Buying a portable air conditioner: A Buyer’s Guide

To begin, measure your available floor area. When it comes to air conditioner cooling capacity, British Thermal Units (BTUs) are often used. The more BTUs an air conditioner has, the better it is at keeping your space cool.

According to McKeon, an air conditioner requires an average of 20 BTUs per square foot of room to function properly. 

Therefore, it’s important to choose a unit that works well in your home, but don’t assume that more BTU output automatically means a better unit.

You may use the criteria provided by EnergyStar, a government program that promotes energy-efficient goods, to assist you in making your selection. The weight and size of a model often grow in tandem with an increase in BTU capacity.

  • 5,000 to 6,000 BTUs for cooling a room up to 250 square feet
  • 7,000 to 8,000 BTUs from 250 to 350 square feet
  • 9,000 to 10,000 BTUs from 350 to 450 square feet
  • 12,000 BTUs go from 450 to 550 square feet.

It’s possible that an undersized air conditioner will not be able to keep up with cooling demands on hot days, which will increase your energy costs because it’s working extra hard to keep up, according to Marla Mock, VP of Operations at HVAC services company Aire Serv, who previously spoke to NBC News Shopping.

To avoid early breakdowns and short-cycling behavior, don’t buy an excessive air conditioner. It will achieve the desired temperature too fast.

McKeon suggested the following things to look for while looking for a portable air conditioner.

Depending on the size and number of features, portable air conditioners may cost anywhere from $250 to $500.

Models with a single hose, which are the most prevalent, use a fan to circulate and cool stale air from your room. However, dual-hose systems are more expensive since they bring in fresh air from the outside.

Some smart portable air conditioners come with smartphone control and smart technology, but these versions are also more expensive.

For example, some come with a dehumidifier, heater, or even an air purifier built-in.

A timer that turns the unit on and off at certain periods might help you save money on energy costs.

Almost all units are self-evaporating; thus, they don’t need to be drained as often.

Remember that a window and an electrical outlet are both required for the proper operation of your portable air conditioner. 

It’s also important to remember to empty the unit when it’s full and replace the air filters regularly. That way, mold won’t be able to form in your unit and pollute your room’s air, according to McKeon.
