Air Conditioner Maintenance: What You Can Do and When to Call a Pro

Do you do regular air conditioner maintenance? Imagine this: It’s the first sweltering day of summer in Rockford. You press the button on your thermostat, waiting for that glorious rush of cool air—only to hear an ominous clunk followed by silence. Like a car that won’t start on a road trip, an air conditioner that quits when you need it most isn’t just inconvenient—it can upend your entire day.

But here’s the good news: most AC meltdowns don’t happen overnight. They build up slowly, one ignored filter and dusty coil at a time. The secret to staying comfortable year-round is simple: air conditioner maintenance. Knowing what needs attention, how often, and what you can confidently do yourself saves money, time, and stress.

Let’s break it down step by step, so you’re never left sweating the small stuff—or the big stuff.

The Heartbeat of Your Home: Why Maintenance Matters

Your air conditioner is like the lungs of your house, drawing in warm air, filtering it, and sending it back refreshed. But just as you wouldn’t run a marathon without preparing, your AC can’t perform its best without a little TLC.

Routine maintenance:

Extends lifespan (often by several years)
Improves efficiency, lowering your energy bills
Reduces emergency breakdowns when you least expect them
Enhances air quality for your family

Regular care is less about perfection and more about prevention—catching issues early before they spiral into costly repairs.

What Should You Do—and When?

Here’s a simple timeline to keep your system in peak shape.

Every Month or Two: Change the Air Filter

The air filter is the first line of defense. A clogged filter restricts airflow, forcing your AC to work overtime and sending your energy bills sky-high.

What Air Conditioner Maintenance You Can Do Yourself:

Turn off your system.
Remove the old filter (note the direction of the airflow arrow).
Slide in a new filter.
Set a reminder on your phone so you don’t forget next time.

Pro Tip: If you have pets or allergies, change the filter every month.

Every Season: Clear the Outdoor Unit

Leaves, grass clippings, and even stray toys can gather around the condenser outside. Imagine trying to breathe through a thick blanket—your AC feels the same way when it’s buried under debris.

What You Can Do Yourself:

Turn off power to the unit.
Remove visible debris.
Use a garden hose to gently rinse the fins (never use high pressure—it can bend them).
Trim vegetation at least two feet away on all sides.

Once a Year: Professional Tune-Up

While homeowners can tackle filter changes and cleaning, certain checks require specialized tools and expertise—like inspecting refrigerant levels, testing electrical components, and calibrating the thermostat. That’s where a certified professional comes in.

When to Call the Pros:

Before the cooling season begins (spring is ideal).
If you hear unusual noises.
If you notice uneven cooling or weak airflow.

This is where Kerley Heating & Cooling shines. With decades of experience serving Rockford and the surrounding communities, their technicians deliver expert solutions that last—not quick fixes.
