Duggan's One Hour Heating & Air Conditioning

I really wish I'd read reviews before joining their discount club. My hvac system is 7 years old. They've come out to repair it 3 times and yet it keeps having problems. They guarantee 2 cleanings a year under their club, we never received it and they only agreed to rectify this after we've moved out- They offered no discount and no refunds for missing the service that we paid for. Only reason they get 1 star instead of 0, all of their technicians are ploute and helpful, just wish they could spread this energy to their management and ownership.
