About Gaithersburg Air Conditioning and Heating

Based out of Gaithersburg, MD, GAC Services is a residential cooling, heating, and electrical contractor setting new standards in the Maryland HVAC and electric market. Since 1970, we’ve developed a strong reputation for providing the Montgomery County, Howard County, and Frederick County areas with reliable cooling and heating services. In 2014, we expanded our service offerings to include electrical services—allowing us to offer our customers the same great service in a new area of business.

“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, or maybe as GAC Cooling & Heating!

While our name may have changed, the way we do business hasn’t.

Up-front pricing. 100% satisfaction guarantee. On-time service. Factory trained and nationally certified technicians. Respect for your home.

These are just a few reasons why your neighbors love working with GAC. It is this commitment to excellence, along with our friendly and honest professionals that has helped us satisfy tens of thousands of customers throughout Maryland over the years. And it is this that we consider…

…the GAC difference.
