1. Overview

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.
