I have a question for those of you who may have had experience installing one of these type systems.
A customer of mine wants a hybrid system, heat pump (410A - 14 SEER)/gas furnace (90+%AFUE) combination.
Is there a favorite brand that's preferable? Would the gas furnace be rigged to be second stage heat? Could it be set up with an outdoor thermostat that would give the furnace signal to come on at 35 deg F (or some determined temp) or below?
He also mentioned he'd like to have the option to use backup heaters in the heat pump as an alternative to gas depending on future gas prices. I'm not sure how to do this but it can be done I'd like to find out how.
Experience installer but not for one of these systems. Any input or advice appreciated.
