AC Duct Cleaning

 AC cleaning services have been available since the early 1900s. However, it was not until the 1980s that growing public concern for better IAQ led to an understanding of the importance of cleaning AC system components. Public awareness has increased ever since. Greater demand for AC cleaning resulted in dramatic growth for the AC system cleaning industry both for firms offering service, as well as those providing research and knowledge of AC system cleaning and its impact on indoor air quality and system performance.

 

 

Method of Work:

Duct cleaning is an integral part of solving indoor air quality problems. The EPA endorses source removal” techniques for cleaning ducts. These techniques utilize special vacuum equipment, brushes, and compressed air to agitate the dirt in the ducts.

Properly cleaning air ducts is not a quick job. It usually takes between five and ten minutes per vent opening, or a total of four to eight man-hours for an average house. The duct cleaner should use equipment recognized by the National Air Duct Cleaners Association (NADCA). This equipment portable negative air power vacuum equipped with HEPA filters. A reputable professional will use the correct equipment, take the required time to do the job right, not damage your system during the cleaning process, and clean both the ducts and air conditioner components.

Method Cleaning of Air Conditioning System

1.      Safety clothing / equipment required: overalls, safety boots, eye protection, gloves and correct respirators.

2.      Conduct Safety briefing. Discuss with the client’s representative to ensure all possible hazards are identified and reported immediately if assistance is required for the control of hazards.

3.      The air conditioning unit is turned off.

4.      AC duct cleaning processes in reducing the level of airborne particulate matter and certain bioaerosols in fiberglass board duct systems. Their are two method …

a. The contact method in which conventional vacuum cleaning of the interior ducts was

performed.
b. The air sweep method in which compressed air is introduced to the duct for dislodging

dirt and debris and are carried downstream through the duct and out the system by

vacuum collection equipment.

5.      An access hole is cut into the supply plenum and the flex duct from the HYPE M/c is connected to the plenum. The HYPE M/c is then turned on to create negative pressure within the supply ductwork.

6.      All of the grill and differs are removed and cleaned.

7.      Foam core boards are placed up to the supply vent openings. The air movement holds these boards up to the openings. This also increases the air movement in the ducts. All but one supply vent is covered. The open supply vent allows for the air to safely flow backward through the air duct system without creating adverse negative pressure.

8.      Starting from the furthest vent opening, each branch line is cleaned using nylon duct brushes, cable driven brushes, or forward air blast assemblies to loosen debris. The agitation tool causes debris to be quickly caught up in the air movement from the HYPE M/c. The process is then repeated at each vent opening. Once all the branch lines have been cleaned, the main pocket filter is cleaned.

9.      After the dust and debris is removed from the system, an lightly fogged throughout the air duct system. This product immediately kills fungus and bacteria that may be left in the system.

10.  The HYPE M/c is turned off.

11.  The plenum area above the air handler unit is manually cleaned with portable vacuum equipment.

12.  The access opening is securely closed. If the system is sheet metal, the proper gauge sheet metal is cut to size. Insulation is put in place if required. Mastic is applied to the patch opening. The patch is secured with sheet metal screws, duct tape, metal tape, and more mastic. If the system is made of duct board or flex duct, the ten-inch cut out is reinserted. The entire area is fastened with approved duct tape and metal tape to insure a proper seal.

13.  Finally, through video camera, we re-inspect the air duct system in order to verify its cleanliness. During, and after, the cleaning process, we encourage you to see for yourself the cleanliness of air ducts.

14.  The insulation in the air handler unit case is manually cleaned and then treated with fogger m/c to kill any residual mold, fungus, or bacteria. The blower motor is inspected and cleaned if necessary and accessible.

15.  Coil cleaning with the COIL CLEANER

Safe for use on indoor cleaning coils
Specifically formulated to attack and remove all organic deposits found on heat exchange coil
Will not damage heat exchange coils
No odors

The Coil is first cleaned using Vacuum. Coil cleaner is then sprayed on the coil (diluted 1:10 with warm water) and left on the coil for 20 minutes. Subsequently all the residue has to be washed off using a low-pressure washer.

16.  The vent covers are re-installed.

17.  The system is turned back on and inspected for proper airflow.
