In our guide today, we’ve also included some useful information about portable air conditioner and heater combos that might come in handy when making your decision.

Benefits of a Great Portable Air Conditioner and Heater Combo

A portable AC/heater combo comes with some amazing benefits which include:

Highly Portable

These units are compact and lightweight, making them extremely portable. Most of these units even come with wheels to make it all the more easier for you to move them from room to room without needing to struggle.

Space Saving

Having to set up a separate air conditioner and heater in a room will require a lot of space. However, a portable air conditioner and heater combo is small in size and hence occupies less space. They’re the ideal solution for areas with limited space such as a studio or a small apartment.


A portable air conditioner and heater has the ability to kill two birds with one stone since it’s an air conditioner and a heater combined in one convenient device. With just one piece of equipment, you can make your living area both cool and warm whenever you want. It gives you the same comfort as installing two separate HVAC units of air conditioner and heater.

Energy Efficiency

Portable air conditioner and heater combos use less energy than running two units separately. Therefore, investing in a portable AC/heater will help you save a decent amount of money in the long run in the form of electricity bills.

Easy Installation

These portable air conditioner and heater combos require almost no installation and no drilled holes. All you need to do with them is to place them right where you want them, fix the exhaust hose for draining and you’re all set.

Aspects to Consider when Shopping for the Best Portable Air Conditioner and Heater

Here are a few factors that you need to take into consideration to better pick out the right portable AC/Heater for your needs:

Cooling and Heating Capacity

All portable AC/Heater combos have their cooling and heating power measured in terms of BTU’s (British Thermal Unit). Each unit has a specific capacity and your choice will depend on the size of the space or room you plan on using the unit.

Hence, it is important for you to measure the size of your room before you decide on which model to purchase in order to correctly determine the right number of BTUs required to cover the space. A good rule of thumb to follow in terms of BTU required is as follows:

  • 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

Generally, the larger space your unit needs to cover, the higher the BTU required. A higher BTU rating also means that the system is capable of cooling or heating the room faster.

Energy Efficiency

Portable AC/Heater combos tend to utilize less energy to cool or warm their surroundings. Still, it is important for you to buy an energy-efficient model that has good performance to keep your utility expenses down. Therefore, it is important that you take the unit’s energy efficiency ratio (EER) into consideration.

The higher the EER rating, the better the energy efficiency of a unit. This simply means that a unit with an EER for ten would be twice as efficient at energy utilization as one with an EER rating of five.

Unit Weight and Size

The weight of a portable air conditioner and heater combo significantly determines how portable it really is. Most units often weigh on average 45 to 95 pounds. But if you’re planning on moving the unit up and down the stairs, you will want to consider a lighter model.

Having a compact unit that takes up less floor space is also ideal, especially if you have a limited amount of space in your small apartment. Therefore you should also consider the depth and width of the unit and look for something in the range of 12 to 18 inches.


An adjustable thermostat is a feature that comes in very handy as it lets you adjust the heater to your desired temperature. A unit with an additional feature of a thermostat gives you the advantage of being able to set customized settings compared to one without a built-in thermostat.

Dehumidifying Feature

Most portable AC and heater combos have an additional dehumidifying feature to help eliminate any dampness in the air, providing a healthy atmosphere and greater comfort. However, not all models have this function, so you should decide beforehand whether this is a must-have feature for your portable AC/heater or not.

Plus, the fan is also quite powerful and is able to circulate the air efficiently in a room for a uniform result.

The 14,000 BTU portable air conditioner is ideal for smaller to fairly large rooms that are not more than 550 sq. ft. The heater also has a capacity of 14,000 BTU meaning you can trust it to cope well in colder months.

This portable air conditioner/heater combo also comes with an adjustable digital thermostat with a range of 62°F to 88°F for you to set the exact temperature you want based on your desired comfort level. It also has a dehumidifying function that can extract 71 pints of moisture per day.

The self-evaporating function uses the moisture collected during air conditioning to cool the air down, meaning you don’t have to worry about moisture build-up inside the unit nor the need to manually drain the water tank as frequently.

6. Friedrich PH14B

Next on the list is the Friedrich PH14B. This portable air conditioner is one of the quietest yet high-performing, upscale models that come with a dual-hose system for ultra-efficient performance. This is a great option for those willing to spend a little cash more for quality and efficiency.

Boasting an impressive 13,500 BTU cooling capability, this Friedrich AC unit will be able to comfortably cool down areas of around 500 sq. ft. The AC and heater company also claims that the portable unit is able to cover up to 700 sq. ft. area, however, we feel that claim is a tad bit far-fetched and may not perform as effectively in such a large area.

However, you can still be guaranteed that it will deliver highly effective heating and cooling capabilities in small to medium rooms that are no larger than 500 sq. ft. One thing that makes this possible is thanks to its dual-hose system which facilitates closed-loop cooling to deliver quicker and more efficient cooling results.

As for the heating function, this AC and heater unit has a capacity of 10,500 BTUs. Though it’s not as high as the other AC and heater combos, it is nearly as powerful and will be able to keep you warm during winter when it gets cold.

This best portable AC unit also has a built-in thermostat that lets you adjust your desired temperature from as low as 60°F to 90°F. The unit also doubles as a dehumidifier. In fact, this is one of the most effective dehumidifiers on our list today and can whisk away 101 pints per day, which is a very high capacity and one that will definitely keep the humidity levels in your room well balanced at all times.

Another highlight is that this appliance does not require you to empty a water bucket thanks to its self-evaporative system that gets rid of any excess moisture all by itself. In case there’s water accumulation, the unit also has a built-in back-up reservoir to hold the excess moisture and is designed to automatically shut off once the tank gets full.

Operating the ARC-14SH won’t present any challenge thanks to its easy-to-use control panel and bright LED display. It also features a 24-hour programmable timer and an auto-restart function that will automatically restart the air conditioner motor after a power outage or power failure. The unit will also resume operating based on the last programmed setting before the power was cut.

The only drawback to this otherwise amazing portable air conditioner and heater combo is its hefty weight. The whole unit weighs about 95 pounds, making this the heaviest portable AC/heater combo on our list. It’s so heavy that we recommend at least two people to lift it up.

However, this unit isn’t hard to push around between rooms thanks to the smooth caster wheels and easy-grip handles. The Friedrich PH14B provides a very quiet operation, generating around 51 dB on the highest settings, so noise should never be a problem with this unit. Installation is also quick and easy. All you need to install it comes included in the package.

Bottom line, the Friedrich Ph14B is not the cheapest of the lot. However, if you do consider its performance, build quality, and design, it does offer great value for the money. This is definitely worth the investment if you have extra money to spare.


  1. Easy to set up, operate, and maintain
  2. Comes with a fully washable air filter for easy maintenance
  3. Effective cooler and heater combo
  4. High capacity built-in dehumidifier with self-evaporative system
  5. Dual-hose system for quicker and more efficient cooling
  6. Automatically shuts off when it detects the back-up reservoir is filled


  1. Might be too heavy and require two people to lift it
  2. Might be a bit too expensive for those on a budget
