Estimated Cost
$300 – $600
Estimated Duration
3-5 hours
Consider duct cleaning if you've recently renovated, moved into a new home, have pets that shed heavily, or notice excessive dust buildup.
Look for companies that follow NADCA (National Air Duct Cleaners Association) standards. They should use powerful vacuums and brushes to clean the entire HVAC system, not just the vents.
A thorough cleaning should include all supply and return air ducts, as well as the main trunk lines. Ensure the technician shows you proof of the work, like before-and-after photos.
Be wary of 'blow-and-go' services offering extremely low prices. Quality duct cleaning is a detailed process and typically costs a few hundred dollars for an average home.
While duct cleaning can improve air quality, it's not a magical cure-all for allergies or asthma. Ensure your HVAC filters are regularly changed and your home is generally clean.
Ask about what's included and excluded. Some services might charge extra for cleaning the furnace or air handler components, which are crucial for overall system hygiene.
Unless there's a specific issue (like mold, pests, or post-construction debris), most homes don't need duct cleaning more frequently than every 3-5 years, if at all.
