Frequently Asked Questions

For a typical home the general industry range is every three to five years. Homes with pets, allergy sufferers, indoor smoking, recent renovation work or heavy year-round system use often benefit from shorter intervals. The National Air Duct Cleaners Association favors judging the system by its actual condition rather than by a set schedule.

Once a year works as a baseline for most households. Shorter intervals make sense with heavy daily laundry, a large household, pets that shed into every load, or a vent that travels a long distance with several bends before reaching an exterior wall.

The cleaning is completed in a single visit and generally takes about two to five hours. The main variables are the number of HVAC systems in the home, how many supply and return vents there are, and the condition and layout of the ductwork.

Both main trunk lines, every supply duct and vent in the home, and every return duct and vent. Sanitizing and disinfection of the ductwork is included as part of the service, not billed as an extra.

Yes. Drywall dust, sawdust and insulation fibers find their way into open ductwork easily. Schedule the cleaning once the dust-producing work is finished and before the house goes back to normal use — cleaning while construction is still underway means the system fills back up.

No. Duct cleaning is not remediation. If mold, asbestos, lead dust or similar regulated materials are suspected anywhere in the system, those need to be evaluated and handled by appropriately licensed specialists before routine duct cleaning is considered.

It will if a restricted vent was the reason cycles had been running long. A slow dryer is not always a vent problem, though — heating elements, thermostats and moisture sensors fail as well, so if performance does not improve after cleaning, the next place to look is inside the machine.

By the property, not from a flat rate card. The size of the home, the layout of the duct system, how many supply and return vents there are, how many separate HVAC systems the property has, and how much buildup has accumulated all factor in.
