Quality, respect, thorough...returning calls or emails in a timely manner, honest business with good work ethics. Wayne and Christal were great! We will only be using Geske Heating & Air from now on."

​5 STARS - R. C. 
"AC stopped blowing cold air. Came here on Yelp and found Geske Heating & Air. The reviews were great and I like the fact that I was able to request a quote via the app and have most of the communication through it. The office did call me for some additional information and explained to me what the service technician would provide me. They were able to come out the next day in the morning, diagnosed the issue, call me to authorize the replacement part and had me up and running in no time. The office and the service Technician Wayne were polite and professional. The price was what I expected for the speedy service and quality of work. Wayne left the part in the box next to the unit so I could see what was repaired. I will keep Geske in my contacts and recommend them to family and friends."

5 STARS - Kurt M. 
"Compressor stopped working last night, was worried we would not be able to get someone out in this heat wave. Wayne was here the next morning and got my unit up and running in a flash. Very professional and courteous, he will definitely be my new AC and heating professional  !!! Thanks Wayne."
