Dirty ductwork can compromise indoor air quality

Forced air furnaces and central air conditioning systems share the annual temperature control workload. Both the heating and cooling units rely on the ductwork to carry conditioned air to the various rooms. The ducts are the lungs of the HVAC system. They directly impact comfort, energy efficiency and indoor air quality. If you consider the dust that builds up on surfaces in the home and contaminants that become trapped in the HVAC air filter, it stands to reason that the duct system is also at risk of an accumulation of debris. Things like dust, pollen, pet dander, construction debris, bugs, webs and even decomposing rodents are some of the unpleasant surprises found inside the average duct system. There’s also the possibility of mold and mildew growth. Every time the furnace or air conditioner starts up, air passes through this network of pipes. Any harmful spores, bacteria or toxins are then picked up, spread throughout the home and breathed by occupants. A long list of severe health concerns have been directly linked to poor indoor air quality. Respiratory infection, headaches and flu-like symptoms are just a few. When there’s a buildup of debris within the ducts, it restricts airflow. The maximum amount of heated or cooled air is prevented from reaching the intended destination, forcing the HVAC system to run longer and work harder to achieve the thermostat setting. You’ll notice certain rooms are impossible to keep at ideal comfort levels. You’ll also notice higher monthly energy bills and face an increased number of HVAC repairs. It’s a good idea to have the ductwork professional inspected and tested every three to five years. Ductwork cleaning is a non-invasive process that effectively removes contaminants and optimizes performance.
