The HVAC system and network of air ducts were visually inspected. The information in this report is private and shared only with the assigned designees of Douglas A. King Builders, Inc. (DAK). Interpretation of the data collected in this assessment is meant to inform DAK as to the condition of their HVAC system.
The work area consisted of a two-bedroom apartment with two baths, kitchen, living room and hallway. The residence has one air handler, (see specifications chart 1 ). There was a total 12 registers, including returns. 400 feet of flex duct was cleaned as was 125 feet of main trunk. Multiple access points were used to allow for manual cleaning and to attach a negative air machine.
Containment Furniture, carpets, electronics and artwork throughout the space were covered with .3 mil plastic to prevent cross-contamination. Floor coverings and protective shoe-booties were used for an added layer of protection and sanitary awareness.
Vent & Registers: Twelve vents and registers were removed in order to accessed ductwork for manual cleaning. Registers were summarily cleaned and replaced in a pre-recorded order.
Main Trunk: The single AHU supply trunk was found to be sealed and was cleared of a large amount of visible debris which had a strong odor of cigarette smoke. The dust matter was nearly one-inch thick in some spots. The trunk was free of moisture or biological contaminants.
Ductwork: The ductwork was highly contaminated, but no bacterial growth. Smoke odor permeated the entire system. Multiple access points were used in both the supply and return plenums to attach a Nikro 5,000 CFM HEPA negative air machine. Interior of ductwork was cleaned using mechanically rotating brushes and a 20' flexible cable with a 12" silica brush (whip). One bath vent was inspected and cleaned. System remains at 100% efficiency and odors were neutralized by a NADCA approved neutralizing agent..
Air Handler: One forced hot air furnace was inspected, cataloged and cleaned. The system was in good working order with superficial debris. No biological growth to be reported inside the system. Humidity and moisture levels well within accepted tolerances.
Recommendations: Filter change 90 days, reinspect in one year.
