Furnace duct cleaning may strike the casual household handyman as a daunting and time-consuming undertaking. Fortunately, with the aid of this helpful set of instructions, you'll find that cleaning your furnace ducts can be a relatively simple and painless procedure. So if furnace duct cleaning is something you've been reluctant to tackle, you'll definitely want to read on.

Step 1 - Measure Your Ducts and Vents

Begin by using your tape measure to pinpoint the length and diameter of your ducts. These measurements will determine the diameter of the agitation brushes you'll be using, as well as how much whip cable you're going to need. After measuring your ducts, use the tape measure to determine the height and width of all your home's vents. It is very important that your measurements be as accurate as possible, lest you be faced with problems later on in the furnace duct cleaning process.

Step 2 - Cover Your Vents

Now that your measurements have been taken, use your utility knife to cut out sheets of plastic wrap that will be used to cover your home's vents. Next, unscrew your vents and use pieces of masking tape to apply the plastic sheets over the now vent-less areas.

Step 3 - Prepare Your Vacuum Cleaner

First, find an easily accessible vent to act as the vacuum cleaner's suction center. Once you've chosen a suitable vent, cut a hole in its protective plastic sheet. Make sure this hole is big enough to accommodate your vacuum cleaner's upholstery attachment. Next, insert the upholstery attachment exactly four inches into the hole you just cut. The attachment should be firmly held in place with duct tape. Although it may seem tempting, don't fire up the vacuum cleaner just yet.

Step 4 - Prepare Your Hand Drill and Agitation Brush

Attach the proper length of whip cable to your hand drill. Next, carefully attach one of your agitation brushes to the opposite end of the whip cable.

Step 5 - Begin the Furnace Duct Cleaning Process

Having completed your prep work, it's time to begin cleaning. Start by turning on your vacuum cleaner. Then, slowly insert your agitation brush exactly ten inches into the uncovered duct. Now turn on your hand drill, which will rotate the agitation brush, enabling it to clean the dirt and debris that have built up in the duct. Once your whip cable has been fully extended, retract the agitation brush and turn off the vacuum cleaner. After covering up the vent, you may proceed with cleaning another duct.

So there you have it. What once seemed like a highly complex ordeal can be accomplished in five easy-to-follow steps. With this handy guide by your side, you'll never be intimidated by furnace duct cleaning again.
