Brand new HVAC system installed by others. Guys that installed it didn't know how it operated sent us down a bad path and the unit would do nothing but blow heat with it being 85° outside. Original installer came out spent an hour fumbling around and couldn't correct the problem. Called One Hour, they asked if we could wait till morning which we could. Asked me to take pictures of unit and controls and send that night so they could be prepared. They sent Oscar. Oscar is very personable, well spoken, and listens to the client. Numerous issues including fact that our one compressor outside was not grounded. Oscar took care of a number of issues. System is operating perfectly. Specifically told contractor wanted controls that would allow us to keep the house within a bandwidth of heat and cold and the Sensi controller did not have that function, in addition to which it was malfunctioning. Would highly recommend One Hour Heating and Air conditioning and because of that we signed up and paid for their membership. Here in Texas when you need heat or you need air conditioning you need a system that works and a company that will respond and knows what they're doing. They may not be the cheapest, but my time is worth money and the other original installer wasted a lot of my time and our house was 82° for the better part of the evening. One Hour Heating and Air Conditioning is worth every dime.

Oscar was such a professional and knowledgeable technician. He was on time and displayed exceptional communication. Everything was patiently explained and he was polite and friendly throughout the service. This company proved itself trustworthy and reliable from the start. Customer service is the number one reason for our loyalty to certain businesses, and One Hour Heating & Air Conditioning hit the mark. I highly recommend them!

Oscar was outstanding! He walked me through the process and what potential issues I may be having. Explained the whys and what options I had. I was able to make a decision without obnoxious pressure. Afterwards, he got me set up and now my heater is fixed just in time for the weekend freeze. Most importantly, my wife and daughters will be happy. Thanks! Much better than Goettl and super happy to be able to support a Woman Owned Small Business. Take care of this gentleman, he’s the right type of employee.

⭐️⭐️⭐️⭐️⭐️ I can’t say enough good things about Oscar from One Hour Heating $ Air Conditioning and the work he did on our AC system. From the moment he arrived, he was professional, punctual, and incredibly knowledgeable. He took the time to explain exactly what was going on with our unit in a way that was easy to understand, without ever making us feel rushed or talked down to. Oscar was extremely thorough in his inspection and diagnosis. Instead of just offering a quick fix, he walked me through the root cause of the issue, explained multiple options, and was honest about what was necessary versus what could wait. That level of transparency is rare these days and builds a lot of trust. You can tell he genuinely cares about doing the job the right way, not just getting in and out. What really stood out was his attention to detail and work ethic. He treated our home with respect, kept everything clean, and made sure the system was running perfectly before he left. He double-checked his work, answered every question I had, and made sure I felt confident about the repairs and ongoing maintenance. On top of being a skilled technician, Oscar was just a great person to deal with—friendly, respectful, and professional the entire time. Our AC is running better than it has in a long time, and the difference was noticeable immediately.

Our heater went out during the ONE week of the year that we need it here in Texas. We called One Hour based on Google reviews and the convenience of being able to schedule online - it was definitely the right choice. We were extremely happy with the service we received from Kirk, Amanda, Oscar, Andrew, and the team at One Hour. They were responsive, explained the problem clearly, and were transparent and reasonable with costs and time. We would definitely use them again—we value supporting a local, family-owned business, and they absolutely delivered.
