John Thompson Gas Boiler Repairs in Craighall North
John Thompson gas boiler repairs in Craighall North. Locally manufactured industrial plant with strong local parts support.
John Thompson equipment we work on includes packaged steam and hot water boilers. Commonly replaced parts on this brand are level controls, burners, refractory, and we keep or source these against the unit's model and serial plate rather than by guesswork.
Gas boiler repairs concentrate on the ignition and flame supervision chain: gas train, solenoids, ignition transformer, electrode gap, flame rod or UV cell, and the air proving switch. Lockouts are a symptom; the fault is normally in gas pressure, air proving or a dirty sensing path.
Craighall North is a high-value residential pocket of Rosebank, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Craighall North falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
