Black air filter causes
A black air filter can be caused by the following issues:
- Old age
- Collection of dirt
- Pet dander
- Tobacco smoke
- Hair Collection
- Miscellaneous debris
When your air filter turns black, it is generally a collection of items causing it to look like dryer lint but darker and a bit thicker. The air cleanliness inside your home is significantly decreased in addition to:
Reduced air flow
The air filter inside your AC unit is designed to catch unwanted contaminants in your cooling system’s ductwork and improve the indoor air quality inside your home—including dust, dirt, and other debris that may enter your system. When your air filter is black, filter screen is blocked or clogged. This significantly decreases airflow in your home and causes your air conditioner to run for unnecessarily long periods of time.
Decreased air conditioner efficiency
When your air filter is black and clogged, your air conditioner works harder to keep your home cool than with a clean, unblocked filter. When your air conditioning system works longer and harder to keep your home at a comfortable temperature it’s energy efficiency decreases and results in expensive electricity bills.
Clogged air filters reduce air circulation throughout your home. When cool air cannot circulate from room to room indoor temperatures increase and cause your home and decrease its ability to cool off.
High utility bills
Your air conditioner is powered by electricity. So, a black air filter resulting in decreased air conditioner efficiency can cause your utility bills to increase during the peak of summer.
