How Often Should You Service Your Air Conditioner in Southern California?

Not sure how often your AC needs professional care? Here’s what homeowners in LA and OC should know to keep their systems efficient and long-lasting.

Not sure how often your air conditioner needs service? You’re not alone. Many Southern California homeowners wait until something breaks but regular maintenance can help you avoid emergency repairs and high energy bills.

The Ideal Service Frequency

In a climate like Los Angeles and Orange County, where AC systems work hard for much of the year, experts recommend a professional tune-up at least once annually. The best time? Spring before the heatwaves begin.

Why Annual AC Maintenance Matters

Annual maintenance helps detect issues early, improve efficiency, and extend your system’s lifespan. It includes cleaning coils, checking refrigerant levels, inspecting electrical components, and replacing filters keeping everything running at peak performance.

Skipping Service Can Cost You

Postponing maintenance often leads to breakdowns during the hottest months, when HVAC companies are busiest. Worse, neglected systems consume more energy and wear out faster leading to higher bills and costly replacements.

What the Pros Check

During a routine visit, a technician will inspect the thermostat, blower, condenser, evaporator, ductwork, and safety systems. They’ll also advise on whether any parts need repair or replacement.

When to Call More Often

If your AC runs constantly, serves a large household, or if you have pets or allergies, twice-a-year maintenance (spring and fall) is worth considering. It ensures clean air, balanced temperatures, and fewer surprises.

Don’t Skip the Little Things

Beyond the basics of filter changes and thermostat checks, there are a few easy-to-miss details that can make a big difference. For example, make sure your indoor vents are not blocked by furniture or rugs—  simple oversight can severely impact airflow and system efficiency. If your AC has a drain line, ensure it’s clear and not clogged with debris, which could lead to leaks or moisture issues. Also, listen to your system when it runs. Strange sounds like hissing, rattling, or grinding can be early signs of trouble. Noticing any of these during your tune-up means it's time to act before it gets worse. Addressing these small things now can help avoid a big repair bill later.
