Your HVAC system needs regular maintenance to function properly, and one of the most neglected maintenance items is the air filter. Many people don’t even realize their system has an air filter and, after calling for service on a malfunctioning unit, realize that certain components have degraded to the point that they either need major repairs or a whole new HVAC system.
Regular replacement or cleaning of your HVAC air filter will significantly extend the life of your unit, and make it function more effectively. Here’s what you need to know.
How Often Should I Change My Air Filter?
The short answer is: it depends. One of the reasons this task is so often neglected is because there is no simple one-size-fits-all answer. Some places may need a new filter monthly, while others last a year. Many things affect the life of your air filter, including:
- country, suburban, or city living
- smoking vs. non-smoking occupants
- number of occupants
- pets vs. no pets
- size of home
- frequent cooking
- fireplace
- commercial vs. residential use
If you don’t know how long the air filter lasts in your home, check it every three months until it’s time to change it.
How Do I Know It’s Time to Change My Air Filter?
It’s time to check or change the air filter on your HVAC system when you notice the following:
- There’s so much dust on your filter you can’t see the filter material
- Your HVAC system is running more than normal
- There’s more dust in your home than usual
- You notice strange or burning smells near your HVAC unit
Not Sure If It’s Just the Air Filter?
A small investment of time and money to maintain your HVAC air filter will add years to its life and reduce operating costs of the unit. But in addition to keeping the air filter in good condition, your unit needs annual, professional maintenance to make sure it’s operating well.
