What size AC unit do you need?
Updated: Sep 21, 2019
Just did a 3700 square foot house with only one HVAC system. Nice new Bryant heat pump.
It had a 4 ton unit, 48,000 BTU/hr equals 4 tons of ice melting heat removed from the house per day.
This is from DOE.
VA is in zone 3 so we need more than 5 tons, or two units equaling about 6 tons.
