some of the best portable AC/heater combos you can find on the market. However, there are several things you need to take into consideration to be able to pick the right unit according to your needs. These include:

Cooling and Heating Capacity

The cooling and heating power of all portable AC/heater combos is measured in BTU’s (British Thermal Unit). Each unit has a specific capacity and your choice will mainly depend on the size of the space or room where you will be using the unit.

Therefore, you need to measure the size of your space beforehand so that you are able to correctly determine the number of BTUs required to cover the space and allow you to pick the right AC/heater combo. For instance:

  • A 200 sq. ft. space requires an 8,000 BTU unit
  • A 300 sq. ft. space requires a 10,000 BTU unit
  • A 400 sq. ft. space requires a 12,000 BTU unit
  • A 500 sq. ft. space requires a 14,000 BTU unit

In other words, the higher the BTUs, the more space the unit can cover. A higher BTU rating also means that the system is capable of cooling or heating the room faster.

Energy Efficiency

Portable AC/heater combos usually utilize less energy to cool or warm the surrounding air. Still, it’s essential to buy an energy efficient model that will perform well while keeping your utility expenses down.

Therefore, you should consider the energy efficiency ratio of the unit you are getting. Generally, the higher the EER rating, the better the energy efficiency of a unit, so a unit with a rating of ten would be twice as efficient at utilizing energy as one with a rating of five.

Unit Weight and Size

The weight of a portable AC/heater unit will significantly determine how portable it is. The weight of most units often ranges from 45 to 95 pounds. If you are going to move the unit up and down stairs, then you want to go for a lighter model.

Having a unit that takes up less floor space is also ideal. Therefore, you should consider the depth and width of the unit. Look for something in the range of 12 to 18 inches.


An adjustable thermostat is a feature that can come in handy as it lets you adjust the heater to your desired temperature. Therefore, with a unit that features a thermostat, you get the advantage of custom settings compared to one that does not have a thermostat.

Dehumidifying Feature

Most portable AC/heater units function as dehumidifiers to help eliminate any dampness from the air, providing a healthy atmosphere, as well as greater comfort.

Some of the units on our list have a dehumidification function built-in too. Not all models have it, so you should decide beforehand whether this is a must-have feature for the portable AC/heater unit you need or not.

5. Honeywell MM14CHCS

Honeywell MN Series Portable Air Conditioner with Heater, Dehumidifier, and Remote Control for a Room up to 700 Sq. Ft. (Black/Silver), MN14CHCS


  • Fan mode has three speeds
  • Has a high capacity dehumidifier
  • Easy to install, operate, and maintain
  • Delivers sufficient cooling and heating power
  • Relatively easy to cart around between rooms
  • Can work effectively in small, medium, and fairly large rooms


  • Lifting it is challenging because it has no handles ton the sides
  • Makes some noise when transitioning between cooling settings

The MM14CHCS is a top-of-the-line unit from the reputable Honeywell brand. This multi-functional model comes in third on our list not just because of its attractive modern look but also its collection of wonderful features.

The Honeywell MM14CHCS is a jack-of-all-trades just like its counterparts above. It’s a cooler, heater, dehumidifier, and a fan all in one unit. The system boasts of a 14, 000 BTU cooling capacity which offers year-round cooling in a room of up to 550 sq. ft.

The integrated heat pump, on the other hand, can deliver 12,000 BTUs of heating capacity, so they are both powerful and can work well in small, medium-sized, and fairly large rooms.  Plus, the fan is quite powerful and will circulate the air efficiently for a uniform result.

The unit has a good capacity dehumidifier that’s capable of pulling around 79.2 pints of moisture out of the air per day which puts it on par with most top units out there.

The best part is that it uses an auto-evaporation system to dispose of any excess condensation and you can set it up for either manual or automatic drainage.

Operating this Honeywell portable AC/heater combo is hassle-free. All four functions can be controlled through the digital LED display. It even includes an automatic programmable timer, so you can set the time when you want the system to turn off or on.

Like the other two models above, you can operate all the functions of this unit from a distance using a remote control.

The remote has a nice LED display too which shows the fan speed, current mode, and current room temperature. The touch buttons on the unit control panel are backlit, so they are easy to see in the dark and turn off after one minute.

The unit is relatively light, weighing around 73.85 pounds and has four caster wheels. You won’t break a sweat moving it from one room to another, but it might not be easy to carry it up and down the stairs. There are no side handles, so lifting it won’t be that easy.

