“We had a new AC and heating system installed in our home and couldn’t be happier with the experience. From the initial consultation to the final installation, the service was outstanding. The team was professional, on time, and took the time to explain everything. The installation was done efficiently and neatly, and the system works great. It’s rare to find service this reliable! Highly recommended!”

“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!”

“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. I’ll definitely be calling them again for any HVAC needs—and recommending them to friends and family. Excellent service all around!”

“My heater was broke and I knew after 30 years, it was time for a new one. Cody at One Hour Heating and Air conditioning was super helpful and kind. He gave me options of what I can do and in the end I opted for a new heater. Glad I did. It works great. Thank you Cody and team. Lanette C.”
