FAQs
Do portable air conditioners need to be vented?

Yes, since portable air conditioners extract heat from smaller areas, it's necessary to vent the hot air out to allow for cooler air circulation. Common venting methods include placing the unit near an open door or window and using a ventilation kit to direct the hot air outside or utilizing a venting hose to channel the air outside. For more information on ventilating, read our article about heat mitigation strategies.

How do portable air conditioners work?

Portable air conditioners use a fan to draw in the hot air from outside, which is then cooled by the condenser coils, refrigerant and compressor before being released back into the room. The remaining hot air and moisture can be vented outside to make room for proper ventilation and cool air. Need more help? Contact our equipment experts for further assistance.

How well do portable air conditioners work?

Portable AC units are effective at ventilating and dehumidifying small rooms and cooling off enclosed areas. Portable air conditioners are an efficient and mobile climate solution, serving as an alternative to central air conditioning. With built-in casters, these spot coolers can be used nearly anywhere they are needed to bring airflow.
