Blower door test and HVAC ducts
We had our house blower door tested recently. I didn’t think about it at the time however we have a geothermal heat pump. The geothermal HVAC unit sits inside the walkout garage and ductwork runs into the conditioned space of the home being tested.
During a blower door test, how significant would the leakage be if any from air being pulled through the cabinet of the geo unit? Do you normally seal of the ductwork at the unit for the blower test?