When it comes to noise, the unit operates quietly for the most part, except when transitioning between cooling on and off. These two are the only flaws in an otherwise excellent overall design.

Bottom Line

As a four-in-one unit, the Honeywell MM14CHCS can serve you all year round with very minimal issues. Apart from the missing side handles and one-time noises, it’s a well-built and effective unit that we would highly recommend.

6. Friedrich PH14B

Friedrich ZoneAire PH14B Portable 4-In-One Air Conditioner/Heater/Dehumidifier/Fan with Reverse Cycle Heat Pump | 13,500 BTU, 115 Volt


  • Easy to set up, operate, and maintain
  • Comes with a fully washable air filter
  • Very effective cooler and heater combo
  • High capacity dehumidifier with self-evaporative system
  • Dual-hose system ensures a quicker and more efficient cooling
  • Automatically shuts off when the back-up reservoir is filled


  • Might require two people to lift it
  • Falls on the higher end of the price range

Taking the next spot is the Friedrich PH14B, one of the quietest, high-performing, upscale models featuring a dual-hose system. This is a great option for anyone looking to spend a little cash for quality and high efficiency.

Having an impressive 13,500 BTU AC, this Friedrich unit will comfortably cool down areas of around 500 sq. ft. Friedrich claims that the unit can cover up to 700 sq. ft. but that’s a bit farfetched as it won’t be that effective in such a large area.

However, you can be guaranteed that it will be highly-effective in small to medium rooms that are not more than 500 sq. ft. One thing that makes this possible is the dual-hose system which facilitates closed-loop cooling, delivering much quicker and more efficient results.

The heating function has a capacity of 10,500 BTUs, which is not as high as the other models but it’s nearly as powerful and will manage to keep you warm during winter when it gets cold.

You can adjust the temperature from as low as 60°F on up to 90°F at the top end. The unit also doubles as a humidifier. In fact, it’s one of the most effective humidifiers on our list aside from the Whynter ARC-14SH.

It can whisk away 101 pints of moisture per day which is a very high capacity and one that will keep the humidity levels in your room well balanced at all times. There is no water bucket to empty. The self-evaporative system does well to get rid of any excess moisture. Should water accumulate, the model has a built-in back-up reservoir to hold the excess moisture and is designed to automatically shut off in case the tank gets full.

The ARC-14SH won’t present any challenge when it comes to operating it. Like all the other units we’ve reviewed, it has an easy-to-use control panel with an LED display. It features a 24-hour programmable timer as well.

Another nice addition is the auto restart function. It automatically restarts the motor after a power outage or a power failure and the unit resumes operation according to the last programmed setting.

The only drawback is its hefty weight. The whole unit weighs 95 pounds which makes it the heaviest portable AC/heater combo on our list. It might require at least two people to lift it up.

However, it shouldn’t be hard to push around between rooms thanks to the smooth caster wheels and its easy grip handles. As I mentioned earlier, the Friedrich PH14B operates very quietly, at around 51 dB on highest settings, so noise won’t be a problem.

Installation is easy and quick. Everything you might need to install it is already included in the package, so the only thing you will find bothersome is its hefty weight.

Bottom Line

The Friedrich PH14B is certainly not cheap, but when you consider its performance, build quality, and design, it actually offers great value for money. If you have an extra money to spare, it’s definitely worth buying.

Despite its competitive price, the quality of this combo is very commendable. It’s a 4-in-1 unit like the rest of the other models on our list, allowing you to cool, heat, dehumidify, and circulate air using just one appliance. It’s a unit you can use all year round.

The 14,000 BTU cooling capacity is strong enough to efficiently keep a room of up to 525 sq. ft. in size cool and comfortable. Besides that, the unit is equally efficient as a heater. Its 14,000 BTU heating capacity is sufficient to keep a fairly decent-sized room warm during cold months.

The adjustable thermostat has a range of 64°F to 90°F, so you can set the temperature that suits your personal needs. It also does fairly well as a dehumidifier as it capable of removing up to 71.04 pints of moisture a day.

It doesn’t require regular manual draining since it also features an automatic evaporation system. There is also a carbon filter that cleans the air around the room and it goes for all year round.

Operating the AC-14100H is a piece of cake like all the other models on our list. It uses electronic controls and KCD display, plus you can also operate it using a remote control.

