Harrison Township’s Trusted Heating and Cooling Specialists

We’ve used Demer’s Heating for both repairs and a full system replacement. Each time, the team showed up on time, communicated well, and left everything spotless. It’s rare to find a company this reliable. Highly recommend!

Our furnace stopped working in the middle of a cold snap, and Demer’s Heating had a technician out the same day. He explained everything clearly, gave us options, and had the heat back on within an hour. I couldn’t be happier with the service.

From the first phone call to the final inspection, everyone was kind, patient, and respectful of our home. The installers laid down protective mats, cleaned up after themselves, and made sure we understood how to use our new system. That kind of care is hard to find.

We had gotten quotes from a few companies, and Demer’s Heating stood out for their honesty. The price they quoted was the price we paid—no hidden fees. The work was top-notch, and our cooling system has never run better.
