Let me preface with this first: Comfort Zone Service will be our new HVAC company from now!

We had issues with our thermostat and furnace since yesterday. Of course, we would have issues with heating during the first freeze of the season. Luckily, we did have some heat overnight, but upon waking up this morning, we were in for a rude awakening, the heat had stopped. Now that's a wake up call! We tried everything with the thermostat, but nothing seemed to work.

This could only mean one thing, we needed to call in the professionals. But we didn't know who to turn to. We of course went to Yelp, and found Comfort Zone Service. They had great reviews and seemed like a good business, so we gave them a call. I was greeted warmly, explained the issue and was told that a tech would call me back. Within minutes, Glen called me back and was ready to take on the problem. I was beyond thrilled!

Glen, arrived promptly and we knew we would be in good hands. He was very courteous with the upmost professionalism. He immediately got to work and was able to diagnosis the issue within 10 minutes. He gave us a quote, which encompassed labor and parts and it was a fair price. He was able to fix our issue in no time! By far, this has been the best maintenance call we ever had!

Thank you Glen and Comfort Zone Service, for not only coming to service our call the day of, but making the whole experience a breeze! You will definitely be handling all of our HVAC needs from now on and furthermore we will be recommending you guys to everyone we know!

Furnace went out. Tried several different companies some said it would take days to come, by the way it was freezing outside/inside. Called Comfort Zone and technician called me back in 5 minutes and showed up at my door in 15 minutes. Problem diagnosed and fixed very quickly, luckily it was just the ignitor! Glen the technician was great. Would definitely use again.
