This standardized technique was created by the ACCA (Air Conditioning Contractors of America) to help technicians figure out the right HVAC load for your home. The technician will need to take into account items like the height and area of your space, the number of windows and exterior doors, the number of occupants, and many other factors.
Whether you’re in the market for a new AC unit, heat pump, or furnace, make sure the HVAC companies you get quotes from perform a Manual J load calculation. It’s a precise way to ensure your new HVAC system is properly sized for your home.
Many existing HVAC systems are oversized for the home they are in because the previous installer cut corners when determining the heating and cooling capacity needed. An oversized system can waste energy and decrease comfort. For example, an oversized AC unit may cool your home very quickly, but not dehumidify it properly, leading you to feel cold and clammy.
