Choice Cooling Ltd | Frequently asked questions

Frequently Asked Questions:

What are the benefits of Air Conditioning?
The benefits of Air Conditioning are to give a comfortable environment at work or at home throughout the seasons, Spring, Summer, Autumn and Winter.

An Air Conditioning unit can have two functions - heating and cooling.With an auto changeover switch on most new units, you set the temperature and the unit will cool or heat as required automatically.

Which manufacturer makes the best air conditioner?
Air conditioning is a matured technology so most of the popular brands work well. Many of them use parts made by the same manufacturers. So, the main considerations are the price, warranty, attractiveness, noise, etc. Some manufacturers offer a 3-5 year warranty on all parts while others offer only 1 year. Some units are unattractive and will not compliment your landscaping.

Whatever you decide, the most important consideration is the contractor you use. You may buy the best system in the world but if it is not properly installed, you will actually be buying nothing but a big headache for years to come. For your protection, make sure you use a specialised contractor.

Where can I use Air Conditioning units?
At Choice Cooling, we sell air conditioning units for use in domestic premises, offices, shops, food processing areas, factories, computer rooms and restaurants.

What is air purification?
An anti-fungus filter is used - this catches allergy-causing mites, smoke particles and odours, making the air in your environment clean and fresh.

Why bother with a yearly Preventative Maintenance Service?
Yearly preventative maintenance is a wise thing to do. Properly maintaining your system will save you money on your energy bills and will help your system perform at peak efficiency. A properly maintained system also lasts longer which is important due to the expense of replacement. During a preventive maintenance, certain parts that can cause trouble when dirty, are cleaned to keep the system running smoothly and efficiently.

A maintenance service also includes inspection of your system so problems can be discovered before serious damage occurs and you find yourself without air conditioning in the middle of summer or winter when you need it the most.

My air conditioning is not working - What can I do?
One of the most common causes of failure is that some one has switched off the power supply. So check that fuses circuit breakers and isolators are all OK and working.

Another common cause is blocked air filters, so check they are clean and are regularly kept clean. It helps to refer to the manufacturers operating instructions as well.

If all else fails and you are still having a problem, contact our service department.

What is COP?
Coefficient of Performance, which is the ratio between the power input and power output. For example a modern heat pump will provide 3kw of heat for 1kw of electrical power input. Therefore the COP is expressed as 3 - 1.

I have been told that air conditioning spreads viruses and bacteria - Does it?

No more than you do or any ventilation system does for airborne viruses and bacteria. Many people are susceptible to dryness sometimes caused when an air conditioning system is badly designed or maintained and the relative humidity is reduced too much. It's a fact that basically coughs and sneezes spread diseases, but some people will blame anything for their ills rather than understand the facts.

What is EER?
Energy efficiency ratio is used to express the relative efficiency of a heating or cooling device by dividing the heat output by the power input. The higher the ratio compared to others, the better the system is.

What is VRV or VRF?
VRV is a system developed and designed by Daikin Industries and means "variable refrigerant volume". Daikin protected the term VRV so other manufacturers use the term VRF "variable refrigerant flow". In principle they both work the same and are extremely efficient, reliable, energy saving ways to heat and cool all types of buildings with minimum installation time or disruption.

The volume or flow rate of refrigerant is accurately matched to the required heating or cooling loads thereby saving energy and providing more accurate control.

In short, they are probably the best systems currently available for mid to large applications.
