I must place a review recommending this company for your heating & AC. In fact, I strongly recommend the main contract. Mary is very professional, kind, and patient! I had to call her a few days in a row due to a very stubborn heating problem. Keith is also professional, kind, and honest. He came to the house to fix it and did but when I arrived home; the heat wasn't working. This happened twice but Mary and Keith did not give in to the stubborn unit. Keith even found a large birds nest that seemed to be the cause but it was not. So, Keith came a third time within a week and thank God the 3rd time was a charm! He figured out the true cause! Thank goodness too for the Maintenance Contract as all these service calls didn't cost me an arm and a leg. Keith and Mary even called me the next day to followup and ensure everything was good! You can't go wrong with this company and most importantly they will take care of your problem! Thank you Mary & Keith!
