How We Diagnose and Repair AC Faults

Modern air conditioning systems have onboard diagnostic systems that store fault codes when something goes wrong. The error code displayed on the indoor unit or controller tells our engineers exactly which component or circuit has triggered the fault — before they even open the unit. We carry manufacturer service data for most major brands and can cross-reference any error code on site.

Once we have identified the fault, we explain whether it can be repaired during the visit or whether a part or further work is required. Common issues include low refrigerant charge, failed thermistors, blocked condensate drains, faulty capacitors and PCB faults. We provide a written repair report detailing the fault found, the recommended repair and any parts used.

  • Error code diagnosis using manufacturer service data — most major brands
  • Refrigerant pressure and temperature checks to identify charge loss
  • Component testing — thermistors, capacitors, fan motors, PCBs
  • Condensate drain investigation for water leak faults
  • Electrical supply and wiring checks for nuisance trip faults

Honest Repair vs Replace Advice

We tell you honestly when a repair is worthwhile and when it is not. An older system with a failed compressor may cost more to repair than its remaining working life justifies — and in that case we will say so and quote for a replacement instead. We do not charge for diagnosis if we recommend replacement and you proceed with us.

Common AC Faults We Repair

We diagnose and repair the full range of air conditioning faults — from simple filter blockages to compressor and PCB replacement.

❄️

Not Cooling

Common causes include low refrigerant charge, dirty indoor coils or a faulty thermistor. We identify the root cause and explain the repair options.

💧

Water Leaking

Leaking indoor units are almost always caused by a blocked condensate drain. We clear the blockage and treat the drain to prevent recurrence — a 30-minute fix.

🔊

Noisy Operation

Rattling, buzzing or grinding from the indoor or outdoor unit points to fan blade damage, loose components or a failing fan motor — all repairable.

⚡

Tripping the Electrics

Nuisance tripping is usually caused by an insulation fault on a component or wiring, or a failing capacitor. We carry out full electrical testing to identify the cause.

🌡️

Poor Temperature Control

Systems that fail to reach the set temperature are often suffering from low refrigerant charge, dirty coils or a faulty indoor thermistor — all diagnosable and repairable.

📟

Error Codes

We decode and resolve error codes for most major brands — Daikin, Mitsubishi, Samsung, Toshiba, Fujitsu, LG and more. Tell us the code and we can advise before we visit.

We Repair All System Types

From a single wall-mounted domestic unit to a multi-site commercial VRF installation — we diagnose and repair them all.

Wall Mounted Units

The most common domestic system — fault finding completed before repair options are agreed.

Ceiling Cassettes

Cassette unit repairs including motor, PCB and condensate pump replacement — full access to all components.

Ducted Systems

Concealed ducted system repairs with access via unit panels and service hatches — all faults resolved on site.

Multi-Split Systems

Multi-split fault finding across all indoor units and the outdoor unit — identifying which branch of the system has the fault.

VRF / VRV Systems

Large commercial VRF systems repaired under planned maintenance contracts or on a call-out basis.

Refrigerant Service

If low refrigerant charge is the cause of poor cooling, we locate any leak, repair it and recharge the system.

Post-Repair Service

After a repair, a service visit ensures the system is clean, correctly charged and operating at peak efficiency.

All Servicing

Our Repair Process

Fast, transparent diagnosis with a clear repair or replace recommendation — no unnecessary return visits.

1

Diagnosis

We read fault codes, check operating pressures and temperatures, and test individual components to identify the root cause of the fault.

2

Quote

We give you a clear, fixed repair quote before any work starts — parts and labour included. Any extra work is discussed before costs are incurred.

3

Repair

We complete the repair during the visit where possible. If parts or further work are required, we explain the next steps before proceeding.

4

Test & Report

System run and tested after the repair. Written repair report provided detailing the fault, repair and parts used.

Frequently Asked Questions

My AC is showing an error code — what does it mean?

Error codes vary by manufacturer and model but generally indicate a specific component or circuit fault. Common codes relate to thermistor failure, refrigerant pressure out of range, fan motor fault, or communication errors between the indoor and outdoor units. Tell us the make, model and error code when you book and we can advise on the likely cause and expected repair cost before we visit.

Can you repair a system you did not install?

Yes. We repair most major brands regardless of who installed them, subject to manufacturer, model, age, condition and parts availability. If you have a system under warranty with the original installer and they are no longer available, we are happy to carry out the repair and provide a report — though warranty claims in this situation would need to be addressed directly with the manufacturer.

Water is dripping from my indoor unit — is this serious?

It is common and almost always caused by a blocked condensate drain — a straightforward fix. Left untreated, the water will eventually overflow and damage ceilings and walls below the unit, so it is worth getting it addressed promptly. We can usually attend and clear the blockage within the week.

When is it better to replace rather than repair?

As a general guide, if the cost of a repair exceeds 50% of the cost of a new system and the existing system is more than 10 years old, replacement is usually the better investment. We give you an honest assessment on every job — if replacement is the better option, we will tell you and provide a replacement quote at no extra charge.
