When sizing a heating and cooling system for a home, rule of thumb measurements can yield an improperly sized system. Yes, you've probably heard it all before, but a poorly sized HVAC system can lead to an uncomfortable living environment and higher bills for the homeowner, to name a few. The popular method of calculating heating and cooling loads is to use ACCA, Manual J-compliant load calculation software. The old method of buying a Manual J book and sizing by hand is rarely used these days due to all the great software available.
The most common problem in the HVAC industry is the tendency to oversize equipment. Contractors and customers alike are conditioned to believe bigger is better. Unfortunately, bigger leads to higher installation cost, higher operating cost and a more humid house. Yes, an over sized system will not run long enough to remove moisture from the house, and in turn, the customer will feel clammy due to a higher humidity level in the house. The customer in search of greater comfort will now lower the thermostat to feel more comfortable and will keep lowering it until the unit runs enough to remove moisture.
