How Often to Service Your AC in South Texas

In South Texas, the honest answer is twice a year — once in spring before cooling season and once in fall before our short heating season. That's more than the national "once a year" rule, and it's because our AC works far harder than most.

Why twice a year here and not once?

In Harlingen and across the Rio Grande Valley, cooling season stretches from early spring well into the fall. Your system runs nearly every day for most of the year, fighting both heat and coastal humidity. All that runtime wears parts faster, so two visits keep the system caught up instead of falling behind.

What should each visit focus on?

• Spring (before cooling): the big one. The system is about to run for months straight, so this visit cleans the coil, checks refrigerant, and tests the parts that fail in heat. Pair it with our summer AC prep checklist.
• Fall (before heating): a lighter visit that confirms your heat pump or heat strips are ready for the handful of cold nights we get, and gives the system a once-over after a brutal summer.

Does maintenance really matter that much?

Two things make it worth it here:

• Warranty: most manufacturers, including Daikin, expect documented annual maintenance. Skip it and you can put your warranty at risk.
• Efficiency and lifespan: a clean, tuned system runs more efficiently, and maintained systems tend to last longer than neglected ones — which matters when the AC runs as much as it does in the Valley.
