How much time does it take to clean the air ducts in my home?

It depends how dirty the ducts are and what type of cleaning you are looking for. Again the location of your house also matters and how much area you want us to clean. The typical single-family home’s air duct system takes between 2 to 4 hours to clean with a crew consisting of at least two technicians. Older homes and those with pets may take longer to clean. Newer homes, townhomes and condominiums may take less time to clean.

Does the cleaning process make a mess in our home?

No. Our technicians are equipped with the highest quality and most state of the art duct cleaning equipment. All vacuum devices used in our process utilize HEPA (high efficiency particulate air). This filtration is rated at 99.97% at .3 microns.

Are chemicals used in the cleaning process?

No. Chemicals are not used unless required by an industrial hygienist or a certified restoration contractor. In the event chemicals are required to perform a project Fox Duct and Exhaust Cleaning will only use an EPA registered anti-microbial solution. MSDS (material safety data sheets) are available upon request. Application of a mild non-toxic anti-microbial solution may be ordered at an additional charge. If microbial growth is identified or suspected, application of these chemicals is not recommended as part of a routine maintenance program.

Do you have to cut any holes in the ductwork?

Yes. We typically have to cut two holes per system in order to clean it properly. One hole will be cut on the supply plenum as close to the furnace/air handler as possible. The second access is made on the return duct near the filter rack/section. All service access covers will be installed in accordance with NADCA and SMACNA standards. After cleaning is done you may notice small one inch round grey colored cap plugs. These plugs are used to seal cleaning access points throughout the system and do not affect the system performance.
