Frequently Asked Questions

Air Conditioner Size Selection Guide

Your air conditioning sizing requirements will vary subject to a number of factors. These factors include the aspect positioning of your house, the material the house is made of such as brick veneer, double brick or weatherboard. The location and size of windows and the covering on these windows and whether the house is insulated has a large bearing on the sizing. These factors combined with the region you live in can vary air conditioning requirements by up to 20% between a house in Northern and Southern Australia.

To be sure you purchase the unit that best suits your situation we recommend you discuss your specific requirements with Apex aircondinioning.

Q: What are the benefits of Air Conditioning?

The major benefit is to provide a comfortable environment throughout the year. An air conditioning unit has a number of functions including heating, cooling, dehumidifying and fan only. For instance temperature can be set as desired, when dehumidifying the unit will get rid of moisture in the air without dropping the room temperature, being beneficial for those with asthma.

Q: What are some types of air conditioners available?

SINGLE ROOM AIR CONDITIONERS - One-piece unit, which must be installed in an external wall or window. These can be available in Reverse Cycle or Cooling only.

SPLIT SYSTEMS – Generally two piece units consisting of an Indoor and Outdoor Unit. Split Systems are available as Reverse Cycle or Cooling only. These are available in either fixed speed or inverter. Inverter units are quiter , economical and energy efficient

DUCTED SYSTEMS - Ducted air conditioners are able to condition whole or part of a house. This is a highly specialised area and should only be undertaken by a qualified contractor.

MULTI SYSTEMS - Multi systems enable you to connect up to four indoor units to a single outdoor unit. The series includes a wide variety of indoor units, so it is easy to select a model that blends in unobtrusively and allows you to create a decor that matches your personality. A single compact outdoor unit allows you to make more efficient use of available space.

For example having individual, indoor units in different rooms (ie living, study & bedrooms), allows for them to be controlled independently to better match your needs.

Q: Maintenance?

Regular maintenance ensures that your airconditioning will work when you need it most & keep on working throughout the years.
Benefits of regular maintenance include:

• Reduces breakdown costs.
• Keeps unit running efficiently which inturn saves on energy consumption.
• Maximises life cycle of air conditioning unit.

Q: What are the installation requirements?

Correct installation is vital to ensure that performance of the unit. In the installation process, allowances must be made for drainage from the indoor unit on cooling mode and outdoor unit on heating mode. Positioning of the indoor unit is important and should not inhibit the flow of air, where possible the unit should be placed centrally on a wall directing the airflow to the centre of the room. With the outdoor unit, it should be positioned in a well-ventilated area on a solid footing and must be easily accessible for servicing purposes. Take into account that installation faults may void manufacturer warranties, and so only qualified air conditioning installers should carry out this work.

Q: How about Insulation?

When insulation is installed significant savings can be made on the running costs of air conditioning and a lower wattage unit could be installed, ie. Saving on the purchase cost.

Q: What are some of the factors to consider when buying and installing split air conditioners ?

Make sure the unit you purchase is the correct size, allowing the unit to cycle off when the correct temperature is reached. This allows for the compressor to switch on and off as required rather than running continuously.

Set your thermostat so that you feel comfortable rather than cold. Most of us feel comfortable at between 22 and 24 degrees in summer. Remember that in summer you will be dressed in summer attire.

Consider insulating the ceiling so that you may be able to use a smaller capacity unit.

Make sure the unit is securely mounted to avoid unnecessary vibration. Mounting through the wall will generally give a more secure install than through glass.

Maintain the filters of your air conditioner on a regular basis and in the case of split systems, have your unit serviced by a qualified tradesperson at least every two years depending on the environment the unit is installed in, some units require a professional service once a year.

Q: What are some of the factors to consider when locating your outdoor unit?

Be sure to have maximum clearances around the outdoor unit, to minimise the chances of hot air, being recirculated back into the outdoor unit; especially if there is a wall directly opposite, as this can cause the unit to over heat and fail especially on hot days.

Is the condensing unit going to be located under a carport or roofed entertainment area? These areas are more reflective of sound.

Maintain the filters of your air conditioner on a regular basis and in the case of split system/ducted/multi-systems have them serviced by a qualified tradesperson at least twice a year, depending on the environment the unit is installed in.

Q: General Information of Interest

Horsepower is a measure of the rating of a compressor and does not relate to the cooling capacity of an air conditioner. Use watts or B.T.U.

Placing the outdoor unit in direct sunlight makes the outdoor unit work harder.

In cooling mode remember that the method of sizing most commonly used is designed around a maximum differential of around 10 degrees.

Most of us feel comfortable at between 24 degrees and 26 degrees and at a humidity level of 60% to 75% in summer and 55% to 70% in winter.

Over sizing is just as bad as under sizing as the unit may cycle off before the appropriate amount of dehumidification has occurred.

Installation is important. If a unit fails due to a problem with the installation (faulty flare connections etc.) it will not be covered under the warranty.

Location of the outdoor unit must be easily accessible.
