About Us

Washington is our home and we pride ourselves on the service that we give to our friends, family and neighbors. Learn about our long history and reputation for excellence as we've lead the HVAC industry in the greater West Sound area for over 25 years.

Our History

In December 1994, Daniel Sullivan started his own HVAC company with just a handful of employees.  Starting out, the business operated mostly in Kitsap and Mason counties but quickly spread to other areas to include Jefferson, King and Pierce to name a few.

As the business grew, Dan purchased Mr. Furnace in July of 2000 and JC Heating in August of 2004 bringing on board the owners of both companies, along with their contacts and customers in the industry.

After 25 years and growing to 32 employees, Dan decided to sell the business and Sullivan Heating & Cooling became partnered with other Puget Sound market leaders to offer enhanced services and products to our clients.  Our sister companies include MM Comfort Systems of Redmond, G & S Heating of Everett, Comfort Mechanical of Auburn and Scribner Electric of Kirkland.

We look forward to continuing our growth in the community by leveraging the strength of our combined companies and through the same quality of workmanship and integrity that we’ve delivered since our inception.

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.

We were very happy with the great service provided by Sullivan's employees. The office staff was caring and friendly. They got us the earliest possible appointment for service. The service technician was prompt, knowledgeabie, experienced and professional. It was a pleasure to work with them and they will be our service provider from now on.

Their representative was courteous, informative, and answered every questions. The gentlemen who installed my furnace and heat pump also were able to answer questions, cleaned up and also showed me how to set my thermostat. Glad I used them and would recommend to everyone
