My brother's church is considering replacing the 25 year old air handler, Ruud model uhqa 1220 t. The heat pump is an Arcoaire, model yj036gb1 only 9 years old. It's a mismatched system that requires the service tech to add r22 for the cooling season and take it back out for heating season.
I know the local Arcoaire distributor in this area so I called him up to ask him if he could get an air handler to match the existing heat pump. He quoted me a price on a fsm3600. He told me that this was a 13 seer unit, but that would not be a problem mating it with the 10 seer heat pump.
I have my doubts.
Any input for you all would be appreciated. I don't want to see the church install another incompatible system.
