Air Handling Units
Ventilation and air-conditioning systems which are poorly installed or maintained may be a health risk to the public.
The Council can provide advice and guidance on all aspects of installation and can require that detailed plans are submitted for inspection prior to installation of new units. This particularly applies to catering establishments.
Air handling units within buildings may be linked to air conditioning systems.
Some air conditioning systems e.g. those which use evaporative cooling, may pose potential health risks if not properly maintained.
The message is therefore "make sure your air handling units are serviced at appropriate intervals, and follow the instructions by the supplier or manufacturer".
