In Sydney's sweltering summers, air conditioning repairs top the search list, from split system air conditioner repairs for weak cooling and noisy fans to ducted air conditioning repairs tackling frozen coils, refrigerant leaks, and leaking water.

Most jobs that come in are one of a handful of things. Not cooling or not heating. A unit throwing a fault code, or just not turning on. Water leaking where it shouldn't. Or a smell, either an electrical burning smell, which means switch it off and call us straight away, or a musty dirty-sock smell, which is almost always mould and gunk built up in the drain. A lot of the time the real cause is a tired PC board or a refrigerant leak. But we don't guess. We diagnose it properly first.

How our repair pricing works. Every fault's different, so we don't pretend to have a one-size price. You pay a call-out for us to come and find the problem, then we quote the fix before we touch it. No surprises. Labour's $125 an hour where it applies, and if it's a quick one we'll often just sort it on the spot.

How quickly we get there. We'll usually have someone out to look within the week. Once we know what's needed, the repair itself is generally done within a fortnight, though that can stretch if a part has to come in from the manufacturer. If it's an emergency, give us a bell and we'll do what we can.

Backed by warranty. All our repairs come with twelve months warranty on parts, the same cover we put on our installs. Labour isn't covered long term, which is standard across the trade, but the parts we fit are backed for a year. We repair every brand out there, Daikin, Panasonic, Mitsubishi, Fujitsu, Actron and the rest, ducted and split, homes and businesses. Got something playing up? Give us a call on (02) 9820 4500 and we'll get it sorted.

Common Problems

Air Conditioning System Problems We Fix

Panasonic Error Codes Explained

Panasonic flashing a code? To read it, press and hold the check or timer button on the remote until the display cycles to a code like H11, H15 or F11, or read it off the indoor unit. Panasonic uses an H prefix for most communication, compressor and electrical faults and an F prefix for sensors…

Mitsubishi Electric Error Codes Explained

Mitsubishi Electric throwing a code? First, make sure it is Mitsubishi ELECTRIC and not Mitsubishi Heavy Industries - they are separate companies with different codes, and the badge on your outdoor unit tells you which. For Mitsubishi Electric (the MSZ, MFZ and PEFY ranges), faults show as a letter-and-number code on the wall controller or…

Fujitsu Error Codes and Flashing Lights Explained

Fujitsu blinking at you? Here is how to read it. On older Fujitsu General splits, faults show as a pattern of the green operation light and the orange economy or timer light - count the flashes and the pauses, because the sequence is the code. On newer units you get a numeric code on the…

Daikin Error Codes Explained

Got a Daikin flashing a fault code? Here is how to read it. Point the remote at the unit and press the cancel or check button, or look at the indoor unit display - Daikin shows a two-character code like U4, E3 or A5. The first letter is the system area (U is communication, E…

How to Choose an Air Conditioning Company in Sydney

Who is the best air conditioning company in Sydney? The honest answer is that the best one for you ticks six boxes: a current NSW contractor licence, ARCtick refrigerant certification, its own employed technicians (not subcontractors), a fixed quote before any work starts, a genuine workmanship warranty, and a long track record of real reviews.…

Can You Regas an Air Conditioner Yourself?

Can you regas your own air conditioner? No. Handling refrigerant in Australia legally requires an ARCtick licence, and buying the gas without one is illegal too. More to the point: air conditioning is a sealed system. It does not consume gas like a car uses petrol. If yours is low, the gas leaked out -…

How Much Does Ducted Air Conditioning Cost in Sydney?

How much does ducted air conditioning cost in Sydney? For a typical 3-bedroom single storey, $7,000 to $10,000 installed for a 10kW system. A 4-bedroom home wants 12.5kW at $8,000 to $11,000. Big two-storeys and acreage run 14 to 16kW with zoning at $9,000 to $12,500. Those are installed prices including the duct runs and…

How Often Should You Service Your Air Conditioner?

How often should you service your air conditioner? Once a year minimum, ideally in spring before the season you flog it. Run it year-round for heating and cooling? Twice a year is the honest answer. The systems we service annually reach 15-plus years; the ones we meet for the first time when they die make…

What Is the Best Air Conditioner Brand in Australia?

What is the best air conditioner brand in Australia? After 30-plus years of installing and repairing them, our honest answer: a properly sized, properly installed mid-range unit beats a badly installed premium one every single time. That said, we install Panasonic, Daikin and Actron by choice - because they are the gear we are happy…

How Long Do Air Conditioners Last?

How long does an air conditioner last? A quality split system runs 12 to 15 years, a ducted system 15 plus, and the difference between the short end and the long end is almost entirely servicing. The compressor is usually the part that calls time - once it fails on an older unit, replacement beats…

Is It Cheaper to Leave Air Conditioning On All Day?

Is it cheaper to leave the aircon running all day? For most Sydney homes, no. Cooling an empty house for eight hours costs more than one hard pull-down when you get home, even though the pull-down uses peak power. The exception is a very well insulated home on a brutal day, where holding temperature is…

How Much Does Air Conditioning Cost to Run?

How much does air con cost to run in Sydney? A modern 2.5kW bedroom split costs roughly 40 to 60 cents an hour at full cooling. A 7.1kW living area unit runs about $1.20 to $1.80 an hour. A zoned ducted system cooling the whole house sits around $2 to $4 an hour at peak,…

Ducted or Split System Air Conditioning?

Which is better, ducted or split? If you want to cool one to three rooms, splits win - cheaper to buy, cheaper to run, no roof work. A 2.5kW split installed is $1,800 to $2,100. If you want the whole house comfortable, ducted wins - one system, every room, nothing on the walls. A 12.5kW…

Ice on Air Conditioner?

Ice on the unit means the system cannot shed heat properly. Start by turning it off and cleaning the filter. A blocked filter is the most common cause. If ice comes back after that, call us for a proper check.

Air Conditioner Error Codes

Error codes mean the system has detected a fault and wants you to know about it. Codes vary by brand, so write down what you see and give us a call. Most codes point us straight to the problem and save time on diagnosis.

Air Conditioner Making Noise?

Rattling usually means something has come loose inside the unit. Squealing or grinding points to a motor or fan bearing on the way out. Clicking at startup is often a relay or capacitor. Do not wait on noise faults. They get worse fast.

Air Conditioner Smells Bad

A musty smell means mould has built up on the coil or in the drain pan. Very common in humid Sydney conditions. A burning smell is an electrical fault and needs attention straight away. Call us if you are unsure which it is.

Air Conditioner High Power Bills?

A dirty filter or blocked coil makes the system work twice as hard for the same output. If your power bills have jumped noticeably, a service is usually the fix. Refrigerant issues and ageing compressors can also push running costs up.

Air Conditioning Not Cooling

If the system is running but not actually cooling, the usual suspects are refrigerant, a dirty coil, or a failing compressor. Check the filter first. If that is clean and it is still not cooling, it needs a proper diagnosis.

Air Conditioning Leaking Water

Water leaking from the indoor unit is almost always a blocked drain line. It can also mean the coil is freezing and thawing. Either way, get it sorted quickly. Water inside the unit can damage the electrics.

Air Conditioner Not Turning On

If the unit will not start at all, check the circuit breaker and remote battery first. Beyond that, it is usually a failed capacitor, control board, or thermostat. Quick to diagnose once we are on site.

Air Conditioning Not Heating

Heat pump systems can struggle in very cold weather, but if yours stops heating in normal conditions it is usually a refrigerant issue or a reversing valve problem. Both are diagnosable and fixable same-visit.
