Troubleshooting Your AC Filter Issues

Having trouble with your air conditioning system? It could be due to a clogged filter. In this article, we'll discuss how to identify and fix any problems with your AC filter.

Signs of Clogged Filters

The most obvious sign of a clogged filter is that your air conditioner won't cool as efficiently as it should. You may also notice higher energy bills due to the unit having to work harder, and an increase in dust and dirt particles in the room.

Cleaning or Replacing the Filter

If you suspect that your filter is clogged, check it for any visible signs of dirt and dust. If there are any, then you should either clean the filter with a vacuum cleaner or replace it with a new one. Make sure you get the right size and type of filter for your unit.

Checking for Leaks

A clogged filter can also cause air leaks in your system. To check for these leaks, inspect all of the ducts and vents in your home for any gaps or holes where air may be escaping. If you find any, seal them up with insulation or caulking.

Checking the Blower Motor

If your blower motor isn't working properly, this could be another cause of a clogged filter. To check if this is the case, turn off your air conditioner then turn on the blower motor - if it doesn't start up right away then it's likely due to a blocked filter.

Checking for Refrigerant Leaks

A blocked filter can also lead to refrigerant leaks in your system - use a refrigerant leak detector to detect any refrigerant that has escaped from your system.


Troubleshooting AC filters can be tricky but by following these steps you should be able to identify and fix any problems quickly and easily!
