Sullivan Service Company

In 1964, Sullivan Service Company founder Joe Sullivan recognized a need in the emerging technology industry—air conditioning. He proudly started the brand focusing on homes and installed one of the first residential heat pumps in the state of Alabama. Sullivan Service Company built a reputation in the Birmingham, AL area for providing exceptional services for heat pumps and air conditioners.

Birmingham-owned since 1959, Gas Engineers merged with Sullivan Service Company in 2001 to bring together two trusted companies under the same roof. Both companies share a similar history and we’re proud to have team members from both companies to provide you with your residential and commercial HVAC needs, in addition to indoor air quality services, and more.
