Google Review by Karen B.:
“I found my review of Davis & Davis on this website from two years ago, and my opinion has not changed. After more than10 years of service calls, Davis & Davis continues to be very professional. Their technicians arrive for appointments on time, and they are skilled at what they do when it comes to keeping your air conditioning and heating systems functioning properly. They even showed me how to maintain my a/c system by making sure I change its filter once a year.

Their most recent visit involved tightening screws on a heavy indoor return grill that was on the wall next to our steps. I feared that it would eventually fall and hit someone or something. Tom took care of the problem by securely tightening those screws.

If you are looking for quality service, I highly recommend this company. ”
