HVAC Cleaning: Your Path to Better Indoor Air Quality

By Chuck Henrichsen on February 8, 2016


Ductwork is every bit as important as your furnace or heat pump.

Dirty ductwork got you down? Fortunately, there's a straightforward solution: Ductwork/ HVAC cleaning. Contaminated ducts can cause several problems, not the least of which is poor indoor air quality. But, with the right equipment and a reputable team of pros, you'll get clean ducts and a cleaner home in just a few hours.

Here's what to expect:

The HVAC Cleaning Process

Ductwork cleaning professionals use specialized tools that improve on any cleaning that you could perform on your own. Some technicians use a high-pressure air hose to clean out the network of ducts and registers. Others use a vacuum with a brush attachment. The vacuum should be either located outdoors or have a HEPA filter if it's inside the home.

Not only are the ducts cleaned, but in many cases the whole system, including the blower fan and heating coils, gets a thorough vacuuming. After cleaning, the technician can fog the system with a disinfectant to eliminate any lingering traces of mold and dust mites. You should also expect an inspection that reveals problems such as duct leaks and damage.

Why Air Quality is Connected to Ductwork

Home Advisor says that while not every home needs routine duct cleaning, many do. That's because where a problem exists, indoor air quality suffers.

When an excess of dust exists inside the ductwork, dust particles blow into every room with a register when the HVAC system cycles on. Allergy sufferers and people with asthma are at a heightened risk from the effects of dirty air. If there's mold in the ductwork, the health of everyone in the home is at risk.


Regular filter changes can't protect your HVAC system from every contaminant.

Enjoy Cleaner, Better-Smelling Indoor Air

Have you ever noticed a stale, stagnant odor when you first turn on the HVAC system for the season? That's partly because of stale, dusty air in the ducts and partly from a dirty HVAC unit. A filter-mounted air freshener only masks the problem, the same way that a spray can of air freshener perfumes, but doesn't clean, the air.

After ductwork cleaning, you're much less likely to notice any odors, and allergy and asthma sufferers should experience fewer symptoms. Your home will stay cleaner, too. Regular filter changes remain important going forward to reduce the amount of contaminants that collect inside the system. What you may not realize is that no filter is failsafe. Some filters are better than others. Even the best HEPA filter can't capture every particle.

The U.S. Environmental Protection Agency lists central heating and cooling systems as a known source of indoor air pollutants. Particles might include ordinary dust, dust mites, mold, and many other pollutants. If you've done any interior renovation, even more pollutants, including lead and asbestos dust in an older home, can migrate into the HVAC system and ductwork.
