Our cleaning procedure begins with shutting off power. This prevents cross contamination and keeps our technicians safe. Next the cleaning begins. Supply registers and return grills are removed and cleaned with an antimicrobial solution. While the registers and grills are cleaned, a portable rotary brush HEPA vacuum is used to disturb and extract contaminants from the ductwork. Access is made through register and grill openings and vacuuming occurs until the ductwork is visually clean. For a coil cleaning, a dry cleaning and a wet cleaning is performed. The dry cleaning involves contact vacuuming with a HEPA filtered dry vacuum. The wet cleaning involves a commercial grade acid and alkaline free coil cleaner. Upon completion, results are documented and photographed.
