    This is the 2nd time Chris has been my tech. He is explains everything in detail for me and gives recommendations how to keep my units in tip top shape. I cannot express how grateful I am in his approach.

    We’ve used DonMar for 20+ years. They are quick to respond and proactive—without being aggressive—in ongoing maintenance. They aren’t the cheapest company, but their prices are reasonable and their people know what they’re doing. Highly recommend.

    Donmar and their team of experts provide professional and skilled people to help when needed. Their spring and fall service provides needed assurance that my sons' HVAC System performs as needed whether the temperatures outside are hot or cold. We are completely satisfied with the service they provide.
