Frequently Asked Questions

Air Conditioning F.A.Q.

 What does 'Reverse Cycle' and 'Split System' mean?

A split system air conditioner comprises two pieces – the outdoor unit which sits outside your home and the indoor unit, commonly wall mounted inside the home. Reverse Cycle means the system can provide both heating and cooling. Multi-Head Systems, Ceiling Cassettes, Under Ceiling Units and Cooling Only models are available.

 What is Back-To-Back Installation?

The indoor and outdoor units are placed on opposite sides of the same wall. This reduces the amount of copper pipe run required to connect the two units.

 Do I need ducted air conditioning?

Ducted air conditioners are recommended if you wish to condition most areas in the home, if split systems are not practicable, or if you prefer the more discreet look of the outlet registers. The indoor fan coil unit is situated in the ceiling space and is connected to the outdoor condensing unit. Individual outlet registers are situated in each room (generally in the ceiling) with the air conditioning controlled by a central controller pad.

 How are the air conditioning units controlled?

Zoning allows you to turn on and off the air conditioning in certain areas of the house. This is done through the use of zone controls in the ductwork situated in the ceiling space.

 What is an Inverter Air Conditioning System?

An Inverter system uses a variable speed compressor, which allows variation in the cooling or heating capacity of the air conditioning to suit indoor conditions. Inverter units more economical & efficient to operate as well as quieter than the standard fixed speed systems. Both ducted and split systems are available with Inverter compressors.

 What size unit do I need?

This is determined by the size of the area, the aspect, whether the home is insulated, the amount of glass and the heat load generated from the number of people occupying the area.

Please email plans (pdf format) to sales@graftonair.com.au, along with any queries or comments to help us assess your requirements.

 What is the operating cost?

Reverse cycle air conditioning is the most energy efficient method of heating and/or cooling your home or office. Operating costs are determined by how long the air conditioning system is running and the size of the area to be conditioned.

It is essential that the correct size unit is installed. An undersized unit will be significantly more expensive to run taking longer to heat or cool the area effectively.

See our energy saving tips for more information on keeping running costs to a minimum.

 How long does it take to install a new Air Conditioning Unit?

Most residential installations of a split system generally take 4-6 hours. The installation of a ducted system generally takes 1-2 days. We can arrange the installation at a time convenient to you. All installation labour carries a 12 month warranty.
