I am so happy with my new air conditioning unit. My electric bill is $250 less than it was the same time last year. The zoning system dampers make it so that the upstairs is cool without freezing out the downstairs. The whole family loves it. Thank you so much. It is comforting to working with a company that is bonded and insured, has been around for a really long time and has an A+ rating with the Better Business Bureau (yes, I checked!).
