after a lengthy period securing numerous estimates to replace my furnace and air conditioning system, i decided to go with tdh. the decision was made from a combination of price and the knowledge and expertise of mark who provided the original estimate and follow up discussions with tim the owner. the installation went flawlessly and i could not be happier. installers wally, jesus and chris were exceptional. they included me in all decisions throughout the install process. they treated my home with respect and were courteous and very neat through the entire process. i cannot say enough about the quality of the workmanship of this install. it was flawlessly executed and i could not be happier.
