Frequently asked questions

What is an inverter?

An inverter is a term that originates from the “inversion” of a sine wave that is generated from an “Alternating Current” (AC) power generator. Primarily the main source of power that is fed to all homes, this power oscillates into a wave like current. An inverter inverts the wave form and smooths it out to produce a “Direct Current” DC which can then be used to variably control the motor in your compressor. Confused?

Simply put, it can vary the speed of the compressor, saving energy when you only need a trickle. For example, at night when you are sleeping.

When wouldn’t I need an inverter?

It’s rare that an inverter is not the cost effective solution, but in some circumstances an AC compressor might suffice if the air conditioner is going to run at near maximum capacity during the daytime working hours and be switched off at night.

What temperature should I set my air conditioner?

This is the most misunderstood aspect of air conditioners in the home. An air conditioner will create a difference in temperatures and won’t get any colder if the ambient temperatures remain high. At night as the ambient temperatures drop the air conditioner may reach the ideal and the thermostat will cut in and allow the compressor to have a break.

24c is an ideal temperature setting and where days are hotter, a higher setting may produce better results. An air conditioner than runs non stop may be subject to freezing and this in turn will reduce cooling and power efficiency.

What is the best place to position an air conditioner?

An air conditioner is a recirculating system, it takes air within the room and circulates it, it does not intake fresh air and create a flowing current. With this in mind, the best position is that near the warmest part of a room, and it should be installed as HIGH as possible where cooling is the priority. Take into consideration that windows and doors have supportive beams and installation can be difficult. Refrigerating air conditioners also create condensation and the drains are gravity fed hence fall is required. Ideally you want the air conditioner to intake as much of the warm air in the room immediately and circulate the static volume of air in the room evenly.

What positions should be avoided?

Avoid installing air conditioners above your sleeping area. Whilst it may be refreshing to think that on a hot night over 30c a cool breeze is what you need, consider that once the room temperature drops to 25c, (as mentioned earlier) the temperature differential may produce a chilling blizzard like wind of 15c. Additionally, the colder air produced by the air conditioner may produce condensation on your favourite glass framed photos and art, consider moving these precious items when installing an air conditioner directly above them.

Is a separate power circuit required for an Air conditioner?

For the most part, air conditioners draw a considerable load on a circuit’s available current and as most domestic power circuits are rated at 15-16amps/240V. A large room will most likely require it’s own circuit and there is little argument to this need when the issue of safety is in question. Whilst many older installations may be plugged into a wall outlet, C.E.A maintains high quality electrical standards and terminates its units to existing or new circuits, hiding wiring and producing high quality, aesthetically pleasing installations.

Whilst C.E.A is installing circuits, the added bonus is that it also ensures your switchboard is in good working order for a modern lifestyle ensuring your family, home and appliances are safe and correctly configured for the demands your place on power and energy consumption.

How important is condensate drainage?

This is the most overlooked aspect of refrigerated air conditioning, specially along the the coastal areas of Queensland and Northern NSW. The humidity levels in Brisbane are quite high and a surprising amount of condensation is formed, so much so that a considerable amount of time is spent on the drainage of an air conditioner in comparison the the gas fitting. The drains can not be fed into a water tank as the water is a product of your sweat as well as the ambient humidity. It should not be recycled and should be drained into the storm water systems where possible.

Another key installation feature of C.E.A is the insulation of the drains in the internal wall cavities of your home. The condensed water itself is cold and creates condensation on the PVC pipes, if they are not correctly insulated the moisture will rot your walls and internal framework. It’s yet another quality assurance C.E.A ensures its clients.
