Frequently Asked Questions

Here's what we get asked quite a bit

How often do I clean my return air filter?

Every 3 months. A general indication is when the filter light flashes, but depending on the environment or the air purity, in a normal domestic situation once every season is adequate.

I've cleaned my air filter but the light won't go off?

Press the reset button on the controller. On wall splits and floor consoles, remove the grill and press the reset button.

How oftern should my air conditioner be serviced?

Once a year, on average.

How long will my air conditioner last?

Provided it is well maintained and regularly serviced, a good quality unit should last well past its 5 year warranty.

I have ducted air conditioning and the air only comes out in part of the house?

Ducted systems can be designed to operate in zones, heating or cooling different areas of the property at a time. Check that the zone switch for the area you wish to cool or heat is turned on.

How do I handle an overloaded air conditioner?

Well your air conditioner has safety mechanisms that cut in when the coil on the back of your outdoor condenser gets too hot. The pressure builds up in your system and your unit cuts off on high head pressure.

So some simple things you can do to help prevent this occurring are the following: * The first thing is to make sure there is shade over your air conditioner, while still not restricting the airflow around the unit.

There is a red light flashing on my air conditioner?

There will be a code at the bottom left of the screen, find out what it is and arrange for a service.

My air conditioner is not cold, but no red light flashing?

There is no fault. Check to make sure that you have it on cooling (will have a snow flake symbol. The Sun means heating). Press button to the left of the fan button till you see a snow flake.

How does an air conditioner work?

Air conditioners and refrigerators work the same way. Instead of cooling just the small, insulated space inside of a refrigerator, an air conditioner cools a room, a whole house, or an entire business.

Air conditioners use chemicals that easily convert from a gas to a liquid and back again. This chemical is used to transfer heat from the air inside of a home to the outside air.

The machine has three main parts. They are a compressor, a condenser and an evaporator. The compressor and condenser are usually located on the outside air portion of the air conditioner. The evaporator is located on the inside the house, sometimes as part of a furnace. That's the part that heats your house.

The working fluid arrives at the compressor as a cool, low-pressure gas. The compressor squeezes the fluid. This packs the molecule of the fluid closer together. The closer the molecules are together, the high its energy and its temperature.

The working fluid leaves the compressor as a hot, high pressure gas and flows into the condenser. If you looked at the air conditioner part outside a house, look for the part that has metal fins all around. The fins act just like a radiator in a car and helps the heat go away, or dissipate, more quickly.

When the working fluid leaves the condenser, its temperature is much cooler and it has changed from a gas to a liquid under high pressure. The liquid goes into the evaporator through a very tiny, narrow hole. On the other side, the liquid's pressure drops. When it does it begins to evaporate into a gas.

As the liquid changes to gas and evaporates, it extracts heat from the air around it. The heat in the air is needed to separate the molecules of the fluid from a liquid to a gas.

The evaporator also has metal fins to help in exchange the thermal energy with the surrounding air. By the time the working fluid leaves the evaporator, it is a cool, low pressure gas. It then returns to the compressor to begin its trip all over again.

Connected to the evaporator is a fan that circulates the air inside the house to blow across the evaporator fins. Hot air is lighter than cold air, so the hot air in the room rises to the top of a room.

There is a vent there where air is sucked into the air conditioner and goes down ducts. The hot air is used to cool the gas in the evaporator. As the heat is removed from the air, the air is cooled. It is then blown into the house through other ducts usually at the floor level.

This continues over and over and over until the room reaches the temperature you want the room cooled to. The thermostat senses that the temperature has reached the right setting and turns off the air conditioner. As the room warms up, the thermostat turns the air conditioner back on until the room reaches the temperature.
