Wildfire Smoke Days and Your Furnace Filter: What Wisconsin Homeowners Can Do
When wildfire smoke drifts into Wisconsin, a practical step for homes with a forced-air system is to filter the air the system already moves: keep windows and doors closed, use the highest-efficiency filter your system can handle (EPA suggests MERV 13 if possible), and run the fan. Duct cleaning isn't a smoke remedy; consider it only if you see the specific signs EPA describes.

What Air Duct Cleaning Includes (and What It Doesn't)
A thorough air duct cleaning covers more than the vent covers you can see. EPA guidance describes cleaning the whole forced-air system: the supply and return ducts, registers and grilles, and system parts such as the blower, air handler housing, cooling coil, drain pan, and heat exchanger. The usual method is mechanical: loosen debris with brushes or other tools, then capture it with vacuum equipment that either exhausts outdoors or uses HEPA filtration. Cleaning is not duct repair, mold remediation, pest control, or a health treatment, and a good written estimate spells out exactly which parts are included.

When to Consider Air Duct Cleaning
Consider air duct cleaning when there is a specific problem, not just because time has passed. EPA guidance names three situations: substantial visible mold growth inside hard-surface ducts or other system parts, ducts infested with rodents or insects, and ducts clogged with excessive dust and debris or releasing particles into the home from the supply registers. EPA does not recommend cleaning ducts routinely, only as needed, and says there is no evidence that a light amount of household dust in ducts poses a health risk. Whatever the reason, fix the underlying cause first or the problem is likely to return.

What Affects the Cost of Air Duct Cleaning
There is no single fair price for air duct cleaning, because the job changes from home to home. EPA guidance says the cost depends on the services offered, the size of the system, how accessible it is, the climate region, and the level of contamination. The number of separate heating and cooling systems, the duct materials, and whether parts like the blower and coil are included also change the scope. The most reliable way to compare offers is a written agreement that states the total cost and exactly what will be cleaned, before any work begins.

Dryer Vent vs. HVAC Ducts: What's the Difference?
Your HVAC ducts and your dryer vent are two separate systems. HVAC ducts are a branching network that moves heated or cooled air between your furnace, air conditioner, or heat pump and the rooms of your home. A dryer vent is a single exhaust path that carries hot, moist, lint-filled air from the clothes dryer to the outdoors. They collect different material, raise different concerns, and are cleaned in different ways, so cleaning one does nothing for the other.

Signs of a Clogged Dryer Vent
The clearest sign of a clogged or restricted dryer vent is clothes that are still damp at the end of a normal cycle or that take longer than usual to dry. Other signs include weak or no airflow at the outdoor vent hood while the dryer runs, an exterior flap that stays shut, a crushed or kinked duct behind the dryer, and lint collecting around the dryer or the outside hood. Start with the lint screen; if the problem continues, have the exhaust path checked before relying on the dryer.

How to Prepare for Air Duct or Dryer Vent Cleaning
Preparing for air duct or dryer vent cleaning comes down to three things. Before the visit, be clear about why you want the work and ask the provider exactly what is included. On the day, clear a safe path to the furnace or air handler, the registers and return grilles, the dryer, and the outdoor vent hood. Afterward, confirm that access openings are sealed, the dryer is reconnected, and air flows freely out of the exterior hood.
