A dirty air filter can be bad for several reasons. Neglecting your HVAC system's air filter can lead to more than just dusty vents. A clogged filter reduces air quality and spikes energy bills, affecting your home's comfort and efficiency. 

Keeping your air filter clean is necessary, and recognizing when it's time for a replacement can help reduce the cost of using your AC and allergy symptoms. The team at AVU Heating & Air is here to ensure your system operates smoothly through our expert advice and services.

Read on to learn more about why a dirty air filter can be a problem and tips on recognizing when it’s time to replace the filter in your HVAC unit.

Why a Dirty Air Filter Is Problematic

A clogged air filter can wreak havoc on your HVAC system's efficiency and your home's air quality. 

When dust and debris accumulate, airflow is restricted, making your system work overtime to keep temperatures comfortable. The constricted airflow has the potential to damage components within your HVAC unit and might result in expensive repairs and a higher-than-average energy bill. The extra effort required from your unit to compensate for the restricted airflow spikes your energy bills and wears down your HVAC unit faster.

Beyond efficiency, a dirty filter fails to trap particles effectively, letting dust and allergens circulate freely. This can aggravate respiratory issues and allergies, especially for those with sensitivities. Keeping your air filter clean ensures a healthier indoor environment, safeguarding your family's well-being.

Signs You Need to Replace Your Air Filter

Knowing when to swap out your air filter is key to keeping your HVAC system running smoothly. 

Most filters should be changed every 90 days, but factors like the filter type and size, climate, and household conditions like the presence of pets can impact how often you might find it necessary. 

Having a general timeline for replacing your filter is helpful, but due to the above-listed factors, every 90 days might not be sufficient for your household. Here are some signs of a dirty air filter that might indicate it’s time for a change:

Dust Buildup in Your Home

Have you noticed more dust on your furniture lately? A clogged air filter might be to blame. When filters are too dirty, they can't catch dust effectively, letting it settle around your home. Keeping an eye on dust levels can help you recognize when it's time for a new filter.

Weak Airflow from Vents

If the air from your vents feels weaker than usual, like it cannot fully get through, your filter could be clogged. This blockage makes your HVAC system work harder, reducing efficiency and potentially straining its parts. You may also notice that some rooms in your home receive a reduced airflow compared to others.

Rising Energy Bills

An unexplained spike in your energy bills might point to a dirty air filter. A clogged filter forces your system to use more energy to maintain comfort, driving up costs. Watching your energy bills can help you gauge your filter's condition.

Steps for Replacing a Dirty Air Filter

Changing your air filter is simple and can boost your HVAC system's performance. It just requires a few simple steps:

1. Turn off your HVAC system for safety.
2. Find the air filter, usually near the intake vent or blower compartment.
3. Remove the old filter and note its size, printed on the frame.
4. Select a replacement filter matching your system's size and efficiency rating.
5. Insert the new filter, following the arrows on the frame for correct orientation.
6. Turn your system back on and enjoy better airflow and efficiency.
