Ductwork refers to the system of ducts (metal or synthetic tubes) used to transport air from heating, ventilation, and air-conditioning (HVAC) equipment throughout your home. Properly installed and well-maintained air ducts are a key component of indoor air quality and home comfort. 

Why it’s important to keep your HVAC ductwork clean? 

Home heating systems produce a small amount of carbon monoxide, a harmful gas that is normally transferred outdoors through your ductwork. If pipes and vents are clogged or obstructed, that gas could find its way into your home’s air and compromise your family’s health. 

Fortunately, simple routine ductwork maintenance can prevent any potential carbon monoxide leaks. A qualified service technician can perform a thorough inspection of your heating system and ensure all ducts are clean and unobstructed. And by scheduling preventative maintenance each year, you’ll also help keep your equipment operating at peak efficiency and avoid any emergency repairs later on.

Duct cleaning  

The position of the U.S. Environmental Protection Agency (EPA) is that “If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary.”  

A thorough duct cleaning done by a professional duct cleaner will remove dust, cobwebs, debris, pet hair, rodent hair and droppings, paper clips, calcium deposits, children’s toys, and whatever else might collect inside. Ideally, the interior surface will be shiny and bright after cleaning. Insulated fiberglass duct liner and duct board can be cleaned with special non-metallic bristles. Fabric ducting can be washed or vacuumed using typical household appliances.  

Duct cleaning may be personally justifiable for that very reason: occupants may not want to have their house air circulated through a duct passage that is not as clean as the rest of the house. However, duct cleaning will not usually change the quality of the breathing air, nor will it significantly affect airflows or heating costs.
