Furnaces and AC units have filters designed to catch dust and other solids that pass through the ventilation system. Most homeowners know they should check these filters regularly and change them whenever they appear dirty. However, some still put off or forget about this task because they don’t understand why it’s essential. Here are some of the consequences you can avoid by checking this part regularly.

What Happens If I Don’t Change My HVAC Filter?

1. Low Air Circulation

It’s harder for air to pass through a full filter. As your furnace or AC works, less of that air gets circulated through your home, which means it can take longer for your space to get to the ideal temperature. In extreme cases, you may not be able to get it to a comfortable temperature at all.

2. Poor Indoor Air Quality

When the filter is full, it can no longer catch dust or other allergens as they pass through. Instead, those materials may start to build up in ducts or around vents and continue circulating through your home. These materials can make homes dirtier and even cause respiratory irritation for those with allergies and asthma.

3. High Energy Bills

Even if your home remains comfortable with a full filter, your furnace or AC will need to work harder than usual. This requires more power and causes your equipment to run more often, which often leads to noticeably higher energy bills.

4. Failing Equipment

The extra strain from running your HVAC equipment constantly can also lead to mechanical issues. The machine can wear down faster from overuse or simply shut down because it can't push air through. Replacing the filter regularly can help avoid system failures and expensive repairs or replacements.
