Had 5 companies come out to bid converting from Oil to Electric heat pump. Jim spent the most time with us to go over every aspect of the project and took our concerns of sewer line going through an open air return seriously (older home).
The contract provided was extremely detailed, and Jim took feedback in how I wanted certain sections to be worded. The price was reasonable compared to the other quotes, and the most descriptive.
The guys took a couple extra days to complete the project then initially planned. They had to get creative with the returns due to the architecture of the home, creating two new return locations and sealing the system off from the sewer pipe. And they had to remove our old oil tank. They were always courteous, efficient and cleaned up all their mess.
Very happy with our decision to go with Davis Modern.

You go with the local company when they have great reviews, and Davis has them.
Even so, I was surprised by the outstanding quality of their service. My aunt (90 y.o.) wanted to have a dual split system in her older home. Their quote was more than fair, and came in under others.
They scheduled us within a week (it was installed in December) and the service was outstanding. Chan and Julian were gentlemen, and were very considerate of my aunt and her home.
While we haven’t used the cooling yet, the equipment that they installed looks great, and the outside looks great too.
My aunt and I are very happy with their service.