It includes a programmable and reliable timer that allows you to customize the operation according to your schedule. The system will cycle on and off based on how you’ve programmed it.

The unit is compact and weighs 62.95 pounds, hence it’s not so heavy and like the rest, it has four caster wheels that roll easily. You can move it around without much effort.

The noise level is acceptable, ranging around 45 to 57 dB on high settings which is fairly quiet to allow you to rest peacefully and comfortably.

Setup is not difficult either. The exhaust hose hooks up to the window vent easily and in just a few minutes. It’s a simple installation.

Bottom Line

The NewAir AC-14100H is a great product for anyone on a budget but wants a really good, versatile machine for both cooling and heating. It’s a quality unit that will perform well and last a long time.

Benefits of Investing in a Great Portable AC/Heater Combo

Setting up a separate air conditioner and heater requires a lot of space. However, portable AC/heater combos are small in size and occupy less space. They are ideal for areas with limited space such as a studio or small apartment.

Can Cool or Heat the Room

A portable AC/heater combo kills two birds with one stone. It’s an air conditioner and a heater at the same time. You can make your living area both cool and warm whenever you want. It gives you the same comfort you will get if you install the units separately.

How Does a Portable AC Heater Combo Work? 

A portable AC combo can heat or cool an area, depending on the setting that you select. On the one side, the compressor has coils that cool the air and create condensation. On the other, the heat pump heats it and releases the warm vapor into the room.

There’s an expansion valve that plays a significant role in how these two functions perform. When you turn on the cooling mode, the valve lets the refrigerant flow over the condenser coils. Alternatively, it reverses the flow to the heat pump, where the liquid is evaporated for warm air.

People Also Ask  

Below are some common questions surrounding this topic.

Can a Portable Air Conditioner Combo Be Used Without a Window?

Yes, it can. Many portable AC combos have trays to collect the condensation that you’ll need to empty on a regular basis. If you have a hose for venting, you can install it through the wall, ceiling, or door. You don’t specifically need a window for the device unless the manufacturer indicates it.

What’s the Average Lifespan of Portable AC Combos?

Even if you regularly use the air conditioners, you can easily get about five to ten years out of it. Some have shown an extra five years, but it depends on how well you look after it. If you maintain and service it at the correct times, it will keep you longer.

Are Portable AC Heater Combos More Energy Efficient?

This factor depends on the Energy Efficiency Rating. If you buy one with an EER of 11 or 12, you’ll have massive savings on electricity compared to a standard heater. You could see a cut of $100 per year in your utility bill if you purchase the right one.

How Large of a Space Can a Portable AC Combo Heat and Cool?

You’ll have to look at the BTU measurements. The larger the number, the greater the area it can cover. An 8,000 can heat or cool up to 250 sq. ft., while a 12,000 BTU can reach up to 450 sq. ft. if the room’s design allows it. Always measure the space before you buy a new portable AC combo.

How Many BTUs Should an AC and Heater Unit Have?

Whynter ARC-148MHP

To cool your room properly you need a unit that has an adequate number of BTUs based on your room size. For smaller rooms that range from 55 to 550 sq. ft., you should consider units with capacity ranging from 5,000 to 14,000BTU.

Note: Higher BTUs does not necessarily mean better cooling since an excessive number makes the unit work harder and may lead to premature malfunctions. Ensure that you measure your room well so that you can pick a unit with the appropriate BTU capacity.

Do Portable AC and Heater Units Use a Lot of Electricity?

Portable AC/heater combos are generally designed to be energy efficient and as such, they don’t have a significant impact on your electricity cost especially compared to a central cooling system.

Even better, some units like all the models on our list feature a programmable thermostat and auto turn off functions that help lower energy use. Therefore, they are not likely to sky-rocket your electricity bills any more than when you install the units separately.

Are Portable AC and Heater Units Loud?

When it comes to the noise level, it will majorly depend on the model you choose. However, most portable AC/heater combos are relatively quiet. The decibels of sound they produce mostly range from 50 to 80dB.

If you are a light sleeper or are sound-sensitive, then you would want to consider a unit that has a maximum noise level of no more than 60 dB on the highest settings.

There are also some models that feature a sleep mode whereby the fan runs at a lower speed, thereby reducing the noise it makes. For sound-sensitive people or light sleepers, this is another great feature you should consider when picking your portable AC/heater combo.

Find more info about me and HVAC Training 101.
