HVAC Load

HVAC Load sizes heating and cooling systems for US houses. Enter floor area, ZIP code and year built to get heating and cooling BTU/h and tons. See where the load comes from, get CFM and a duct size per room, and check if the unit you plan to quote fits. For a heat pump, see the balance point and backup heat. Make a two page PDF report with your logo. The web app is free, needs no account and works with no signal after the first visit. Estimates in the style of ACCA Manual J, not affiliated with ACCA.
