B&B Air Conditioning & Heating Service

We’ve been serving our customers since 1957, and we’re proud of the team and culture we’ve built along the way. From our long history in the Rockville area, we have grown from one location to seven across Maryland, Virginia, and Washington, D.C., including our Millersville location. Through that growth, our focus has remained the same: providing quality air conditioning, heating, and indoor air quality work with efficiency, honesty, and integrity at a fair price.

Our slogan, “we are always there when you need us,” reflects our commitment to being available around the clock. We understand that heating, air conditioning, and indoor air quality problems do not always happen during standard business hours—and that some issues cannot wait. When our customers need help, our reliable professionals are ready to respond with an understanding of the situation and a clear focus on the work at hand.

We invest in our people because skilled service begins with thorough training. Our highly trained professionals benefit from the B&B Institute of Advanced Heat Pump Technology, which we founded in 1991. Its rigorous five-year training program has helped prepare skilled technicians for work throughout the HVAC industry. We stand behind the work our team performs with a 30-day guarantee on repairs and a two-year warranty on installations, including a complimentary certified service-maintenance agreement. Whether a customer needs assistance with air conditioning, heating, or indoor air quality, we aim to provide dependable work without unnecessary distractions or added fluff.
