Frequently Asked Questions

Q.  Why does my system need cleaning?
A.  Dust is made up of dirt, pollen fibers, mold spores, hair and other allergy causing particles all of which get drawn into your HVAC system.  About 95% of these particles will pass through your filter and back into the room or they will accumulate on the fan blades of the blower motor, the grills, or the inside of your duct work.  The build-up of dust not only reduces air-flow it also can cause allergic reactions for allergy sufferers, and leave your house with a musty odor. 

Q.  How do I know my system needs to be cleaned?
A.  Take a moment to ask yourself these questions:

• Does anyone in your family suffer from headaches, nasal congestion or sinus problems in the morning or at night?
• Is there a smoker in the house or has a smoker ever lived in your home?
• Do you have dogs, cats or other pets or have pet owners ever lived in your home?
• Does your furniture get dusty again shortly after it has been cleaned?
• Is your furnace equipped only with a standard throw-away fiberglass filter?
• Does it seem like there is not enough air flow coming from your vents?

If you answered YES to any of the above questions, then it may be time to consider having your air duct system professionally cleaned! Air ducts are the lungs of a building and over time, dirt, dust, debris, tobacco smoke, animal hair/dander and other contaminants can accumulate inside the duct work. Dirty ducts can also become an ideal breeding ground for pollen, mold spores, mildew, bacteria, and other potentially harmful bio-pollutants which can pass easily through the furnace filter and into the air you and your family or co-workers breathe.

Q.  When should duct work be cleaned?
A.  When anyone in the house has a breathing problem such as asthma, allergies or emphysema.  If there are indoor pets.  Before moving into a new home.   When installing a new furnace.  After any renovation work has been completed.   And whenever dust appears on walls, floors, ceiling fixtures, carpets, drapes or around registers.

Q.  How often should they be cleaned?
A.  In most homes and businesses the duct work should be cleaned every three to five years.

Q.  How are they cleaned?
A.  Air Quality Systems uses equipment especially designed for duct work cleaning. 

• We locate gasoline powered vacuum equipment close to your system to maximize air pressure. Once the vacuum is attached to your system, debris in the ductwork is loosened and removed by a combination of reverse air and rotating nozzles, brushes, and whips with 180 lbs of applied air pressure.
• The vacuum then pulls the loosened debris, dust, and mold into a specially sealed compartment at 6000 cubic ft per min. 
• Heating and Cooling coils are then thoroughly cleaned as necessary with detergents and hand washed per NADCA standards. 
• The HVAC fan housing and blower units are cleaned with vacuum and compressed air, then pressure-washed as necessary.
• And finally, ….all supply and  return registers are cleaned.

Q.  What benefits can I expect?
A.  Many of our customers (even those without allergies) report that they no longer wake up with stuffy heads.  Allergy sufferers may find relief from sneezing, runny nose and watery, itchy eyes.  The dust level in the house is reduced, musty odors are gone and air flow is increased up to 40%.  Heating and cooling costs could be reduced.  And most importantly your family will breathe cleaner air!

Q.  Should I clean just the ductwork?
A.  Actually the entire HVAC system should be cleaned. By cleaning all components of the system you can reduce the risk of re-contamination.  Air Quality Systems follows standards set by NADCA—(National Air Duct Cleaners Association) to ensure the complete system is cleaned.

Q.  What is a “complete system”?
A.  A complete system includes… Air ducts, Coils, Drain pan, Registers, Grills, Air plenum, Blower motor and assembly, Heat exchanger, and Air Filter and Cleaner.  (Please note that due to the many sizes of filters, Air Quality Systems does not stock or replace filters on your furnace.)
