Flash Restore’s Air Duct & HVAC Cleaning process:

Before commencing work, assess HVAC system condition to determine appropriate engineering controls, safety measures, tools, equipment and cleaning products and methods required to complete the work.

Sample Cleaning Steps:

a. Clean HVAC system from point where air enters system to each point where air is discharged
from system.
b. Clean HVAC system as indicated on Drawings.
c. Clean existing supply, return and exhaust air ducts.
d. Clean reheat coils and supply air ducts downstream of reheat coils.
e. Clean air handlers and associated existing return air ducts.
f. Clean exhaust systems
g. Seal internally-lined supply ducts with approved coating in accordance with manufacturer’s instructions. Seal edges and
seams of internal duct liner in accordance with liner and sealant manufacturers’ instructions.
j. Clean fan coil units. Clean cabinets, coils, and blowers located within fan coil unit.

Determining the Need for HVAC Cleaning & Restoration

It is recommended that HVAC systems be cleaned when a proper HVAC cleanliness inspection or building history indicates one or more of the following conditions exist:

• The HVAC system is contaminated with an accumulation of particulate;
• The HVAC system performance is compromised due to contamination build-up;
• The HVAC system has been determined to be a source of unacceptable odors;
• The HVAC system is discharging visible dirt or debris into the conditioned space;
• The HVAC system has been contaminated as a result of fire, smoke, and/or water damage;
• The HVAC system has been infested with birds, rodents, insects, or their byproducts;
• The HVAC system has been determined to be at risk for fire hazard;
• The HVAC system has become contaminated with construction debris or dust;
• Mold contamination conditions have reached either Condition 2 or Condition 3;
• Deterioration of fiber glass duct liner, duct board, or other porous components;
• As part of an HVAC maintenance program as defined in ANSI/ASHRAE/ACCA Standard 180;
• As part of the HVAC equipment manufacturers recommended maintenance practices;
• As part of a proactive energy management program;
• As part of a proactive indoor air quality management program;
• As a component to achieve LEED Certification;
• When a newly installed component or duct has been contaminated with construction and/or other dust and debris.
