Our AC stopped cooling the house and I noticed that the outside unit's fan was barely moving. I called Dor-Mar and they had Trevon come out in about an hour. He was very friendly and quickly diagnosed and fixed the issue. What a lifesaver!

Andrew L.

The communication was outstanding. The job was done thoroughly and competently. Dave was very helpful with questions I had. First experience with this company and I was very satisfied.
