Mold needs three things to survive: Moisture, Nutrients (such as
dirt, dust, animal dander, cellulose construction debris from building),
and a Surface to grow on. Your ductwork can become an unknown breeding
ground for fungi, germs, and mold.
Studies have confirmed that contaminated air ducts spread some disease,
including salmonella, strep, and legionnaires disease.
The Environmental Protection Agency claims that indoor air has been
found up to 70 times more polluted than outdoor air. We spend 60% to
90% of our time indoors.
Better Health Magazine states “1 out of 6 people who suffer
from allergies do so as a direct result of the fungi and bacteria in
the air duct systems.”
Reduced energy bills? Research by the EPA had demonstrated that HVAC
system cleaning may allow systems to run more efficiently by removing
debris from sensitive mechanical components. Clean, efficient systems
generally operate more efficiently than dirty systems.
3. What criteria should I use in selecting a HVAC System
Interview as many local contractors as you can. Ask them to come to your
home and perform a system inspection and give you a quotation. To narrow
down your pool of potential contractors, use the following pre-qualifications:
Make sure the company is a member in good standing of the National
Air Duct Cleaners Association (NADCA).

9. 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.
A typical 2,000 sq. ft. home averages 4-5 man hours to complete the cleaning.

duct cleaning service?
The Environmental Protection Agency says that “duct cleaning services
typically – but not always – range in cost from $450 to $1000
per heating and cooling system, depending on the services offered, the
size of the system to be cleaned, system accessibility, climactic region,
and level of contamination” and type of duct material.
Consumers should beware of air duct cleaning companies that making sweeping
claims about the health benefits of duct cleaning – such claims
are unsubstantiated. Consumers should also beware of “blow-and-go”
air duct cleaning companies. These companies often charge a nominal fee
and do a poor job of cleaning the heating and cooling system. These companies
may also persuade the consumer into unneeded services with and/or without
