Which faults do you see most often in Johannesburg?
On heat pumps in this area the recurring issues are heat pump making noise, heat pump compressor fault, heat pump high pressure fault. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
