The major benefit is a comfortable climate-controlled indoor environment all year round. An air conditioning unit has a number of functions including heating, cooling, dehumidifying and fan only. The dehumidifying function is particularly beneficial for those with asthma.

The cost of air conditioning depends on a variety of factors, but here’s a breakdown to help you understand the main drivers:

1. Type of system:

  • Split systems: Powerful and efficient, cool multiple rooms well, $1,500-$4,000+gst for supply and installation.
  • Ducted systems: Cool whole home, $6,000-$18,000 for supply and installation.

2. Size and capacity: Bigger units for larger spaces cost more. Consider the square footage you want to cool.

3. Brand and features: Different brands and models offer varying features (energy efficiency, smart controls, noise level) impacting price.

4. Installation complexity: Complex installations (ductwork) increase labor costs.

5. Location: Prices can differ based on your location and our availability.

At D.E Air conditioning we can supply and fit a large range of air conditioning units to suit your budget. We have entry branded air conditioning units for a small bedroom to entire ducted unit for the entire house. All air conditioning units have a 5 years parts and labour warranty for domestic applications and various commercial warranties available. 

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 book in a FREE consultation with D.E Air conditioning to discuss your requirements.

The most common residential split-system air conditioner is an air conditioning unit made up of two units – an outside unit, the compressor, and an inside air outlet unit, usually referred to as the “wall hung head unit”. The two units are connected by pipes that carry refrigerant. An alternative to the standard unit is the multi-split system, which has multiple indoor units connected to a single outdoor unit. A split-system air conditioner can be used for cooling and heating.

The unit itself come in 2 parts and is built to cool more areas. The indoor unit is installed in the ceiling cavity of your home. The evaporator coil within the indoor unit conditions the air from the room. The fan inside the indoor unit then circulates the conditioned air back into the room. The outdoor unit is installed on the outside of your home. It is connected to the indoor unit via interconnecting pipe work which carries the refrigerant. The compressor in the outdoor unit circulates the refrigerant between the indoor and the outdoor units.

Correct installation is vital to ensure the efficient 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.

How incredibly painful is it when in the middle of summer or winter your air conditioning system fails on you! We know you need help fast and to try to fix the problem as soon as possible. heres a few things to get you started.

  • Reset the system (sometimes it could just be a small fault, try resetting the system at the breaker for 5 mins and turn back on and see how it goes)
  • Clean your filters, this is one of our most common fualts being a blocked or dirty filter.
  • Write down the Model number of the outdoor machine and what fault code if coming up on your controller.
  • Contact us to discuss what the problem may be.
