Air conditioning in Richards Bay
Twin Core is a local company based in Mandlazini. We install, service and repair air conditioning and refrigeration with the city's heat, humidity and sea air in mind.
Why the coast is hard on cooling equipment
Richards Bay summers are long, hot and humid. An air conditioner here is not only cooling the air, it is removing a lot of moisture from it, and that is where correct sizing matters. Too big a unit leaves rooms cold and clammy; too small and it runs flat out all afternoon.
Salt in the air settles on outdoor coils, fins and electrical connections. Combined with humidity, it speeds up corrosion, especially for units close to the beach, the harbour or industrial areas. Dust and debris clog coils and push running costs up.
None of this means a system cannot last. It means placing outdoor units sensibly, draining condensate properly and servicing more often than you would inland. Those are the habits we bring to every job.

How often should air conditioners be serviced in Richards Bay?
Homes should service at least once a year, ideally before summer. Businesses, busy shops and units close to the sea or harbour do better with a service every three to six months, because salt and dust build up faster.
