Upgrading your system means better performance, lower energy costs, and reliable comfort day and night.

“⭐️⭐️⭐️⭐️⭐️ 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!”

“We were very happy & impressed with ONE HOUR AC. The entire experience from getting a quote, purchasing, installation & after sales service was smooth sailing & super easy. They are thorough, reliable and great to do business with. Special shoutout to the team from salesmen Steve, technicians/installers Kevin, Albert & Bobby who came to install and left our place spotless to after sales technician Dylan who inspected the unit after hours on a weekend to ensure that everything is working well and that the weird smell was normal coming from a brand new unit. These guys are efficient, professional and they definitely live up to their name of ONE HOUR . Great experience & gave us peace of mind as home owners. We highly recommend them. You wont be disappointed!”

“I called on a Thursday afternoon for a quote. One hour had a man on site to collect data in less than 24-hours and was early for that appointment. Approval was given that same day and I had a new working heat pump installed and running by noon the next day. 9/10 for these guys. Would recommend and will definitely use again. I was given before during and after photos. Gustavo and Jesus were both polite and professional. Wish every home technician were as accommodating.!”
