Serving St. Louis’s HVAC Needs Since 2001

Since opening our doors in 2001, Mr. Heating & Cooling has built a reputation for doing things the right way—on time, on budget, and with integrity. Our owner, Roland Walton, wouldn’t have it any other way.

We specialize in residential and light commercial services across St. Louis, offering system installations, duct system builds, repairs, and more. As an Ameristar dealer and MBE and DMBE-certified business, we hold ourselves to the highest standards in both workmanship and professionalism.

Our team is licensed, bonded, and insured, and we’re proud to maintain an A+ rating with the Better Business Bureau. Whether we’re installing a new system or making a quick repair, our goal is simple: to leave every customer feeling confident and comfortable.

"The workers from Mr. Heating & Cooling are very professional and they have high integrity. They do quality work. They are very responsive and punctual. I will absolutely continue to use them."
