We've been using ClimateMagic for 20 years now....hard to believe....excellent company...from the first phone call from Michelle, with a reminder of our 6-month "check -up", or assisting us when we have a problem...she is friendly and helpful.....to Martin, who we always request.....he is dependable, prompt, friendly, very experienced and knowledgeable and we consider him a friend after all these years....and, of course, David, who obviously provides a positive work environment for everyone....great company!!!
