AC Maintenance Checklist

AC maintenance splits in two: simple tasks you handle (check the filter monthly, keep vents and the outdoor unit clear) and technical work a pro does twice a year (refrigerant, electrical, coil cleaning). Both halves matter when your system runs as much as it does here.

What should I do every month?

In dusty South Texas, the monthly filter check is the habit that protects your whole system:

• Check the air filter monthly. Our dust and long runtime load filters fast. Hold it up to the light — if you can't see through it, replace it. A clogged filter is the top cause of weak cooling and a frozen coil.
• Glance at the outdoor unit. Make sure it isn't collecting grass clippings, leaves, or dust, and that nothing is blocking airflow around it.
• Listen for changes. New buzzing, rattling, or weak airflow is an early warning worth acting on.

What are the seasonal homeowner tasks?

• Keep all vents and returns clear. Don't block supply vents or return grilles with furniture or rugs — restricted airflow makes the system work harder and can freeze the coil.
• Clear space around the condenser. Trim plants back about two feet and gently rinse the outdoor fins each spring (power off first).
• Check the condensate drain before cooling season so summer's moisture drains outside, not onto your floor.

What belongs to a professional?

Anything involving refrigerant or electricity is licensed work, and for good reason. A technician should handle refrigerant pressure checks and leak detection, capacitor and contactor testing, electrical connections, a deep coil cleaning, and verifying your safety devices. That's the core of what's in an AC tune-up — and in our climate it's worth doing twice a year, as we explain in how often to service your AC in South Texas.

How do I keep it all on track?

Do the monthly filter check yourself, and let us own the technical visits. Our VIP Membership covers two professional tune-ups a year, 15% off all repairs, a $0 service-call fee on approved repairs, and priority scheduling for $125 a year — so the pro half of this checklist happens on schedule without you having to call.
