Help! AC down Decision needed tonight
Brand new to the board. Hope y'all can help. I live in Texas Hill Country. Already had 15 straight days of record breaking heat (99) looking for 100+ in July in August. 22 yr old Lennox heat pump finally died. My wonderful AC guy has worked on it twice this week, gets it running and then it goes again. He's now looking for a used fan motor in his shop (just got new one over a year ago) to help me out until I can get new unit installed. He installs American Standard and Bryant, but prefers AS. Just gave me brochures as he left. Now the ?s: How big? I've got 1200 sq. ft 8 ft ceilings downstairs. (upper unit working fine, cross fingers) Can go 2.5 or 3 ton. Any suggestions? Probably looking at "Premium line" on both heat pump and indoor unit. Very confused though. Too many options. A couple of them in the lines still use R-410A which I thought was being phased out. Is the "Ultimate" line better enough to justify cost difference? Thanks so much for your help.
