That combo would be fine.

13.00 SEER
8.20 HSPF
34,600 BTU cooling
33,400 BTU heating

I'd probably get a Rheem myself

RGRA-09 furnace
RPNL-036 pump
RCFL-HM3621 coil

13.00 SEER
8.45 HSPF, a bit higher than Trane
38,000 BTU cooling
39,000 BTU heating, or 1/2 ton more heat than Trane - means warmer air and less backup needed.

Bill:

For a heat pump, especially with expensive propane back-up, you need the following:

- 14 to 15 SEER
- 9 HSPF (Heating efficiency).
- 12 EER (Cooling efficiency on hot days).
- Full 36,000 heating/cooling btu's (you need all 3 tons).

Mfr doesn't matter much as long as these performance numbers are met.

A good installation is critical.

Good luck.

I agree with Gary. Unfortunately it seems hard to get 9 HSPF out of many top manufacturers on their more basic systems, however.
