What You Should Know About Your Air Ventilation System
    Why do you need this?
    Over time dust, pet hair, fibers, pollens and various other airborne irritants accumulate in the furnace and throughout the duct system. Most of these particles pass through the air filter(s), hiding in the air duct system and air handling equipment. This build-up can reduce airflow up to 50%. The air ducts are breeding areas for bacteria and molds that cause many people to suffer from allergies or respiratory stress. This can also be a source of musty, stale odors. We recommend a vacuum duct/vent cleaning for improved air quality, allergy relief and a cleaner living area.


    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.


    How is the chimney cleaned?
    The area around the fireplace is completely tarped off. The technician places a ladder on the chimney to gain access to the flue. Then specially fitted wire brushes are used to scrub the flue down to the smoke shelf. Next the crownwash, flue tiles and brickwork are inspected. The technician then continues the cleaning from inside the home. The damper is removed from the firebox, which allows the smoke shelf and walls to be cleaned and inspected for damage. The damper is then reinserted and the debris from the firebox removed. Once the cleaning is finished the technician provides the customer with a detailed inspection list that specifies the conditions of the fireplace.


    How is the dryer vent cleaned?
    First the dryer ductwork is disconnected from the dryer. Then all the accessible debris from the dry duct is cleaned out. The lint trap will be cleaned from the front to the back of the dryer and then the ductwork is reconnected to the dryer. Next the vent will be cleaned from the egress using 200 psi of high-pressure air. Once all of the built up lint has been forced out of the vent, our technician will bag it up and dispose of the lint.

    Clogged dryer vents can be hazardous, as they reduce the effectiveness of the clothes dryer. The US Consumer Protection Agency estimates 15,000 fires per year are started in dryers and dryer vents. A clean dryer vent increases the life span of your appliance as well as reduces fuel costs. This will also shorten the drying time required for your clothing.
