The answer to 'average cost of air duct cleaning' is that the typical range can vary widely, but most homeowners can expect to pay between $300 to $500 for a standard residential air duct cleaning service. The final cost can be influenced by factors such as the size of the home, the number of vents and ducts, the level of contamination, and the specific services required.
It's important to get local quotes from reputable air duct cleaning companies, as prices can vary significantly based on your geographic location and the unique needs of your home. Some companies may charge by the square footage of the home, while others may have a flat rate or charge per vent. Additionally, any specialized services like mold remediation or sanitization will likely increase the overall cost.
