Ducted Evaporative Air Conditioning
Evaporative cooling is an entirely natural method of cooling, using only air and water - to cool air through the simple principle of evaporation of water.
Ducted Reverse Cycle Refrigerated Air Conditioning
Ducted Refrigerated air conditioners consist of a compressor, fan and heat exchange coil and use a refrigerant to cool or heat the air.
Hot air is drawn into the cooler and passes through water-moistened pads or specifically designed cells.
Some of the water evaporates, absorbing the heat as it does so, and cools the air.
This cooled air is then blown into home which forces hot air out through open windows and doors.
Ducted evaporative air conditioning units are positioned on the roof with ducting throughout the roof space to direct air into the rooms of the home.
Refrigerated air conditioners have two separate mechanical parts, an outdoor compressor and an indoor unit/fan coil.
The outdoor compressor unit compresses refrigerant gas into a liquid state to allow the refrigeration effect to take place, exactly the same way as does your home refrigerator.
The compressed gas is transferred into the indoor unit.
The indoor unit basically consists of a fan and a heat exchange coil.
The fan is connected and then controlled by a room installed thermostat that draws the air from inside the home, passes it through a filter and then recirculates throughout your home approximately 10 times each hour.
Ducted refrigerated air conditioning units are normally positioned inside the roof, as well as an inverter unit outside the house (usually on a side wall) with ducting throughout the roof space to direct air into the rooms of the home

Evaporative air conditioners generally use much less energy to cool than refrigerated air conditioners. They are the cheapest form of whole of home cooling. They will run from as little as 3 cents per hour for your whole home. The low running costs and low installation costs are a big reason why evaporative cooling is very popular.
Ducted reverse cycle air conditioning is generally much more expensive to run than evaporative cooling. A ducted system cooling a whole home may cost more than $1 per hour to run. This amount can be significantly reduced through the use of smart zoning to reduce energy wastage.
All evaporative air conditioners use water to produce the cooling effect.
The amount varies with the size of the air conditioner, the amount of cooling selected, and the ambient conditions.
Braemar and Breezair units have unique, market leading water management features which keeps the system clean by minimises water loss through dumping
Refrigerated units do not use water to cool.
Most effective in hot & dry climates

Evaporative air conditioners constantly draw clean fresh air into the home rather than circulating the air.
Because water is used in the cooling process, the air will have added moisture.
Refrigerated air conditioners continually recirculate the air.
This cooling type removes moisture from the air as it cools.
It can have a drying effect
Windows or doors must be left open to allow the hot air to be pushed out and replaced with cool fresh air.
Because the cool air is recirculated, windows or doors need to be closed to prevent the cool air from escaping.
An environmentally friendly option, gas heaters have lower greenhouse emissions compared to electric heaters and inefficient solid fuel heaters. Correct sizing and zoning of your system will minimize wastage and impact on the environment.
Electric heaters have higher greenhouse emissions compared to gas heaters. Correct sizing and zoning of your system will minimize wastage and impact on the environment.
The performance will vary depending on quality of unit. As a general rule, a good quality evaporative cooler is capable of bringing the temperature down by a maximum of approximately 12°C from the outside temperature.
Sizing your unit correctly, and purchasing a good quality brand will optimise performance.
Our expert team will show you how. Evaporative cooling works best in hot, dry conditions. These conditions are typical to Victorian Summers.
Is capable of bringing the temperature down by a maximum of approximately 25°C (45F) from the outside temperature.
Note: this is largely dependent on the outside air temperature and how long the system has been running and the correct sizing of the system to cool the required area.

Adrian was very polite and knowledgeable about heating. He was respectful of my budget, measured and calculated exactly what I would need and the installation all went smoothly. Highly recommended!
