The answer to 'how much does duct cleaning cost' is that the cost can vary widely depending on several factors. Generally, duct cleaning for a typical home can range from $300 to $700, though the actual price will depend on the size of your home, the number of vents and ducts, the accessibility of the ductwork, and the level of cleaning required.
The cost is also influenced by the experience and expertise of the HVAC technician performing the work, as well as your location. Homes in urban areas or with complex ductwork may cost more to clean than simpler systems in suburban or rural homes. It's important to get quotes from multiple local HVAC companies to compare prices and services.
