Your furnace depends on an air filter to clean the air and prevent dirt from building up in the HVAC system. If your air filter becomes clogged, it can impact the functionality of the furnace. Knowing the details can help you maintain your heater this winter.

What can happen if your HVAC air filter becomes clogged this winter?

If your HVAC air filter becomes clogged, it becomes harder for your heater to push hot air through your HVAC system when it’s trying to heat your home. If the air filter is very clogged, this can cause the furnace to run continuously for very long periods of time. If this goes on for long enough, a safety feature in your home’s furnace will kick on and turn off the burner, causing your furnace to stop working and the HVAC system to blow cold air.

How can you tell if your HVAC air filter is clogged?

If your air filter is clogged, you can tell by pulling out the filter and inspecting it for dirt. You can find the filter in the slot between the return air duct and the blower. If the filter is visibly dirty, there’s a good chance that it’s causing your furnace to work inefficiently. The dirtier the filter is, the more clogged it is.

How can you fix the problem?

To fix the problem, turn off your furnace and remove the filter from its slot. Take the filter to a hardware store or home improvement center, and purchase a filter that matches the size of your old filter. Take the new filter home, insert it into the slot near the furnace, and then turn the furnace back on.

Can you do permanent damage by not changing your HVAC’s air filter?

Using your furnace with a dirty air filter incurs extra wear and tear on your furnace’s motor. Doing this on a regular basis can shorten the service life of your furnace and may cause you to need to replace it more quickly. It may also require you to get heating repairs more frequently because it can cause the parts of your furnace to break down.

How can you avoid this problem in the future?

You can avoid this problem in the future by replacing your HVAC air filter every three months. If your air filter becomes dirty before the three months is up, replace the filter on an as-needed basis.
