Daikin Not Cooling or Showing an Error?
We'll Fix It Properly.
Got a Daikin that's not cooling, leaking or flashing an error code? Here's the deal. We repair every Daikin sold in Australia, ducted and split, and we've been doing it since 1991. A service call to diagnose the fault is $250 plus GST, we quote the fix before we start, and most common Daikin faults are sorted the same visit.
The faults we see most on Daikin gear are PC boards, fan motors, sensors and the odd refrigerant leak at the flares. That's daikin air conditioning repairs sydney owners can actually rely on, with genuine parts where they're needed.
Daikin is good gear, which is exactly why it's usually worth repairing. A failed board or sensor doesn't mean a new system. We carry the common parts, fit genuine replacements where it matters, and every repair part carries lifetime workmanship warranty.
Family run, our own techs, fixed pricing and no upsell. 4.8 stars from 280+ reviews. Give us a bell on (02) 9820 4500 for Daikin repairs Sydney wide. And if the old unit really is done, see our pricing guide for what a new one costs.

What We See in
Sydney Daikin Systems
Extreme Heat
Sydney summers push Daikin condensers hard. Capacitors and fan motors cop the worst of it on 40 degree runs.
Poor Airflow
Packed filters and dirty coils choke the indoor unit. Half the weak-cooling Daikins we see just need a proper clean.
Coastal Corrosion
Salt air eats outdoor coils and cabinets near the water. Corroded coils end up leaking gas.
Heavy Usage
Daikins that run all day, every day wear parts early. Boards and sensors usually go first.

How We Diagnose Daikin Faults
We don't rely on guesswork, and we don't swap parts until something works. We test the system properly and look at the fault as a whole - operating pressures, temperatures, electrical readings and airflow - then fix the actual cause. Here's how a Daikin diagnosis runs:
00
Airflow
Filters, coils and fans first. Choked airflow mimics low gas and trips protection codes.
00
Electrical
Boards, capacitors and sensors tested properly, not guessed at. Daikin codes point us to the right circuit.
00
Refrigerant
Gauges on, pressures read. If it's low it's leaked, so we find the leak before any regas.

Why We Don't Cut Corners
There's a reason Daikin owners call us back. We don't regas a leaking system and drive off. We don't swap parts on a hunch and bill you for the experiment. And we don't talk you into a new system when a $300 repair will do.
Every Daikin repair starts with a proper diagnosis. Pressures, electricals, airflow, the lot. You get the actual fault and a fixed quote before we touch a spanner. If the maths says repair, we repair it with genuine parts and 12 month warranty on those parts, plus our lifetime workmanship guarantee. If the maths says replace, we'll show you why and quote both ways.
That's how a family business holds a 4.8 star rating across 280+ reviews after 35 years. No shortcuts, no surprises, no subbies.
Repair or Replace Your Daikin?
Daikins are worth repairing more often than most brands. Under 10 years old with a board, sensor, fan or gas fault? Repair it. Past 12 to 15 years, on old R22 gas, with a dead compressor? That's when replacement wins, and newer inverter Daikins cost a fair bit less to run.
Use our sizing calculator to see what you'd actually need, and our pricing guide for install costs. Either way you get the honest call, not the dearest one. A struggling Daikin also chews power, so if the bills have jumped, see our high power bills page.
What Happens on a Repair Visit
We start with proper diagnosis so we can identify the fault before recommending any repair. That includes checking operation, airflow, drainage, electrical readings, and the way the Daikin system behaves under load.
Once the issue is confirmed, we explain the problem clearly, tell you what needs to change, and give you clear pricing before work begins. If the repair can be completed on the spot, we do it. If parts are required, we organise the next step quickly and keep it straightforward.

System Diagnosis
Gauges, electrical tests and airflow checks on the whole system, not just the bit that's complaining.
00
Plain English Explanation
We tell you what we found in plain English, not jargon.
00
Root Cause Found
We chase the cause, not the symptom, so the same fault doesn't come back next month.

Upfront Quote
Fixed quote before any work starts. You say go, or you don't.

Fixed, tested under load and cleaned up. 12 month warranty on parts, plus our lifetime workmanship guarantee.

Usually low gas from a leak, packed filters or a failed capacitor. Wash the filters and restart it at the isolator first. If it’s still warm, it needs gauges on it. See our aircon not cooling page for the full rundown.
$250 plus GST to diagnose, then a fixed quote before we fix anything. Capacitors run $150 to $180, sensors $250 to $350, boards $400 to $700. Most common fixes are done the same visit.
Daikin codes come in families. A codes are indoor, E codes outdoor, U codes communications, C and J codes are sensors. Write the code down, restart at the isolator, and if it comes back, call us with the code. It saves diagnosis time.
Yes, both. Splits, multi-heads, ducted and cassettes, every Daikin model sold in Australia. Genuine parts where they matter, 12 month warranty on parts, plus our lifetime workmanship guarantee.
Under 10 years old, repair it nearly every time. Past 12 to 15 years on old R22 gas with a dead compressor or board, replacement usually wins. We quote both ways and give you the honest call.
