“DeVonte was our AC tech and did a wonderful job. Price was slightly high imo for a cleaning, but he was thorough and showed me what was wrong and how to fix in the future, which I appreciate. Customer service was prompt in getting someone out to my house, offered flexibility. Overall I feel pleased!”

“Great service! Cobi was polite, professional, knowledgeable, and very thorough while fixing my air conditioning. He took the time to explain the issue and made sure everything was working properly before leaving. It’s not easy to find someone this reliable—highly recommended!”

“Jacobi with One Hour was fantastic. Our hvac system stopped blowing air the day before the temps dropped. He came out on a Saturday and diagnosed the problem and said rather than use them for the repair, I should reach out to the installing company because if they had done their job and registered our system with Trane, the $2000 part would be covered. Those guys didn't, apologized, then offered a 40% "discount" to replace it. Their quote with the bs "discount" was higher than One Hour's quote. So I left them a 1 star review and went with Jacobi and One Hour. He came out and got the job done quickly and efficiently. He communicates beautifully, is super cool, and my dog fell in love with him, lol. When this system needs to be replaced, I want Jacobi doing it.”

“Devonte from One Hour was awesome! He was very polite, very thorough on his check-up for our furnace and explained everything to me afterwards, even showed me the pics he took of the system and suggested possible future work. He was also exactly on time — he showed at 1pm on the dot for a 1-3pm window. We will be going with One Hour for future HVAC needs!”
