See What Our Happy Clients Say

I had an overall positive experience with everyone I dealt with from getting the quote on the installation to the ultimate completion of the project. They were responsive to my request and appointments were always right on time.

I have used The Heat since we moved in to our house 8 years ago, and they perform maintenance on our aging furnace and A/C. Every service person they’ve sent has been knowledgeable and takes time to explain their process.

Leslie S.

Super professional service! This has to be the best contractor experience we’ve ever had. In-and-out in under 6 hours for a furnace, A/C, and water heater replacement. Clean, efficient, responsive, thorough.
