Infinity AC of Austin really delivered on their service. They did everything as promised and then some. They showed up on time, did not take short cuts in any of their work, very professional, the installation was above my expectations. I highly recommend, Infinity AC of Austin.

Eddy and Frank were great! They were super helpful and took care of an issue with my A/C's drain line in less than 20 minutes. They arrived early and explained everything they were doing. Even gave me some good tips on how to keep the A/C running and prevent drain clogs. Super happy with their hard work! Highly recommend Infinity AC.

Chase did a great job of addressing the problem. We had three techs come out. He was the Only One who solved the Problem.

Frank and Nick did a great job replacing the AC. VERY Professional

Frank was awesome! He came out within 24-hours of requesting service, helped me understand the issue and solved the problem with my AC unit! Infinity AC of Austin, give this guy a raise!

Thank you Frank Stiglitz! He replaced my thermostat, made it quick & easy. Made sure it was heating correctly and also respected my carpet floor during this messy weather!

Frank and Eddie did an excellent job replacing my AC. From start to finish, they were on top of their work, clearly knowing what to do at each step. They worked efficiently and professionally while still being easygoing, which made the whole process smooth. I highly recommend them.

Frank and Eddie came to help install new insulation at our house - they came on time, were very efficient, and got the insulation done super quickly! They also made sure to clean up afterwards, leaving no trace of any insulation left in the house.

Not only did they add the insulation, they also stayed a few more hours to help diagnose some other AC problems we were having, which was incredible of them - they found out that we had multiple filters all on the same unit which was really reducing the airflow.

We’ve been having issues having good air flow into our upstairs for the past few months which has been tough this summer, but thanks to this team it’s finally gotten much better!

Frank and Nick did a great job came through super early and fixed my blower motor in less than a hour! Great service💪

Frank did a great job getting the system up and running, showing us what was wrong. Very curtious and professional. Took the time to double check that system was completely up and running before he left.

Frank S. — Did an amazing job. His knowledge, swiftness, and expertise quickly helped me and my family.

Thanks Frank, and looking forward!

Great service from Chase Barrett — quick, clean, and professional. He got the job done efficiently and left everything spotless.

The technicians (NICK &FRANK) were very helpful. I would recommend both of them. Answered all my questions and kept me updated on the installation work. I would recommend Infinity AC to anyone.

I recently had a 4-ton Carrier AC unit installed by Infinity Texas Air Conditioning & Heating, and the experience was nothing short of exceptional. From the first call to the final install, Chase, John, and Frank delivered top-tier service with professionalism, precision, and genuine care. They clearly know their craft—every step was explained thoroughly, and the installation was flawless. They showed up on time, respected my home, and worked efficiently without cutting corners.

If you're in Cedar Park, Leander, or anywhere in the Austin area, I highly recommend Infinity to anyone looking for reliable, high-quality HVAC service backed by real expertise and genuine care. They’re not just another contractor—they’re the team you call when comfort, trust, and long-term performance matter.

This has been our experience and honest feedback — we truly appreciate Ryan and Infinity Air for their integrity and support throughout our ordeal.

Long story short, we had a horrible experience last week with another company that insisted a part system needed to be replaced. We weren’t convinced, so we reached out to Infinity Air. Ryan provided clarity, reassurance, and genuine willingness to help resolve our HVAC issue.

Ryan is extremely knowledgeable in his field and took the time to patiently explain the problem and the solution needed to fix it.

We highly recommend Infinity Air and sincerely appreciate their exceptional service.

Frank was awesome! Got in and diagnosed as well as fixed out AC in less than 30 min. Super Professional and knows what he is doing.

Frank and Nick are amazing!!! They came in cleaned out the debris that was making smell like smoke. They cleaned the drain that was clogged. Super respectful, and prompt at getting things done. Thank yall very much!!

Frank was an amazing technician. My heater was not blowing hot as soon as the weather started freezing and he came quickly on a Saturday and did an exceptional job.

Nick and frank were great showed up on time, were very professional and made sure to explain the changes to my new heating and ac system at the end before leaving. I would highly recommend them!

Frank and Nick came out today to fix our AC, and they were quick, professional, and respectful of our space. Everything seems to be working well so far — the house is cooling again, which is a huge relief. I Appreciate the fast service and clear communication.

I had a excellent experience with both John Cantu and Frank Stiglitz. John recommended the system I wanted and made sure it was designed to do the job. Frank is a excellent installer and explained what was happening during the install and after. The system he installed meets my expectations.

Frank and Eddie did an excellent job changing out the duct, plenum and making sure the ducts got cleaned out thoroughly. Frank was especially good at explaining everything he was doing. He's a professional with exceptional people skills too
