Thermal Zone Service in Fullerton, CA

I highly recommend this AC repair company! They did an excellent job fixing my air conditioner — fast, professional, and very reliable. I also had my commercial freezer repaired by them, and just like before, the service was top-notch. Their team really knows what they're doing, and they always make sure everything is working perfectly before they leave. Definitely the best repair service I've worked with!

We had an issue with our walk-in freezer and these guys were amazing. They showed up quickly, diagnosed the problem right away, and had everything up and running in no time. Professional, knowledgeable, and very easy to work with. Highly recommended for any commercial refrigeration needs!

I had a great experience with this company! Booking was easy and the staff were super helpful from the start. The tech showed up on time, explained everything in plain words and fixed the problem fast. Prices were fair. I definitely recommend this repair service if you need to solve the problem quickly.

Called them to service a commercial ice machine. They were able to send out a technician the next day. He was able to diagnose the issue and fixed the machine. He also stayed for a few cycles, to make sure the issue was resolved.

We found this company on Google. Iriana is excellent customer service. Alex is genius. He repaired 2 of our refrigerators that had major issues. He found the issue and he fixed it immediately. Request for Alex for sure.

Have a small commercial fridge that was running constantly so needed a check up. seemed the thermostat was broken. got a new one as well as a cleaning of the condensor. working well now hope the electric bill will go down. After a few months I noticed the fixed fridge didn't seem to be working optimally still and had them send a tech out to check. turns out it's a 13 y o fridge with all original parts. a good sign but also a sign that on the original inspection that tech probably should have checked the coolant levels. long story short, turns out after checking the levels were low and more was added. it now is really working as it should. The best part of this review is that after paying, I thought about it more and called them asking for some sort of reduction on the bill as it all could have been addressed in the first visit. I thought only paying for 1/2 of the service fee visit (not the coolant of course) would be a fair compromise. after thinking it over on their end they actually reimbursed me for the entire service fee. I am impressed at their level of service, customer service and business sense.
