HVAC&R SYSTEMS - THE CONSEQUENCES OF CYCLONES

What risks do cyclones pose to HVAC&R equipment?

Weather events such as flooding and cyclones pose significant risks to HVAC&R equipment in homes and businesses

The Climate Controls Companies Association New Zealand (CCCANZ) advises homes and businesses to take important safety measures regarding heating and cooling systems when cyclones and severe flooding impact New Zealand. Buildings exposed to flooding and water damage can affect heaters, furnaces, boilers, air-conditioning, ventilation, heat pumps and refrigeration systems, putting people at risk.

Many people may not understand the need to replace flood-damaged air conditioning, heating and refrigeration equipment – they believe that their system has dried out and is once again fully operational, however, damage is not always going to be apparent. CCCANZ advises people to play it safe and replace, rather than repair flood-damaged heating, cooling and water heating equipment.

HVAC&R equipment affected by standing water will typically be damaged beyond cost-effective repair, with fully submerged equipment requiring the replacement of all exposed electrical components and motors. There are also potential health issues like mould and disease caused by contaminated floodwaters.

If there is any question that flood water has reached heating and cooling systems, including domestic appliances such as heat pumps and refrigerators or freezers, equipment should be checked by a qualified professional. If you are concerned about receiving the right advice, look for a company that is a member of the CCCANZ and whose people are accredited through the Institute of Refrigeration, Heating and Air Conditioning Engineers (IRHACE). This is particularly important for commercial and industrial businesses where mould issues may not be apparent and thorough cleaning and inspection are required.
