5 Tips to Extend the Average Life of an HVAC

Extend Average Life of HVAC

The life of an HVAC system can vary depending on its usage, season, and geographic location. The average life expectancy of an HVAC system can be anywhere from 20 to 30 years. The length of the system’s average life expectancy will depend on various factors like usage, season, and geographic location. Here are five tips you can use to extend the average life expectancy of your system. 

Reduce Humidity in the HVAC System

One way you can prolong the life of your HVAC system is by reducing the humidity in the system. When moisture is present in the system, it can lead to issues such as mold and corrosion. Keeping your system’s humidity below 50% will help to avoid these issues. If you live in a tropical area that has high humidity levels, you may need to invest in a dehumidifier or set up a dehumidification system to manage high levels of humidity. 

Maintain Proper Ventilation

The best way to extend the life expectancy of your HVAC system is to maintain proper ventilation. You should have at least one window or door open an inch per hour on days that are not too cold. This will allow fresh air to circulate through your home and remove stale air, which can cause health problems. Make sure the ventilations are clean and working properly.

Know When to Replace an HVAC System

There are a few signs through which you can find that your system needs HVAC installation or repair. If you notice things like increased energy costs, frequent repairs, or uncomfortable home temperatures and humidity levels then it may be time to replace your system. Another sign is when you notice that the system starts making strange noises or feels loose in some way. You can also check to see if the pipes are leaking coolant or oil. Lastly, if any of the above signs happen too often, then it might be time to replace your system. 

Proper Filters

One way to help your system last longer is to use the right filters. If you use a filter with a MERV rating of ten, you can extend the life of your system by two years.  If you remove the filter altogether, this will shorten the life expectancy of your system by four percent each year. 

Duct Cleaning

One way to help extend the average life of your system is to have your ducts cleaned. Dirty ducts can cause problems for your system, like a decrease in airflow or an increase in electricity usage. Not only will duct cleaning help with the functionality of your system, but it’ll also give it a fresh start and extend its life expectancy. 


Maintaining your HVAC system can be a daunting task. But by following the above-mentioned steps, you can easily extend your HVAC system age. For example, you can replace the filters monthly and regularly maintain the humidity levels. These five tips can help you keep the air in your home comfortable and healthy.
