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.

I wanted to wait until all of our repairs were completed before sharing this review, so I could speak to the full experience. One Hour helped us with several items, including surge protectors for both AC units, UV lights, a motor replacement, and an attic fan installation. Christopher was excellent throughout the process. He clearly explained what each repair would provide and how it would support the long‑term health of our AC systems. He also went above and beyond—while working in the attic, he noticed a few air ducts that had been cramped by the builder and were restricting airflow. He fixed them on the spot. It was a small but meaningful gesture that showed real care and attention beyond the scheduled work. We also appreciate the clear line‑item estimates before each job and the convenient online invoices afterward. The only small improvement we’d suggest is a bit more communication around scheduling and estimated completion times so we can plan our day accordingly. Overall, we’ve been very satisfied with the repairs and the excellent service One Hour has provided!
I had a wonderful experience with One Hour Heating & Air Conditioning, thanks to my technician, Crystal. She was incredibly professional, friendly, and courteous throughout the entire visit. She took the time to explain everything to me in a way that was easy to understand, including how my system works and exactly what was going on with it. I really appreciated how patient she was in answering my questions and making sure I felt informed about the repairs and recommendations. It's clear that she cares about her customers and takes pride in her work. I highly recommend One Hour Heating & Air Conditioning, and if you have the opportunity to have Crystal as your technician, you'll be in great hands!
Jordan was great! He was able to get us through 80% humidity and 90° heat. Our unit went out and he was able to get us up and running faster than our friends took on a coffee run. They diagnose the problem and order the part and come back to install- prices are not bad at all. Jordan was super professional trustworthy and went above and beyond. I highly recommend this company
My technician, Ivan, was superb! I had a mess, with water leaking from the pipes, along the front of the unit. My makeshift water collection system kept me sleepless the previous night, trying to prevent water from leaking into the closet space and onto the floor. Ivan may well have been Santa Claus, as he nodded his head, gave me a smile and went right to work. He explained the situation and what was needed to rectify it and he did it. Afterward he checked the entire system for assurance that nothing more needed his attention. He offered an excellent, optional maintenance program to assure future peace of mind. I was also really impressed that he used shoe covers inside of my house. I am definitely a satisfied customer!
Crystal came to service my unit. She saved me some mula. She was very knowledgeable and the education i received out me in the best position to make decision about servicing my unit in a way that prevents costly repairs down the line. I felt that it was like a "pay a little now or pay ALOT later" type of situation. She was very friendly and had a great attitude as well. I really like this company. No matter who I deal with, my experience has been phenomenal! As a business consultant, I can tell you many people are lacking in the customer service department and so this company clearly sets themselves apart!
