Duct cleaning or Ventilation cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems. These include the supply and return air ducts and registers, grilles and diffusers, heat exchangers, heating and cooling coils, condensate drain pans (drip pans), the fan motor and fan housing, and the air handling unit housing.
Consider having your ducts cleaned if you have:
A newly constructed house to remove all the debris that could have fallen into the vents during construction.
An existing building that has been remodeled or was under construction.
Purchased a house or building and don’t know if the ducts have ever been cleaned.
Lived or worked in your building for more than 5 years and have never had the ducts cleaned.
Do you have an Indoor Air Pollution problem?
Do you have an air circulating system that utilizes a standard fiberglass filter?
Do you have pets?
Are there smokers in the building?
Does any of the people in the building suffer from allergies, asthma, or other respiratory problems?
Do you regularly clean excessive dust accumulations?
Do you experience headaches nausea, burning sensations in the nose, throat, or eyes when inside the building?
Do you have dust trails or discoloring coming out of your air duct registers?
When you last changed your furnace filter, did you see dust and dirt inside the filter housing?
If you answer “yes” to any of these questions, you may have Indoor Air Pollution.
What to Expect From an Air Duct Cleaning Service Provider
Open access ports or doors to allow the entire system to be cleaned and inspected.
Use vacuum equipment that exhausts particles outside the home, or we may use High-Efficiency Particulate Air (HEPA) vacuuming equipment if the vacuum exhausts inside the home.
Protect carpet and household furnishings during cleaning.
Use well-controlled brushing of duct surfaces in conjunction with contact vacuum cleaning to dislodge dust and other particles.
Use only soft-bristled brushes for fiberglass duct board and sheet metal ducts internally lined with fiberglass. Flex duct can also be cleaned using soft-bristled brushes or an air whip connected to an air compressor.
Remove, clean, and reinstall all registers and vents.
Take care to protect the duct work, including sealing and re-insulating any access holes the service provider may have made or used so they are airtight.
