Confirm that the mode is correct and that the “sun symbol” is showing on the screen of the remote.
If it does not display the heat mode it will not be able to heat the room.
Please note that by setting 30°C on the remote, you are setting the desired temperature. The temperature set by the remote regulates the temperature in the room.

Check the display on the remote displays the “icicle symbol”, if it is set to the wrong mode, it will not cool.
Please note that by setting “16°C” on the remote is the desired room temperature. It does not mean that colder air is coming from the unit.

Your air conditioning unit will periodically cycle to get the ice build-up on the condenser to reduce. While this is happening, the unit will not provide cooling. The unit needs to cycle in order to retain efficiency and allow the coils to function correctly. If your air conditioning unit does this on a continuous basis you will need to call a technician in order to test the unit and assess the fault.

This probably means compressor is malfunctioning. Call a technician. more than likely it is the compressor or requires a capacitor to be refitted.

An inverter air conditioner has a ‘soft start’ compressor that slowly speeds up until the room reached your selected temperature. Once it achieves the “set point” it slows in order to maintain the temperature. Inverters avoid the stop-start of a fixed speed compressor, saving between 18%-35% on electricity usage of a fixed speed compressor.

A fixed speed unit has a compressor that runs at a constant speed. It switches on and off each time it is 2°C above or below the set temperature. It draws a large amount of current each time it switches on.

An air conditioner should not require re-gassing if it has been installed correctly. The piping that runs in the unit should be a sealed system, the gas in the system has a dual purpose, to transfer heat from indoor to outdoor and to lubricate the compressor.

Units should still be serviced at least once a year to guarantee efficient operation.

Most air conditioners will give you 3kW of output for every 1kW of input. The kW rating on an air conditioner is hourly, so compared to a fridge will be more expensive to run. However, when compared to a heater with an element, an air conditioner is a far more efficient way to to heat or cool an area.

Avoid switching the unit back on again. The unit is switching itself off to protect the compressor. This normally happens when the compressor is over-heating. There will usually be an error code displayed on most units either on the remote, or on the unit itself. Your manual should indicate what the various status codes mean. If not assessed and repaired, an error could lead to severe damage.

Air conditioners work by directing heat from one place to another. When it is cold outside, it takes longer for the unit to find warmth in the air and transfer it inside the room. Most air conditioning units will have an range indicated in the operation manual (usually about -5°C) but this varies. Once the unit has warmed the room up, it will maintain the heat quite well, it may just take longer to reach this point in cold weather.

Dirt collecting in an air conditioner’s drain pan can occasionally block the pipe causing moisture from the coils to build up and overflow from the pan.

A short-term solution is to place your mouth over the exit pipe and blow swiftly into the pipe. This will dislodge the sediment and start the drain pan flowing again. This will not work when multiple units’ drains are connected.

An extended drain pipe may require a high pressure burst to dislodge the blockage. This may cause spray on the interior of the unit and it should be covered with a towel or plastic to avoid this.
Air conditioners that are serviced regularly usually do not have this problem. you may also find that units that are not serviced often enough may block as when they are cleaned, the large amount of dirt dislodged at once now cannot flow through the drain and causes the outflow pipe to dam up.

When in doubt call an approved technician.
