What Size Air Conditioner Do I Need For My House?

If you already have central air conditioning and have not modified your home since it was installed, it is almost always sized properly to your home. If the size of your home has changed through an addition or other renovations, or you have made enhancements that affect air flow (such as window or door replacements or changes to your insulation), it may be time to have a professional perform a new Heat Load Calculation on your home to assess the proper size air conditioner and heater you will need. If you are installing central air for the first time in your home, you will need a Heat Load Calculation to identify the size.
