What Our Customers Say

    Trammell Crow

    Trammell Crow Company, Dallas

    My long and considerable experiences with your firm were without blemish or disagreement. You installed approximately 3,000 air conditioning jobs for us. We never had a surprise or disappointment.

      Jacob Anderson

      Architect, Dallas

      For the past several years, you have taken care of my heating and cooling needs. In every instance, you have responded quickly to my urgent calls and sent someone with the professional knowledge to correct the problem. I thought that you would like to hear from a very satisfied customer.

        Errol Faeth

        McFadden & Miller General Contractors, Dallas

        Your field mechanics did a great job on my project. The job was put in professionally and they were very cooperative and goal directed. All the material, equipment and manpower were there when needed.

          Tom Leiser


          Your service technician was repairing our air conditioning unit when he discovered something broken. He drove across town in five o'clock rush hour traffic to the only place he could locate the part, then returned to install it that evening. Most companies would have left it for the next day, but not 24 Hour, Ltd.
