Yes, a dirty air filter can cause certain components in your system to overheat—which will eventually force the entire HVAC system to shut down.
You see, your HVAC system needs to “breathe” air in and out in order to cool/heat your home. But a clogged filter restricts the amount of air that your system can breathe in. This lack of airflow can cause various AC and furnace problems—all of which lead to overheating and system shutdown.
This can lead to costly AC repairs over time as your HVAC system becomes overworked. Let’s take a closer look at exactly how a dirty filter affects your air conditioner/furnace.

Replacing your filter before it gets substantially clogged will help prevent expensive repairs (like a burnt-out blower motor).
