Duct cleaning—as defined by the EPA—is the cleaning of various heating and cooling system components of forced-air systems. Professionals commonly clean heating and cooling ducts, dryer ducts, and exhaust ducts. Duct types include rigid sheet metal, flexible nonmetallic material and fiberglass. Duct cleaning is available for all types of structures from single-story homes to multistory buildings. Several factors affect the cost.
Number of ducts
The overall number of ducts to be cleaned affects the total cost. Generally speaking, the more vents, the higher the price. For example, Miller’s Cleaning Services in Baltimore, Maryland, offers residential air duct cleaning for a base rate of $200, which increases depending on the number of vents to be serviced.
Per duct costs
While some cleaning companies charge a set rate, others charge per vent and have varied pricing depending on the type of vents and their accessibility. For example, David’s Chimney Cleaning Service in Springtown, Texas, offers the following prices per duct:
$25 per register/vent
$35 per return
$45 per indoor unit
- $75 per outside unit as needed
Some companies specialize specifically in cleaning dryer vents for residential and commercial properties such as hair salons, fitness centers and so on. HomeSafe Dryer Vent Cleaning in Frisco, Texas, charges $120–$180, depending on ease of access to the vent's initiation and termination sites as well as the length and complexity of the vent system.
Certain circumstances may increase costs beyond a company’s standard cleaning fees. According to HomeSafe Dryer Vent Cleaning, any of the following can result in additional charges:
Rodent, bird or nest removal
Minor vent or duct repair
Transition hose replacement
A new termination hood, including installation
- Miscellaneous add-on products
- Be wary of very low prices or people who work too quickly. Standard homes can take three or four hours for duct cleaning. Dryer duct services only typically take one or two hours.
