Symptoms of Dirty Air Filters and When to Change Yours

Your HVAC system in Naples, FL, requires clean air filters to run optimally. Learn the signs that indicate it’s time to replace dirty air filters so that your HVAC system operates efficiently.

Increased Energy Bills

Clogged filters restrict airflow. Your HVAC system needs to work harder to do its job when air doesn’t circulate freely throughout it. You’ll notice higher power bills whenever the HVAC system works overtime.

Worse Health

Change the filters if you notice you or family members becoming sick with sinus problems, allergies or other respiratory issues. Your HVAC system works to circulate air and keep your living environment free from harmful contaminants. Operating an HVAC system with dirty filters worsens indoor air quality and exposes your family to negative health issues.

Burning Odor

Dirty air filters eventually cause the HVAC system to overheat. You’ll notice a burning smell coming from the vents once this overheating process occurs.

Don’t wait to replace the filters if you notice a burning odor. Allowing your HVAC system to continuously overheat causes major damage over time as it works harder. You might end up with a major HVAC repair bill as a result.

Cold Air From Furnace

You might instead notice cold air coming from the vents when clogged filters cause overheating. This occurs because the high limit switch gets triggered as the heat exchanger becomes too hot. The burners shut off even though air still circulates to cool off the heat exchanger.

A Dusty Home

Are you frustrated because dust comes back quickly after cleaning your home? Air filters can’t eliminate dust and dirt when debris clogs them. Replace them with new filters, and you should discover a cleaner home.

If you’ve noticed any of the above symptoms and installed new filters, you shouldn’t notice odd sounds, strange odors or cold air coming from the vents anymore. However, if you’re still experiencing a malfunctioning furnace, you need to get it inspected. Contact Key to Cool to schedule your next maintenance appointment.
