Wall-Mounted Air Conditioner Comparison Table

Specs and Performance

When you shop for a wall-mounted air conditioner, you want to know how well it works. You should look at the cooling capacity first. This number tells you how much space the unit can handle. For example, a 6,000 BTU wall-mounted air conditioner works best in a small bedroom. If you have a bigger space, like a living room, you might need a 12,000 or even 14,000 BTU model. The largest GE unit, with 14,000 BTUs, can cool up to 700 square feet if your home stays shaded and insulated.

You also want to check how much energy the unit uses. Most wall-mounted air conditioners today have high SEER ratings. That means they use less power to cool your home. For the best energy savings, try to get about 20 BTUs of cooling capacity for every square foot. If you live in a hot place, you might need 22 or 25 BTUs per square foot.

Here’s a quick look at how different models compare:
