Warren was very professional, conscientious, and methodical when checking and performing the maintenance testing of our home heating system. Additionaly, he discussed and recommended steps for my wife and I to take in order to better maintain our overall heating and a/c system. Going through his check list and testing, Warren recommended that a part needed to replaced because of wear and age. Warren assured us that Belair Engineering would be contacting us to set up an appointment for the replacement part.
