H3 came highly recommended from our preferred AC guy Fontaine, who no longer services South Austin. Jason the owner was very responsive and answered all my questions. After much discussion we went with a 3 ton Rheem with great warranty. He was able to get the unit and install it only day after ordering even with the very busy hot summer. Tenants are now cool and happy. Thanks to Jason and his great service and crew. Honest Hill Country HVAC is our now preferred south Austin AC company.

No issues observed so far with the work and they left my house just as they found it. Glad to have worked with Jason and his team.

We worked with Aaron today, Oct. 8,2025. Aaron and the entire team are so professional and courteous. Aaron brought to our attention that our condenser is not performing to like it should and that it will be needing to be replaced. He mentioned that we could replace it today since he had the part available or we could just monitor it. There was absolutely no pressure to have it replaced right then and there just that it would need to be replaced soon, he left all up to me. Every technician I worked have been straightforward about what needs attention. I want to Thank the entire team at Aero Design Systems. You all are a great, friendly, honest team that performs with integrity which is hard to find these days! Keep up the good work. Thank you again!

We paid nearly $600 for an AC repair, and my system failed again within 30 minutes of the…read moretechnician leaving. Thirty minutes. Let that sink in. The technician returned the next day and, instead of standing by the original repair, blamed the attic's humidity and tried to squeeze another $300 out of me. After charging me nearly $600 the day before, they wanted even more money for a problem they clearly failed to fix the first time. Eventually, the technician repaired it again at no charge. Unfortunately, that "repair" was just as worthless as the first one. I also requested an itemized receipt so I could submit the repair for warranty reimbursement. They never sent it. No follow-up. No professionalism. No accountability. Now, only one week later, my AC is out AGAIN. So, to recap: * Nearly $600 spent. * AC failed within 30 minutes. * Attempted upsell for another $300. * Failed to provide the requested documentation. * AC failed again a week later. This company took my money, failed to properly diagnose or repair the issue, tried to charge me more when their repair didn't work, and then disappeared when I needed paperwork. If you enjoy wasting money, sweating, and dealing with excuses instead of solutions, then Honest Air Conditioning is the company for you. Otherwise, save yourself the frustration and call another company.

Another hvac company tried to sell me a new compressor and by the grace of God, Mhuffman came out to find the duct board had a BIG hole and all my cold air for that unit was cooling my attic. They also used a thermal device to show me where I might consider adding insulation in my attic to assist with efficency. Not only was their office and field customer service and communication excellent, they also saved me tons of money AND fixed my problem. I am a property manager and have used many companies over my 40 years and this company is among the best I have ever used. They are now #1 on my list in Marble Falls. I wish I could use them in Austin! You won't be disappointed.

Have you heard your current AC make a small boom? We have…read more I'm grateful we called the right company to help because high temps and high humidity in a two story house is unpleasant to say the least Strategic Air was prompt in answering our call, had friendly service, and expedient in sending someone out. Our unit was 13 years old so her time was done, and now we have a new one that's heavenly. My biggest concern was getting it replaced quickly as we didn't know what to expect (delays due to delivery or too much demand). We had a new one the next day after diagnosis and I'm incredibly impressed at how seamless the whole process was. Highly recommend

Throughout the process Strategic Air Services bent over backwards to make it right and that dear reader, is who you want servicing your HVAC. Chad and his supervisor came out multiple times, including after hours, to keep me comfortable and get to the bottom of the problem. They brought a floor AC unit, ran diagnostics on the outdoor board, corrected previously installed improper wiring, and ultimately replaced the first outdoor Daikin unit late on a Friday night. They rep Daikin because the company is Houston‑based and parts are readily available -- and thank goodness, because otherwise I might still be without AC. Yes, the first Daikin unit had a bad board, that happens in the world of manufacturing. What counts is how a company handles such situations. I was given every consideration, and their attitude, Professionalism, and commitment to making it right was impeccable. I'll continue relying on them for all my HVAC needs.
