3 Easy Ways to Maximize HVAC System Lifespan

By Angell Aire /

The cost of replacing a home HVAC system is not one many homeowners take on lightly. Thankfully, there are several easy things homeowners can do to make their HVAC system last longer. Depending on your particular furnace or air conditioning unit, the expected lifespan could be from 10 to 20 years.

These simple tips will help you get the greatest longevity out of your home HVAC system so you can stay in comfort and save money.


Change your home air filters

Changing a home’s air filters seems like such an easy task, but you’d be surprised how often HVAC technicians find air filters in poor condition, long overdue for replacing. Dirty or clogged air filters make the HVAC system work harder to push air throughout the home, putting extra strain on the unit. In addition, since dirt and other matter are no longer being filtered from the air, these travel through the ductwork into the home (yuck) and can get inside the components of the HVAC unit, increasing the risk of failure.

Did you know clogged air filters increase energy usage by 15%? While most homeowners are capable of changing the air filters themselves, the old “out of sight, out of mind” adage definitely applies here. Put a reminder on your calendar to change them every 3 months. This simple act could save you a lot of money.


Get regular tune-ups for your home HVAC system

No one likes to be stuck without heat in the cold of winter or air conditioning in the heat of summer. Establishing regular maintenance can prevent HVAC system failures and keep your unit functioning at its best.

Have your home HVAC system inspected by a certified HVAC technician at minimum once a year and ideally twice a year ahead of the switch from furnace to air conditioning and vice versa. The HVAC professional will check for any worn out components that may need repair or replacement, clean and lubricate the system components, and if needed, recharge refrigerant levels and look for leaks. Small regular repairs help save money in the long-run by keeping the home HVAC system in top working order.


Install a smart thermostat

The latest programmable thermostats learn your habits on their own and automatically adjust the heating and cooling schedule to maximize efficiency. When your home HVAC system runs less, it will last longer. Switching from a manual thermostat to one with newer programmable technology can make your life easier and save you money.


When is it time for a new home HVAC system?

Eventually, when your HVAC system reaches the end of its lifespan, it may have trouble keeping the desired home temperature despite regular maintenance. It may be noisy or seem like it’s constantly running, and your energy bills may keep creeping higher and higher. If your system is more than 10 years old and showing these signs, or if it’s in need of frequent or costly repairs, your money may be better spent investing in a new HVAC system. Technologies are continually improving to make units more energy efficient.

A qualified HVAC professional can help make a recommendation on whether to repair or replace your home HVAC system. If you’ve followed the tips outlined in this article, you’ll know you’ve done your part to keep your HVAC system in good working order for as long as possible.

"Jason was very professional and knowledgeable. He gave a summary of everything he did and how our furnace and AC are performing based on their age. Fortunately, we had a good check up and he didn't try to sell us any replacement parts that we didn't need. Highly recommend!"
