Cool guys I dealt with today. They seem laid back and down to earth. I had an interview with them earlier today. Hopefully we can work something out.

They are always respectful, knowledgeable and prompt. Have used them for many years with zero complaints. Some of the new owner changes are frustrating but hopefully they will dial things in.

If you need the electrical done, you should call and wait for Dustin. He is professional, calm, kind and easy to work with. I was in a hurry and went with another company but things didn't work out. Dustin will take his time and do the best he can to help you out. BE PATIENT AND WAIT FOR DUSTIN!!

Started wit Nate the sales gentleman. He was very friend and courteous and explain everything to us of what we needed to get the work done, and gave the options to choose.Carlos and Eddie were amazing. They came on time and started working on installing our central AC. They were very professional and we couldn't be more happier.After they were done, they clean everything up , and put it back the way it was.The guys who came to clean our ductless were very efficient and professional. We will definitely be recommending this company to our friends and families.We will be using this company to maintain our AC and furnish from now on.

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.
