The 10 Best Portable Air Conditioner With Heater Combos

What is the best portable air conditioner with heater?

Maybe you don’t have central heating or air conditioning at work or home. Or even if you do, you’ve probably felt the need for adjustments for hot spots, for example. Or do the bills get too high, and you don’t need to cool or heat all the rooms all the time?

The answer to your problems is an air conditioning unit. While the stationary air conditioners are lovely and powerful helpers, the portable air conditioners are the real deal: convenient, versatile, small, and multifunctional.

Can a portable air conditioner be used as a heater?

While the portable air conditioner and heater combo is most often used for cooling, it may be a very convenient appliance during the cold weather too. Sometimes it even covers a bigger area for heating than for cooling. The machine’s heating mode also has much more energy efficiency than its conventional counterparts.

Besides, the portable air conditioners have many advantages over the standard heaters and all stationary AC. They are easy to move and maintain, have much lower energy consumption, and take less floor space.

What to look for in the best portable air conditioner and heater?

When considering an order for the best portable air conditioner and heater combo, it’s essential to take into consideration the room size and the overall space size and distribution. For small rooms/places of up to 200 sq.ft a unit with 8000 BTUs will be enough for both cooling and heating needs. For rooms up to 250-300 sq.ft products with 10000 or even 12000 BTUs will be a much better choice, and a 12000 BTUs may very well cool even a 400 sq.ft. Spacious spaces up to 500-600 sq.ft will need a 14000 BTUs. Noise level doesn’t depend on the BTU rating.

It is good to take in mind that all brands’ portable air conditioner units are not at their best when used for cooling (or heating) more than one room in a flat or connected office space. Narrow doors or twisted halls will hamper the airflow even further. The best choice is always to use one but smaller BTUs for all different separate areas, where available. In this case, the portable air conditioner and heater will provide the versatility and convenience needed. Your unit has excellent mobility and can be rolled on wheels wherever you need it in the current moment to avoid wasting your energy bill.

What are the BTUs?

The Air Conditioners’ power and efficiency are measured in BTU: British thermal units per hour. The bigger BTU is, the bigger spaces this air conditioner and heater can cool or heat.

For many of the portable air conditioners, you will see two different numbers provided: the ASHRAE BTU (which is the bigger one) and the DOE one (which is the smaller one). The ASHRAE index is a description of the optimal working power of the unit (in British thermal units [Btu] per hour). The DOE (Department of Energy) measures the Air Conditioner’s “real” airflow. Sometimes the DOE and ASHRAE indexes differ significantly.

 What is the EER?

The energy efficiency ratio (EER) measures the efficiency of the air conditioner unit. The EER is the ratio of the cooling capacity (in British thermal units [BTU] per hour) to the power input (in watts). The bigger the EER results are, the better performance the air conditioner unit gives. The EER is stated on the Energy Star label.

Operational noise level

Most portable air conditioner units work with an operational noise level around 56dBa or lower, which allows the users to sleep while the unit fans and compressors are working in the same room.

Which is better, a dual- or a single-hose model?

The portable air conditioner units use an exhaust hose to blow hot air outside the workspace. The single hose units suck that air from the room they operate in, which makes the working process slower. The dual hose units have an additional intake hose, and it allows to cool (or heat) the workspace quicker (by up to 40% in some cases). The downside is that the dual hose unit efficiency will be lower because of the intake of warmer, unconditioned air, and sometimes the energy usage may be higher. It’s not that big a difference, but if the operating speed is of importance, then the dual hose units are the better choice. If you aim for efficiency, the single hose one should be preferred.

Taking care of your unit

The time and effort spent on cleaning your portable air conditioner are an essential part of the unit’s consideration.

Almost all brands’ portable air conditioners have separate built-in dehumidifiers or draw moisture from the air while cooling. Some models have automatic drainage systems that blow out the moisture through the exhaust tube. Even so, periodic drainage needs should be taken into consideration, especially in high humidity climates.

Removable or washable filters or pre-filters are essential features, and an activated carbon filter should be considered too.

Other options to take into consideration for all the models, are the display setting (top or front), the remote control and timer, eventual Wi-Fi, Alexa, and smart home connectivity.
