David S Ilges
I love their honesty. Mike is very knowledgeable and courteous. We purchased a heater and a/c unit from David ***** 3 years ago and it has had no problems. My gas and electric bill have gone down since that purchase.

We have used Cisco Heating & AC several times over the past five years. The owner, Dave, personally took our emergency call on a Sunday & was at our home within a few hours. We HIGHLY recommend Dave and his team for any type of heating or cooling needs a home would have. All of our needs have been handled in a timely, professional, honest and personable manner. Thanks, Cisco Team-you all do GREAT WORK!
Wesley Beigel
I have used Cisco Heating & AC for my 2019 annual heating/AC inspection and to install a gas line to my fireplace. For both jobs they had skilled and courteous employees. They provided great service, were on time, and a joy to work with. I highly recommend them and will use them for all my future work.
Ruth M Cox
I have used this company for the past 30 years and have never had an issue. They are courteous, punctual, helpful, informative and honest. I recently had an new ac/heating unit installed and Dave and his entire staff did an excellent job, following through with a slight issue and resolving it the next day. This is a wonderful company that I highly recommend.
