B&B Air Conditioning & Heating Service

We have served the DMV since 1957, bringing more than 68 years of experience to heating, air conditioning, and indoor air quality work. With seven office locations serving Maryland, Virginia, and Washington, D.C., including customers in Gaithersburg and Rockville, we bring hard work, strong team organization, and a commitment to the communities around us. Our goal is to provide quality service and effective solutions that help meet each customer’s comfort needs.

Our factory-trained technicians handle every job with professionalism, honesty, and integrity. We also host our own in-house training institute. This emphasis on training reflects the standards we bring to heating, air conditioning, indoor air quality, and geothermal cooling system services. Whether we are addressing a heating concern, an air conditioning issue, or an indoor air quality need, we focus on practical solutions.

We are certified dealers for York, Carrier, Lennox, and Trane. We also maintain a 24/7 emergency service hotline for people in our service area. Through decades of serving the region, we have remained focused on quality service and community investment. We are proud to continue serving customers throughout Maryland, Virginia, and Washington, D.C.
