Air Conditioning Installation in Durban & the North Coast

Why correct sizing matters more than brand

An oversized unit is the single most common installation fault we are called out to fix. It cools the air fast, satisfies the thermostat, and switches off before it has removed any moisture — so the room ends up cold and clammy, the compressor short-cycles, and the unit wears out years early. An undersized unit runs flat out and never reaches setpoint. In Durban’s humidity, getting the sizing right is what separates a system that lasts fifteen years from one that becomes a recurring problem.

Coastal installations need coastal-grade hardware

If you are within a few kilometres of the sea — Umhlanga, Umdloti, Salt Rock, Ballito, Zimbali — salt-laden air attacks the aluminium fins and copper of the outdoor condenser. Untreated coils can corrode visibly within two or three seasons. We specify blue-fin or anti-corrosion coated condensers for coastal sites, mount units clear of direct spray and prevailing salt wind where the building allows, and use stainless or hot-dip galvanised brackets rather than the standard painted mild steel.

What a proper installation includes

Pipework is flared and torqued to spec, insulated over its full length, and pressure-tested with dry nitrogen before any refrigerant enters the system. The system is evacuated with a vacuum pump to remove moisture and non-condensables — skipping this is why some units fail inside two years. Condensate is drained to a legitimate outlet with correct fall, not left to drip down a wall. Electrical supply is checked and, where needed, a dedicated circuit and isolator are installed by our qualified electrician.
