On 12/8/2025 Mirka D had this to say:
Hart Plumbing and Heating is one of the best companies out there. Incredibly responsive and very professional. My heat went out in the evening and they came over within couple hours and fixed the issue. Kevin Hart (the owner) goes out of his way to make sure customer is satisfied. His supporting staff is great in coordinating all their needs. Highly recommended if you need quality work.

On 11/18/2025 Skip R. had this to say:
Hart plumbing and heating came to our rescue. Our steam boiler stopped working and after reaching out to the company we rent our conversion oil burner from that service man said it was an electrical problem. We contacted our electrician and he said it wasn't an electrical problem it might be a boiler issue so we contacted Hart Plumbing and heating. The owner Kevin Hart came, found the problem and fixed it in an hour and a half. Kevin not only fixed the problem but ordered a back up part in case the it failed in the future. I highly recommend Hart Plumbing and heating for their exceptional service, prompt communication, professionalism, and friendly staff.
