"One of the larger HVAC companies in Chicago told me I needed a new boiler to the tune of $8000, but something smelled fishy to me. On a referral from a friend, I called TDH, and their technician came out and checked out my boiler and told me there was nothing wrong with it. He also told me that the other company pays their technicians COMMISSION on anything they sell, producing a huge conflict of interest. TDH did some minor maintenance on my boiler for a low/reasonable rate and saved me close to $8000. Thanks TDH!"
