Frequently asked questions
There are hundreds of air conditioner models to choose from, so if you’re trying to figure out where to start, we answer a few of the most common questions shoppers ask.
What size air conditioner do I need?
Air conditioners’ cooling capacity is measured in BTUs, with higher BTU ratings indicating a more powerful unit. If you have a large room, more than 300 square feet, look for higher BTU ratings, while smaller rooms can handle lower capacity air conditioners. Most ACs state the size of room they work in.
How many BTUs do I need?
The BTUs you require largely depend on the space you’re working with. The general rule is that larger spaces require an AC with higher BTUs. For a more exact answer, you can use this BTU chart that explains what you need based on your home or room’s square footage.
Are there energy-efficient air conditioners?
Yes, there are definitely energy-efficient air conditioner models. Many ACs also have eco-modes that shut the AC off and on when you’re not home, when you’re sleeping or when it gets cold enough in the room.
How long will my air conditioner last?
With proper maintenance, most air conditioners can last for years. Make sure to take window units out and store them in dry places. Covers or keeping the original boxes to store your ACs in can help components stay clean and safe.
