“⭐️⭐️⭐️⭐️⭐️ Exceptional Service from David Hernandez at One Hour Air Conditioning! We can’t say enough great things about David Hernandez! Every time he comes out to our home, he remembers us and treats us like family — it’s clear he genuinely cares about our comfort and well-being. It’s rare to find someone who brings not only technical expertise, but also warmth and consistency to their work. David is always efficient and respectful of our time. He gets the job done right the first time and never leaves us with unanswered questions. What really stands out is how reliable he is — he always follows up after a visit and makes sure everything is running smoothly. We truly feel taken care of. He’s also great at recommending helpful services that can improve our home, like duct cleaning, without ever being pushy. You can tell he’s looking out for what’s best for our household. David is an incredible technician and a great representative of One Hour Air Conditioning. We trust him completely and appreciate all the care he puts into his work every single time. Highly recommend!”

“Tom was awesome. Found my issue fairly quick. He also mentioned to me of some issues that may arise and recommend semi annual service to keep an eye on the things that may start to develop without trying to sell me upgrades. Thanks Tom and we will see you at our next service!!”

“Our experience was great, they kept us informed and updated on when Daniel would arrive and Daniel was professional and very knowledgeable. He gave us several options and wasn’t pushy. I would highly recommend getting Daniel if you are looking for a quote on A/C repair or replacement.”

“Michael and Austin came out to install a new a/c unit. They did a great job! So professional and just fine young men, knowledgeable and kind. My grandchildren (ages 8, 6, and 5) asked lots of questions and they answered them with such kindness. We have used Joe East since 1984. Never have been dissapointed. Great job. Thank you!”

“I will start with the fact that 40 years ago I did AC work. My home AC was not cooling as it should be so I did my troubleshooting and was pretty sure it was low on freon. Our tech was Tony and he was very professional and actually listened to what I had already checked. He hooked up his test equipment and while visually inspecting the outdoor unit he saw that the insulation had oil soaked into it. He showed this to me and I was there when he did a leak test. There was a very small leak and from the looks it wasn’t a very good solder job when it was installed. He made a quick call to get pricing and gave me a quote. He was able to complete the work on the same visit and having watched him do the repair I know it was done right. I wish every person I have had do work for me was as conscientious as Tony. I read some of the other reviews about pressure to purchase there maintenance plan. It was offered to me and I took it. First I got a significant discount on this visit and the plan includes 2 system check visits a year (one AC and one heating) and the plan is only a couple dollars more a year than what two of their competitors wanted for a single system check. So by my math it will save me another $125.00 or so each year. If you don’t normally have your system checked every year then just decline the offer. I will definitely do business with them in the future and I would recommend them to my friends.”

“McCarthy’s service was great. I called for a dryer vent cleaning service, and the technician was over the next day. The technician Jake was wonderful. He came on time and was quick, but thorough. He described everything and talked things through with us. Overall great experience with this company!”

“I have been a customer for over 3 years and have to say they are top notch. Our AC went out late in the evening, when I called not only did they offer some troubleshooting options but scheduled me for first thing in the morning. Our service technician Marcus was amazing! He was professional, knowledgeable, and thorough. He fixed the issue immediately and had our AC up and running efficiently. Thank you, Marcus. Highly recommend!”

“Austin was VERY professional and efficient. He explained the issue completely and how he would correct same before commencing work. He had everything he needed for the job on his work truck. Once finished, he checked the system's operation completely and left the work area clean. We were so impressed, we bought an annual service contract. We highly recommend Austin and One Hour HVAC.”
