Frequently Asked Questions
Looking to buy an Air conditioning system? Not sure what to buy? No worries, below are some questions that you might have thought about. If a question is not listed below, just give us call or send us a message and we will gladly assist you.
Air conditioners come in three forms: portable units, wall split units and ceiling cassette style units.
They each suit different needs and situations but ultimately deliver the same results.
- Portable Units: These are perfect for the home or any environment where versatility is key. They can easily be moved from room to room and between floors. Powerful enough to cool all room sizes without the stress of professional installation. Simply plug it in, vent and feel the benefits.
- Wall Split Units: These units require professional installation but do free up floor space. They are quieter than portable units and are mounted on walls with an external unit that removes the heat and any condensation from the room. As well as cooling, these units are also able to heat rooms more efficiently than central heating.
- Ceiling Cassette Units: Similar to wall split units, these require professional installation but instead of being mounted on your wall they are fitted into your ceiling. Similarly to wall split air conditioners, a ceiling cassette unit has an external unit to remove the heat and can also be used to heat rooms more efficiently than central heating.
Standard Air Conditioner: A normal (non-inverter) or constant speed air conditioner has a compressor running at a fixed speed on 220 VAC. It is controlled by a temperature controller switching the unit on and off. A non-inverter unit, although significantly cheaper to buy, does consume about 1.4 times more electricity. This unit will be effective when running at maximum setting for long periods.
Inverter Air Conditioner: An inverter type air conditioner operates with 220 VAC that is converted to VDC to be able to run the DC compressor at variable-speeds to match a desired load/temperature. This results in a much more economical operation that is more energy-efficient. This unit will be more expensive to buy, but can save you in the long run on operating costs. It also is a good selection when you know your unit demand is not near a 100 % load for the majority of the time. This is where you will get a substantial saving on electricity usage.
It all depends on the size of the room as well as how effective you would like it to be. You are welcome to visit our Request a Quote page and enter the room’s size so that we can assist you with the best option.
Not all air conditioners will work effectively in every room, so it is important to find the right one to match the size of your room. It is also important to think about what the room is used for and how many devices or appliances there are that create extra heat. Also bear in mind that rooms such as a loft room would require more powerful air conditioning than a room of the same size with small windows.
First multiply the length of your room by the width, then review the recommendation below.
15 to 18 m² = 9 000 BTU
20 to 25 m² = 12 000 BTU
30 to 35 m² = 18 000 BTU
40 to 45 m² = 24 000 BTU
55 to 60 m² = 30 000 BTU
The amount of power an air conditioner has is given in BTU, or British Thermal Unit rating. This rating gives you an idea of how much cooling the machine is capable of.
A BTU is the amount of heat needed to raise the temperature of one pound of water by 1°F. When it comes to air conditioning, this measurement means the higher the BTU rating, the bigger the room it can cool. This also means that the higher the BTU, the more it will cost to run.
Depending on what aircon system you have, it should be serviced at least once a year, with periodic inspections up to four times per year. Based on your aircons size, age and usage, a service provider such as EZAIR, will be able to tailor a maintenance and service plan that will meet your requirements and also keep your system running reliably.
If your aircon needs recharging of refrigerant on a regular basis, it is most likely leaking and needs to be repaired. A leaking refrigerant will not only cause your aircon to lose cooling capacity and use more energy, it is also not good for the environment. One of the worst culprits in the depletion of the ozone layer is refrigerant gases being released.
When it comes to the humidity of your building, levels that are too low or high are one of the leading causes of poor indoor air quality, this can also result in the spread of airborne illnesses, mold growth and even computer breakdowns.
When your air-conditioning system is properly designed and controlled, it should keep the air in your building at around 40 and 60% relative humidity. While there are many different methods that have been used to help you aircon remove humidity from the air, one of the most efficient methods involve using the heat that is generated by the aircon itself to cause the unit to run long enough to get rid of more moisture from the air.
Out of experience the best place to install your air conditioner in your bedroom is behind your bed to the left or right of the bed. Installing the air conditioner in the centre could cause uncomfortable drafts. Alternatively you could install the air conditioner on the left or right wall at the foot of the bed.
