Since you really don"t see your ducts most of the time (they are hidden behind drywall, flooring, and rarely frequented rooms) it"s often a struggle to understand why they may need regular cleaning. The air ducts in a house circulate air through them regularly that comes through the return vents; the air that enters the return vents contains dirt, dust, allergens, and other contamination. Over the span of a year, this debris will begin to build up along the inside of the ducting, 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 HVAC system.
To fight the problems of dirty ductwork, you should schedule regular duct cleaning. Every 3– 5 years is recommended, although some homes may need it more often. The job requires professionals with power vacuums and agitation equipment; it isn"t something you can handle yourself using a dust buster and a brush
To protect your IAQ: Indoor air quality has been on the decline since domicile design created more effective heat sealing. This heat sealing helps a household save energy, but it also restricts fresh air circulation that can remove stale air from the inside your home. Reduced indoor air quality can bring about an array of health troubles, most of them respiratory, and it is particularly harmful for people who suffer from asthma and allergies. Duct cleaning removes a major reserve for air contaminants from inside a home, helping to keep it a healthier and more comfortable place.
To reduce 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 property clean: Here"s a startling fact: a six-room home on average circulates 40 lbs. of dust through its ventilation system every 12 months. Try to imagine that much dust spread over your home furniture! If your residence is filled with dust no matter how much effort you put in to keep it clean, a clogged ductwork system is undoubtedly contributing to the trouble. Cleaner air ducts mean a cleaner property.
