Switch the unit off to protect the compressor and call KFRCOOL on 078 298 4438 — our Randburg technicians diagnose and fix most faults on the first visit.

If your unit is over 10 years old, uses R22 refrigerant, or needs a compressor replacement costing more than about half the price of a new unit, replacement with an R32 inverter system is usually better value — it can cut running costs by up to 60%. Our technician gives you both options in writing.
