I had my whole heating and cooling system replaced by Climate Design in November 2007, at the same time that I was going through an extensive home remodel. At that time I dealt with many contractors, and I can say without a doubt, Jim from Climate Design was the best. He was on time, courteous, and very particular with his workmanship. He took the time to explain everything that he did, and has been very available for any questions that I have had since. The work and service are superb. Climate Design is highly recommended.
