Hello, My Name is Johnathan Steele, Owner Operator of Show-Me Comfort Heating and Air Conditioning. I started my company with the intent to help and show transparency to my customers and to educate them to the best of my abilities on the system that keeps their Home Comfortable. Most Companies will come in to a house fix the issue then leave… That’s where we try and separate ourselves by finding the culprit, educating our customers on why it happened and how to prevent future problems. \n\nWe at Show-Me Comfort Heating and Air Conditioning take pride in our work, and if we wouldn’t do it in our house we wouldn’t do it to yours.

"Austin was very prompt calling me and was very courteous on the phone. He arrived on time and explained and showed me what happened and gave me options on how he could fix it. I never felt pressured during the process. Very reasonable on pricing too. I would definitely recommend Austin to do any kind of AC/Heating work you need done!"
