Dear Dave/Cliff

Hi Dave and Cliff,

I wanted to let you know how pleased I am with my insulation. The guys that did the installation did a great job, they were very professional, courteous, got the job done quickly and cleaned everything up when they were done.

I noticed a difference the first day, I didn’t have to turn on the air and the house stayed a consistent cool temperature, no fluctuations, even in the morning it was warmer in the house than it normally is, who knew insulation was so important. Thanks for doing a great job!

Dear Dave

I am very happy that I participated in this program. I was able to get back $4000 and the check showed up quick. Your guys did a great job on the retrofits and I will be referring you to my friends. Thank you !!

I really like the fact that you handled everything from start to finish. My rebate check showed up quick exactly as you had said it would. I would reccomend this program to anyone looking to upgrade thier home. Thank you Cobalt !!!
