Indoor Air Quality Tips from Maryland’s Top HVAC Contractor
Have you ever removed your air conditioner’s air filter, only to find it covered in a black coating? If your air conditioner’s air filter is dirty or clogged, it will resemble the lint filter screen from a dryer, except black and most likely a bit thicker.
Your air filter may be black for a variety of reasons, including:
- Old age
- Mold growth
- Pet dander
- Tobacco smoke
- Miscellaneous debris
What Happens If My Air Filter Is Black?
When your air filter turns black, 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.
- Increased temperatures – 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.
What Should I Do If My Air Filter is Black?
If your air conditioner is black, we recommend one of two options:
- Clean your air filter if it is washable or vacuum the air filter
- Replace your old air filter with a new one
