Why Should You Get Your Air Ducts Cleaned?

Answer: Because They Get Dirty!

In addition to normal accumulations of dust and dirt found in all homes through regular use, there are several other factors that can increase the need for air duct cleaning:

  • Pets
  • Occupants with allergies or asthma
  • Cigarette or cigar smoke
  • Water contamination or damage to the home / HVAC system
  • Home renovation or remodeling projects

Some occupants are more sensitive to these contaminants than others. Allergy and asthma sufferers, as well as young children and the elderly tend to be more susceptible to the types of poor indoor air quality that air duct cleaning can help to address.

Proper HVAC cleaning process

There are two key components to HVAC cleaning: breaking contaminants loose, and collection of contaminants.

Breaking Contaminants Loose
Breaking Contaminants Loose

Properly cleaning HVAC systems requires removing the sources of contamination. Source removal begins with use of one or more agitation devices designed to loosen contaminants from the sur faces 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
Collection of Contaminants

During cleaning, the entire HVAC system is placed under continuous negative pressure (vacuum) to prevent the spread of contaminants. 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 ser ves to extract the loosened contaminants, which are collected and removed from your home.
