When it comes to the specifics, cleaning air ducts is not a do-it-yourself activity. It involves the use of tools such as a high-powered vacuum and rotary brushes, which you most likely do not have in your garage.
Your heating and cooling ducts are your home’s lungs. Clean air improves the performance of the ducts, just as it does your lungs. However, there is some disagreement over how clean your heating, ventilation, and air conditioning (HVAC) ducts should be.
According to the Environmental Protection Agency (EPA), tiny dust found in ductwork is less dangerous than chemicals released by cooking, cleaning, smoking, or even walking across the carpet. HVAC ducts, unlike bookshelves and furniture, are part of a sealed system and do not accumulate dust. Filters in the furnace and air conditioner restrict contaminants from entering the HVAC system. This is why changing your HVAC filters on a regular basis is your first — and best — line of defense.
If mold is growing on the sheet metal of your ducting, you may need to take further care. While you can’t see within the ducts, odors, damp filters, or wall insulation may indicate the presence of mold. An HVAC technician may discover mold in your ductwork.
In ducts, rodents, insects, and other vermin can become contaminated. This is a serious problem that requires immediate attention from specialists. The droppings and dander of vermin quickly create an unclean environment in your home.
When it comes to the specifics, cleaning air ducts is not a do-it-yourself activity. It needs the use of tools like a high-powered vacuum and rotary brushes, which you most likely do not have in your garage. An improper cleaning approach may also cause duct damage, prompting costly repairs.
