Frequently Asked Questions About Air Duct & Dryer Vent Cleaning

Have questions about air duct cleaning, dryer vent cleaning or maintaining your home’s ductwork? Mite-E-Ducts has provided professional air duct and dryer vent cleaning services throughout Central Indiana since 1995. Here are answers to some of the most common questions homeowners ask.

What is air duct cleaning?

Air duct cleaning is the process of removing accumulated dust, dirt, hair, debris and other contaminants from the ductwork connected to your home’s heating and cooling system. Professional cleaning addresses supply and return ductwork, main trunk lines and other accessible components of the system.

How does professional air duct cleaning work?

At Mite-E-Ducts, the process includes protecting the home, accessing the trunk lines, connecting a powerful vacuum system, sealing registers, cleaning supply and return vents, cleaning the main trunk lines and plenums, and cleaning accessible furnace, blower and filter areas. Openings created for the cleaning process are then properly sealed.

How often should air ducts be cleaned?

There isn’t one cleaning schedule that’s right for every home. How quickly debris accumulates can depend on factors such as pets, renovations, household activity, the age and condition of the HVAC system, and the amount of dust entering the home.

If you’re unsure whether your ducts need cleaning, a professional inspection can help determine their condition before you schedule service.

How do I know if my air ducts need cleaning?

Some reasons to consider having your ductwork inspected include visible dust or debris inside registers, excessive buildup within the ductwork, unusual odors, recent construction or remodeling, pest activity in the ducts, or simply not knowing when the system was last professionally cleaned.

Will air duct cleaning reduce dust in my house?

Air duct cleaning removes accumulated dust and debris from inside the duct system, eliminating one potential source of particles circulating through the HVAC system. However, household dust can come from many sources, so duct cleaning should not be viewed as a solution for every dust problem.

Does air duct cleaning improve indoor air quality?

Professional air duct cleaning removes accumulated debris and contaminants from the duct system. Because indoor air quality can also be affected by humidity, filtration, ventilation, pets, outdoor pollutants and other factors, duct cleaning should be considered one part of an overall indoor air quality strategy.

Can air duct cleaning help with allergies?

Professional duct cleaning can remove accumulated dust and other debris from the HVAC duct system. However, allergies can have many triggers, and air duct cleaning should not be presented as a treatment or cure for allergies.

Should I have my air ducts cleaned after remodeling?

Yes, it is a good time to have your ductwork inspected. Construction and remodeling can create significant amounts of fine dust and debris, particularly if the HVAC system operated during the project.

Should I clean my air ducts before moving into a new home?

If you don’t know when the ductwork was last cleaned, an inspection can help you understand its condition. Many homeowners choose to have the ducts cleaned before or shortly after moving so they’re starting with a professionally cleaned HVAC duct system.

What should be included in a professional air duct cleaning?

A thorough air duct cleaning should address more than the vent covers you can see from the room. The cleaning process should reach the supply and return ductwork, main trunk lines and plenums, along with accessible areas around the furnace fan, blower and filter.

What is NADCA certification, and why does it matter?

NADCA is the National Air Duct Cleaners Association, an industry organization focused on HVAC system inspection, cleaning and restoration. Choosing a company with NADCA-certified technicians helps ensure your ductwork is being serviced by professionals trained in recognized industry practices.

Mite-E-Ducts uses NADCA-certified technicians for its air duct cleaning services.

Why is dryer vent cleaning important?

Lint and debris can accumulate inside a dryer vent and restrict airflow. That can make clothes take longer to dry, cause the dryer to work harder and contribute to overheating and dryer-related fire risks. Professional dryer vent cleaning removes accumulated lint and helps restore airflow through the vent.

How often should a dryer vent be cleaned?

Cleaning frequency depends on the dryer, household usage and vent configuration. Homes that do a large amount of laundry, have long or complex dryer vent runs, or notice declining dryer performance may need more frequent service.

Rather than relying only on a set schedule, homeowners should also watch for signs of restricted airflow.

What are the signs of a clogged dryer vent?

Common warning signs include:

  • Clothes taking longer than normal to dry

  • Towels or jeans requiring multiple cycles

  • Clothes feeling unusually hot after drying

  • The dryer shutting off before the cycle is complete

  • An airflow or “AF” warning on the dryer

  • Visible lint accumulating behind or around the dryer

  • Reduced airflow at the exterior dryer vent

If your dryer suddenly starts behaving differently, the vent is one of the first places worth checking.

Why does my dryer take two cycles to dry clothes?

A restricted dryer vent is one possible cause. When lint or another obstruction limits airflow, moisture can’t escape as efficiently, which can increase drying times. Dryer problems can have other causes as well, so the vent should be inspected rather than assuming the appliance itself needs to be replaced.

Can a clogged dryer vent cause a fire?

Lint is combustible, and restricted dryer vent airflow can contribute to overheating. Keeping the dryer exhaust system clear of excessive lint and obstructions is an important part of dryer maintenance and fire prevention.

Why are my clothes so hot when they come out of the dryer?

Unusually hot clothes can be a sign that heat isn’t exhausting properly through the dryer vent. A buildup of lint, a blockage, damaged ductwork or another airflow problem may be contributing to the issue.

Can birds build nests in dryer vents?

Yes. Exterior dryer vents can provide sheltered locations for birds to build nests. A nest can restrict airflow through the dryer exhaust system and should be properly removed.

Mite-E-Ducts can also install qualifying bird-resistant dryer vent products and offers a one-year Bird Free Guarantee when eligibility requirements are met.

Can you clean a dryer vent that exits through the roof?

Many dryer exhaust systems terminate through a roof rather than an exterior wall. The appropriate cleaning approach depends on the vent’s layout, length, accessibility and condition. Mite-E-Ducts technicians can evaluate the system and determine the appropriate cleaning method.

Can a dryer vent be installed incorrectly?

Yes. Dryer vents can have problems such as improper routing, damaged or disconnected sections, excessive vent length or other installation issues that restrict airflow. A professional dryer vent inspection can identify problems beyond lint buildup.

What causes odors to come from air ducts?

Odors within an HVAC system can have several possible sources, including accumulated debris, moisture, microbial growth, pests or other contaminants. Identifying the source is important because simply masking an odor doesn’t correct the underlying problem.

Does Mite-E-Ducts offer air duct treatment?

Yes. Mite-E-Ducts offers SoldaMist treatment as an additional service for qualifying applications. Ask the Mite-E-Ducts team whether treatment is appropriate for your duct system and situation.

The time required depends on the size of the home, number of HVAC systems, duct configuration and condition of the system. Mite-E-Ducts can provide more specific expectations based on information about your home and HVAC system.

Do I need to leave my house during air duct cleaning?

In most cases, homeowners do not need to leave simply because their air ducts are being cleaned. Your technician can explain what areas need to remain accessible and what to expect while the work is underway.

How should I prepare my home for air duct cleaning?

Make sure technicians can easily access the furnace or air handler and vents throughout the home. Moving furniture or personal items away from registers when possible can make access easier. Mite-E-Ducts can provide any additional preparation instructions before your appointment.
