There are many reasons to clean the air ducts in your home. When ducts are clean, the heating system lasts longer (because there is less dirt wearing out its components), we dust less often, and the air we breathe at home is cleaner. For those of us with allergies, this should be a welcome improvement.

Probably you don’t own a high-powered, truck-mounted vacuum system with 150 foot-hoses; perhaps you can't afford the cost of such service. But I am going to tell you how you can clean air ducts yourself. Sure, you won't be able to reach every nook and cranny, but you can still eliminate roughly 85% of the dust in your system without spending any more than the cost of your new furnace filter.

There are many different designs of duct systems, such as attic systems and underground systems, but the theory of cleaning these systems is the same. You may not be able to access all parts of these systems (for example, underground ducts), but you can make a difference in your air quality by cleaning the parts of the system that you can reach.

Step-By-Step Duct Cleaning

1. Cover supply registers. Start by covering up your supply air registers (openings that supply heated air to the rooms) with paper towels. You do this to keep dislodged dust from drifting into the rooms as you work. Simply lift the register, wrap the paper towel over the top of it, and replace it.

2. Turn on fan. You want the fan running while you are cleaning, to move the dust along that you are going to loosen with your banging and brushing. Set the thermostat to "fan on, " and shut off the "heat/cool" mode so that only the fan is running. If you don't have a fan-only option, you can run the heat, or you might take this opportunity to install a newer thermostat with this helpful option.

3. Check filter. Make sure your old furnace filter is in place, so that the dust you knock loose doesn't end up getting pulled into the fan motor.

4. Loosen dust in ducts. Knock loose any buildup of dust in the duct work. Simply take the handle of your brush and begin tapping on any accessible duct work you have in the basement. This will help break up any deposits of dampened dust that may have stuck to the insides of the duct.
