“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.”

“⭐️⭐️⭐️⭐️⭐️ 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.”

“I have used other AC companies in San Antonio, some good, some not so good. One Hour did a superb job of taking care of me and my family and got us scheduled and done before we have some visitors in town. The tech was knowledgeable and helped uncover an issue that the other companies never had. We added a new UV light to wipe out mold before it gets to our air system. Call them if you want good service and good prices.”

“Dalton did a fantastic job repairing our ac unit today, 5 stars all around. He showed up on time and got right to work, going above and beyond by actually crawling under our indoor unit to check the coils. He was very friendly, explaining his repair process and answering all of my questions. I hope we don’t have a need for AC repairs in the future, but if we do, I will definitely request him coming out again!”

“This is the only AC company you need. Amanda and her team (specifically John) came out to my rental property and saved me from having to cancel on my guests. Within two hours John had a solution & my system was cooling my home. Other companies told me it wouldn’t be possible! Professional, fast, knowledgeable, and all did it all with a smile! 10/10 service.”

We worked to build relationships with several lenders to ensure our customers are able to restore comfort in their homes. Ask your technician about your financing options.
Smart thermostats learn a household’s patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.
HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter.
In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house.
Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.
The SEER (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system. The higher the SEER rating, the more efficiently a unit operates. The SEER rating of any given unit can range anywhere from 13 to 21.
At One Hour Heating & Air Conditioning® of San Antonio, TX, we don’t just fix HVAC issues, we deliver custom comfort solutions designed to enhance your home environment. From routine maintenance to full system replacements, our team is committed to ensuring your family’s comfort, safety, and satisfaction year-round.
