Air Conditioning Faq

How does an Air Conditioner work?
Air conditioning systems work by moving heat from inside your premises to the outside. In a central ducted air conditioning system air is drawn into the ductwork system through the return air system. Installed in the return air ductwork is an evaporator coil. This coil is connected to the condenser, the unit that is outside your home, by copper tubing. The refrigerant is then pumped from the condenser to the evaporator coil. As the refrigerant passes through the inside of the evaporator coil, warm air from inside your home passes over the outside of the coil. Because the refrigerant is cooler than the warm air, the refrigerant absorbs heat from the air. The refrigerant is then sent outside to the condenser unit. When the warmed refrigerant is in the condenser unit it is compressed by the compressor; the compression of the refrigerant causes it to boil. As the refrigerant boils it gives off the heat it picked up from inside your home. The refrigerant is then passed through the coil in the condenser unit where it gets cooled again and is ready to go back inside to pick up more heat from your home. As this whole process is going on, the temperature and relative humidity in your premises are both lowered. The relative humidity level drops because cooler air cannot hold as much moisture. As the air cools, it gives up some moisture and it gets collected in the base of the evaporator coil and is then drained away.

How much does it cost?
The purchase price of Air-conditioning units are now more affordable than ever to the general public – a single system can now be purchased for as little as $700.00 for a Brand Name System with full 5 year parts and labour warranty.


How long does it take to install?
In most circumstances, a single or twin split application can be installed in a single day, with minimum disruption.


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 has two primary functions – heating and cooling. Most modern units employ auto change over technology; you set the temperature and the unit will cool or heat as required automatically. The Unit will simultaneously dehumidify and purify the air effectively creating a cleaner and more comfortable environment.

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

How do I know what size air conditioner to get?
To approximate the required capacity of your air conditioner one can apply the figure of 130 watts per square metre of floor area in Australia. This is predominantly used in single rooms for split system type units. For ducted units the 130 watts/metre squared system can also be applied, but only for the maximum area to be zoned on at any one time. This usually amounts to approximately two thirds or 66 % of the total area. This sizing is also based on user preference and area use, if the whole house is often occupied the area to be zoned on becomes 100 %. Please note that any extra heat sources such as large windows, direct sunlight, high occupancy, door openings and high ceilings etc. will need to be factored into the total capacity calculation. For specific information please contact our office.

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, efficiency, noise, etc. Some manufacturers offer a 5 year warranty on all parts and labour while others offer only 1 year. Some units are un-native 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 more than a big headache for years to come. For your protection, make sure you use a specialised, qualified and certified air conditioning contractor.

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 problems when dirty are cleaned to keep the system running smoothly and efficiently. A maintenance service also includes a mechanical and electrical 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.

How often should I have my equipment serviced?
Heating and Air Conditioning equipment should be serviced at least once a year. The best scenario is to have the heating system checked in the autumn and the air conditioning checked in the Spring. If your air conditioning system is a reverse cycle type, we recommend an annual maintenance during the autumn or winter months.
Why should I have my equipment serviced?
Annual servicing includes cleaning the system, checking for any problems or potential problems and adjusting for Peak efficiency. The benefits include:
* Increased dependability.
* Find potential problems and fix them quickly.
* Provide maximum efficiency which lowers energy costs.
* Prolongs the life-span of the equipment.
* Maintains safe and healthy operation.
* Can help to protect the environment.
* Drastically reduces the chance of a break-down which often happens at night or on weekends when repair rates are higher.
Many Service Plans also include extra benefits, including:
* Discounts on repairs.
* Discounts on purchases and future replacement.
* Priority Status for Scheduling.
* Increased warranty duration.
What size heating and air conditioning system do I need?
We get asked this question all the time. And having Air Conditioning Warehouse supply your air conditioning system and ensuring it’s correctly sized is extremely important. A system that is too large will cool or heat your house quickly, but you may not feel comfortable. That’s because it will satisfy the thermostat (temperature sensor for the system) before it can adequately remove sufficient moisture from the air during the cooling mode, leaving you feeling sticky and humid. This could even lead to moisture and mould problems. Also the added stress of short-cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and cooling bills.

On the other hand, a system that is too small just cannot get the job done, especially in extreme weather conditions which frequently occur in our climate on the Gold Coast. The air conditioner will run constantly in the summer and the heating or reverse cycle will do the same in winter.
But a correctly sized system isn’t just based on the size of the structure. Many factors go into determining the size of the system. Some of these include: the type of house and walls, type and size of windows, insulation, basement and roof-space conditions, house orientation, lighting loads, cooking equipment and other factors. A Salesman must visit the house and take detailed measurements and notes while conducting the survey.
