Im in the process of building a new house
2 story 2500 sq ft.
We are using spray foam insulation and it is set up with a 2 heat pumps and 2 back up furnace one for upstairs one for down stairs. With that being said the house is going to be real tight and need a source of fresh air. With that being said. Will an HRV with a capacity of 3000 sq ft home work if I only have it hooked up to the downstairs system. Thanks for the replies.
