Fault Diagnosis

Common AC Faults We Fix

AC problems range from minor nuisances to full system failures. Our engineers have seen and fixed them all. Here are the most common issues we diagnose and repair — and what usually causes them.

🌡️

Not Cooling (or Heating)

The most common complaint. Usually caused by low refrigerant from a leak, a dirty condenser coil, a failed compressor or a blocked filter restricting airflow. We diagnose accurately before quoting any repair.

⚠ Common Fault
💧

Water Leaking Inside

Water dripping from the indoor unit almost always means a blocked condensate drain line. Left untreated, this can cause water damage to ceilings and walls. A straightforward repair when caught early.

Unusual Noises

Rattling suggests loose components. Grinding or squealing points to worn fan bearings. Clicking on start-up can indicate a failing capacitor. Each sound has a cause — we trace and fix it at the root.

⚠ Investigate Quickly

Musty or Bad Odour

A musty smell when the unit runs is a classic sign of mould or bacterial growth — usually in the drainage system or on evaporator coils. This is a hygiene concern as well as a performance issue.

⚠ Hygiene Issue

Tripping the Electrics

An AC unit that trips the circuit breaker has an electrical fault — potentially a failing capacitor, compressor drawing too much current, or a wiring issue. Never ignore a unit that repeatedly trips the board.

Error Codes & Control Issues

Modern AC units display error codes when a fault is detected. We carry manufacturer diagnostic tools for all major brands, allowing us to read fault histories and identify the precise cause efficiently.

⚠ Diagnostics Needed
🔥

Poor Performance / High Bills

A system that runs constantly but never reaches temperature, or that's driving up your electricity bill, is likely running on low refrigerant, has dirty coils or has a failing component reducing its efficiency.

Ice Build-Up on Unit

Ice forming on the indoor or outdoor unit indicates restricted airflow (often a blocked filter) or low refrigerant. Running a frozen unit risks compressor damage — switch it off and call us promptly.

Remote / Wi-Fi Control Failure

Control board faults, failed infrared receivers and Wi-Fi module failures are increasingly common as connected systems age. We carry replacement control boards for all major brands.

How We Work

Our Repair Process

We believe in diagnosing correctly before quoting. You'll never be hit with a surprise bill — every step is discussed with you before we proceed.

01

Accurate Fault Diagnosis

We arrive with the right diagnostic equipment for all major brands. We don't guess — we test. Error codes are read, pressures checked and electrical components tested before we tell you what's wrong. This means our first-visit repair rate is high, saving you time and money.

02

Transparent Quote Before Any Work

Once we've diagnosed the fault, we give you a clear, upfront repair cost before we do anything. If the repair isn't cost-effective relative to the age of the system, we'll tell you honestly — including our recommendation on whether replacement makes more sense.

03

Quality Parts & Certified Repair

We use genuine OEM parts wherever possible, or approved equivalents from reputable suppliers. All refrigerant work is carried out in accordance with F-Gas regulations by our certified engineers, with records maintained correctly.

04

Post-Repair Test & Sign-Off

After repair, we run the system through a full test cycle — checking temperatures, pressures and performance before we leave. We don't consider the job done until the system is working correctly and you're satisfied.

All makes and models covered. We repair systems from every major manufacturer. If we can't source the part or the repair isn't viable, we'll say so — and can provide a competitive installation quote to replace the unit if needed.

Diagnose First, Quote Second

We never quote a repair until we've accurately diagnosed the fault. This means you always know exactly what's wrong and exactly what it will cost to fix before we start.

Fast Response

We treat a broken AC as the urgent problem it is — especially in summer. We aim to respond quickly and get your system back up and running with minimal delay.

F-Gas Certified

Any repair involving refrigerant gases requires F-Gas certification. Our engineers are fully qualified — ensuring the work is legal, safe and correctly documented.

Honest Advice

If your unit is old and the repair cost isn't worthwhile, we'll tell you. We'd rather give you honest advice than take your money for a repair that won't last.
