How a repair works

No call-out lottery. You know the price before an engineer touches your system.

1

Describe the fault

Not cooling, leaking, noisy, or showing an error code — tell us the symptoms and your postcode.

2

Engineer diagnosis

A vetted contractor inspects the unit, checks refrigerant, electrics and drainage, and identifies the fault.

3

Fixed-price quote

You'll get a clear repair price before any work goes ahead — no hourly rate, no surprise add-ons.

4

Repair & test

Your contractor fixes the fault, test the system under load, and leave you with a working unit and a written summary.

Repairs done properly, not patched over

Real diagnosis, not guesswork

Contractors identify the actual fault — refrigerant leak, failed PCB, blocked drain — rather than swapping parts until something works.

Domestic and commercial cover

From a single bedroom split system to multi-unit office and retail installations, including F-Gas regulated refrigerant work.

Any brand, any age

Daikin, Mitsubishi Electric, Panasonic and most other major brands — even if we didn't arrange the original install.

Honest advice on repair vs replace

If a unit is old or the repair cost approaches a new install, we'll tell you plainly rather than patch it repeatedly.

Common faults our contractors fix

Units that won't cool, run constantly, trip the breaker, or display a fault code are usually refrigerant, electrical or sensor issues — all diagnosable on a single visit.

Leaks and drainage issues

Water dripping from an indoor unit is almost always a blocked or disconnected condensate drain — straightforward to fix and a common cause of ceiling and wall damage if left.

Frequently asked questions

How much does air conditioning repair cost?

Cost depends on the fault — a blocked drain or sensor issue is far cheaper than a refrigerant leak or failed compressor. Contractors diagnose first and give you a fixed price before any work starts, so there's no surprise on the invoice.

Why has my air conditioner stopped cooling?

Common causes include low refrigerant from a leak, a dirty filter restricting airflow, a faulty compressor, or an outdoor unit that's blocked or iced up. An engineer can usually identify the cause on a single visit.

Why is my air conditioning unit leaking water?

This is almost always a blocked, disconnected, or poorly sloped condensate drain line. It's a common and usually inexpensive repair, but should be fixed quickly to avoid water damage to walls or ceilings.

Do you offer emergency or same-day repairs?

We prioritise urgent enquiries and match you with contractors for units that have failed completely, especially for commercial sites like server rooms, restaurants, and offices. Tell us the urgency when you request a quote and we'll match you with the fastest available contractor.

Can you repair a unit installed by someone else?

Yes. Our vetted contractors work on most major brands and system types, whether we arranged the original install or not.

Is it worth repairing an old unit or should I replace it?

If the unit is over 10 years old, uses an older refrigerant, or the repair cost is a large fraction of a new install, we'll tell you honestly so you can decide — contractors won't push repeat repairs on units past their economic life.
