    Our AC went out on hottest day of year. We called and service rep Cesar was there within an hour. He quickly diagnosed issue and provided repaired unit. He gave us three future repair options. The work was completed timely and cleanly. Rep was professional and knowledgeable.

    We had called On the Mark as our A/C went out and out home warranty company was not doing anything to help us. Brent came out and did an extensive review of the system. They were very knowledgeable and up front about everything. When it came time to install we had Jack, Omar and Carlos come out. They were all very professional and did a wonderful job. They went over everything with us and did outstanding work. I would definitely recommend this company to anyone.
