Learn the Basics About Your Home’s Air Ducts


No matter how efficiently your furnace and air conditioner operate, a home’s heating and cooling system can only reach top efficiency when air ducts are in good condition. Staying on top of duct maintenance helps you stay comfortable and control your energy bills throughout Massachusetts’ snowy winters and humid summers.

Your home’s ductwork is a system of sheet metal, fiberglass and flexduct that carry air from the furnace, heat pump or air conditioner to each of your rooms. They’ installed in walls, floors, basement, and/ or attic, depending on your home’s design.

To ensure high indoor air quality and sufficient air supply, the ducts should be clean and free of obstructions. The system shouldn’t leak more than 10 percent of the air it carries.

Keep Your Ducts Safe and Efficient

Points where the air ducts connect to the air handler, registers and vents, as well as to each other should fit securely and be sealed with mastic or foil-backed tape. Ducts in unconditioned spaces should be covered in duct wrap or batt insulation.

While a duct system can stay clean for years, regular professional inspections help catch problems before they do much damage. Every two years or three years, have your home’s air ducts inspected for mold growth, pest infiltration, dust buildup and other debris. Duct inspections are also recommended after you move into a new home, after remodeling, and if you’ve noticed pest debris or patches of  possible mold in or around your ducts.

Dirty ducts can release contaminants into your home’s air. Debris buildup interferes with airflow and gums up the HVAC system’s motor and other components, reducing energy efficiency and potentially leading to early component failure.

A heating and cooling professional can inspect sections of the ductwork you can’t easily reach, spot any problems, and let you know if cleaning, repairs or upgrades are recommended.
