Five Signs of a Dirty Furnace Air Filter

Air Filter Dirt 1


Dirty Furnace Air Filter Can Reduce Airflow By 60%.

It’s easy to forget about replacing a dirty furnace air filter. But imagine breathing through a dirty dust mask. Sooner or later it gets difficult to breathe and you overheat. That’s what your furnace-ac experiences. Here are five signs of a dirty air filter.

  1. Increased utility bills. Furnace or ac runs too long or even all the time.
  2. Poor air flow. You feel very little air blowing from the register.
  3. Ice forms on piping to your ac. Turn off ac, check filter, run fan until ice melts.
  4. Furnace or ac stops for no reason. The lack of fresh air can cause the furnace heat exchanger to become too warm and deactivate.
  5. Dirty filters can cause short cycling issues and will make it hard to keep your home warm or cool.

Effectiveness of various air filter types.

Cheap air filters can cause problems sooner. Cheap filters should be replaced once per month. If you forget to replace them consistently they can cause more damage to your furnace-ac over time.

Depending on the type of air filter replace every 90 days unless you see significant dust. Have a pet? Consider changing their filter every 2 months. Allergy sufferers and multiple pet owners should change filters monthly.
