"I would absolutely recommend John and Zach! They are very responsive, polite and knowledgeable. They came to my home at 8PM on a Thursday to repair my AC so that my 1&2 year old could sleep comfortably that night. This is my second time using the company and the service and experience was just as great as the 1st time."

Daena Baker

"Highly recommend! We turned on our furnace today and couldn’t get it to start. They fit us in within a few hours of our call on a Saturday and we’re very professional and reasonably priced. Will definitely use them in the future for any HVAC needs."

David Long

“Great, friendly and honest service on a Saturday morning. They were at my house in no time, diagnosed the issue and had me up and running with cool air very quickly. I will definitely use Gili Heating & Cooling again and would recommend them to friends and family. I was very impressed with the service and thought the price was fair as well.”

Joseph Benker

“It is such a relief to have a HVAC company that you can trust and that does great work! These guys are passionate about what they do and they are honest and fair! Thanks guys for easing the burden of worrying about HVAC repairs!”

Doug Devall

“John and Zach run an incredible heating and cooling business. They will call you back, show up when they say they will and be fair and reasonable with their pricing. John is a vet and takes great care of other veterans!”
