HVAC System Cleaning Procedure
The proposal process
We come out to your building free of charge and discuss with you your needs. We do an overview inspection
of your systems, evaluate your needs and then recommend a solution. We then create a proposal for you
usually with options for you to consider.
Proposal acceptance phase
If you accept our proposal we then discuss with you a plan of action and schedule a time frame for the work to
begin based upon your convenience.
Assessment phase
We then do a detailed assessment of the project. We consider the type and use of the building to plan for
containments and protective measures we need to take to insure the safety of the building occupants and the
building structure and furnishings.
Scope of work and work plan
Based upon our assessment we then chalk out a scope of work and a work plan so that our technicians know
which components to clean, what techniques to employ to clean them, what protective measures they need to
take to protect the building and its occupants, and all the information our technicians need in order to
successfully complete the project.
Scheduling phase
After we have a scope of work we then allocate the proper manpower and equipment that will be necessary to
complete the project on schedule.
Arrive at sight
Safety is our first priority. When we first arrive at the sight we review any site specific safety requirements
before we begin work.
Protecting building and furnishings
We usually start the project by covering desks and furnishings and carpeting with plastic drop cloths and put
corner protectors on the walls as and where required.
Inspection before cleaning
A visual inspection of air duct is an important part of our service. Our RoboCam helps to reach out
places where human eye cannot reach. A thorough inspection is done using RoboCam and Inspection
Video System (IVS). The RoboCam is inserted into the duct through any of the grills or any opening.
Information received on the IVS is carefully viewed and also recorded on a SD Card for evidence of
work. Still pictures are also taken using digital cameras to photo document the condition of the duct.
Cleaning phase
Clean one system at a time. When we are cleaning a HVAC system we try to clean one system in its entirety
before moving on to the next system. We clean the following components on a full system clean
The air handler including the heat exchangers, the blowers, the filter racks, the plenums, the drain
pans and the entire air passage way
We wash the evaporator coils
We clean the full length of the supply air ducts
