“Technician let me know when he was on his way. Arrived right on time and did a great job. Friendly and professional. Great company to work with and I feel that they offer a reasonable price on their services. Had them install a new a/c and furnace last year. Another good experience.”

“We’ve enjoyed their yearly maintenance program for many years! When we did finally need a new system, they were able to install and have it working with no problems or delays. We have only needed the by-annual check ups – so far. But, the times, I had questions, they’ve been to the house and no charge for the check out. They have quick and easy service web site appointment set up and have always been on time! I will always sign up for Stan’s annual service agreements as it gives me peace of mind and the supported responses I need!”

“The house got hot today. I called Stan’s because they have taken care of us for several years. They had a tech in my neighborhood and he was at my house in 20 minutes! He quickly diagnosed my problem as a burned out fan. He had a replacement in the truck!! An hour after my call there was cold air blowing throughout my house! Excellent value and service.”

Frequently Asked Questions

How often should my HVAC system be serviced?
Icon featuring a downward arrow, indicating a dropdown or collapse action.

It’s typically recommended that HVAC systems receive a check-up every six months to keep everything running efficiently and to prevent breakdowns. However, depending on the condition and age of your system, more frequent services may be required. Our expert technicians in Round Rock will assess your system’s needs and recommend the best course of action to ensure your HVAC remains reliable.

What is the cost of HVAC services in Round Rock?

HVAC service costs can vary based on the complexity and size of the job. At Stan’s, we pride ourselves on offering fair and transparent pricing. After a thorough inspection, we’ll provide you with a clear estimate, often within an hour of our visit.

Can I repair my HVAC system myself?
