I have been using Clark Heating & Air for several decades, During my annual inspection a failing part was discovered but was quickly replaced since they had it on the truck. So happy to feel confident in my aging unit as we head into heavy use season.

Our thermostat screen went blank and left our system inoperable. I called Clark's and they were able to schedule us for next day service. Kyle came out and was knowledgeable and efficient. He had to access the crawlspace to address the issue and had the thermostat (and our system) back up and running in no time. The cost to resolve the issue was included in the service call fee so there were no surprises of cost. We even signed up for the year's supply of air filters for a reasonable price. Overall, happy with the service and will keep Clark's on speed dial for any future concerns, although hopefully there isn't the need. Thanks Kyle, and thank you Clark's!

Got an AC unit replaced and couldn’t recommend Clark Heating & Air enough. Roger and his team are great. He’ll shoot you straight and make recommendations based on what you actually need and want, no sales pitch, just professional logic.

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!

Pleated Filters By the Case

Filters are designed to filter the air and remove most airborne contaminants throughout the home. The MERV scale judges how effectively your filter will trap particles circulating within a confined space. The higher the rating, the greater the number of particles the filter will trap. Our skilled specialists will work closely with you to make sure air quality is safe, ensuring your HVAC system will last longer and your home is less dusty by using MERV filters.
