Want your HVAC system to stick around longer and cost you less money? You’re not alone. The average HVAC system in the U.S. lasts about 14 years, but with a little TLC, yours could keep humming along well past that and save you money while it’s at it.
So, how do you get the most out of your HVAC? Let’s break it down.
1. Schedule Regular Maintenance
Think of maintenance like an oil change for your car it keeps everything running smoothly. Ideally, you should service your A/C in the spring and your furnace in the fall. During a Bell Brothers tune-up, we check refrigerant levels, clean coils, inspect motors, and more. This not only boosts efficiency but also helps catch small issues before they turn into big repair bills.
2. Change Your Air Filters
Dirty filters force your system to work harder, and that wears it out faster. Most filters should be changed every 1 to 3 months. Not sure? Check it monthly. If it looks dusty or gray, it’s time for a swap.
3. Upgrade to a Smart Thermostat
Smart thermostats can learn your habits and adjust temperatures automatically. That means less strain on your system and lower energy bills up to 15% savings on cooling, and 10–12% on heating.

4. Improve Your Home’s Insulation
If your HVAC is working overtime because your home leaks air like a sieve, it’s time to improve your insulation. Better insulation keeps your house comfortable and reduces the load on your system.
5. Clean Your Ducts
Over time, dust and debris build up inside your ductwork. This can slow airflow, reduce efficiency, and shorten your HVAC’s lifespan. We recommend duct cleaning every 5 years or so.
6. Don’t Ignore Warning Signs
Hearing strange noises? Noticing uneven temps? Catching issues early can prevent major (and expensive) breakdowns later.
7. Let It Rest When You Can
On mild days, try opening windows or using ceiling fans. Giving your HVAC a break from time to time adds up to less wear and tear in the long run.
Bonus Tip: Keep Your Outdoor Unit Clear
Don’t let leaves, weeds, or debris block your outdoor condenser. A little yard work can go a long way in keeping your system happy.
