HVAC servicing includes Mechanical ventilation which plays an essential role in the standard commercial building. The most common use for mechanical ventilation is Fire stair pressurisation, Car park exhaust systems, Toilet exhaust systems and fresh air induction systems.
The motors and associated controls require regular routine inspection to ensure optimum performance and energy consumption. As this equipment can form part of the evacuation and fire safety system, it is essential to have the equipment performing at its best. Quarterly and annual tests are carried out for compliance purposes to ensure all standards and regulations are met.
Over time these fans will move hundreds of thousands of litres of air through the ducts which leads to dust and dirt build up. Duct clean may be required in some instances to remove heavy deposits.
Fan motors and impellers should be checked regularly to ensure no undue wear exists to the bearings and seals as these are common stress points. HVAC serving ensures regular attention to prevent major mechanical failure.
