Let's say I have a 31/2 ton plus a 5 ton split carrier. (2) systems, about 9 years old. I would guess the SEER rating to be maybe 11-12? I want a quote on changing them out to 16 SEER. I want Sears Home Improvement to do the job. it's gonna be EXPENSIVE.
Sears is a good company, but how can I justify going to an Infinity for the amount of energy saving Vs cost? Is there more than meets the eye? (not for using Sears but for doing the change-out) The current unit works.
Load me up with reasons to do this.
