The filter in your HVAC system is responsible for trapping pollutants and allergens from the air. It prevents these particles from distributing throughout your home, improving the quality of indoor air. However, over time, this filter can become dirty and clogged, impacting its ability to work effectively. How can you know when it’s time to replace it? Consider the telltale signs listed below.

How to Know if Your HVAC Filter Should Be Replaced

1. Allergy Spike

hvacIf anyone in your home suffers from allergies, you may notice an increase in symptoms when the filter needs to be replaced, as it won’t be able to effectively trap pollutants and allergens. If this is the case, you’ll notice that symptoms occur when coming home and stop whenever you leave.

2. Dusty Conditions

Additionally, those particles of dust, pet hair, and other debris that make it past the air filter will continue to distribute throughout the home. As a result, you’ll likely notice an accumulation of dust and dirt around the air vents.

3. Old Age

You should also consider how much time has passed since you last changed the air filter. Typically, this should occur about once a month. However, if you can’t remember when that was, it’s best to switch it out just in case.

4. High Energy Bills

A clogged filter prevents air from blowing through the system easily and efficiently. As such, your HVAC unit will need to work much harder to maintain the same temperature — and this will be reflected in your energy bills. If you notice a sudden spike in monthly costs, check to see if the filter is clogged before worrying about other potential issues.

5. Damaged Filter

Finally, checking the condition of the filter can also help you determine if it needs to be replaced. You may notice holes and signs of wear, or it could simply be clogged with dust and dirt. If the filter doesn’t pass your visual inspection, replace it as soon as possible.
