1.How to choose the best air conditioner.

Use these top tips to help you choose the best air conditioning system for your home or business:

Type: For the most effective air conditioning you will be looking for a wall mounted split air conditioning unit or central air conditioning, rather than a portable standalone unit.

EER: The Energy Efficiency Ratio (EER) conveys how energy efficient the air con unit is. The higher the rating, the more efficient the air con system.

Extras: Handy extra features to look out for are:

1. a variety of fan speeds so that you can vary the rate of cooling.
2. a remote control, timer and sleep or night mode are useful practical extras. Night mode will prevent the problem of waking cold if the temperature drops during the night, which it often does in Canberra.

Meanwhile, with a timer function you can set your air conditioner to switch on and off at the times that are convenient for you. An easy way to solve the problem of whether to sleep with the air conditioning on or not. Simply get one with a timer, then it can switch itself off automatically.

LG Ducted Air Conditioners Canberra

What the LG ducted air conditioner range lacks in variety it makes up for with the wide range of impressive features built into each air conditioner. Sporting LG’s inverter technology, anti-corrosive treatment, and External Static Pressure controls among other things, the LG ducted systems come with all the features you could possibly need.


Common LG Air Conditioner Features

No matter the model you choose, each one sports an ease of installation, energy efficiency and flexibility so you can install the ducted AC to suite your home. New low/mid-static ducts provide ideal solution for installation in limited space, with heights of just 190mm or 270mm. LG air conditioners run at 31 decibels, quieter than a library. Variable Airflow Technology monitors the dampers so that only the required amount of air is discharged into the space. This helps to lower energy consumption by up to 20%.

Power figures for the entire LG range go from just 6kw all the way up to 20ks, easily enough for an entire house. Expect the biggest ducted systems to cost over $10, 000. The advantage the LG range has is that the fan/motor part assembly and heat exchanger assembly can be separated, allowing the installation of the indoor unit in two parts before final assembly, saving you time and money.

LG air conditioners have received numerous CHOICE awards for product quality over the last few years, and also come with a 5 year parts and labour warranty.

With the preliminary information in hand, let us explore what you can expect from an LG ducted air conditioner.


What can I expect from LG ducted air conditioners?

  • Optional Wi-Fi Control – so that you can control your unit with your Smartphone, even when you’re not at home
  • Improved Energy Efficiency – The latest Inverter technology from LG helps to lower cooling costs in the summer

Which Air Conditioner is good to use during bushfire smoke conditions in Canberra and how to improve air quality

Below are some useful links get more information and keep yourself and loved ones safe.

Canberra Air Quality – ACT Health >

Emergency Services Agency updates >

How to protect yourself and others from bushfire smoke – Australian National University >

See how global warming has changed the world since your childhood – Australian Broadcasting Corporation >

The season of a smoky Canberra might be drawing to a close, but what about next time this happens? You don’t want to be at the mercy of the weather and a shift in wind patterns that bring in smoke that unhealthy for you to breathe in.

The Earth is slowly warming and wildfires are expected to become more prevalent in the coming decades. According an article published by the Australian National University breathing smoky air can irritate airways, and poses an especially serious risk to:

  • People who have heart or lung diseases, such as coronary artery disease or asthma.
  • Older people due to their increased susceptibility to heart and lung diseases.
  • Young children whose airways are still developing, and breathe more air, proportionally speaking, than adults do.
  • Pregnant women

What is in wildfire smoke?

Wildfire smoke is a shifting blend of gases and particles, including carbon dioxide, water vapor, carbon monoxide, hydrocarbons and other organic chemicals, nitrogen oxides and trace minerals. The worst part about smoke are the particulate matters, the tiny bits of feathery ash and dust-like soot, mostly invisible to the eye.

A lot of the particulate matter is less than 10 microns wide, known as PM 10. (A human hair is about 60 microns wide).

Avoid making your indoor air worse

You need to start by keep your windows and doors shut.

Your air conditioning unit is effective as a smoke filter, provided your house is well sealed against drafts and external air. Try to maintain the air quality inside by keeping openings secured and don’t smoke, burn candles, vacuum, or use your oven to avoid stirring up particles already inside your home. Turn bathroom fans and window units off.

Bathroom fans and window box fans commonly pull outside air into your home, so they should be shut off during smoky conditions.

