Looking for stats on “old” unit – Help


I have a Inter-City Products YE036G heat pump manufactured 9/1993 and a GrandAire GB3BM-036K-A-10B air handler. I am assuming because of the reference to “36” in both units that these are 3-ton products, but does anyone know about what SEER they are? I am looking for replacements and would like to compare the current efficiency rating.

Thanks for the help!
Jason

1993 would most likley be 9 seer at best. Todays minimum which soon will be extinct as well is 13 seer.

14 minimum as of two years from now.

WOW, that was a super fast response. Thank you.

Potentially stupid question…
Why would a new unit with the same capacity, but more efficient (13 SEER) instead of whatever the current one is require a higher current breaker? (Going from a 30-amp to 40 or 45-amp on the condensing unit.) I have been quoted a PH13NA063000 heat pump and a PF4MNB037T00 air handler both are 3-ton, 13 SEER Payne products.

They are probably going by the Max circuit protection rating. The original installer may have used the min.

I hear you.

Our Seer rating stays the same but we have to start using 90% furnaces, no more 80%

Crazy thing is every wholesaler is saying it won't happen in Mi.

Go figure.
