Air conditioner repairs in Traralgon

Most air conditioner repairs in Traralgon start with one of five complaints: the unit will not heat on a cold morning, it blows cold air in heat mode, water drips from the indoor head, ice forms on the pipes or coil, or the display flashes an error code. A refrigerant technician finds the cause, then tells you whether it is a minor fix, a major repair or a regas, or whether the unit is worth replacing. You can describe the fault through this site and an independent local business with the right licences will contact you, look at the system and quote its own price.

What faults do people in the Latrobe Valley call about?

Reverse cycle units here work hard at both ends of the year. The weather station at Latrobe Valley Airport, using Bureau of Meteorology long-term figures, records winter lows that average 3.7 C in July and summer highs that average 26.8 C in January. Its extremes run from minus 4.8 C up to 46.3 C. A unit that copes in autumn can show its weak points on the first frosty morning or the first 40 degree afternoon.

The common symptoms, and what they can point to:

What you notice	Possible causes a technician will look at
No warm air on a cold morning, fan runs	Outdoor unit in a defrost cycle, a blocked or iced outdoor coil, low refrigerant, a faulty reversing valve or sensor
Cold air blowing in heat mode	Remote set to cool or auto, a reversing valve fault, a control board or sensor fault
Water dripping from the indoor head	Blocked condensate drain or tray, a head that is not level, dirty filters causing the coil to freeze and then thaw
Ice on the pipes or indoor coil	Very dirty filters, low airflow, low refrigerant from a leak
Error code on the display or flashing lights	A sensor, fan motor, communication or refrigerant fault; the code narrows it down
Unit trips the breaker or will not power on	Electrical fault in the unit, the wiring or the circuit
Rattling, grinding or a loud outdoor unit	Loose panels, a failing fan motor or bearing, a compressor problem

Some of these are normal. Most reverse cycle units stop blowing warm air for a few minutes during a defrost cycle on a cold, damp morning, and the outdoor unit may steam while it does. If warm air returns within about ten to fifteen minutes, that is usually the unit working as designed. If it never comes back, note it for the technician.

What can I safely check before booking a repair?

There are a few checks an owner can do without tools and without taking any cover off:

1. Remote and mode. Check the remote says heat, not cool, auto or dry, and that the set temperature is above the room temperature in winter. Replace the remote batteries if the display is faint.
2. Filters. Lift the front panel of the indoor head and look at the filters. If they are grey and matted, wash them as the manual describes and let them dry before refitting. Clogged filters cause icing and weak airflow.
3. Switchboard. See whether a breaker or safety switch has tripped. You can reset it once. If it trips again, leave it off and tell the technician.
4. Outdoor unit. Make sure nothing is blocking it: leaves, a bin, a garden cover, long grass or a build-up of ice on the fins.
5. Isolator. Check the isolating switch near the outdoor unit is on.

Stop there. Do not remove covers, touch wiring or try to add gas. Under Australian Refrigeration Council rules, even routine service work on an air conditioner counts as licensed work, because opening the system can let refrigerant escape, and that applies even to a unit that has already lost its gas. See the ARC list of work that requires a licence. Those licences come from the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989, a federal law.

What details help a technician diagnose the fault?

A technician who knows the system before arriving can bring likely parts and give you a better idea of the cost. Collect these before you describe your air conditioner fault:

• The make and model number from the sticker on the side of the indoor head and on the outdoor unit
• The error code or the pattern of flashing lights, written down exactly or photographed
• A photo of the indoor head, the outdoor unit and the pipe cover running between them
• Roughly how old the system is and when it was last serviced
• When the problem started and whether it is constant or only at certain times
• How it behaves in heat mode and in cool mode, since some faults show in one mode only

If the unit has not been serviced for a few years, the technician may suggest a clean as part of the visit. Routine cleaning on its own is covered on the air conditioner servicing page.

What is the difference between a minor repair, a major repair and a regas?

Minor repairs are jobs like clearing a blocked drain line, replacing a sensor, fixing a loose connection, replacing a remote receiver or fitting a new fan capacitor. The Melbourne guide range for a minor repair is $160 to $525.

Major repairs and regas include replacing a fan motor, control board or reversing valve, finding and fixing a refrigerant leak, and recharging the system with refrigerant. The Melbourne guide range for a major repair or regas is $315 to $1,250.

These are Melbourne metro guide ranges that include GST. A business travelling around the Latrobe Valley may price differently, and the real cost depends on the fault, the part and how hard it is to reach.

On a regas, a careful technician will want to know why the gas is low. A sealed system should not need topping up. If it is short, there is a leak somewhere, often at a flare joint near the outdoor unit or at the indoor coil. Adding gas without finding and fixing the leak means paying again later. Ask the technician to explain where the leak was and how it was repaired.

When is it better to replace than repair?

There is no fixed rule, but these points help:

Lean towards repair	Lean towards replacement
The unit is under about ten years old	The unit is old and parts are hard to get
The fault is a sensor, drain or fan part	The compressor has failed
It has worked well until now	It has needed several repairs in recent years
The quote is a small share of a new unit	The repair quote is close to the cost of a new unit
It heats the room adequately on cold days	It never kept the room warm, even when working

If the answer leans towards a new unit, the split system replacement page covers changing an old split for a new one. All the price bands used on this site are set out side by side in the Traralgon heating and cooling cost guide.

What will a careful repairer check, and what will they refuse to do?

A careful technician will:

• Check the electrical supply and the circuit before opening the unit
• Read the fault code against the manufacturer’s service information
• Check refrigerant pressures with gauges rather than guessing
• Look for oil stains at joints, which often mark a leak
• Test the system in both heat and cool mode before leaving

They will refuse to top up refrigerant on a system with an unfound leak without telling you, and they should not vent refrigerant to the air. Show them the licence card, and you can check it yourself on the Look for the Tick licence search.

Who fixes an electrical fault on an air conditioner?

If the fault is in the wiring, the circuit or the switchboard rather than inside the unit, a licensed electrician needs to do that part. Some air conditioning businesses employ one, others bring one in. The about page explains how to check an electrician on the Energy Safe Victoria public register, along with refrigerant and gasfitting licences.

Next step: describe the fault

To send an air conditioner repair enquiry, include:

• Make and model of the indoor and outdoor units
• The error code or flashing light pattern
• When the problem started and anything that changed around then, such as a storm, a power cut or a recent service
• What the unit does in heat mode and what it does in cool mode
• Your suburb, and photos of both units

The business that picks up the enquiry will contact you to arrange a time and price the repair.
