We purchased our house approximately 2 years ago. The furnace and air conditioner are Train branded and were originally installed by Colbert Heating & Cooling. We initially contacted the company as the blower had failed and needed replaced. Joe arrived on time, determined the failed part, and ordered it the same day. A couple days later when the part arrived he was back and had our system working again perfectly. I greatly appreciated his advise regarding regular maintenance and which type of filter to use. Everyone at the company is professional, knowledgeable, & friendly. We've used them for all our furnace and air conditioning maintenance ever since.
