B&B Air Conditioning & Heating Service

At B&B Air Conditioning & Heating Service, we’ve served the DMV since 1957, growing to seven office locations while staying focused on the values that guide our work: professionalism, honesty, integrity, and investment in the communities we serve. With more than 68 years of HVAC experience, we bring an established team approach and a strong work ethic to helping customers stay comfortable.

Our factory-trained technicians provide heating, air conditioning, and indoor air quality services throughout Rockville, Maryland, Virginia, and Washington, DC. Our work also includes geothermal cooling systems. We are certified dealers for York, Carrier, Lennox, and Trane, giving our customers access to equipment from several recognized HVAC brands. As our team continues to grow, we remain committed to quality service and effective solutions suited to each customer’s comfort needs.

Training is an important part of how we work. We operate our own in-house training institute, helping our professionals continue building their knowledge and maintaining the standards we expect on every job. This investment in our people supports the organized and professional service we strive to provide, whether we are helping with heating, cooling, or indoor air quality.

Comfort problems do not always happen during regular business hours, so we maintain a 24/7 emergency services hotline for customers in the areas we serve. Whether someone in Sterling needs assistance with heating, air conditioning, indoor air quality, or geothermal cooling, they have a direct way to reach our team. We approach every job with the experience, community values, and straightforward service that have shaped our work for decades.
