Having HVAC put into my 1926 Spanish-style home. 1 story house, 1160sf, no duct work currently, radiant floor furnace. I'm in Los Angeles and the house isn't that well insulated but does have dual-pane windows. All estimates were for a 3 ton unit - every installer has agreed on that point, at least...
I've gotten two installers recommending Amana 14 SEER with a 95% furnace (ASX14 with AMH95). A third recommendation was for Carrier and was quite a bit higher overall and SEER rating was 15 or 16. The fourth recommended a 16 SEER Ruud with an 80% efficiency furnace and his price was right in line with the Amana guys. (Mr. Ruud says he would stay away from Amana as they are the Hyundai of the HVAC market.)
So, my questions are - What's the verdict on these Amana units? Are they as good as Trane and Carrier? Are they considered low-end or are they comparable to the others?
Thanks for reading!
