  • Excellent company. Furnace stopped working at night and they called right back and were out that day. I went based on the reviews here to pick a company and I wasnt disappointed. Jerry Jr. came out and gave the options to repair vs replace. I decided to replace and he sent his team the very next day to install, even coming out again himself to oversee the final portion. The team was professional, courteous and kept things very tidy during and after install. Very pleased with the service! ~Tom M.

  • I had a very positive experience with the service team, professional, knowledgeable, experienced, great service, on-time and fair price. Jerry explained my options for a new smart thermostat, he clearly articulated the pros and cons of each option. Jerry was open, honest and consultative about each option, no pressure tactics and seemed to have my best interest in mind based on what I was looking for in a smart thermostat. I would highly recommend Sullivan Heating and Cooling and I am willing to be a reference to anyone who is considering contracting Sullivan Heating and Cooling.. ~Michael B.
