Being new to Waco I called Clark Heating and Air on a recommendation from a neighbor who is 20 year customer of Clarks. I am more than pleased with Clarks workmanship, taking the time to explain in detail the issues with my 30 year old AC unit, promptness and fair pricing. Don't hesitate to call Clark! I won't call anyone else!!

We had some strange sounds coming from the furnace. The tech that came out tested and looked and listened to it for a while, long enough to give us a very good explanation of the things we heard. We are glad he was as up to date and knew what to do and how to explain it. Thank you very much, Roger, for sending us a great technician.

On Saturday night, during the height of the recent heat wave, the condenser on my air conditioner went out. On the recommendation of my son, I called Clark’s early Sunday morning. By 11:30 am, a technician had been to the house, diagnosed the problem, and told me my options. If the unit I need is in stock, it should be installed Monday morning. I am impressed by the quick response to my call and the professional diagnosis and explanation. I am confident that I am in good hands and my problem will soon be resolved! So far, I am just as satisfied with Clark’s as was my son when he had his unit repaired several weeks ago!
