GAC Services

How Did We Do?

“What do our customers want?” That’s the question that’s been driving the way we do business at GAC from the very beginning—back when you might have known us as Gaithersburg Air Conditioning & Heating!

While our name may have changed, the way we do business hasn’t. The GAC Services team prides itself on upholding the highest standards in heating, cooling, and electrical services. To ensure that we exceed these standards with every visit, our management team routinely reviews customer feedback from satisfaction surveys and online review sites.

Tell Us What You Think!

If you have recently had a GAC Services team member provide HVAC or electrical service your Maryland home, please take the time to rate your experience. Your honest opinions make us better, every day—and allow us to better serve the Montgomery County, Howard County, and Frederick County communities.
