"Carnes & Sons has helped me replace two AC units now over the past couple of years. Clint and his team have always been very responsive, knowledgeable and follow through on what they say they will do. They have stood behind their service and products and are the only HVAC company I'll use."

"Wife and I are in our 70s and HIGHLY RECOMMEND Carnes & Sons for any HVAC issue you're having. Background: Our 23 year old unit finally decided to quit for good so we purchased an entire new A/C System from Carnes & Sons last month (outside and inside with a heat pump). ***Keep in mind our inside unit was in the attic so that complicated the tear down and new installation because of the tight proximity.*** Before recommending a particular brand, Mr. Carnes asked us how long we intended to continue to live at our home. Based on our response, Mr. Carnes recommended a brand whose price point was more than fair based on our response and budget. Installation was scheduled 48 hours after purchase and the 2 man crew were fast, efficient, thorough, and explained each phase of the installation in a manner even an old guy could understand. Now, here's the real SEAL of APPROVAL. On Mother's day evening, (approx 10 days after the installation), we noticed a small drip leak from the return register in our bedroom. I called Mr. Carnes who promptly answered and within an hour (on Mother's Day evening), he had one of the installation crew members come out that same evening. We thought it might be a clogged drain line. The finding: The plywood platform (23 years old) had sunk with the weight of the new unit and caused the leak. It was temporarily fixed that evening so we wouldn't have to bear the extreme heat and within 36 hours, Mr. Carnes had his crew back at my home with a new and more improved method of stabilizing the Air Handler where we were assured the problem would never recur. Mr. Carnes earned more than our respect by prioritizing our problem and not make excuses or delay the situation. Our home has two units and this is the second one we have hired Carnes & Sons to replace. We wouldn't consider anyone else and we are a living testimony to their work, prices, honesty, and commitment to their customers. SUPER HIGHLY RECOMMEND The"

"The service was amazing! My AC would not cool down the house, not even at night, and with 103° weather outside I was really worried — especially since I have a 5-month-old. They came out the same night I called, which was so urgent for me, and went out of their way to really investigate the problem. Now my AC is holding steady at 72° without any issues. The team was professional, quick to respond, and made sure everything was working how it’s supposed to. I really appreciate their honesty and great customer care — I’ll definitely be sticking with this company for all future service needs. Highly recommend!"

"I purchased a new AC unit from Carnes and Sons and I couldn't be more satisfied. Carnes and Sons is a family owned and operated business. If you need a new AC or and existing AC repaired, at a fair price, I can guarantee you won't find a better company to do business with than Carnes and Sons. I have had several encounters with Johnathan Carnes and he is outstanding! Don't be fooled by his age. This young man is knowledgeable, courteous, and trustworthy. If you want to do business with a company that has strong ties to the community then don't hesitate to give them a call."

"My wife and I needed a new AC system in March and we interviewed several other AC companies in San Antonio and without a doubt, we made the right choice. We couldn't be happier with the service we received from Carnes And Sons AC. From the very beginning, Clint was professional, honest, and focused on providing the best solution at a fair price. Clint offered an excellent deal without any high-pressure sales tactics, which immediately earned my trust. The Hector and Dorian arrived exactly on time, communicated clearly throughout the process, and completed the work efficiently and professionally. What impressed me most was their integrity—and workmanship! They both genuinely cared about doing a great job rather than simply installing equipment and just leaving. Both Hector and Dorian were polite and courteous throughout the installation process. Clint's personal attention and customer service was outstanding. He treated us like a valued customer, took the time to answer all my questions, and made sure we were completely satisfied with the installation and performance of our system. He texted me throughout the installation to give me updates. It's refreshing to find a company that combines great competitive pricing, exceptional workmanship, reliability, and true customer care. I highly recommend Carnes And Sons to anyone looking for HVAC services. They have earned my trust and future business. Tony and Dela Valdez"

"We bought a new HVAC system from Carnes and Sons at a very reasonable price. Clint was very helpful from the beginning to the end. Gave us all our options. The technicians that came out and installed we're polite, punctual, professional, and very informative of everything they were doing. When they were done, they made sure everything was very clean and ask us if there were any questions that they could help us with. We would strongly recommend this company to friends and family."
