Testimonial Quote

  • Matt was very help full and courteous. He and his crew arrived on date and time agreed to. He and his crew worked hard with the installation. I am very satisfied with our new central air system. I recommend Deer Park Ave Heating & Air Conditioning very highly.

  • We needed our central humidifier to be fixed. Through Home Advisors we found Matt – Deer Park Avenue Heating & Air Conditioning. He was prompt, pleasant and courteous. We were very satisfied with the work and charges. Nancy Kockenmeister

  • Technician arrived immediately, and then helped me trace and untangle the extremely old wiring to reveal that the emergency shut off switch that we were told was disconnected was in fact, connected, and that flipping it back on caused the boiler to immediately start right up. Then he took an extra 15 minutes talking me through how the rest of the system worked and what sorts of stuff I might do myself as a homeowner (not much, but its nice to hear someone explain why). Very pleasant experience.
