Air Duct Cleaning

Clearing the air

As part of an overall plan for respiratory health, a professional air duct cleaning can serve to remove unwanted irritants and harmful substances from the air conditioning or heating system of a home.  In addition to ensuring adequate ventilation and reducing exposure to harmful airborne pathogens and toxins, air duct cleaning can help improve health, combat the accumulation of allergens, and reduce symptoms in those who suffer from respiratory ailments.  The Environmental Protection Agency recommends air duct cleaning to remove particles, dust, and mold as needed.

How do I clean my air ducts?

The right tool for the job

Duct cleaning involves the industrial cleaning of the various components of forced air systems, including the supply and return air ducts, registers, diffusers, heat exchangers, coils, condensate drain pans, fan motors, fan housings, and the air handling units.  During normal usage, particles of dust, pollen or other debris can accumulate inside the system.

Furthermore, if moisture is present, conditions could promote the growth of microbes, bacteria, or mold.  These organisms could release spores, fumes, or other harmful materials into the air inside the home.  Particularly harmful to people who suffer from asthma, emphysema, allergies, or other respiratory ailments, these substances could make even otherwise healthy people ill.

A qualified, professional service provider will make certain to identify and clean every part of the system. Failure to clean any component of a contaminated system could result in re-contamination of the entire system, thus negating any potential benefits.

Methods of duct cleaning vary, but industry associations have developed standards. Typically, a service provider will use specialized air duct cleaning equipment to dislodge dirt and fungus, and then vacuum with a high-powered cleaner.  Since many parts of the system can be inaccessible, it is important to choose a competent, knowledgeable service provider, one familiar with your particular system.  Some services recommend treating ducts with sealants or biocides, both of which can significantly alter the air quality inside your home.  An expert duct cleaner can develop a targeted, unique plan specialized for your exact needs.
