Air Conditioning Australia - Information
About us
Air Conditioning Australia...
This website has derived from a number of sources and has come about for a number of reasons. As you may have noticed the Internet is huge, and gets bigger by the hour. But more so, the content you get back from certain websites, when doing an innocent search on , eg: http://www.google.com.au can be somewhat disappointing.
As air-conditioning engineers, we decided to create our own small website, and we started researching, air-conditioners , together with what resources were available to us on the internet.
WOW were we disappointed... most of the content we found was totally irrelevant, pointed us to shopping websites, or shopping portals, and had zero or little regard to the search we were doing. Which meant little or no help to our customers.
We are a small family business, based in 2 strategic locations within Brisbane. Logan and Dayboro. This allows us to easly, service all compass points within Brisbane, both efficiently &economically.
Air Con Installations.
- We install from 7am - 5pm Monday to Friday
- Saturdays 8am-12 noon
- Sundays closed
Let's face it, if you are looking for Air Conditioning, you want to know, what is available, and how much it is going to cost. That is what we set out to do on here. Clear pricing, easy to follow, easy to order. We stock everything we sell, and generally install a split system in about 2 hours, excluding electricals.
We also do not mind installing your own air-conditioner. The only premise, is it must be brand new. We do not install second hand machines, or re-positioned machines, as we cannot guarantee the integrity of the unit.
Our Air Cons we supply
The air conditioners we supply, are fully warranted for upto 5 years, on major components. We are also service agents for our own air cons, so if it goes wrong, we have the parts to fix it ( in 90% of cases all parts are in stock ) Unlike other companies, who pass you to a generic call centre in " The backend of beyond " and leave you waiting there for days and weeks on end, waiting for parts to arrive from China... Our engineers, can normally fault find the issue over the phone, and bring the parts with them on service call.
Also our Air Con units are proven, having been installed by us in thousands of homes. Why take chances, and install an Air Con, that has no pedigree, just because it maybe $30 cheaper in a magical SALE??
All in all, we are just a friendly family business, that does what it says on the tin. " Value | Quality | Service "
How air conditioners work ?
Air conditioners employ the same operating principles and basic components as your home refrigerator. An air conditioner cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.
A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils. The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling your home or small business.
The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the air flowing over the condenser's metal tubing and fins.
What type of Coolant should I look for?
Most air-conditioners and heat pumps sold around the world use a refrigerant called R-22. Emissions of R-22 are considered by some experts to be a significant factor in depleting the ozone layer that protects animals and people from harmful rays from the sun. Families now have the choice to ask for an air-conditioner or heat pump that uses a more efficient and environmentally friendlier refrigerant called 410A or R-410 when buying a new system for their home.What is a reverse cycle air conditioner ?
A reverse cycle system is one of the best ways to heat and cool your home with electricity. They use as little as one third of the electricity to heat your home to the desired temperature, compared to standard electric heating. A reverse cycle airconditioner, or "heat pump", extracts heat from the outside air and transfers it into your home. This process is reversed in summer to cool your home. They are the most energy efficient electric system to run and will add value to your home.
During the cooler Australian months, why leave your air-conditioning unit to gather dust. By choosing a reverse cycle model, you can take advantage of superb features for a few dollars more..
Imagine that you took an air conditioner and flipped it around so that the hot coils were on the inside and the cold coils were on the outside. Then you would have a heater. It turns out that this heater works extremely well. Rather than burning a fuel, what it is doing is "moving heat."
A heat pump is an air conditioner that contains a valve that lets it switch between "air conditioner" and "heater." When the valve is switched one way, the heat pump acts like an air conditioner, and when it is switched the other way it reverses the flow of Freon and acts like a heater.
Heat pumps can be extremely efficient in their use of energy. But one problem with most heat pumps is that the coils in the outside air collect ice. The heat pump has to melt this ice periodically, so it switches itself back to air conditioner mode to heat up the coils. To avoid pumping cold air into the house in air conditioner mode, the heat pump also lights up burners or electric strip heaters to heat the cold air that the air conditioner is pumping out. Once the ice is melted, the heat pump switches back to heating mode and turns off the burners.
Back to Cooling Mode
Air conditioners employ the same operating principles and basic components as your home refrigerator. An air conditioner cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.
A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils. The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling your home or small business.
The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the air flowing over the condenser's metal tubing and fins.
Air Conditioner Running Costs
| City | Cooling Hrs/Year | Heating Hrs/Year |
|---|---|---|
| Adelaide | 200 | 250 |
| Brisbane | 600 | 100 |
| Canberra | 150 | 500 |
| Darwin | 2000 | nil |
| Hobart | 50 | 450 |
| Melbourne | 100 | 350 |
| Perth | 300 | 150 |
| Sydney | 180 | 200 |
It is important to have a correctly sized air conditioner.
An undersized unit will not provide adequate cooling or heating. Over-sizing can result in frequent on-off cycling, which is not efficient and increases wear and tear. It can also result in cooling with limited humidity reduction.
The air conditioner output, measured in kilowatts(kW), is stated on the label. As an approximate guide for sizing, allow 125 Watts (0.125kW) per square metre of floor area to be cooled in living areas, and 80 Watts (0.08kW) per square metre in bedrooms.
It is advisable to get a full heating and/or cooling load calculation from the air conditioning installer or manufacturer, to determine the appropriate capacity. The amount of use an air conditioner gets, and therefore its annual energy consumption, varies widely around Australia, as the climate is quite different in different locations.
The table above gives typical annual operating hours at rated capacity for air conditioners in different locations. These figures can be used for estimating the annual energy consumption and running costs of air conditioners. Check the typical annual operating hours for your location before estimating the annual running costs.
Average Running Costs
With each degree you lower the thermostat the running costs can be increased by up to 15 percent.- 1750 watt - approx running cost will be between 4.5 to 6.2 cents per hour
- 5000 watt - approx running cost will be between 13.8 to 19.4 cents per hour
- 8800 watt - approx running cost will be between 22.7 to 31.8 cents per hour
