Clean air ducts professionally
Short answer
Hire an NADCA-certified duct cleaner every three years; avoid '$99 special' offers, which typically use underpowered equipment or upsell unnecessary services.
Why It Matters
Dust, allergens, and rodent activity inside ducts circulate through every room. Cleaning removes contaminants the filter can't catch.
How to Do It
- Search for NADCA-certified duct cleaners in your area. NADCA certification means the company meets industry standards for equipment and technique.
- Decline quotes priced around $99 or advertised as flat-rate specials. These jobs typically use underpowered equipment or include pressure to add services you don't need.
- Before the appointment, clear furniture and obstacles away from all supply and return vents so the crew has unobstructed access.
- Ask the technician to note any signs of rodent activity, mold, or damaged ductwork while the system is open.
- After the job, confirm all vents and access panels are resealed, then run the system briefly to verify airflow feels normal.
