I thank everyone that has responded for the great questions and information.
The old system was installed when I had the house built 7 years ago. It was
a contractor's Carrier "lemon" as far as I am concerned and had a SEER
rating of 10 and an Air Handler brand with which no one is familiar. I plan
to have a Goodman installed that has a SEER rating of 14. The installation
company has been in business for 25 years. They fully expect the system to
easily exceed the 30% that they guarantee.

Thanks again to everyone for your help,
Bill

Something doesnt sound right. What if it is a hot year, what if with
with the new system you run it longer and cooler to get the utilities
way up. How does he know you wont open your windows to get your rebate
and upgrade.

He should be checked out with allot of refrences and Court records to
see if anyone has brought suit. How long has he been in business, under
Any name.

How old is your unit, what seer, did it cool good, to much or to
little. Did a load calculation get done.

What is your new unit and seer.

You could easily crank the unit and open windows to not get an 30%
savings, How will he know, then what does he do?

If you are getting a very high seer unit and your old unit has a very
low seer savings could be
50 - 75 % not 30 %
