What Impacts How Long Your HVAC System Lasts?

Regular Maintenance

Staying on top of routine HVAC maintenance is one of the best ways to extend your system’s life. That means changing your air filter every 1-3 months, scheduling seasonal tune-ups, and addressing small issues before they turn into costly problems. A well-maintained system doesn’t have to work as hard, which helps it last longer.

Your Local Climate

Where you live has a big impact on how much wear and tear your HVAC system goes through. If you’re in a hot, humid area, your air conditioner likely runs almost nonstop in the summer which can take a toll over time. In cooler mountain regions where summers are more mild, including Asheville and Boone, AC systems may last a little longer thanks to less frequent use. The same goes for heating systems in colder climates – they tend to work harder and may not last quite as long.

Quality of Installation

Even the best HVAC system won’t perform well if it wasn’t installed properly. Issues like improper sizing, bad ductwork, or poor placement can put extra stress on the system from day one. That’s why it’s important to hire a qualified, experienced technician who can do the job right the first time. Ask friends and family members for recommendations, or look at a company’s online reviews to help you find a reputable dealer in your area.

Daily Usage

If your system runs 24/7 or you’re constantly adjusting the thermostat, it’s going to wear out faster. Homes with smart or programmable thermostats can give HVAC systems a bit of a break, helping them last longer by reducing unnecessary run time. You’ll also see a noticeable decrease in energy costs.

Brand and Equipment Quality

Not all HVAC equipment is built the same. Higher-end brands tend to use better components and offer longer warranties, which often translates to a longer system life. While you don’t always have to go top-of-the-line, it’s smart to choose a brand known for reliability and long-term performance.

Indoor Air Quality and Insulation

Poor air quality can lead to dirty filters and clogged components, forcing your system to work harder. And if your home isn’t well-insulated, your HVAC has to run more often to maintain comfort. Better insulation and air sealing can ease the load on your system and help it last longer.

Repair History

If you’re frequently calling for repairs, it might be a sign your system is nearing the end of its life. Older systems that break down often can be more expensive to fix over time than simply replacing the unit.

Professional Maintenance Can Extend the Lifespan of Your HVAC System

Regular HVAC maintenance can help your system reach or even surpass its expected lifespan. Professional maintenance should ideally be performed twice a year – once before the heating season and again before the cooling season.

During an HVAC tune-up, a technician will lubricate moving parts, tighten electrical components, clean necessary components, check refrigerant levels (for cooling systems), and test that everything is working properly and safely. They’ll also identify any minor issues and recommend the needed repairs before they balloon into bigger, more expensive problems.
