Asked our local contractor to give us an estimate on an HRV install. The house is new construction and (when we close) it will have two 8" insulated flexi ducts to serve as the fresh air intake and stale air exhaust. There are two 90 degree bends, one fairly sharp, the other much less so. Unfortunately, the total run of each is about 50-60 feet. Going straight through the utility room wall to the outside is not an option.
House is a ranch with a finished basement. 3900 sq ft total, 4 br, 3.5 ba. In dry Colorado.
Is this going to work, or is there too much resistance to flow with the long lengths?
Any recommendations on a unit that would do better with these long runs. A Broan HEPA ERV is their default unit.
Thank you very much!
