HVAC Replacement During the Summer in Kensington, MD

“We were out of the country when we had people at our house say that they were hot and it was discovered that the HVAC went out. We decided to replace and not repair due to the cost and age of unit. The office staff and technicians were all kind and easy to work with. They made a big problem much easier to handle.”
– Robert H. in Kensington, MD

Humidifier Repaired in Kensington, MD

“I called Davis & Davis regarding our humidifier which needed to be serviced according to the Home Inspection Report. He offered to come out the same day in about an hour. He informed me of what was wrong and what price the repairs would cost – both very reasonable for each new part. He serviced the humidifier in good time and was pleasant. I was pleasantly surprised that he didn’t try to upsell or overcharge. We will definitely call Davis and Davis again!”
