  • Paul and everyone from Dependable Heating and Cooling have done full hvac unit installations and repairs for me over the past 15+ years. I can always count on them to be responsive and prompt no matter what day or time I call them. Paul always takes time to answer questions over the phone. Most times, either Paul or one of his other skilled technicians have come out the same day that I call. They have repaired my boiler system at my triplex in multiple emergencies and my next step is to have them install a Combi-boiler system for heat and hot water, to replace the boiler and water heater. Dependable Heating and Cooling is professional, courteous, promptly responsive and reasonable on pricing. I highly recommend Paul for all Heating and Cooling needs.

  • Paul came out within a few hours of finding out our AC was not working, on a weekend, durning a heat wave!
    We expected to pay a lot but we didn't. His prices were beyond fair, he was fast and worked clean.
    GREAT GUY!
