Chase, Bruce, Frank, and Brooke are super helpful. I've had 2 units repaired and up and running in no time. Infinity AC of Austin will be my first call for air conditioning issues. Frank made an early morning Saturday trip to take care of us. He has gone above and beyond to make certain things are working correctly. I couldn't be happier about choosing Infinity AC of Austin.

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.

Our HVAC system quit unexpectedly and after getting several estimates we chose to go with Infinity AC and could not have made a better choice. John Cantu came out right away and stuck with us throughout the entire process. John is a tremendous asset to Infinty AC. After receiving help from Carrier, installation of the failed part was scheduled the same day and the Techs Frank & Nick worked until 7pm making sure everything was up and running properly. I highly recommend Infinity AC especially Frank & Nick. If you need HVAC work done don't look any further and make sure you request Frank & Nick to do the work.

Frank came out a few months later to inspect our entire system, and he was great. Excellent customer service all around. I'd definitely recommend Infinity AC. Thank you Frank!
