How Much Does Air Duct Cleaning Cost in New Jersey? (2026)

For an average single-family home in New Jersey with one HVAC system, a thorough air duct cleaning runs roughly $450 to $850 in 2026. Larger homes, multiple systems, or heavy contamination push that range higher.

Anything quoted below $200 is almost always the start of a bait-and-switch. The crew arrives, 'discovers' issues, and the real number lands two or three times higher.

The biggest cost drivers are the number of supply and return vents, the number of air handlers, and whether the coil and blower wheel are cleaned. A real cleaning includes all three.

• Number of vents (supplies + returns)
• Number of air handlers / furnace units
• Coil and blower wheel cleaning included
• Accessibility of the equipment
• Level of contamination (post-renovation, pets, mold)

A trustworthy quote spells out exactly what's cleaned, uses a single flat number, and does not depend on what the technician 'finds' on site. Ask for it in writing before booking.
