What Your Neighbors Are Saying About Us

Don was absolutely fantastic!!! We thought we needed our furnace replaced, but Don checked on a warranty for us, and found that we still had a warranty and they could replace the parts within 48 hours at a fraction of the cost.

They were awesome, very personable and very knowledgeable. I would have him come to my home every time I need help with HVAC needs. He took the time, explained everything to me, treated me with respect, and was very caring.

I had a furnace tune up today. Matt Bates was my technician. He was punctual, extremely knowledgeable and very pleasant. He explained everything he did and respectfully answered all my questions.

Chris and Matt were amazing! Super friendly! Very professional. Walked us through the entire process. Answered all of our questions and did an amazing job explaining everything that was done and how to maintain it! I highly recommend these gentlemen!

A huge thank you to Sullivan's. Came out on Monday and talked about our options. Our old furnace was 40 years old. Time for an upgrade. New furnace was up and running by Friday.

Our previous furnace had given us problems off and on for several years. This year, when we called the Sullivan that installed it, they had difficulty diagnosing the problem, even though they had fixed the same issue multiple times in the past.

My heating system went out the other night and I saw great reviews about Sullivan’s and decided to give them a call. I was so glad that I did! From the first call until the end, it was a positive experience. Jordan came out and was able to find the problem and explained the issue.
