What Size Air Conditioner is Right for Me?


Not all air conditioning systems are created equal. In fact, an air conditioning system that is too big or too small won’t be able to efficiently cool your home and can spike your energy bills. When it comes to cooling your residential or commercial space, you’ll need something custom to meet your unique needs. Learn about different air conditioning sizes and which is best for your space.

What Sizes Do Air Conditioners Come In?

Central air conditioning systems come in a variety of sizes. These sizes are measured in tons, but aren’t based on weight like you might be thinking. Instead, the term “ton†is used to measure an air conditioner’s ability to cool 12,000 British Thermal Units (BTUs for short) in a one hour timeframe. For example, a “3-ton†central air conditioning system will be able to cool 36,000 BTUs every hour.

The air conditioner in your home most likely ranges between one and five tons. While larger air conditioners exist, these will usually have multiple units in tandem, as well as zoning systems.

What If My Air Conditioner Is Too Big?

Some people assume that a bigger air conditioner will be able to provide more cooling power throughout a home. But contrary to popular belief, an oversized AC will do more harm than good. A large unit will likely cool your home very quickly and then promptly shut off. Since it won’t be completing a proper cycle, your home will get warmer faster and your AC will have to turn on again and repeat this cycle. While this may not seem so bad, an AC that cycles too often completely defeats the purpose of an AC’s energy efficient design.

What If My Air Conditioner Is Too Small?

The opposite end of the spectrum is having an air conditioner that is too small. An AC that is too small for your space will constantly be trying to keep up and cool your home. While it may eventually be able to cool your home, it won’t be able to do it efficiently, meaning you’ll be left with steep energy bills.
