Factors to Consider When Estimating Cost
We recommend obtaining multiple air duct cleaning price quotes and discussing with each business what they plan to accomplish throughout the cleaning process. The following are the factors that influence air duct cleaning costs:
Size of Ductwork
The cost of air duct cleaning is determined by the size of the duct and HVAC. Professional air duct cleaners usually charge by the vent or by the square foot. Cleaning ducts cost between $25 and $50 per vent. The HVAC system is connected to each room through ducts through each vent. It will cost between $0.15 and $0.25 per square foot if the professional charges by the square foot. Cleaning an HVAC system might cost anywhere from $300 to $700 on average.
Number of Furnaces & Air Conditioning Units
The more furnaces you have, the higher your costs will be. Each extra heater and ducting installation will cost around $400 on average. Although uncommon, you’ll frequently encounter this in homes with additions where the original furnace was incapable of heating the addition as well.
HVAC Mold and Mildew Removal
$600 to $2,000 for skilled mold removal on top of the regular cost of cleaning the ducts. Removing these components takes more time, requires specific equipment, and even requires special chemicals. If the mildew and mould are serious enough, you may be sent to a professional.
Residential vs. Commercial Duct Cleaning Cost
Residential duct cleaning is less expensive than commercial duct cleaning. While home services may cost $20 to $40 per vent, commercial projects cost at least 30% more and cost at least $35 to $50 per hour. Because businesses differ, you’ll need a quote to determine how much you’ll pay.
