Just performed a routine, maintenance and tuneup on a 36 year old train heat pump in the New Castle, Delaware area! This unit has seen better days for sure but it’s still kicking. after pointing out that the heat strips are not working due to both limit, switches being blown and lack of routine maintenance from previous owner has clogged up coil, both capacitors on the outdoor unit need to be replaced and the fact that this unit uses are 22 as a refrigerant lead to the discussion of a new unit install. We always give the client different options for repairs but logically it does not make sense to recommend them
