“Excellent service! Requested an appointment for my old Carrier AC unit which had stopped working. Quickly received a one hour window for the next morning. My tech was prompt, nice, and knowledgeable. He was able to assess the issue and provide a quote quickly and painlessly. They replaced the needed part right away. I also had them replace some other old parts and clean my unit. Ask about the OH club, they make it super easy and affordable to sign up and get your yearly AC and heater checkups. Overall, very satisfied with my whole experience, highly recommend!”

“The A/C in our house wasn’t working well, especially during the sweltering heat of this summer, I called One hour heating and Air conditioning, and was glad they serviced Whittier, I didn’t really believe they could finish the repair in 1 hour but it was done quickly and professionally. They also provided me with a guideline on how to properly maintain my A/C unit so I wouldn’t suffer anymore in the summer. Hands-down a great experience and I got very lucky they were able to come right away.”

“I took advantage of the free tune-up offer for Veterans and First Responders, and I’m so glad I did! The team at One Hour Heating & Air in Fullerton was incredibly professional and respectful from the moment I reached out. They arrived right on time, were very thorough with the inspection, and took the time to explain everything clearly. It’s great to see a company that not only delivers great service but also shows real appreciation for those who have served. Highly recommend One Hour Heating & Air—thank you for the great service and for supporting veterans and first responders!”

They showed up right on time, explained everything clearly, and made sure the job was done right the first time. It’s hard to find service this consistent and reliable these days.
