Testimonials

On 2/2/2026 Marge B. had this to say:
We had our furnace go out during the current freezing zero degree blast. We called Dawn Heating because they came out last summer to fix our air conditioner and we were quite pleased with their work. Mark came out within half an hour after speaking with their phone girl. He quickly diagnosed the problem and had our furnace blasting out heat as soon as he replaced the defective part. The bill was very reasonable and service could not have been better. I highly recommend this family owned business. They will be my "go to" whenever I néed service on my units including replacing them.

On 1/19/2026 Donna Mcinerney had this to say:
I'm always satisfied with dawn heating and air. Mark is the best he knows this business.

On 12/5/2025 Jack Cochonour had this to say:
Awesome service. Mark was exceptional and he explained everything he was doing. After my last heating contractor retired and sold out, it was refreshing to find Dawn, a locally owned company. They will now be my go to for any heating and AC issues.

On 10/17/2025 Nora K. had this to say:
Ed and Mark have a textbook knowledge of not only what they Install and service but they also have a comprehensive knowledge Of other systems in need of repair. And if they cannot figure it Out (which is rare),they will brainstorm and network until they do. These 2 guys treat their customers as they would like to be treated. A rare find.
