The HVAC system and network of air ducts were visually inspected and cleaned. The information in this report is private and shared only with property owners Jose and Sibyl Velez. 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 a two-floor residence. The property had one air handler (see specifications below). There were a total 12 registers, ten supply and two returns. 225 feet of duct was cleaned as was 50 feet of return duct including the main trunk. Multiple access points were used to allow for manual cleaning and to attach a negative air machine. Upon departure all door handles, light switches and other touchable surfaces were sanitized.
Additional On-site Repairs/Areas of concern:
Overall structure of the system was in mechanically good condition. A thorough cleaning improved efficiency and air quality. However, it is recommended that the duct system be inspected in two years due to the extensive debris (pet hair) found in the system.
2. Project & System Specifications
Cleaning Method and Air Handler componets specified on page 6 of procedural report below.
3. Air Handler(s)
One forced hot air furnace was inspected, cataloged and cleaned. The systems was in good working order. No biological growth to be reported inside the systems. The unit had humidity and moisture levels well within accepted tolerances. See photo slide-deck.

Fans, Vents & Registers: Twelve (12) 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: Supply trunk was found to be sealed and was cleared of a significant amount of debris, mostly pet hair. It was free of both moisture and biological contaminants. Access point were cut and re-sealed by SMACNA international standards. See photo deck.
Ductwork: 8"duct connections were found intact. The home space was left sealed and intact. Ductwork contained a significant amount of debris and was cleared. Access points were used in the ductwork 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).
6. Containment, Equipment & Condensers
Containment Special attention was paid to containment. Furniture throughout the space was covered with .3 mil plastic to prevent cross-contamination.
Equipment: Nikro 5000 CFM Negative Air Machine. 2-Stage HEPA Filtration with 99.97% filtration. 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.
Condenser unit was cleaned and was in good working order. Coil cleaner was used to improve efficiency of the coil assembly.
