Changing your air filters is the most effective maintenance change you can do to ensure your HVAC system runs at peak efficiency. A clean filter removes dust and pollutants from the air, making your indoor environment more comfortable while keeping dirt from building up inside your equipment. Below are a few signs it might be time to swap out your air filter.

5 Signs You Need to Update Your HVAC Air Filter

1. Increased Allergy Symptoms

In addition to keeping dust out of your furnace, the air filter removes pollen and pet dander from the air, which is beneficial for people with severe allergies. Worsening symptoms are a common sign that a clogged filter is allowing your HVAC system to circulate allergens throughout the building.

2. Dust Near the Vents

Along with allergens, an HVAC system with a dirty filter will also spit dust and ash into your building or business. Check for debris on the vent itself, or accumulating on the carpet nearby, and change the filter at the first sign of dust buildup.

3. Higher Utility Bills

Clogged air vents make it harder for your HVAC system to draw in enough air, which uses more electricity. If your utility bills have steadily increased, changing your air filter could bring them back down to cost-effective levels.

4. Strange Sounds

Some HVAC units will make a high-pitched, whistling sound as it draws air through a dirty filter. Ideally, your air intake should be silent, so check the filter if you hear unusual noises.

5. Seasonal Change

As a general rule, you should change your air filter before turning on your air conditioning in the summer or firing up the furnace at the end of the year. However, if your commercial building has poor air quality or your guests have severe allergies, it might be best to change the filter on a monthly basis.
