Who We Are
Georgia summers don't negotiate — when a system fails in July, you need a crew that knows DeKalb County's aging duct infrastructure and the load demands that come with it. Southern Mechanical Contractor has operated out of Tucker since before most of the subdivisions around Hammermill Road were finished, handling everything from new commercial installs to the kind of complicated retrofits that other shops won't quote. With a 4.8-star rating across 5 reviews, every job they've touched has left someone satisfied enough to say so.

Walkthrough includedClient Stories
“Had them out to replace a 20-year-old unit at our office building. The crew showed up on time, pulled the old system out without tearing up the ceiling tiles, and had everything running cold before end of day. No surprise charges at the end either.”

“Southern Mechanical is the only contractor I've called twice now. First time was a ductwork job in our older house — they found a section that had been leaking into the crawlspace for years and fixed it right. Second time was a full system swap. Both times, straight answers and clean work.”

“I got three quotes for a new heat pump install and SMC was the only one who actually walked the house and measured before giving me a number. The others just eyeballed it. That alone told me who to go with. System has been running perfectly since March.”
