Your ductwork plays a big role in your home’s comfort—but over time, it collects dust, pollen, dander, and even mold. That buildup doesn’t just affect your air quality. It can also strain your HVAC system and drive up energy costs.
Since most ducts run through areas like crawlspaces, attics, or behind walls, they’re easy to forget about. But if you’ve noticed more dust around your home or worsening allergy symptoms, it might be time for a cleaning.

WHY IT PAYS TO
KEEP YOUR DUCTS CLEAN
Over time, airflow can slow down as dust and debris build up inside your system. That makes your HVAC unit work harder, which increases energy use and shortens the lifespan of your equipment.
A proper cleaning clears out those blockages, so your system can do its job more easily—and more efficiently. For families with asthma, allergies, or general air quality concerns, this service offers serious relief.
We help reduce the dust, pollen, and bacteria circulating through your home, so the air you breathe stays clean and comfortable.
Additionally, some homeowners have allergies, asthma, or other sensitivities to air quality, or have families with air quality sensitivities. For those with these conditions, it’s important to keep the air in the home as clean and healthy as possible.
Professional duct cleaning helps remove harmful contaminants like bacteria, dust, debris, dander, and pollen. As a result, you can maintain a higher quality of fresh air in your home.

FAQ
HOW OFTEN SHOULD YOU CLEAN AN HVAC SYSTEM IN LYNNWOOD, Washington
Every home is different. But NADCA recommends a cleaning every 3–5 years. If you have pets, allergies, or notice a lot of dust, you may need it more often.
HOW DO YOU CLEAN AN HVAC SYSTEM?
The best way to clean ducts and ventilation systems is by using the Source Removal method to clean your system. You need an air duct cleaning contractor in LYNNWOOD, WA for this job. We use a special, high-power vacuum that places negative pressure on the system.
Our professional vacuum sucks air through the system while devices are fed through the ducts to knock debris loose from the interior surfaces. Once loose, the debris runs down through the air ducts until it hits the vacuum, leaving your system and your house clean.
HOW LONG DOES AN HVAC AIR DUCT CLEANING USUALLY TAKE?
The duration of duct cleaning can vary greatly depending on a few major factors. Things like the size of your home and when your last duct cleaning took place, will determine how long your air duct cleaning service will take.
Typically, homeowners can expect the process to take about two to four hours. If you would like a custom time quote, feel free to reach out to Capitol Duct.
HOW DO I CHOOSE A GOOD AIR DUCT CLEANING CONTRACTOR?
While there are good air duct cleaning companies available, we recommend a few things to look for when shopping around.
First, find an experienced local company with great reviews, offering transparent pricing and a guarantee. Specifically for air duct cleaning, find one that is a member and in good standing with the NADCA. Additionally, you’ll want a licensed and insured company who comes highly recommended by neighbors, family and friends.
HOW MUCH DOES RESIDENTIAL AIR DUCT CLEANING COST?
In most cases, homeowners find themselves paying between $450 and $1,000. The price often depends on things like the size of your home, the degree of contamination, how accessible your system is, and duct materials.

HOW DO YOU KNOW IF THE AIR DUCT CLEANING ACTUALLY WORKED?
The best and most obvious way to tell if your air duct cleaning worked is by visually checking before and after the job is completed. If there is any visible sign of debris or dust in the ducts after the vacuum is done, then the cleaning is not considered complete. We have tools available and will help you inspect things. A final cleaning checklist should always be followed to make sure your ducts have been thoroughly cleaned.
