“The motor blower in our furnace was replaced; Davis & Davis was prompt and efficient in their service. I would recommend them to anyone in need of repairs. No pressure to buy an entire unit when all you need is someone to fix a non-working AC unit in the middle of a heat wave. They were no nonsense and quick to act.”

“Davis & Davis went above and beyond my expectations. The installation was not only prompt but also incredibly thorough. They installed my new system before our vacation because we were concerned about our pets. I did not hear “I told you so,” I heard, “We will be right over.” The installation crew were fantastic and personable.”

“My old AC gave out, and I received 4 quotes. 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. It came down to trust, and I trusted them. They did a great job on the installation and I am happy with my new system.”

“My A/C unit had blown 3 fuses in a month and I couldn’t figure out what was causing it. Davis & Davis was recommended to me by my neighbor. They showed up at the beginning of the 3 hour window. He diagnosed the problem, fixed it promptly and I was only charged the trip fee. I will definitely use them going forward on all my HVAC needs.”