Can I use my Air Conditioner while there is a lot of smoke outside?

In most cases, your home air conditioner recycles the air within the home. Every time the air passes through your air conditioning filter, the air is cleaned, and because there is no polluted air entering your home, the air remains quite clean and safe. If your air conditioner has a ‘Fresh Air’ function, you need to turn this off. This feature allows air from outside to enter the air conditioning system, any air drawn from outside risks bringing in bushfire smoke and the harmful contaminants you want to keep out.

Don’t use an evaporative AV during smoky conditions Evaporative systems draw air in from outside the house and push it through water-laden filter pads for cooling draw in other contaminants, such as smoke particles.

Now that you know what Air Conditioner unit you can’t use during a bushfire, what AC units can you use?

If your AC is a split system, an inverter or ducted system, you can use any of these when there is a lot of smoke present. While your outside unit expels a lot of hot air, that air isn’t coming from inside your home and being replaced with outside air. Air conditioners are heat exchangers. They use a closed coolant system to absorb heat from the air inside your home and use powerful fans to push a lot of outside air over that same coolant system, suck out the heat, and exhaust that heated air back outdoors.

If you have a heating system (gas furnace) or a cooling system you’re not currently using, turn the fan on at your thermostat. For the best possible air quality in your home, consider installing an electrostatic whole home air filter or heat recovery ventilator, which provides you with a continuous stream of fresh air.

A Split System –  the way split system air conditioning works is that the condenser sits outside and manages the heat expulsion, while the head unit inside the house re-circulates and manages the airflow and temperature. The condenser only manages external air so it has no capacity to draw smoke into your house. Having an inverter in your in your AC allows large units to ramp down and use little power when their load and capacity is not required.

Make sure you have the right filter Start by making sure you have a fresh filter for your system with a backup ready to go. To choose the right filter, consider the Minimum Efficiency Reporting Value (MERV) rating. Filters that are MERV 13-16 are expected to reduce indoor particulars as much as 95%. Filters with a High Efficiency Particulate Air (HEPA) rating, (or MERV 17-20) will reduce particulates in your home even more. You might also consider an air filter with activated carbon. Carbon air filters are designed to filter volatile organic compounds (VOCs) from gases in your home through a bed of activated carbon (also called activated charcoal).



Error fault code on Mitsubishi Electric ducted air conditioning systems

UF / UP / U6 fault code on Mitsubishi Electric ducted systems

A common fault on Mitsubishi Electric ducted systems is the UF, UP or U6 error code. This fault code commonly represents a fault within the Outdoor Power PCB, Compressor electrical circuit or Compressor bearings. Of these 3 similar errors codes, the most common to see is the U6, UP or UF. This will be displayed on your wall controller after the unit tries to run 10 times in a row without success.


Mitsubishi Electric define UF / U6 / UP faults as follows:

UF – Compressor overcurrent interruption (when compressor locked). Abnormal if overcurrent of DC bus or compressor is detected within 30 seconds after compressor starts operating.

U6 – Power module abnormal. Check abnormality by driving power module in case overcurrent is detected. (UF or UP error condition).

UP – Compressor overcurrent interruption. Abnormal if overcurrent DC bus or compressor is detected after compressor starts operating for 30 seconds.

Common issues that can cause U6 / UF / UP faults

  • Failure or the Power PCB in outdoor unit
  • Electrical failure or fusion of Compressor
  • Seized bearings in the Compressor
  • Disconnected/broken wiring to the compressor
  • Closed service valves at outdoor unit
  • Low voltage at outdoor unit
  • Tests to determine faulty components


P8 fault code on a Mitsubishi Electric unit

One of the most common issues seen with older fixed speed Mitsubishi Electric air conditioning units is the P8 fault. The P8 fault is quite generic and can be the front for a multitude of different issues.


What causes the P8 error code?

The P8 fault can mean many things when it pops up on your Mitsubishi Electric wall controller. The P8 fault is activated when the indoor coil sensor does not change temperature for a set amount of time after the compressor is (or should be) switched on. Put simply, if the indoor unit does not get hot or cold within a predetermined time frame (approx. 9 minutes), the indoor unit thinks the compressor is not running and faults on P8. The reason for the compressor not running can be anything. To further diagnose the unit you will need to look at the outdoor unit PC Board.


