The duct system in your home functions as the respiratory
system. When it becomes contaminated and congested,
it should be cleaned so it can 'breathe' normally and
efficiently.
Dust, dirt, pollen, animal dander and other airborne
contaminants are pulled into your duct system every
time the furnace or air conditioner runs. These contaminants
build up inside the duct work over time and can help
make your duct system an ideal breeding ground for mold
spores, bacteria, fungus, mildew and other microbes.
Family members who suffer from allergies, asthma or
other respiratory ailments as well as children and the
elderly are especially vulnerable to the effects of
indoor air pollutants.
NADCA Quality Assurance Check List for Residential
Contractors:
- Can the company show proof of NADCA membership
and certification?
- How long has the contractor been in the residential
HVAC system cleaning business?
- Can the contractor provide you with evidence of
the current Worker's Compensation and General Liability
Insurance coverage? (Ask for Certificate of Insurance)
- Does the contractor posses the proper Licenses
that are required by your city or state to perform
the work they are proposing? (Not all cities or states
require licenses.)
- Will the contractor provide you with 3 to 5 customer
references with phone numbers for whom they provided
service in the last 30 days?
- Will the contractor conduct a thorough inspection
of your system PRIOR to performing any work and alert
you to any problems? This is required by the current
NADCA Assessment, Cleaning & Restoration of HVAC
Systems (ACR) Standard.
- Will the contractor provide you with a means to
conduct a visual inspection at any time during the
cleaning? (Mirror and flashlight, camera or other
remote visual systems.)
- Will the contractor be cleaning the complete system,
including coils and fans?
- Will the contracting company actually do the work?
(Some companies subcontract the work to independent
contractors. You will want to apply these guidelines
for subcontractors as well.)
- Is the contractor giving you a guaranteed price
before the inspection?
This may expose you to extra costs. Finding mold in
the system, damaged fiberglass insulation, cleaning
or treating cooling coils may become add-on costs.
