Since you seldom see your ducts most of the time (they are hidden behind gypsum board, floors, and seldom used rooms) it"s often a struggle to understand why they may need regular cleaning. However, the ducts in a home circulate air through them regularly that comes through the return vents; the air that enters the return vents contains debris, dust, hair dander, and other contamination. Over the span of a year, this debris will begin to build up along the inside of the ductwork, and after three years this contamination level is often enough to begin to create problems for your home, the quality of your air, and the furnace.
To fight the problems of contaminated ductwork, you should schedule regular duct clean-up. Every 3– 5 years is recommended, although some homes may need it more regularly. The job requires professionals with power vacuums and agitation equipment; it isn"t something you can handle yourself using a dyson and a broom
To protect your indoor air: Indoor air quality has been on the decline since home design created more effective insulation. Duct cleaning removes a major reservoir for air contaminants from inside a home, helping to keep it a healthier and more relaxed place.
To bring down your heating and cooling bills: Even the thin layer of dust that can start to accumulate in ducts after only a year is enough to create friction against the airflow from an air conditioner or forced-air heater. Heavy congestion in the ventilation ducts can mean a comfort system that costs a 33% more to run.
To keep your home clean: Here"s a shocking fact: a six-room property on average circulates 18 KG. Cleaner ducts mean a cleaner home.
