A home’s ductwork often harbors harmful contaminants and micro-organisms. These include pet dander, bacteria, pollen, mildew, and mold spores. These substances can be inhaled and aggravate asthma and other respiratory problems. A periodic air duct cleaning will eliminate these pollutants, improve indoor air quality and help your family live a healthier lifestyle.

The National Association of Air Duct Cleaners (NADCA) recommends a professional evaluation and cleaning of residential ductwork. A NADCA member will use the industry’s best practices to ensure your home’s ductwork is cleaned thoroughly and effectively.

Air ducts are important components of a home’s heating, ventilation and air conditioning system. They are also essential to your family’s health and comfort. Over time, a build-up of dirt, dust and other debris can cause the deterioration of the ductwork. This can lead to clogs, which require the system to work harder to keep the house at a comfortable temperature. This extra strain can increase the energy costs of your home.

Dirty ducts may also be an ignition source for fire. When lint, dust and other particles accumulate in the ductwork and are heated by the furnace, they can ignite and burn. This can be a fire hazard and put your family’s lives at risk. Air duct cleaning is an effective way to reduce the risk of fire by keeping lint, dust and other debris away from the vents.

Besides reducing the airborne pollutants, an air duct cleaning will also help your HVAC system operate more efficiently. A dirty ductwork forces the system to work overtime to heat or cool your home, which can lead to premature wear and tear and higher utility bills. By maintaining the proper airflow, your ducts will last longer and run more smoothly, which can save you money on your utilities in the long run.

In addition to air duct cleaning, your contractor will also inspect and clean the blower wheel, motor and housing. They will also sanitize the interior of the ductwork using disinfectants to kill any bacteria or micro-organisms. This step is especially important if you or someone in your household suffers from allergies or asthma.

Before the technician arrives, spend some time the morning of or night before (if you won’t have enough time on the day-of) clearing space around your HVAC system and all of the vents in your home. This might include moving furniture and relocating sensitive items. You should also inform your contractor of any areas that need special attention or consideration.

Depending on the size of your home, the whole air duct cleaning process can take between three and five hours. This will depend on the number of vents and ducts in your home, as well as how much debris is in the ductwork. A thorough cleaning by a NADCA member will result in a cleaner, more efficient and healthier home.
