10 Tips to Help Increase the Lifespan of Your HVAC System


Your HVAC system is a critical component in your home and works hard to keep you comfortable. The life expectancy for a well-installed system correctly sized for your home should last between 12 and 17 years. However, it can last even longer if you use the following 10 tips to improve the longevity of your HVAC system.

1. Maintain Filters

Filters get clogged with dust and pet dander. When this happens, it restricts airflow. Your system has difficulty “breathing” and must work harder to circulate air through your home. Constantly dirty filters are a problem for the fan and will shorten your system’s lifespan.

Check air filters monthly and replace especially dirty ones.

2. Keep Debris Cleared From the Outside Unit

Your HVAC’s outdoor unit is constantly exposed to the elements. Wind and rain can cause a buildup of leaves and debris surrounding the unit. This will interfere with airflow and reduce efficiency. Your system will have to work harder than it should and can shorten its lifespan. It can also cause expensive breakdowns during cold snaps and heat waves.

3. Check the Condenser

Your HVAC condenser is designed to withstand the outdoors but can still incur damage from hail or strong winds blowing debris. Periodically check it for signs of visual damage, especially after a strong storm. Consult an HVAC professional if you notice damage. Keep it clear of weeds and other objects to ensure it has plenty of “breathing” space.

4. Inspect and Seal Air Ducts Regularly

Like air filters, clean, properly maintained air ducts are important to your HVAC system’s longevity. Clogged, dirty ducts will keep air from moving through them freely. In addition to your HVAC lasting longer, you’ll have better indoor air quality.

Air ducts that are leaky will also stress your system. Ducts that aren’t properly sealed will allow cooled air to escape. The system will have to work harder to cool your home. A professional HVAC technician will inspect your ductwork and seal any leaks.

5. Ensure Proper Ventilation

Vents and registers blocked by furniture or other objects will impede airflow. This can cause hot and cold spots throughout your home. Uneven cooling will strain the system and reduce efficiency. In the long run, it will reduce the longevity of your system.

6. Use Auto Setting on the Thermostat

A system constantly left in the “on” position will use excessive energy and lead to a shorter lifespan. Use the “auto” switch so that the system can sense when to turn on to maintain the temperature you have set it to. Intermittent running is more efficient and will increase the chances of a long lifespan.

Save the “on” position for times when you need to trap more dirt and dust for allergy sufferers.

7. Invest in a Programmable Thermostat

Get even more energy savings and longevity for your HVAC by switching to a smart programmable thermostat. A smart thermostat will automatically adjust the temperature at night or while you’re away. This eliminates constantly setting the thermostat too low or too high and lowers the workload on your HVAC.

An HVAC professional will install a smart thermometer for you and give instructions on how to use it.

8. Reduce Humidity

When it’s humid outdoors, your HVAC has to work harder to keep indoor temperatures cool and comfortable. This can put a strain on your system. Ask your HVAC professional about installing a whole-home humidifier. Controlling humidity levels will go a long way in prolonging the lifespan of your HVAC system.

9. Upgrade Insulation

The less it runs, the longer your HVAC system will last. One of the most important things to do to reduce run time is to ensure your home has adequate insulation. With the right insulation, your home will hold more cool air inside in hot weather and hold heat better when it’s cold outside.

A professional can check your attic, basement, and wall cavities and advise you on whether or not to upgrade your insulation.

10. Invest in Regular Inspections and Maintenance

The best tip for prolonging the life of your HVAC is regular inspections and maintenance. A professional will check for leaks, clean or replace filters, lubricate moving parts, replace refrigerant when needed, and check for minor problems that may become bigger issues. A good maintenance plan includes having a professional inspection every spring and fall.
