The installation, commissioning, maintenance and repairs of air-conditioning, refrigeration, cold rooms, cooling towers, heating and ventilation systems.
When you are planning to install a new HVAC system in your home or office, it is important to select the air-conditioner of proper tonnage and specifications. Too small an air-conditioner won’t give you the desired cooling effect, hence your investment on the machine will be wasted. Too big an air-conditioner will not only increase your initial cost of the machine but also its running cost.
Air conditioning systems are accountable for the bulk of energy consumption in a building. Typically, the ‘functional life’ of a HVAC system is 8-10 years. So, if your HVAC system is more than 10 years old, it’s time to consider replacement. When weighing up the capital cost of replacement, consider that new units can reduce energy costs by 20 – 40 per cent.
HVAC components which typically require upgrading include:
– Drives and motors on pumps, fans, electronic valves, chillers, etc.
– Air handling units, cooling coils
