Indoor pollutions from the air can aggravate human respiratory conditions, cause harmful human bodily irritations, sickness and even disease.
The air inside the building is up to five times more polluted than the outside air. That's because the building is an closed environment full of potential pollution sources.
There are three main potential sources of air pollution types:
1) Particulates like dust, cigarette smoke , dander, drywall dust and pollen.
2) Volatile Organic Compounds which are gases from chemicals(paint, hardwood floor coatings) that are released into the air by various household materials (insulation) and liquids (laundry detergent).
3) Bio-burden is the biological material in the air, dead or living . Living material (hair from pets, bed bugs) some can cause disease, dead material (human dead skin) can cause allergic reactions.
Tare it's No Secret - Indoor Polluted Air is the number one cause of respiratory illness, such as flu and colds viruses. Air duct cleaning is Doctor recommended and can be a tax deductible medical expense when accompanied by a Doctor's note.
Dirty ventilation systems can aggravate allergy and asthma conditions in persons of all ages but most venerable are the children and the older. A clean ventilation duct system can reduce energy costs in the summer and the winter.
There are several situations when duct cleaning could make sense. If you have a problem with water in your ducts, this may result in mold growth in the duct. In this situation, solve the water problem first, clean and disinfect the ducts where mold growth has occurred, and have the rest of the ducting system cleaned as well. In some cases, it may be necessary or more cost effective to simply replace the affected duct areas.
If you are moving into a newly constructed house, and have doubts about the diligence of the construction crew, duct cleaning can be useful. Drywall dust, fiberglass pieces, and sawdust have no place in ducts. Duct cleaning will also catch the odd occurrence where lunch bags or soft drink cans have fallen or been swept into ducting. For similar reasons, duct cleaning may be advisable for older houses following major renovations. If you are having trouble with furnace airflow, a duct cleaning could reveal significant blockages. Have the ducts cleaned before you embark on more expensive duct replacement or rerouting to solve an airflow problem.
Cleaning of furnace and air conditioning components (e.g. furnace fan blower, air conditioning coil, humidifier, furnace heat exchanger, etc.) has been shown to make some difference in duct air flow. If you look in the return air registers and see an accumulation of debris in the duct below, you may want to have it removed. CMHC research showed that return air ducts, which are relatively big and have slow moving air, are generally far dirtier than the supply ducts. For example, households with hairy pets or young children may find it necessary to inspect their return air ducts more frequently.
