5 Mistakes Homeowners Make That Kill Their AC’s Lifespan
At Native Air, we know that your air conditioner is more than just a luxury during those hot North Carolina summers—it’s a necessity. But too often, homeowners unknowingly shorten the life of their AC systems through preventable mistakes. We’ve been in the HVAC business long enough to see the same issues over and over, and we’re here to help you avoid them. Here are five common mistakes that can significantly reduce your AC’s lifespan—and what you can do instead to keep your system running strong for years to come.
1. Neglecting Regular Maintenance
Skipping annual tune-ups is one of the fastest ways to send your AC system to an early grave. Just like a car, your HVAC system needs regular care to run efficiently. Filters need to be changed, coils cleaned, and moving parts inspected and lubricated.
What to do instead:
Schedule professional maintenance at least once a year—ideally in the spring before the summer heat hits. At Native Air, we offer affordable tune-up services that can catch small problems before they become expensive breakdowns.
2. Closing Off Vents in Unused Rooms
It might seem like a smart way to save energy, but closing vents actually puts more strain on your system. Your AC is designed to work with a balanced airflow. When you close vents, pressure builds up, which can damage the blower and reduce efficiency.
What to do instead:
Keep all vents open and unobstructed. If you’re looking to control temperatures in different areas, talk to us about installing a zoned system for more efficient climate control.
3. Ignoring Air Filter Changes
We get it—changing your air filter isn’t the most exciting home task. But dirty filters block airflow, make your system work harder, and can lead to overheating or freezing up.
What to do instead:
Change your filters every 1–3 months depending on your home’s air quality, whether you have pets, or if someone in the house has allergies. It’s a quick and inexpensive way to boost efficiency and extend your AC’s life.
4. Installing the Wrong-Sized AC Unit
Bigger isn’t always better. An oversized AC will cool your home too quickly, causing it to short-cycle (turn on and off frequently), which wears out components faster. An undersized unit will struggle to keep up and run nonstop, leading to burnout.
What to do instead:
Always consult with a licensed HVAC contractor (like us!) when choosing a new system. We’ll do a proper load calculation to ensure you get the right size for your home’s needs.
5. Delaying Repairs
We’ve seen too many homeowners ignore strange noises, weak airflow, or rising energy bills—until the AC finally dies in the middle of a July heatwave. Small issues rarely fix themselves. Left unchecked, they snowball into big, expensive problems.
What to do instead:
If you notice something off, don’t wait. Call Native Air. We’ll quickly diagnose the problem and help you make an informed decision before your system takes a nosedive.
Don’t Wait Until It’s Too Late
Your air conditioner is one of the most important systems in your home. With the right care and attention, it can last 12–15 years or more. But neglect and simple mistakes can cut that lifespan in half.
At Native Air, we’re here to help you protect your investment. Whether you need maintenance, repairs, or a brand-new system, we bring years of trusted experience to every home we service in Lowell and the surrounding areas.
