Keeping the Temperature Right for You Since 1962

Summer is right around the corner in Harrisburg, North Carolina, and you’ll want to make sure your air conditioner is up to speed before the hottest days of the year arrive. The size of your air conditioner is key to keeping your family cool on a budget, as systems that are the wrong size tend to waste energy and drive up your electricity bills.

Suspect that your cooling system is too large or too small? Follow these three steps to determine if your air conditioner is the right size.

Do the Math

Determining the optimal size for your home’s air conditioner is relatively easy if you have a calculator handy. Take your home’s square footage, multiply it by 30, divide that by 12,000, and subtract one from the result. You should end up with a number between one and five, which gives you a rough estimate of how many tons of capacity your home’s air conditioner should have.

Look on the Label

Next, go to the outdoor unit and look for the label. You should be able to find the model number, or M/N, which typically includes a string of digits and letters separated by dashes. The first group of characters reflects the system’s efficiency, but the second group of digits indicates the system’s capacity in British thermal units (BTUs). Simply divide the number by 12 to determine how many tons of capacity your air conditioner has.
