The GAC Difference
“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.
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. Contact us for a free replacement estimate on a new cooling system or to schedule service today.
