How Do Standard Air-Conditioners Differ from Inverter Air-Conditioner?
A standard air conditioner has a fixed speed compressor motor on 220 VAC. The compressor runs at full speed until the desired temperature is reached, then switches off. It starts again when the room temperature increases. Because the unit switches on and off frequently to restore temperatures to the desired level, it constantly runs at high power and as a result, is less energy-efficient than an inverter unit.
An inverter air-conditioner has a variable speed compressor motor that adjusts to control its cooling and heating capacity as required. This makes it more economical and energy-efficient than its non-inverter counterparts. While these units cost a little more to buy, their low operating costs save you money and electricity usage in the long run.
Which Kind of Air-Conditioner Should I Use At Home?
Although there are many available on the market, the most popular and recommended are:
- Mid-wall split units
- Ducted centralised systems
- Cassette split units
- VRV/Multi-V/DVM Multi-Zone systems
What Are the 3 Basic Types of Air-Conditioners?
Room air conditioners- These are designed and sized to cool single rooms, and are installed in windows or through walls. They rely on a fan to blow air throughout the room. Depending on its capacity and the amount of power needed, they can be plugged into standard power outlets or directly into a buildings electrical board. These are ideal for cooling only a few areas of a home or office.
Central air conditioners– This is a system in which air is cooled or heated at a central location and distributed to several rooms by one or more fans and ducts. If you require air-conditioned air in multiple rooms, this might be a better (and sometimes more cost-effective) option.
Multi-systems– A multi-system can have multiple indoor units all connected to one outdoor unit through a network of piping and branches. They can provide efficient temperature controlling in multiple rooms with no need for ductwork. Power consumption can be reduced through the different operation options available on the controls.
How Do I Preserve the Lifespan of My AC Unit?
With good care and maintenance, your unit can last several years. This includes:
- Cleaning the filter every three months, especially during Summer and Spring when dust and pollen are most prevalent
- Ensuring that there are no obstructions in the condensate pipe so that it drains freely
- Keeping plants at least 1m away to ensure adequate air circulation around the condensing unit
- Cleaning air outlets regularly
- Having your air-con serviced by an accredited installer
- Following the maintenance recommendations in your warranty
What Are Some of the Benefits of Air-Conditioning?
- Creating comfortable home and office environments through temperature control
- The ability to heat, cool and dehumidify a room
- Eliminating dust, pollen and germs in the air (dependent on the type of unit installed)
- Reducing possibility of asthma attacks, dehydration and heatstroke
- Better sleep
Can Air Conditioners Make You Sick?
A well-maintained AC can contribute to a healthier environment, whereas a poorly maintained one can make you ill. By controlling humidity, the growth of dust mites and mould is reduced, which is beneficial to people with allergies. Additionally, because all air-conditioners are fitted with a filter, they can eliminate bacteria, virus, smoke, odours and even microbes. This is dependent on the type of AC unit installed.
What Is HVAC?
HVAC is an acronym for Heating, Ventilation and Air Conditioning used to describe the complete system which includes air-conditioning, extraction and fresh air supply.
Why Is Regular Maintenance of My AC System Important?
If not maintained routinely, an AC unit can stop functioning effectively and potentially stop working completely. It is also important to maintain one’s air-conditioner on an annual basis to ensure that the warranty stays intact.
How Long Does It Take to Switch from Heating to Cooling, and Vice Versa?
Although this is dependent on the make and model, the average time lapse is approximately 5 minutes.
How Important Are Quality and Backup?
There are over 50 different makes of air-conditioners available in Australia. However, not all are good buys, particularly if they offer poor after-sales support and if sourcing parts for them is difficult. Fourways works with only the best brands on the market, with nationwide spares and service facilities, so that you can buy them with complete confidence knowing you will always have total after-sales support.
