Aircon Size Calculator

Calculate the cooling or heating capacity required for your area with ease. Our calculator will guide you in choosing the right option for your home or office. This is a guide only, so please call us if you need any assistance.

What size aircon do I need to buy?

The aircon unit you require will depend on the size of the room you want to cool or heat. You will need about 600 BTUs per square meter. Multiply the length of the room by the width of the room and then multiply that number by 600. The units on our website also display the square meter space it can cover.

What is your room size and which appliances are in it?

Your air conditioner will work well if you choose the right one based on the size of your room. You might also want to consider what the room is used for, and which appliances are used in that room – as they can create added heat. A bigger and more powerful aircon will be needed for a loft type room compared to a small room with windows. Simply refer to our calculator to determine the air conditioning power you will require.

If you are still unsure or have any other questions, please feel free to contact us.

How much power will I need?

BTU is the measurement for air conditioning power. The unit’s BTU rating will determine how much cooling power the system can deliver. Higher BTU ratings mean that the aircon is capable of cooling a bigger room, but this will also mean that it will use more electricity, increasing the running cost.

What are the types of air conditioners that are available?

There are 3 types to choose from: Ceiling cassette style units, wall split units as well as portable air conditioners. Each one of them deliver the same results and serve a similar purpose, but the unit you require will depend on your needs.

Wall Split Units: These units have to be installed by a professional. It’s the perfect solution when you need floor space freed up. Wall split units run quieter than portable aircons and they can also heat rooms much better than central heating options. Wall split units are mounted on your wall and they have an external unit on the outside that removes condensation and heat from the room.

Ceiling Cassette Units: Just like wall split units, ceiling cassette aircons should be installed by a professional. The main difference between the two is that these units are mounted on your ceiling instead of your wall. They also have an external unit on the outside that removes condensation and heat from the room.

Portable Units: These products offer great flexibility. Portable air conditioners can be moved around as you need them. They can be moved between rooms and floors and you can even take it with on holiday. It’s easy to use, needs no installation and is powerful enough cool any room.

What is the difference between inverter and non-inverter Aircons?

Inverter aircons are specifically designed to be more accurate when it comes to the temperature you require. Non-inverter aircon compressors run at a fixed speed, providing a fixed amount of cooling or heating. The compressor starts and stops when required. Inverter aircons on the other hand have controllable compressors that adapts to keep your room at the temperature you require at all times.

Are there specific features I should consider?

Look out for the following features and make your decision based on what works best for you and your situation at home.

Mode Settings: Consider the mode setting of your aircon. They come with many mode settings to cater for your needs. These settings include cooling, dehumidifying, heating and fan settings so you can reduce fan speed while you sleep.

Adjustable Thermostat: This feature is amazing when you need a consistent, comfortable temperature at your home or at work. You are in complete control because you can set the temperature you are most comfortable with and the regulator will remain on that temperature until you choose to change it.

Timer: If you want your aircon to switch off when you go to sleep or if you just want to save on electricity costs – this feature is great. You can set the timer so that the aircon powers on and off as you need it.

Sleep Mode: For a good night’s rest, comfort plays a big role. Sleep mode keeps you cool during the night without making a lot of noise. The temperature also automatically regulates throughout the night which ensures a good night’s rest.


Pool Heat Pump Size Calculator

Calculate the cooling or heating capacity needed for your swimming pool. This is only a guide, so feel free to give us a call if you are unsure or if you have additional questions. 

How do I know what size heat pump to buy?

You need to select the right heat pump to match the size and depth of your swimming pool. Use the calculator to determine the size of the heat pump you will require for your pool. If you are still unsure or if you have any other questions, feel free to contact us.

How much power will be required to heat my pool?

Heat energy is measured in kW. The kW power rating of your pool heat pump will give you an indication of the amount of heat it can generate. If the kW rating is higher, your pool will heat up quicker and a higher kW rating also means that you can heat up a larger pool.

Any specific features I should look out for?

This depends on your expectations. It’s always wise to consider a heat pump with a titanium heat exchanger. Titanium heat exchangers come standard with all our Alliance swimming pool heat pumps. Also be on the lookout for temperature ranges. Our range of heat pumps can heat your pool up to 43 degrees Celsius.

Should I consider a pool blanket?

Pool blankets help to retain the heat by keeping heat from escaping and when your pool is covered, there is less cold air blowing on your pool. Thermal pool blankets could mean that you can get away with a smaller heat pump and it reduces the amount of energy use too. You can add a thermal pool blanket to your order with ease. 

Just how big should I go?

Bigger is always better when it comes to pool heat pumps. Bigger heat pumps mean that your pool can be heated much quicker and that reduces the running time of your heat pump to get your pool to the temperature you desire. You can save on power costs and enjoy your heated pool much quicker.

Does my heat pump have a warranty?

RightAir offers a great warranty on all Alliance swimming pool heat pumps. We offer 12 months warranty on the unit, 12 months on the heat exchanger and 3 years on the compressor.

Will I be able to install my swimming pool heat pump?

You have access to detailed instructions that you will get with your  heat pump package. All you are required to do is connect the unit to your current pool pump. You also need to supply the right amount of power to the unit. If you are confident you can manage the installation, you can download the manual here, but you are also welcome to ask for a professional installation.
