Questions & Answers

Frequently Asked Questions

What is a PCB in an aircon?

PCB stands for Printed Circuit Board. It is the electronic brain of your aircon that controls all functions including cooling, fan speed, temperature sensing, and error detection. A faulty PCB can cause the unit to malfunction or stop working completely.

How do I know if my PCB is faulty?

Common signs include aircon not responding to remote control, blinking error lights, frequent on-off cycling, inconsistent cooling, or the unit not turning on at all. A technician can diagnose PCB issues using professional tools.

Can Diamond City Aircon Service replace all types of parts?

Yes, we replace all types of aircon parts including PCB boards, fan motors, capacitors, thermistors, sensors, expansion valves, compressors, and more for all major brands and system types.

How long does a parts replacement take?

Most parts replacements take 1-3 hours depending on the component and system complexity. PCB replacement typically takes 1-2 hours, while compressor or fan motor replacement may take longer.

Are the replaced parts genuine?

We use original manufacturer parts or high-quality compatible parts that meet or exceed manufacturer specifications. We clearly communicate which parts are being used before starting any replacement work.

Is it safe to operate an AC with faulty parts?

No, operating an aircon with faulty components can cause further damage to the system, increase electricity bills, and in some cases pose electrical safety risks. It's best to turn off the unit and schedule a repair.
