Our Full Story
Comfort you can count on,
since 1992
A&K Service Inc. has roots that run deep in North Atlanta. Our founder has called the Marietta and Alpharetta area home since 1969, and that long history with this region shapes everything we do. When you call us, you're not talking to a regional call center. You're talking to neighbors who know these communities personally.
Our founder entered the HVAC trade in 1972 and graduated from technical trade school in 1974. He spent years building hands-on experience as a partner with another company before launching A&K Service Inc. in 1992. That's more than 50 years of working in this industry, learning what homeowners actually need, and developing the skills to deliver it.
