AC Installation and Repairs in Wheaton, MD

“My old AC gave out. I got 4 quotes, and Davis & Davis had a good price, but most importantly, they had put thought into their proposal. My old AC was sized for the entire house, but when we had renovated, we put in a second unit upstairs. Our old AC was now oversized. D&D identified this and figured out the right size. The other companies didn’t pay attention to this. It came down to trust, and I trusted Davis & Davis. They did a great job on the installation and I am happy with my new system. My stepdaughter has been using them for years and loves them, too.”

Informed At Every Stage of AC Install in Silver Spring, MD

“My 95 year old father’s AC stopped working in this brutal August heat. We called Davis & Davis at 8:30 am in the morning and they came out that day to do an estimate, and on the following day, they installed both a new central AC and furnace (both were 35 years old) in about five hours. WOW. Everyone we dealt with was professional, answered every question, cleaned up after themselves and kept us informed at every stage.”
