Spring Has Sprung: Hire a Licensed Contractor To Check Your Air Conditioning Unit

AUSTIN – May is almost here and many Texas consumers are already turning on their air conditioning systems for the long summer season. Regular maintenance of your system will extend its life and discover any mechanical issues before they become expensive health and safety issues.

The first step in hiring an air conditioning contractor should be checking the TDLR website ( to make sure that they are licensed by the Texas Department of Licensing and Regulation.

“Hiring a licensed contractor helps ensure the safety of your family and property. Checking whether your technician is licensed is an important step in protecting yourself from shoddy and dangerous work,” said TDLR Chief AC/R Inspector Bill Weatherly.

Performing early, regular maintenance can also help keep your system from breaking down on the hottest day of the year – an expensive and sweaty reminder that upkeep is important.

  • Check equipment cabinets for damage or missing panels.
