Ahead, an HVAC expert answers all your burning questions about purchasing a portable air conditioner (and a few q's you probably didn't even think of).
Are portable air conditioners as good as window units?
It depends on the space you’re trying to cool. "Portable and window air conditioners are best at different areas," explains Craig Anderson, HVAC expert at Appliance Analysts, a site that provides detailed guides and reviews on all things home tech. "Generally, a window air conditioner is quieter, more efficient, and can cover a larger area than a portable air conditioner. However, portable models have a big advantage in how mobile they are," Anderson adds. For example, someone living in an apartment can move a portable AC between rooms. (Plus, it’s cheaper!)
Do portable ACs have to be vented out a window?
TL;DR: Yes. Portable ACs need to be vented out a window just like a normal air conditioner system. "Any air conditioner exhausts just as much heat as it does cool air," Anderson says, which means that, yep, even portable ACs need to be vented. "Note that you should make sure your window is compatible with the air conditioner's vent setup, he adds. "There are also other DIY options if you don’t have a window available, like venting out of a slider door, or into a different room." Noted!
How can I find the right portable AC unit for me?
There are *so* many portable air conditioners out there, so it can definitely be tough to decide which is right for your needs. Here are a few things to keep in mind while you shop, says Anderson.
- Estimate your required capacity. The larger the area you need to cool, the more power—which is measured by the metric of British thermal units (BTUs)—you’ll need. If your room is often in direct sunlight, is busy with roommates and/or pets, has high ceilings, or is poorly ventilated, you’ll definitely need more power.
- Make sure the exhaust vent will fit into your window. Most windows are fine, but casement or extra wide windows may require special installation kits.
- Consider functionality. Modern units will offer features like programmable schedules, mobile apps, thermostats, and energy-saving options. (All for a higher price, though, which can be worth it!) It just depends on how much you want your portable AC to do for you, exactly.