What can a P8 fault mean on your Mitsubishi Electric air conditioning system?

On older fixed speed Mitsubishi Electric units, the P8 error code generally points to a fault with the outdoor unit. The outdoor faults on your Mitsubishi Electric unit will be displayed on the Outdoor PC Board. These faults are shown via small red LED lights on the PC Board. If the lights are Solid, this is not a fault and represents the units operating condition. If the light is flashing, a fault is present.

The following faults/conditions are represented by the numbered LED lights on the Outdoor PC Board:

Solid (No fault) Flashing (Fault)
LED 1 – Compressor Command Reversed Phase Detect
LED 2 – Heat Command Open Phase Detect
LED 3 – During 63H1 Operation Pipe Sensor Short/Open
LED 4 – Compressor ON HP Switch(63H2)Operation
LED 5 – Outdoor Fan ON O/L (51CM) Operation
LED 6 – 4 Way Valve ON Thermal Switch (26C) Operation
LED 7 – Bypass Valve ON Thermistor (TH3) Overheat Protection
LED 8 – Crankcase heater ON Defective Input

Common Error Fault Codes in Air Conditioners

Whether you have a ducted air conditioner, split system, multi-zone or a commercial air conditioning unit, you may see a dreaded error code appear on your master controller. Some may be an easy fix, such as simply resetting your air conditioner and clearing the onboard memory while others require professional assistance.

In this article, we will go over general reasons for receiving an error code, general air conditioning faults, UF / UP / U6 fault code on Mitsubishi Electric ducted systems and common LG split system faults.

There are many possibilities as to why your master controller may be displaying error codes or why your system is not responding.

Potential reasons across a range of air conditioners include:

  • The system needs re-gassing
  • Old age (wear and tear)
  • Technical faults
  • Unforeseen weather events
  • Animals damaging the system in the roof or the outdoor unit
  • Air conditioner not switched on at the control
  • The circuit breaker has tripped
  • Vermin may have chewed through controller wiring
  • Blown council service fuse
  • Your local power supplier may be doing works to your areas power supply
  • Internal fault in the air conditioner
  • Defrosting
  • Compressor delay after a restart
  • Delayed fan start on heating


If moulded case circuit breakers or earth leakage circuit breakers have tripped, do not reset the breaker immediately without first checking, or have your technician check for any problems with insulation of equipment. Resetting breakers without a check of insulation may cause damage to equipment.

By ‘resetting’ your air conditioner, what we mean is deleting the air conditioners on board memory to try a fresh restart. While not always successful, it is the first step in trying to save money with a service call. Some faults are caused by lightning strikes, blackouts and brownouts or various power fluctuations caused by any number of things and just may be the cause of your air conditioner shutting down for safety reasons.

How to reset your air conditioning error codes. (Note: we are NOT resetting circuit breakers that have tripped.)

Isolator Switch Master Reset. Go to your outdoor unit.

  1. Locate the isolator switch on the unit or on the wall beside the unit, which looks like a commercial on/off switch.
  2. Turn the switch off and leave it off for an hour.
  3. Turn the isolator switch back on after an hour.
  4. Turn the unit back on from the master controller and see how the system runs.

Turning off the isolator switch will cut the power from the switchboard and clear the memory of the air conditioning functions it was doing beforehand.


General Air Conditioning Error Codes (Fault Codes)

There are many hundreds of error codes that are used within the air conditioning industry, and they are mostly different across different manufacturers and across their different models, and we won’t list them all. Below is a short list of common error codes from a couple of major air conditioner manufacturers.

This is a general summary of the error codes you may see on your air conditioner.

Error codes A0 to AJ, go from an indoor error of external protection device, to a PCB defect, to a malfunction of EEV, the indoor fan motor lock is overloaded and a malfunction of capacity set device.

C3 to CE error codes range from a malfunction of either the drain thermistor, air thermistor, moister sensor, discharge air thermistor, remote control thermistor or the radiant heat sensor, and all the way up to indoor lower louvre limit switch motor.

E0 to E9 error codes range from outdoor activation of outdoor safety device, an outdoor PCB defect, an outdoor compressor motor lock, an outdoor compressor start up error, Outdoor Fan motor lock – Overload up to Outdoor Malfunction of EEV.


F3, F6 and FC error codes.

Error Code Meaning
