“Alec and Brian called before the appointment and arrived at the communicated time. They quickly diagnosed the issue and provided multiple options to solve the issue. They treated our home and time with respect. I highly recommend Tellez heating and air.”
“I had a great experience with Tellez Heating and Air. Alec was incredibly knowledgeable, arrived on time, and quickly took care of our air conditioner's service and a condenser replacement. He took the time to explain what was going on and how he fixed it, which I really appreciated. He also provided before and after pictures. Excellent, professional customer service from start to finish. five stars!”
