What's the Difference Between an Energy Audit and an HVAC Load Calculation?
If you've ever installed new HVAC equipment, you've probably had your contractor perform a load calculation. You might hear your contractor refer to these estimates as a "Manual J" calculation, and they'll often use specialized software to perform them. While a Manual J can help you size your new HVAC equipment, it doesn't tell you everything about your home's energy needs. If you want more information, that's where a whole-home energy audit can come into play.
