I am in the process of replacing the AC and furnace in my house. I live in Nothern Virginia. The contractor I have contacted are pushing this type of unit, a hybrid heat pump (HP with a gas furnace back up for temp below 40 degrees). I have looked at carrier, Trane and Lennox. I would like to know if anybody has any experience with these units and their performance.
Also, all have indicated that I should go with a 80+ furnace because a higher efficiency unit, 90+, will require a new PVC exhaust. Does it make sense to go with this hybrid unit with a 80+ furnace?
Any advice will be welcome.
