According to the Environmental Protection Agency, properly cleaning an entire system in an average-sized home may typically range in cost from $450 to $1,000. However, there are several factors that affect cost and time estimates:
the type of ductwork
number of crew members required
level of contamination
Beware of advertisements that have “whole house specials” for very low prices. Many of them only include only the main ducts and charge extra for the air handler, blower fans, coils, registers and cutting access. Upon arrival, many of these companies then up-charge to excessive amounts.
How long should it take to clean a typical residential HVAC system?
The amount of time it takes to clean a residential HVAC system depends on many variables such as the size of the home, the number of systems, the extent of the contamination and the number of HVAC cleaners performing the job. Ask at least two contractors to inspect your system and give you a time estimate for your particular system. This will give you a general idea of how long the job should take as well as an idea of how thoroughly the contractor plans to do the job.
