We live in the Pacific Northwest, own a 4,000sf home that was built in 1908 and was taken down to the studs. We're in the process of remodeling and have elected to go for the Trane XL20i heat pump AND the XC95m furnace. Since we're going for a 4 Star built Green certification and an Energy Star Northwest certification we have to have the house sealed up quite tight. The goal is 4.2 ACH50. It can get quite windy in this location and we have our share of damp days between Sept and May!
Would you recommend we add the Trane Fresh Effects ERV or another unit (my understanding is the this would integrate more effectively with the communication components of the other Trane products, also looked at a Honeywell?
Thanks for any guidance.
