Hi I'm a newbie to this site.
I need a new system for my 1500sf rancher with no basement. I received some estimates and it was either a Carrier comfort 80 gas furnace with a performance series 13 seer puron versus the
Trane XR80 furnace with the XR12 13 seer ac. The trane has r-22. both have similar warranties and similar pricing.

Thanks in advance
