new ac in the Tucson desert
We need to replace our 18 y.o. AC system and have bids from 2 companies that do comparable service but gave us very different bids. One bid looked more professional, but the other came from a co. we've had good service and a contract for years. Any advice would be great!
The house is 2000 sq ft with lots of windows and 3 levels. The top level has a separate system. The difference in the two bids is that our current co. proposes 2 RHEEM gaspack models: RRPLB042 - 3 1/2 tons and RRPLB024- 2 tons, both with 14SEER and will give us a year free service contract, for $12K.
The new company proposes (2) American Standard 4YCY0, 14.25 SEER at $19,800;
Am. Standard 4YCZ0, 16.4 SEER at $19,800 or
Lennox 15GCSX, 15 SEER at $16,750. The tonnage isn't specified and they also recommend using Aeroseal to seal the ducts, at an additional cost.
I read that the EER measure is important in our climate, but can't find that listed anywhere and wonder if that is applicable for the packaged units.
We know next to nothing about how to choose, except that we like the lower cost, of course! Thoughts? thanks so much.
