I see it every season: homeowners who invested in a good AC system, maybe even had a tune-up last year… but their system is still working harder (and dying faster) than it should.
Why?
Because they’ve got hidden AC killers lurking in plain sight.
Let me show you what they are—and how you can stop them before they cut years off your system’s life.
Ever moved a couch in front of a vent? Put a dresser over an air return? It might seem harmless—but every blocked vent is a blocked airway your AC needs to cool your home.
When airflow is restricted, your system works harder to push cool air where it’s needed. That added strain wears down motors, increases energy bills, and causes uneven cooling from room to room.
Quick fix: Walk through your home today and check every vent and return. Make sure nothing’s blocking them—furniture, rugs, curtains, or clutter. Your AC will thank you.
Here’s something most people don’t realize: a dirty air filter and dirty air ducts create a cycle that keeps recontaminating your system.
If your filter is clogged, dust and debris bypass it and settle in your ducts. Then, every time your system runs, it blows that dust right back toward your filter—and back into your home. The more dust circulates, the harder your system has to work to maintain clean airflow.
Quick fix: Replace your air filter every 1–3 months, depending on usage. And if it’s been years since your last duct cleaning, consider scheduling one. A clean system is an efficient system.
Even the best AC can’t keep up if your home is constantly leaking cool air. Poor insulation around doors, windows, attics, and walls forces your system to run longer and harder—raising your bills and shortening its lifespan.
Signs your home is poorly insulated:
Quick fix: Add weather stripping to doors and windows. Seal gaps you can see. And if you suspect bigger issues, get a professional energy audit to identify where cool air is escaping.
If your ducts have leaks or gaps, your AC could be wasting up to 30% of its cool air before it ever reaches your rooms. That means you’re paying to cool your attic, crawlspace, or inside your walls instead of your living spaces.
And just like poor insulation, duct leaks make your AC work overtime to make up for lost air.
Quick fix: Watch for signs like low airflow, uneven cooling, or higher-than-expected energy bills. If you’re noticing these, it might be time for a duct inspection and sealing.
Your AC doesn’t work in isolation—it depends on your entire home’s setup to do its job efficiently. Small issues inside can add up to big strain outside at the unit.
The good news? Every problem I listed above is fixable—and preventable. And the first step to protecting your AC this summer is a professional tune-up and system check.
