Dirty HVAC ducts can cause:
 Allergies
and respiratory problems. - Indoor
air to be 10-70 times more polluted than outdoor air.
- Higher
heating and cooling costs.
- More
maintenance.
- Fires.
- Mold
and mildew.
- Sick
buildings.
HVAC ducts get dirty in a number of ways:
- Dirt,
pet hair, dust, pollen, smoke, etc. get trapped
in the house and continuously circulate through
the duct.
- Debris
from original construction and any remodeling.
- High
humidity and hot temperatures, combined with cool
air in the duct, creates an ideal breeding ground
for mold, fungus, spores and dust mites.
