After calling a few companies, and getting their estimates, they were the second on my list. After my first choice was not able to do the job, I called back to Cool Air and their representatives, Phillip and Stephen came back to give me another offer, which I couldn't refused. Their warranty was a (5-10-10-20) and we decided to do the job. It was in middle afternoon, and by 6pm the new unit was installed and running. I couldn't ask for more. Great job by Phillip and Stephen and by the installers.
