At this meeting, any problems being experienced by the client would be identified and clarified where possible. Some of these problems may include smells from particular areas, discharge from vents, general dust over the office environment, poor airflow etc. some of these issues may be localized or problems overall with the air-conditioning system. Arrangements would be put in place to inspect the system in order to identify these issues.
The inspection serves to identify exactly where and to what extent problems exist. Several areas of the system will need to be inspected including the Air Handling Units, coils, filters, supply air vents and several access points in the ductwork. The condition of any internal fiberglass lining that has deteriorated or is shedding into the air stream would included in the inspection.
For buildings which impose very strict demands on the indoor air quality, samples of the dust can be taken. These samples can be examined for their composition and the content of bacteria and fungi. After inspection and analysis it is possible to work out a proposal for the work/cleaning to be carried out.
The proposal would include photographic evidence of problems identified, bacterial and mould analysis when part of the requirements, and a suggested maintenance program. The extent and time used for a cleaning can be difficult to estimate as most ductwork is not installed to allow for future maintenance, any access issues would be included in the proposal.
