HVAC duct efficiency is directly related to household comfort, healthy indoor air quality, and monthly operating costs. The consistency of warm airflow throughout the entire house, in the proper volume to accommodate the heating requirements of all rooms, doesn’t happen by accident. When any of the common factors associated with duct efficiency aren’t up to specifications, you’ll feel it on cold winter days and pay for it when the heating bills arrive each month. Here are some of the common air duct issues that may occur in winter:
A Clogged Filter
It’s basic: If your air filter isn’t replaced regularly, airflow throughout system ductwork is reduced. Your furnace runs longer cycles to maintain thermostat settings and keep the house warm. Costs increase; meanwhile, comfort and indoor air quality decline. All winter long, change the HVAC air filter at least every other month.
Over time, loose joints and gaps developing in ductwork spill heated and cooled air into zones such as the attic or crawl space. This loss of conditioned air means temperature control becomes increasingly inconsistent. It also results in steadily rising costs. In some houses, loss due to duct leakage exceeds 50% of the total air volume produced by the furnace or A/C. If your home is more than 10 years old, schedule a duct inspection with a qualified HVAC contractor to determine the extent of leakage and, if necessary, consider sealing options to restore full ductwork function.
When an HVAC system is installed, the airflow volume is balanced to accommodate the size of each room. However, if duct airflow is insufficient due to issues such as obstructions or deterioration, blocked or closed supply or return vents, or an internal damper that isn’t properly adjusted, airflow balance throughout the entire house can be affected. Some rooms may receive too much warm air, while others get too little. An HVAC service technician can check output at all vents and take corrective measures to restore airflow balance and efficiency.
