Air Duct Cleaning Time

In a typical six-room home, up to 40 pounds of dust is created annually through everyday living. Your heating and cooling system is the lungs of your home. The system taken air in and breathes air out.
You should consider having the air ducts in your home cleaned if:
• There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system.
• Ducts are infested with vermin, e.g. (rodents or insects); or
• Ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.
EPA recommends if you have a fuel burning furnace, stove, or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning. Some research also suggests that cleaning dirty cooling coils, fans and heat exchangers can improve the efficiency of heating and cooling systems.
