When to consider duct cleaning
Homeowners know that maintenance is vital to protecting their home and their investment in it. A well-maintained home is both a point of pride and a sound investment.
Home maintenance can improve the look of a home, and such efforts also may help to make spaces healthier for residents and guests. Duct cleaning is a home maintenance task that homeowners look to with the intention of making interior spaces healthier. The United States Environmental Protection Agency notes that duct cleaning has never been shown to prevent health problems, but the EPA nonetheless advises homeowners to consider duct cleaning if certain conditions are present.
• Mold growth: The EPA notes a duct cleaning may be necessary if there is substantial and visible mold growth inside hard surface ducts or on other components of a heating and cooling system. Mold growth can be difficult to confirm, as much of the heating and cooling system will not be visible. If an HVAC technician reports the presence of mold, ask that a sample be analyzed at a lab, which the EPA notes is the only way to confirm the presence of mold. The EPA estimates the cost to analyze a sample is roughly $50.
• Presence of vermin: Rodents and insects in the ducts are a notable problem that needs to be remedied. A duct cleaning should be a component of vermin remediation, as rodents can leave feces in ducts, which may look like small brown pellets.
• Dust and debris accumulation: The EPA notes that dust and debris that accumulates in the ducts can clog them. This also can lead to dust, debris and particles being released into the home through the vents.
Duct cleaning can be part of the solution when homeowners are confronting certain conditions, including mold growth, vermin infestation, and excessive accumulation of dirt and debris. But the EPA notes it’s important that the underlying cause is addressed to prevent future issues.
