Sizing a Houston HVAC System | Best Pick Reports
Correctly sizing a gas furnace system, air conditioning system, or heat pump system is extremely important. If the system is too small, it will not adequately control the temperature of the house on especially cold or especially warm days. If the system is too large, it will cycle on and off frequently, creating excess noise, lower efficiency, and potentially decreased humidity control. Since operating inefficiencies occur as the system cycles on and off, additional cycles waste energy. Because the air conditioning and heating contractor selling the system also sizes it, it is vital to buy systems from reputable companies that will run an ACCA Manual J heat load calculation to determine the proper size of the unit.
