Would anyone please tell me if there is any majoy difference in the following two A coils from American Standard.
I am having a 90 plus comfort R installed in my home.
The contractor originaly listed a "TXC031S3HPC" but showed up with a "TXC036C4HPC".
American Standards web sight shows one as a High efficiency universal heatpump/cooling. The one he is installing just says universal heatpump/cooling.
The contractor says no major differences.
Would like your opppinion on this.
Second question. He has brought over a White Rodgers model # 1F85-275, 80 series standard thermostat.
Any oppinions on this item, good or bad.
Also oppinions on best way to hook this up for maxumium comfort and efficiancy.
