Our heat pump failed the night before the big heat wave back in late June. We were facing the prospect of having to search for a place to stay cool since all the HVAC companies we called gave us appointment times several days and even weeks away. We called Sullivan late Friday evening and they had a technician here Saturday morning and he fixed the heat pump in about 30 minutes. We needed a part and Arnold the technician had it in the truck! Go figure. Our external thermometer got up to 113 degrees two days later. I can’t speak highly enough of this company. I can’t imagine the misery and discomfort they saved us and possibly the death of my old dog from the heat. Thank you Sullivan Heating & Cooling.

Travis our service tech was friendly and knowledgeable, he explained everything he was doing and why. Fixed the problem and did not leave until he made sure everything was working correctly. Definitely will use Sullivan Heating and Cooling again in the future.

Sullivan installed our new heating system this year and worked with us so the thermostat settings are right. We have been so grateful during this time of hot temperatures we have the service. They do a great job!

My heat pump broke down unexpectedly the night before a record heat wave was expected. I called just about every HVAC company I could find and no one was willing to book an appointment for at least several days out. Most were several weeks. But Sullivan returned my after hours phone call within minutes and had a tech come to my house within a few hours and quickly made the repair. Their work was great, and their prices were fair. These guys are superheros and I can’t recommend them highly enough.

I did some research into how heat pumps worked prior to calling for estimates. Two other companies came out before Sullivan, both lied to me. Sullivan was honest and followed through beautifully, my only regret is that I had forgot to get a bit of cash to tip the installation crew!

Had to replace AC and Furnace. We had great service- the team was responsive, professional, on-time, very polite, and did a great job. Quality and price was also better than other bids. Will use again if ever needed, and will recommend to others!

y got bids from 7 different companies, Sullivan was the best value by far. their installers are super dialed in, skilled in their craft and really nice too.they sent us a check for $600 for a rebate we didn’t know existed, they didn’t have to, but they did and that says a lot about their company

Best customer service ever. Called after hours and within minutes I had the on call tech (Brad) on the line. He spent about 20 minutes helping me troubleshoot, trying different simple diagnostics I could do. Finally came to the conclusion that there was low LP pressure. Sure enough, the LPG tank was empty (stuck level float gave erroneous level reading). Full tank of LPG later and I now have heat.

I have always been happy with the service at Sullivan.They took care of my old furnace for the past twenty years and I recently purchased a new unit from them. Customer service reps and technicians are all friendly and courteous.

Sullivan was great from the first moment when we sat down to pick out our system. We chose a top of the line unit and after it was installed I asked them when they were going to turn it on. They said, “It’s on”, but it was so quiet I didn’t hear it come on. The system’s like a great waiter, invisible until needed and then at your service. The techs are all great too, knowledgeable and professional. Thanks, Sullivan! 😀

WE have had Sullivan perform preventative maintenance service on our heat pump and furnace for the past 8 years. We have been very pleased with their service. Their technicians are friendly, courteous and professional and seem to be knowledgeable and well trained. Emergency service has been responsive and prompt. We would not use any other HVAC service company. WE have had contact with Mark, Steve, Dave and KIm.

I purchased the heating pump system from Sullivan several years ago and have had maintenance performed every six months since, the technicians are very thorough and always tell me how to ensure proper use of the system. Mark advised me about continuous use of the fan. He did a great job, I have also been pleased with Steve’s service. Thank you Sullivan Heating, I will always recommend your company.
