Cleaning Ducts and Vents
According to the EPA, dirty air ducts do not necessarily contribute to health problems. The dirt sticks to the stainless steel and is not necessairly circulated into the living space. However, if there are dust mites, mold, vermin, rodents, insects and other squatters taking advantage of the situation, then it's time to issue the eviction notice and clean the air ducts.
- Open the main supply and main return access panels on your furnace. If none exist, cut holes for the high powered commercial duct cleaning vacuum.
- Seal all vents in the home.
- Insert vacuum to access panels or holes into the furnace.
- Create negative pressure in the ducting system by turning the vacuum.
- Vacuum each duct in the house separately using vacuum hoses.
- Use air tools for stubborn debris.
- Call a professional exterminator to remove vermin, rodents, etc., if needed.
- When each vent is cleaned, re-seal the vent with power tools before moving on to the next vent.
- Clean the blower, coils and other components.
- Remove vacuum and seal holes created in step 1.
NOTES: According to the EPA, home and office appliances run cooler and have greater efficiency and longer life when periodically cleaned. It is advised to have your stove, fireplace and furnace evaluated for proper functioning to prevent fires and carbon monoxide poisoning.
Products are on the market to kill mold, bacteria and fungal growth following a thorough air duct cleaning. These products may be professionally applied or can be purchased. They are "blown" through the system using the reverse cycle of the vacuum. During the cleaning process, it is possible to seal the system to prevent dust from leeching into the living area. This optimizes functioning and efficiency of the system, and should be professionally applied. Biocides and sealents are not registered by the EPA for an internal air duct system.
