Portland sits in the Pacific Northwest region, where heavy rainfall and moisture-related building requirements (especially around roofing and drainage) are a bigger factor here than in drier climates. For home systems (HVAC, electrical, plumbing) projects like this one, that generally means equipment and code compliance usually drive the price more than labor hours, so ask contractors which brand/efficiency tier they're quoting.
