“I was not home when tech arrived. He contacted me and was able to come earlier. My son was home. Tech arrived when he said he would. My son stated he was polite and got done what he needed to do in a timely manner. This was not a repair but getting measured for a new unit. No cost involved.”

“Raoul G. was extremely polite and explained what the issue was and how it was caused (layman’s terms: drainage was clogged ,water was collecting and causing AC not to cool). He also took the time to provide tips to ensure it doesn’t happen again. (Posted on behalf of my parents)”

“Called at 3:58pm, got a call back at 4:03. Appointment made for the same day. Was informed that the tech Anthony was dispatched to my address. He was at my house by 4:50 !!
After a severe storm came thru, we lost power. When the power came back on, the AC wasn't cooling as it normally does. I left for work at 7am, and it was already 74 in the house. By the time my son left for work it was 78.
Anthony showed up, had a quick discussion with me about what happened, and immediately went to the outside unit. He did his diag, tests, checked amperage, verified voltage, signal, and RUN/START capacitor operation. Like a true professional.
He tired some quick tests, made sure it was what he suspected, and gave me a proper diagnosis and explanation. I'm an automotive technician, so I understood what the process was and what he was explaining.
Turns out, the outside unit went bad during the power surge, as I suspected. He was totally professional, spoke clearly, and knowing my level of knowledge in the mechanical side of things, showed me the specs and the actual performance of my outside unit, and the amps it was drawing.
I'm an ASE master technician, so I know bull-crap when I hear it. Anthony gave me straight answers, verifiable proof, and no BS options.
This is the FIRST time I've EVER called an Ac company to come out to me. But with what I've seen, how I was treated, the amazingly fast response, and the brutal honesty I received.....I think I found my new GO-TO AC service company.
I will recommend them to everyone I know that needs AC service.”

“Outstanding Service from One Hour Heating and Air Conditioning!
I recently called One Hour Heating and Air Conditioning when my air conditioner stopped working properly, and I’m so impressed with their service! They arrived within the hour, true to their name. The technician was professional, friendly, and highly skilled. He quickly identified the problem—a clogged drain line—and cleared it efficiently. He also shared helpful maintenance tips to prevent future issues, which I found very useful.
The pricing was transparent with no hidden fees, which I appreciated. After the repair, my system was back to normal, and I noticed improved performance right away. What stood out most was their commitment to customer satisfaction—they ensured everything was working perfectly before leaving. I highly recommend One Hour Heating and Air Conditioning to anyone needing HVAC services. Their promptness, expertise, and dedication to quality make them a top choice. Thank you for a great experience!”

“The technician that came (Ramon) was excellent. He was very knowledgeable and fair with his assessment.
We are signed up for comfort club and got a free systems check. He took his time and told us everything looked good. Nothing extra was pushed on us to buy, he just showed us some things to consider.
Ramon was very kind, knowledgeable, and funny. Easy to talk to and a pleasure to be around. 5 ⭐”

“These guys are great, especially the tech Hunter was very professional and knowledgeable. Their Hero program for a free system check and filter change is legitimate, I’ll be honest I was skeptical about some fine print but nope it is truly free. The owner Justin was incredibly nice as well. Love that they are genuinely giving back to the veteran and first responder community. Would 100% recommend them to everyone I know. And they for sure will be getting all my business in the future.”
