HVAC registers & cold air return
We are building a new home and installing a heat pump and gas furnace in a 2550 sf home with the main living area upstairs and bedrooms downstairs. Our builder met with the HVAC contractor today and we are meeting with the builder tomorrow to go over the plan of where to place the registers, etc. The builder already told me he would place the cold air return in the upstairs ceiling of the main house.
I just want to go in prepared with questions. Our builder asked us to think about where we want the registers. But I've been noticing other talk about various cold air returns and our builder only mentioned the one. Is this normal?
Also, with the heat pump, should there be more than one thermostat in the house? It sounded like he was just putting in one...
Thanks for any help!
