Air Duct Cleaning FAQs, answered by experts

If you avoid deep cleaning, it can lead to a slew of issues for your health and home. Mold and mildew can grow in damp areas of the home, such as bathrooms, kitchens, and laundry rooms, which can cause allergic reactions and even structural damage to your house. A buildup of grime and dirt can allow bacteria and germs to thrive. A dirty home can also attract pests such as cockroaches, ants, and rodents.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

Water accumulation can occur due to either leaks or condensation on or near cooling coils. It's crucial to inspect for leaks, perform necessary repairs, and ensure regular maintenance checks for your coils and drain pans. Be sure to empty the drain pans completely, as any standing water in the pan indicates that it is not functioning as intended.

Return air ducts should generally not be installed in rooms with high humidity, contaminants, or strong odors. This includes bathrooms, kitchens, garages, closets, attics, and furnace or boiler rooms. Placing vents in these areas can draw moisture, fumes, odors, and potentially hazardous gases like carbon monoxide into your HVAC system, which can damage ductwork, promote mold growth, and compromise your home's indoor air quality and safety. According to the International Code Council, there are some exceptions. For example, a return duct may be placed in a kitchen if it is at least 10 feet away from cooking appliances and serves only that room. Similarly, a garage can have a return duct if it is part of a dedicated forced-air system that only serves the garage. For optimal performance, prioritize installing return air vents in central locations and rooms with consistent temperature needs, such as bedrooms and living spaces. If you are unsure, consult a professional duct installer for guidance.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
