Climate Magic came out and checked my duct work, it was built with the house. Right away the technician spotted the problems of not enough air flow, and suggested the duct work be changed for better efficiency. They came out new what they were doing, were professional and handled my home with care, just little things like shoe booties. And when they were done, I could really feel the difference in air flow and in the electricity bill. I would highly recommend them to any one.
