If your electricity bill continues to increase without a definite cause, then it can sometimes be challenging to identify the source of the increment. However, if your electric consumption hasn’t changed, then a malfunctioning AC system is a big factor to consider when investigating.

It is important to keep in mind that your AC system will either have a beneficial or harmful effect on your overall health.

One strong indication that the AC filter needs to be changed is when the back of the machine becomes extremely hot. If the filter is fully loaded with dirt, you might even feel excess heat coming out of the back of the AC system.

When you feel that your air conditioner is not working like it usually does or has been blowing off warm air instead of cold, the first thing you need to inspect is the AC filter.

A dirty air filter does not enable soothing cold air to flow through it efficiently, trapping you in an atmosphere of uncomfortable humidity.

  1. Presence of Dust

Another usual indication of a dirty air filter is the presence of dust on the surfaces and furniture around the vents.
