Currently we have a 19 SEER 2-ton Lennox just over a year old, and an 11.5 SEER 1.5 ton Lennox approx 16 years old.
The 11.5 works but our thoughts are to proactively upgrade that one soon.
The units I've explored/narrowed the choice down to are (1) a Carrier 13 SEER 8 HSPF, with an air handler that I'm told will bump the efficiency to 15 SEER, or a (2) a RHEEM 15.5 SEER & 9.5 HSPF.
My questions to the wise & veteran knowledges near & far are:
I've had a few people try to advise against a RHEEM unit. Is there a reason to steer away from RHEEM? Their HSPF of 9.5 seems pretty solid. The Carrier is an 8 HSPF. Warranties look identical.
Does the 13 SEER & strategically matched Air Handler, supposedly resulting in a 15 SEER performance, really do so and thus come close to matching the 15.5 SEER RHEEM?
The 9.5 HSPF seems so much better than an 8. Is that my major performance decision point? I'm in Western Virginia where we *DO* have a few months of nasty winter.
Any other wisdom, tips, thoughts, advice, etc. *ARE* greatly appreciated!!!
I'm just a homeowner who wants to tap as much synergy, and learn something to make my choice a better one.
In advance many thanks!
