Air Duct and Furnace Cleaning
    How are the ducts cleaned?
    Annonson's Air Broom practices source removal. The National Air Duct Cleaners Association (NADCA) and Environmental Protection Agency (EPA) recommend this method. We provide the option of using a truck based vacuum or a portable HEPA vacuum. Both vacuums are equally efficient.

    The source removal cleaning process consists of the following steps:
    1. We hook up an 8" hose to the plenum (where the ducts connect to the furnace). The hose is connected to our vacuum
    2. We then go around and cover or close all the registers in the home/business. This ensures that there is no dust released during the cleaning process.
    3. Next we engage our vacuum system running at the minimum of 2500 cfm; the vacuum system creates a negative pressure and suction in the ductwork. This begins to pull out all debris and deposits the debris directly into our vacuum.
    4. We then go to one register at a time and remove it. The larger pieces of debris such as construction materials are removed first. Then the smaller debris is forced into the main trunk line using 200 psi. of forced air from the truck mounted compressor. This process flushes each vent.
    5. Next we clean out the main trunk line. A high-pressure line with a Viper Air Snake agitator at the end is fed through the main trunk line. The air pressure and the attachments force the remaining dust and debris back into the vacuum.
    6. Then the furnace is thoroughly cleaned. This cleaning includes the air conditioner coil, A/C drain pan, burners, flue pipe, heat exchanger, force draft motor, pilot assembly, blower motor and fan blades. If needed the motors are oiled. A carbon monoxide test is completed with a digital Kane Mays SGA91 CO Detector and a detailed furnace inspection sheet is provided.
