The HVAC system and network of air ducts were visually inspected and cleaned. The information in this report is private and shared only with the owners of this property. Interpretation of the data collected in this assessment is meant to inform as to the condition of their HVAC system and other potential issues related to this property.
The work area consisted of entire living space of the first and second floors, basement and attic. The residence had two air handlers, one in the basement and one in the attic (see specifications below). There were a total 16 of registers, including returns. 275 feet of flex duct was cleaned as was 75 feet of return duct including the main trunks. Three bath fans and one dryer vent and associated ducting were also inspected and cleaned. Multiple access points were cut in the galvanized main trunks to allow for manual cleaning and to attach a negative air machine. Access points were summarily sealed according to SMACNA standards described in the procedural standard in section seven below. All door handles, railings, light switches and other touchable surfaces were sanitized upon departure. Please refer to photo slide-decks below for additional observations and notes.

Two forced hot air furnaces were inspected, cataloged and cleaned. The systems were in good working order. No biological growth to be reported inside the systems. Both units had humidity and moisture levels well within accepted tolerances. See photo slide-decks.
The dryer vent was inspected and cleaned with a four-inch nylon brush and a forward blowing compressed air nozzle. Minimal amount of debris was extracted and the area behind the appliance was also cleaned.
5. Ductwork, Registers & Vents
Fans, Vents & Registers: Sixteen (16) vents and registers were removed in order to accessed ductwork for manual cleaning. Registers were summarily cleaned and replaced in a pre-recorded order.
Bathroom Exhaust Fans: Three exhaust fans were cleaned and left in good working condition. Bathroom units showed no sign of excessive moisture or biological contaminants.
Main Trunk: AHU 1 (basement) supply trunk was found to be sealed and was opened and cleared of moderate dust and some heavy debris. AHU 2 (attic) also had moderate dust. Both were free of moisture or biological contaminants. Access points were sealed according to SMACNA standards.
Ductwork: The flexible ductwork was found intact throughout the home containing a moderate level of dust. Multiple access points were used in both the supply and return trunks 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 8" nylon brush (whip). Once agitated, the debris was blown from the system using a forward facing nozzle with compressed air.
6. Containment, Equipment & Condensers
Containment Special attention was paid to full containment. Furniture, carpets, and other items throughout the space were covered with .3 mil plastic to prevent cross-contamination. Floor covering was used in the main kitchen area (hardwood floors) as an added layer of protection.
Equipment: Nikro 5000 CFM Negative Air Machine. 2-Stage HEPA Filtration with 99.97% fliltration. 5" static pressure, 115v/13 each of two motors. Varying sizes of Nylon and Silica rotating brushes (whips). 115v electric oil-free air compressor with forward & reverse blowing nozzles.
Two outside condenser units were congested with leaves. Both were dismantled and cleaned with compressed air and aluminum fins were combed and coil cleaner used to improve efficiency.
