HOME VENTILATION CLEANING SERVICES
The Environmental Protection Agency (EPA) estimates indoor air could be two to five times more polluted than outdoor air. The National Air Duct Cleaners Association (NADCA) has also estimated that on average every year air ducts in a six-room house collect 40 pounds of allergens, dust, and dirt. Our website gives you plenty of information to educate you before you get your air ducts cleaned.
Our Cleaning Process
There are two key components to air duct cleaning: breaking contaminants loose and the collection of contaminants. We use these methods in our 12-step cleaning process to properly clean your duct system.
Breaking Contaminants Loose
Properly cleaning HVAC systems requires removing the sources of contamination. Source removal begins with the use of one or more agitation devices designed to loosen contaminants from the surfaces within the heating and air-conditioning system.
Examples of agitation devices include brushes, air whips, and compressed air nozzles, or “skipper balls.” Agitation can also be achieved through hand-brushing or contact vacuuming.
Collection of Contaminants
During cleaning, the entire HVAC system is placed under continuous negative pressure (vacuum) to prevent the spread of contaminants. The continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning.
This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.
Home Duct Cleaning
(The procedures listed below are our typical procedures for residential duct cleaning. Some residential duct systems will require more attention or need added steps to complete our full comprehensive duct cleaning.)
We go to each register and vacuum register boots with a HEPA vacuum. Floor vents will tend to have objects that have fallen inside the boots throughout the years (i.e. screws, toys, animal hair, etc…). We vacuum those larger objects before we turn on our negative air and pass them through your air duct system.
Depending on the type of ductwork, a power brush system may be used to mechanically brush inside your ducts to agitate loose dirt, where possible.
All of our equipment has been extensively tested and approved by the NADCA (National Air Duct Cleaners Association). We take pride in providing the best service possible and ensure we have the best equipment possible.

Minor Ventilation Repairs
1. On some occasions after cleaning, there remains a thin film of hardened dirt at the bottom of the ducts that we cannot extract. This film is stuck to the air ducts due to its hardening from moisture build-up over time. We will help combat this film by fogging a botanical anti-microbial solution, Decon 30, at an additional cost.
2. If during the process of cleaning the vents, the technician determines there is an obstruction or unsafe bend in the duct, the technician will only proceed to what is deemed safe in an effort to avoid perforating the duct lining. No forcing of equipment will be done.
