I had hoped that my current system would last one more summer, but it didn't. 26 years old, 4 ton, 10 SEER. 3600 SF house with 1600 of the SF in the Basement
I am looking at replacement heat pumps.
One is a Goodman 4 ton, 16 SEER, 9.5 HSPF, Single Stage, Heat pump
the other is:
Amana 4 ton, 16 SEER, 9.5 HSPF, 2-Stage, Heat pump
is the 2-Stage worth the extra $700? everything seems to be the same except the single stage vs the 2-Stage.
