Disadvantages to a Clogged Filter

Reminder:

If your air conditioning’s air filter looks like any of the examples below, it’s time to get a replacement. There are no benefits from keeping a clogged filter, only disadvantages. We’ve made a list below of why it’s disadvantageous to keep a clogged filter:

  • A clogged filter generates higher energy consumption. An HVAC system relies on circulating air. If circulation was cut, say 60%, the fan works harder to draw in that 60% that it isn’t receiving. According to the Department of Energy, a clogged filter can use 15% more energy. That number can be higher or lower depending on how clogged the filter is. This means only one thing: more expensive bills.
  • Clogged filters can cause frozen evaporator coils. The evaporator or cooling coil can freeze up due to the unit’s lack of air to dissipate the condensation produced during the cooling process. In other words, condensation stays and eventually gets cold enough to freeze up.
  • Inadequate heating or cooling. Dust, debris, dander, and anything else stays on a clogged filter blocking airflow. The blower fan will attempt to push the air through the filter to heat or cool a room; hence, not all room will be equal or to its set temperature. The fan will be straining itself to get the room to its desired temperature and at times, won’t be able to.
  • Unhealthy air. Any dust and debris that was filtered out is being re-circulated back onto your home. Self explanatory.
  • Furnace failures. According to the Diamond Certified Organization, a clogged furnace air filter is the primary cause of equipment failure. The equipment is being overworked causing the whole system to fail, which can cause you thousands of dollars compared to the price of a filter.

Depending on the use of your air conditioning and the setting, a filter may need to be changed every 2-3 months or maybe twice a year. Consider checking the filter every two weeks to ensure it’s staying clean and if it isn’t clean, when to replace it.
