AC DUCT CLEANING

What is Air Duct Cleaning?

Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing. If not properly installed, maintained, and operated, these components may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for microbiological growth (e.g., mold) is increased and spores from such growth may be released into the home's living space. Some of these contaminants may cause allergic reactions or other symptoms in people if they are exposed to them.

Are there any health benefits that come from HVAC system cleaning?

Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.

Will duct cleaning reduce my electricity bills?

Research by the U.S. EPA has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems are less likely to break down, have a longer life span, and generally operate more effectively than dirty systems.

How much will it cost me?

Depending on the services availed, the size of the system to be cleaned, system accessibility, climatic region, and level of contamination the service provider will provide a estimate after inspection of the site.

How is it done?

Methods of duct cleaning vary among service providers, although standards have been established by industry associations concerned with air duct cleaning. Typically, a service provider will use specialized tools to dislodge dirt and other debris in ducts, and then vacuum them out with a high-powered vacuum cleaner.

Will you clean the entire system?

If you decide to have your heating and cooling system cleaned, it is important to make sure the service provider agrees to clean all components of the system and is qualified to do so. Failure to clean a component of a contaminated system can result in re-contamination of the entire system, thus negating any potential benefits.

Do I need a duct cleaning?

Knowledge about the potential benefits and possible problems of air duct cleaning is limited. Since conditions in every organization are different, it is impossible to generalize about whether or not air duct cleaning for your institution would be beneficial. You may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should occasionally be cleaned to avoid all potential air borne problems.

What to Expect From an Air Duct Cleaning Service Provider?

If you choose to have your ducts cleaned, the service provider should:

How to determine if the Duct Cleaner did a thorough Job?

A thorough visual inspection is the best way to verify the cleanliness of your heating and cooling system. Some service providers use remote photography to document conditions inside ducts. All portions of the system should be visibly clean; you should not be able to detect any debris with the naked eye.
