First post here. Looks like some interesting reading.
How would I find out what the SEER rating in my old heat pump is?
I have a 2.5 ton York heat pump. Approx 14 years old. Model # B3PS030A06A, serial # NKAM151183 It's been falling apart during the past year. The compressor still works great, but everything else is failing due to age. Leaks, Accumulator rusted through, control board, etc.
I'm having it replaced with a larger 3 ton Rheem RQPL series 14 SEER with 410A refrigerant.
I would like to know the SEER rating of the old unit and how much (ballpark) can I expect to save with the new one? 10%, 40% How much?
