I had a company come in today that sells Arzel zoning equipment. They said to zone the 1st floor and basement they would insert dampers into each supply currently to the 1st floor. To service the basement they would tap the main trunk and have to split one supply to the first floor. They would add one return to the basement
Is this the way its done?
Do they know there is going to be enough air flow to properly service the area?
Just really need the zoning for heat as the basement is cool in the summer
