why is my furnace filter black?

A black furnace filter is a sure sign something is seriously wrong with the internal workings of your furnace. Maybe you’ve just skipped out on replacing the filter for an overly long time, but if you replaced it within the last year, it might be a sign of something like:

  • Inadequate combustion air
  • Carbon monoxide
  • Mold

Inadequate air supply or carbon monoxide can both cause soot to form on the furnace filter. Mold in your home can lead to all sorts of respiratory problems, especially for young children and homeowners over 65 years of age. Carbon monoxide can be flat-out deadly.

Some modern homes are too airtight, resulting in poor combustion air; carbon monoxide can come from a faulty furnace or an adjacent garage. Fortunately for you, Appleby Systems can send a technician to your home 24/7 to diagnose and repair any problem you’ve discovered with your heating and cooling systems.
