Mike, the service tech showed up early, which was a godsend. He was pleasant and professional and when he was finished, he was clear and concise about the status of our HVAC system. This kind of experience is why we have had a service contract with Daimion for decades!

Jakes work during a furnace diagnostic visit was beyond excellent. He was methodical, thorough, and effective. The explanation of both the problem and resolution were succinct and easy to understand. In working with both in-office representatives and field technicians, we experienced a genuine and professional presentation at all times. Reasonable prices and excellent customer service. We highly recommend this organization.

Very disappointed with this company. Weve had a contract for their maintenance for the past 2-3 years. Last March, they replaced the motor in our heating unit because it was making loud noises. They came back out for their regular maintenance check in October and after the man left, the motor was making the same noise again. When we followed up, we were told the part would be covered under warranty since it was faulty but we would have to pay for the full cost of the labor again. They advised the labor is only under warranty for 3 months, however considering we got it repaired at the end of
