Aircon Servicing & Repair in Newcastle

Refrigerant does not get used up — if the level is low, there is a leak. A proper job is leak detection, repair, then regas, which costs several times a plain top-up but stops the problem recurring. Be wary of any technician who suggests routine annual top-ups.

Once a year is the minimum for a system used seasonally; every 3-4 months if you run it daily in a hot climate. Regular servicing keeps coils and filters clean, which protects the compressor — the most expensive part to replace — and keeps energy use down.

A common rule: if the repair costs more than half the price of a new unit, or the system is over 10-12 years old and needs a compressor or coil replacement, replace it. Newer inverter units are typically 30-50% more efficient, so heavy users recoup part of the cost through lower bills.

A chemical wash cleans the coil, blower, and drain pan in place. A chemical overhaul dismantles the indoor unit completely, soaks the parts, checks bearings and seals, and reassembles it. Choose an overhaul when a wash has not fixed persistent leaks, noise, or weak cooling, or for units neglected for years.

The most common cause is a clogged condensate drain line — dirt and algae block the pipe and water backs up into the room. Other causes are a dirty evaporator coil that ices over and then melts, a cracked drain pan, or an incorrectly sloped drain pipe. A drain flush during a standard service usually fixes it.

You can safely wash or replace filters monthly, keep the outdoor unit clear of leaves and debris, and wipe the indoor casing. Anything involving the refrigerant circuit, electrical components, or coil chemicals should be left to a certified technician — refrigerant handling is legally restricted in most countries.

A standard service on a midwall split runs R550-R950 per unit, and a regas (only after leak repair) R900-R1,800 depending on gas type. Metro rates (Joburg, Cape Town, Durban) are at the upper end; add a call-out fee of R300-R500 outside central areas.

Repeated hard power cuts and surges are a leading cause of failed compressors and PCBs. A surge protector or delay-start relay (R500-R1,500 installed) is cheap insurance; many technicians fit one during a routine service.
