Both are 5 Ton, single stage, R410A. This install is using my current duct, A-coil will be installed in the plenum above the Current Lennox G21 Pulse, which will act as the heat strip. The quotes, parts, and labor warranty are the same for all intents and purposed. Both installers are equally qualified. Pretty sure both have Copeland scroll compressors. I am primarily concerned with the heating capibility. Cooling is just gravy, but I'm sure we'll enjoy it. Here is my decision:
Payne (PH3A) is rated 13 SEER 7.7 HSPF
Goodman (GSZ13) is rated 13 SEER 8.4 HSPF
I'm thinking the Goodman because of the higher HSPF. The guy that is selling Payne says the Goodman will only equal 7.7 HSPF because of the way it is installed into the plenum above the lennox pulse. He says if it was not a split system, I might get 8.4 HSPF, but as it stands, I won't.
Does he speak the truth? Would this mean his Payne will only equal 7.0 HSPF with a plenum install? Just trying to make the best decision.
