4 Tips To Extend The Lifespan Of Your HVAC System

Your HVAC system works continuously all-year-round. You can’t expect it to last forever. There will come a time when you’ll have to replace it with a new one. HVAC replacement is one of the most expensive forms of home maintenance work. While you can’t keep this inevitability from happening, you surely can try to extend the lifespan.

The air conditioner can last for 12 to 15 years and the furnace for 20 years on average. You won’t be left with any other option than to replace the HVAC system when your existing HVAC finally gives in. But, you can try to keep your HVAC system from breaking down just yet. We’ve listed down some tips that will help you extend the lifespan of your HVAC system.

1.     Routine Maintenance

Routine maintenance of your HVAC system is essential. You should get your air conditioner tuned up and cleaned in spring and your furnace serviced in early fall. In case there is a severe underlying issue with the system, it will be discovered and fixed during the routine maintenance and inspection. This way, your HVAC system will be ready to perform efficiently throughout the year.

Routine maintenance includes cleaning of the condenser, lubrication of the moving parts, checking the levels of refrigerant, cleaning the condensate drain tube of any buildup, checking for cracks in the heat exchanger, and other similar tasks. It ensures that no existing problem is exacerbated, and your HVAC system lasts longer.

2.     Change Air Conditioner Filter Regularly

The HVAC professional usually changes the filter during the bi-annual maintenance. However, the homeowner should make sure they do it themselves in case it wasn’t done during regular maintenance. The filter should be replaced if they’re too dirty, even if the replacement of the filter isn’t due. The HVAC system has to work harder to be able to circulate the air throughout the home. It can cause the system to suffer and lose efficiency sooner than later. Changing the air filter on a regular basis can extend the lifespan of your HVAC system significantly.

3.     Run HVAC on ‘Auto’ Fan Setting

The HVAC systems have two fan options; auto and on. In the auto-mode, the fan is switched on only when the system is actively cooling or heating. In the on-mode, the fan is switched on throughout. It puts an immense load on the system and can shave off some years from the lifespan of your HVAC. Running the HVAC on auto-mode will help you add a few more years to the lifespan of your HVAC system.

4.     Check the Condenser

A condenser of the HVAC is placed outdoors. It is built to withstand the outdoor elements. However, strong winds and hailstorms can damage it. Moreover, the accumulation of debris around it also affects its efficiency since it requires room to breathe.


Regular maintenance checks and repairs can alleviate any underlying problems in the HVAC system before becoming too serious. It extends the lifespan of the HVAC system, and it lasts a few more years with the same efficiency. To make sure your HVAC is in the top condition, always hire an HVAC professional who knows their job best!
