The problem behind Air Duct Mold Cleaning
Ducts that run through attics, crawl spaces and cold basements can sweat on the outside and inside. Insulated flex duct can collect water at low points. Growth inside a duct is hard to see, but odor at the vents or dark spots on registers can give it away.
Where Air Duct Mold Cleaning fits in Boston
Many Boston homes have ducts retrofitted through attics and basements. A long duct in an unheated space can condense water in humid weather, and older metal duct joints may leak, drawing damp air into the system.
What Air Duct Mold Cleaning covers
- Inspecting vents, registers and accessible duct sections
- Sealing registers and creating negative pressure for the cleaning
- Agitating and vacuuming duct interiors with HEPA equipment
- Removing or replacing insulated duct that cannot be cleaned
- Looking for moisture sources such as leaks and condensation
How the work proceeds, step by step
Inspect registers and runs
We look at registers, accessible duct sections and areas where condensation could form.
Set up negative pressure
A HEPA equipped vacuum creates airflow toward the work so debris is captured.
Agitate and vacuum
Brushes loosen debris from duct walls while the vacuum draws it out.
Replace damaged sections
Wet insulated flex duct is usually removed rather than cleaned.
Seal and find the source
Leaks and condensation spots are noted so moisture does not return.
Good to know before you call
Routine dusty ducts are a different matter from moldy ducts. Not every duct needs cleaning, and we will say so if the problem lies elsewhere, such as a damp air handler or a leaking roof.
Replacing a contaminated flex duct is often more reliable than trying to rescue it. Fiberglass lined ducts that have been wet are especially hard to clean thoroughly.
Questions about Air Duct Mold Cleaning
Is air duct cleaning needed every year?
Not necessarily. It is appropriate when there is visible growth, moisture or a persistent odor from the system.
Can you clean all the ducts?
Accessible ducts, yes. Hidden or damaged sections may need access panels or replacement.
