Hey all!
I’ve seen a few questions about duct cleaning and wanted to share a quick, professional take.
Duct cleaning can be helpful but it should be based on an inspection, not fear or advertising.
• Burning or dusty smells should always be checked.
A mild smell at first furnace startup is common, especially in newer systems. Strong, persistent, or unusual odors should always be inspected.
• Most ducts are cleaner than ads suggest.
The majority of dust lives in filters, on floors, and on vent covers. Good housekeeping and regular filter changes do more for air quality than duct cleaning alone.
• Pets shed and kids (also shed, somehow) - that’s normal.
More shedding means more frequent cleaning and filter changes, but it doesn’t automatically mean your ducts are dirty.
• Dust builds up quickly no matter what.
Even after a duct cleaning, dust starts settling again within days. That doesn’t mean there’s a problem — it’s just normal living.
• IAQ products can often help more than duct cleaning.
Higher-efficiency filters, whole-home humidifiers, and air cleaning systems can greatly improve comfort and air quality, but they should be chosen based on the specific needs of the home.
• Older homes may benefit more from duct cleaning.
Homes with past renovations, older ductwork, previous owners, smoking, pets, or years of construction dust are more likely to actually need it — especially if ducts have never been inspected or sealed properly.
