Professional. Fit me in during a heat wave. Routine service call after buying a house. Everything was running well. Went over maintenance with me showing what to do throughout the year. Will use again.

Dave did an excellent job of installing my new HVAC system. The work was very thorough. He explained everything in detail. His crew cleaned up everything. Prices were very reasonable. I will have him come back for heater and air conditioner tune ups.

David Mazzelli, owner of D.P.M LLC came himself to do the service and maintenance on my heating system. He explained everything in detail what was done. He also did not mind me asking questions. Excellent service.

Dave Mazzilli was a true godsend to me this evening. I’d returned from vacation to find that my AC, which had been running inefficiently, was not cooling the house at all. The indoor temperature was in the ‘80’s. Before I’d even finished booking an online appointment with DPM, Dave called and offered to come to my house after one more appointment. I’m a disabled divorcée with a home that hadn’t been properly maintained for over a decade. Dave quickly identified the problem, made repairs and patiently endured my ignorance about the HVAC system. He instructed me about its maintenance while in a chaotic environment. His price was extremely reasonable, and he went so far as to say he could stay and finesse certain parts of the system, but that it was fine as he’d left it and he wanted to save me money. One of the repairs he made was quoted to me at nearly $900 by a previous HVAC contractor. Dave literally saved me several hundred dollars. I cried after he left, out of gratitude for his integrity, skill and patience. I cannot recommend him highly enough. I’ll never use any other HVAC contractor again.

Dave came out and gave me a free estimate because he was in the neighborhood. He recommended an electrician for part of the project and relayed information to them as a favor. When he came back to do the service he was on time and thorough. Very pleased with communication and professionalism.
