Mark Kuykendoll was my service tech on 30 September 2026. Mark provided the fall maintenance on the heating system. Mark was knowledgeable and answered the questions I had. One of the reasons I've recommended Hill-Air Heating & Air Conditioning is because technicians like Mark whom are courteous, helpful, and knowledgeable in what they do. This is why having the right people in your business is good for "word of mouth" which I do highly recommend this business. Thank you for the great service I've received on my heating & air conditioner systems for many years.

Steve was a great tech! Very quick and thorough. He explained everything so that I understood the issue and recommended further preventative maintenance. He also gave me more information about the unit than I previously had, as it was here when I moved in. He did this all at the near end of service hours and was great to talk to throughout. Thanks!
