Thomas W.

Mr. Schmid contacted me within 10 minutes of my request for A/C repair. He arrived at my home 1 hr later. He was very knowledgeable and methodical in finding what was wrong with my central air unit, and proceeded to repair it immediately. My unit "broke down" in the midst of the triple digit record high temperatures in St. Louis this summer, and his sameday service was both "on time" and "in time". I was very pleased with all aspects of his repair service and recommend his work very highly.
