“I had a great experience. From the first call to the final fix, their team was incredibly professional, honest, and respectful of both my time and my home. They showed up on time, explained everything in a way that made sense, and got my system running smoothly without overcharging. What stood out most was the level of customer service—real people who genuinely care. You can tell they value long-term relationships over quick fixes. I’ll definitely be calling them again for any future AC needs and recommending them to friends and family. Honest work. Fair prices. Top-notch service.”

“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.”

“John did a great job today servicing our AC unit. 5 stars! He arrived right on time, communicated what he was doing clearly, and answered all of my questions. I highly recommend One Hour Heating and Air Conditioning, and hope to have John back the next time we schedule service.”

“I have had many different companies in my home for one reason or another over the years but I have to say that none of them compare to the service I received from One Hour! They provided me different options on my A/C issues and even some great finance options so I could spread the payment out over time. The tech was kind and took his time to educate me on everything to the point that I actually understand how my system works now! He wore boot covers the entire time he was in our home and laid down a red carpet to protect our floors while working. A+++. I can't say enough kind things about them!!”

“We needed our AC serviced. My Father had work done by One Hour, and was very pleased. I made an appointment with them; they were very professional. They text me the name and a picture of Jose H. the AC technician. Jose was professional and very knowledgeable. He explained in detail of what needed to be done to fix the problem. One Hour AC gave us a 45 day warranty, as well. I was very happy with their service.”
The “One Hour” in our company name indicates our guarantee to be at your home in the predetermined window, your service call fee is waived.
Yes, we offer emergency services 24-hours a day, year-round.
The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour technician will walk you through all costs using our Straightforward Pricing Guide so there are never any surprise fees.
It’s ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.
Your filter should be changed every one to three months, depending on conditions in your home and your region’s climate.
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.
