Air duct cleaning is a very important part of HVAC system maintenance and is integral to indoor air quality. The debris that collects in air ducts gets circulated into your house and can cause health problems for your family. In a typical 6 room home, that home can accumulate up to 40 pounds of dust annually!

Another warning that you may need your ducts cleaned is visible mold on or around your duct work. This can be harder to find, but one thing to keep an eye (or nose, in this case) out for is a musty smell that does not dissipate. That musty smell can signal that something is growing just out of sight. Finally, if your ducts are clogged up more than normal with dust, dirt and debris, it is time to have your ducts cleaned. Every time your furnace (or air conditioner) starts pushing air through your home, this debris is entering the air and lowering your overall indoor air quality.
