Why Air Filter Maintenance Is a Must for Healthy Living

In this brief article brought to you by your Neighborly HVAC company, Aire Serv, we talk about what an air filter does, why it matters, and how keeping it clean can lead to healthier living, lower bills, and a longer-lasting HVAC system.

What Does the Air Filter Actually Do?

Think of your HVAC filters as the system’s frontline defenders. Every time your heating or cooling system kicks on, it pulls air from your home, conditions it, and pushes it back through the vents. Before that air goes anywhere, though, it passes through the filter.

The job of the filter is simple but significant: trap dust, dander, pollen, pet hair, mold spores, smoke, and other airborne contaminants before they circulate through your home. Without it, your system would be blowing unfiltered air into your living spaces and clogging up its own internal components in the meantime. Not ideal.

Why a Dirty Filter Is a Big, Bad Deal

If the filter is full and failing, dust and pollutants get recirculated throughout your home. This is especially bad for allergy sufferers or households with kids and pets. But a clogged or dirty air filter can snowball into much larger problems:

• Reduced airflow: A dirty filter restricts air movement and forces your system to work harder and longer to reach your set temperature.
• Higher energy bills: That added strain on the system uses more energy and costs you more month after month.
• Shorter system lifespan: Overworking your HVAC system wears it down faster. This leads to costly heating and AC repair or, worse, an early replacement.

All of that from a dirty filter? Yep. It really is that important.

How Often Should You Change Your HVAC Filter?

The answer depends a little on your home and lifestyle, but here’s a general rule of thumb:

• Every 1–3 months for standard fiberglass filters
• Every 6–12 months for high-efficiency pleated filters
• More frequently if you have pets, allergies, or a smoker in the house

The best habit is to check your filter once a month. If it looks dusty and gray, or you can’t see light through it, then it’s time to change it.

How to Change an Air Filter

We do offer AC maintenance services here at Aire Serv, but if you’re comfortable doing it yourself, then changing a filter is usually a quick job. Here’s how:

• Turn off your system for safety.
• Locate the filter. It's usually in a return vent or inside the air handler.
• Check the size printed on the old filter’s frame. You’ll need the same dimensions for the replacement.
• Slide out the old filter and insert the new one with the arrows in the right direction.
• Turn your system back on and you’re good to go.

Not sure where to start? Or would you rather just let the pros handle it? Call Aire Serv to have a local HVAC specialist come out for a filter change and/or comprehensive tune-up.

Why You Might Want a Pro to Handle It

Changing an air filter is simple enough, but it's hardly a complete maintenance job. When you schedule an HVAC tune-up with Aire Serv, we'll:

• Replace or clean your air filter
• Check airflow and duct integrity
• Inspect and clean coils, fans, and other components
• Test your thermostat and system controls
• Look for issues before they become expensive problems

In short, we’ll make sure your system is breathing easy so that you can, too.
