Before you even allow a technician into your home, ask the following questions:
- What is the cost?
According to the National Air Duct Cleaners Association (NADCA), a reputable company will charge $400 to $1,000 in a typical 2,000-square-foot house, depending on the services offered, the size of the system to be cleaned, system accessibility, climatic region, and level of contamination. Customers from Angies List paid an average of $460 last year.
- Which services are included in that cost?
Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts, the main unit, and registers, grilles and diffusers using specialized tools.
- Are there additional charges?
Additional services may be offered such as air duct disinfection and dryer vent cleaning. Depending on current offers and time of the year one or both of these services may be included in an air duct cleaning service.
- How much time should the service take?
According to Angie’s List a typical air duct cleaning on an average size house should take between 3-6 hours.
Beware of companies that advertise extremely low costs, such as whole house air duct cleaning for $45. Common sense tells us no professional service company is sending 1-2 technicians, a truck, and machines to a home for 3-6 hours for $45. Once you get a price, make sure you know what is included, what tools they plan on using, and how long the service should take.
