What this calculator estimates
It estimates air duct cleaning cost from supply vents, return vents, HVAC systems, square footage, stories, contamination level, access, duct type, register washing, blower or coil add-ons, documentation, timing, travel, and local labor.
Why quotes vary
Companies may price by vent, by HVAC system, by square footage, or by a minimum package. Costs rise when access is tight, ducts are delicate, a home has multiple systems, or the job follows renovation dust, pests, moisture, visible debris, or component cleaning.
Health and moisture note
Planning estimate only. Duct cleaning is not a medical treatment and cannot guarantee allergy relief, indoor air quality improvement, odor removal, mold remediation, pest removal, or energy savings. If there is moisture, mold, or pests, fix the source before cleaning or the issue may return.
How much does air duct cleaning cost?
Air duct cleaning cost depends on vent count, return count, HVAC system count, home size, stories, contamination level, access, duct type, local labor, company minimums, and whether component cleaning or documentation is included.
Is duct cleaning priced per vent?
Some companies price per supply register or return vent, while others use a flat package by HVAC system or home size. Ask whether the quote includes all supply vents, returns, trunk lines, registers, blower compartment, and accessible coil areas.
Does air duct cleaning improve allergies or health?
No reputable quote should guarantee health results. Duct cleaning may be appropriate for visible debris, pests, moisture, mold concerns, renovation dust, or certain system conditions, but it is not a medical service or a guaranteed air quality fix.
Should I clean ducts after renovation?
Post-renovation dust can justify inspection and cleaning, especially if vents were not sealed during work. The estimate should account for construction dust, register cleaning, access, and whether HVAC components need separate service.
Are sanitizer or biocide treatments included?
Usually no. Chemical treatments should be quoted separately, explained in writing, and reviewed carefully, especially for sensitive occupants or internally lined ducts. This calculator treats chemical treatment as a separate scope item.
Is this a final air duct cleaning quote?
No. It is a planning estimate for comparing written quotes. Actual pricing depends on inspection findings, duct layout, equipment, access, local labor, company minimums, contamination, and what the contractor includes in writing.
