“I scheduled a free inspection with One Hour Heating & Air of Fullerton and ended up having a quick service done after they pointed out a few issues with my system. The team was professional, explained everything clearly, and didn’t try to upsell me on anything I didn’t need. I feel much better heading into the hot summer knowing my system is in good shape. Highly recommend!”

“I’ve been with this company for 20 years. Chris exemplified the best of ONE HOUR! Super personable!! Highly informative! (the only negative thing I would like to say to the company is that I am and have been on a contract to have you come check my units every six months. This past time, it took eight months and it was only because I called to ask what was going on. I suspect this has happened on some of the other previous visits where more than six months time elapsed. I’ve never said anything about it. From here on out, I will be calling in and scheduling my own appointments. This was a bit disappointing I have to confess.).”

“First time using this part of the trio, (One hour heating and air, Benjamin Franklin plumbing, and Mr. Sparky electrical service), and I'm very pleased with the service we've received. All of the employees we've met and had conduct service on our house have been very pleasant, well mannered, respectful of our property, punctual, and knowledgeable in their craft. I am confident in my recommendation to anyone needing any of their services.”

“James Buzz is amazing! Upfront and gets the job done. Got there in a timely manner and worked in a timely manner to restore my AC. He even went above and had moved my neighbors trash can so the trash man could reach it due to his vehicle blocking it. Definition of going above and beyond the job.”

“Cemy was my ac technician today, he showed up when he was scheduled. Probably the best tech I’ve ever had for any type of job. He quickly figured out the problem and fixed it. In addition, he was engaging in our conversations , and obviously knew what he was doing. My only advice is to find more people like him, truly outstanding!”
