Poor indoor air quality is often due to airflow problems with the air ducts. What causes restricted air flow and how can homeowners remedy the issue? We’ll go over the common causes and the solution. In most cases, an air duct cleaning is in order.
1. Air Leaks
Modern air duct systems consist of multiple sleeves screwed together. The section where they intersect isn’t always airtight, causing air to escape at the joints. This can be fixed by using a sealant or mastic specifically designed for air duct use.
2. Dirty Fan Blower
Air conditioners and furnaces have a fan blower that distributes air through the ducts. Dust accumulation on the blades compromises the fan blower’s ability to allocate air. The fan blower should be cleaned with every air duct and AC maintenance.
3. Dirty AC Evaporator Coil
The evaporator coil is located above the furnace in a central AC unit. The coil produces cool air by absorbing heat. The coil, however, loses its ability to perform this function as it collects dust. Be sure to clean the coil at least once a year along with the fan blower.
4. Not Enough Return Air
Air ducts draw in air from return vents. An obstructed return vent results in less air for the ducts to blow out to the supply vents. An inspector can determine if the return vents are the problem and whether they require a cleaning or an update.
