Josh was great. He came out to service my air conditioner and furnace. He was very friendly and helped me understand the problem and how to fix it. He took the time to explain the situation and assess the best options for the future. I highly recommend!

We had the strangest loud noise coming from our A/C and couldn’t find out why. Josh Berg was the technician who came out and he immediately found the problem and corrected it. He also provided much needed maintenance to our unit. What a relief! I appreciate how easy it is to schedule with Comfort Zone and will call them again when I need A/C service.
