7 Simple Ways to Extend the Life of Your HVAC System
Your HVAC system works hard to keep your home comfortable year-round—but without regular care, it can wear out faster than you’d expect. The good news? With just a few smart habits, you can help your system last longer, run more efficiently, and avoid costly breakdowns.
Here are 7 easy ways to make that happen:
1. Change Your Air Filters Regularly
This is the simplest and most effective maintenance task you can do. A dirty air filter restricts airflow, which causes your system to work harder to push out air. That added strain shortens the life of your furnace or air conditioner and reduces energy efficiency.
How often? Every 1–3 months, depending on your filter type, how often you run the system, and whether you have pets or allergies.
2. Schedule Annual Maintenance
Just like your car needs regular oil changes, your HVAC system needs yearly tune-ups. During maintenance visits, technicians clean internal components, check refrigerant levels, tighten electrical connections, lubricate moving parts, and test overall system function.
Regular maintenance:
Keeps your system running safely
Improves energy efficiency
Prevents minor issues from becoming major breakdowns
Book your AC tune-up in spring and furnace tune-up in fall for best results.
3. Keep Vents Clear and Open
It may seem harmless to close vents in rooms you don’t use, but doing so can disrupt airflow and create pressure imbalances that put stress on your system. Similarly, blocked vents (by furniture, curtains, or rugs) prevent air from circulating properly.
To maximize system performance:
Keep all vents open
Ensure furniture isn’t blocking airflow
Dust registers regularly
4. Install a Smart Thermostat
Smart thermostats learn your habits and automatically adjust the temperature to save energy when you’re not home. They can also alert you to maintenance issues, help track energy use, and keep temperatures more consistent.
Benefits include:
Reduced energy bills
Less system runtime (which means less wear and tear)
Remote control from your phone
It’s a small upgrade that pays off in the long run.
5. Clean the Outdoor Unit
Your outdoor condenser unit needs space and airflow to release heat. When leaves, grass, dirt, or other debris build up around it, your system has to work harder, increasing the risk of overheating.
Here’s what you can do:
Clear at least 2 feet of space around the unit
Gently rinse off dirt with a garden hose (never use pressure washers)
Trim back bushes and vegetation regularly
6. Seal Leaky Ductwork
According to ENERGY STAR, homes can lose up to 30% of conditioned air through leaky ducts. That’s wasted energy and money—and your HVAC has to work harder to compensate.
Warning signs of leaky ducts include:
Hot or cold spots in certain rooms
Excess dust around vents
Higher-than-usual energy bills
Have your ductwork inspected and sealed by a professional to reduce strain on your system and boost comfort.
7. Don’t Ignore Strange Noises or Smells
Your HVAC system should operate quietly and without noticeable odors. If you start to hear banging, squealing, grinding, or rattling—or smell burning, mildew, or rotten eggs—it’s a sign something’s wrong.
Potential issues include:
Loose or broken parts
Electrical problems
Mold buildup
Gas leaks (especially dangerous with furnaces)
Addressing these issues early often prevents more serious (and expensive) damage.
