What to Know About Duct Cleaning

Do a little investigating on your own. Start by having a look at the duct registers or grilles: Are they discolored and coated with fine, dark dust? If you remove the cover, reach into the duct, and wipe its sides with a damp rag, does it come out filthy? If so, you should consider having your ducts cleaned.

How Often Should Air Ducts Be Cleaned

Your ducts should be cleaned every three to five years. Be wary of a contractor who suggests more frequent cleanings.

Additionally, you should have your air ducts cleaned:

  • When you move into a new home unless you know the previous homeowner serviced the air ducts within the last three years.
  • After building a new home. It’s likely the ducts have built-up debris from drywall dust, and other materials used during the construction phase.
  • After completing a home remodeling project. Construction projects spread sawdust throughout the home, and unless you go to lengths to protect the ducts, the dust will extend into the ductwork.
  • If you have pets in the home that shed fur and dander. Duct cleaning and effective home cleaning practices can help to prevent it from spreading throughout the home

What to Avoid When Hiring a Duct Cleaning Company

Professionals warn homeowners to avoid air duct cleaning scams and to stay away from businesses that offer excessively cheap specials that seem too good to be true. Also, it's advised that you be wary of the bait–and–switch. Companies may quote a low price to get their foot in the door, but this leaves you open to “additional charges” that weren’t disclosed when the call was scheduled.

How Much Does Duct Cleaning Cost?

A good duct cleaning costs between $400 and $1,000 and addresses every aspect of the system that air passes over. This includes the furnace, air coils, and central system. Good cleaners will use a Roto-brush machine that loosens debris and simultaneously vacuums it up before it reattaches to the ductwork.

How Long Does Duct Cleaning Take?

Air duct cleaning should take a few hours, typically three to five, for a thorough job. If someone is in and out of your home in less than 1 hour, you may not be satisfied with your results.
