Split system air conditioning

Can split system air conditioning serve a larger room?

Matt Mouritz · Director

When they choose Toshiba air conditioning, Perth residents can opt for a split system to heat and cool their homes. One concern many new air conditioning system owners worry about is how effective a system will be when serving a larger room or open plan space. If the system is not correctly sized, the performance will suffer, and your investment will be wasted. Expert advice should be sought prior to making a purchase to ensure that the system isn’t too large or too small. Let’s take a closer look at this process to better understand how it works.

Sizing the space:

The size of your split system air conditioner is loosely based upon the floor area of the space where it will be used. We say loosely because this can only be seen as a very rough guide. More work is required to determine the size of the air conditioning system required than most people would imagine.

A rough room size and air conditioning output guide:

This is a brief size guide for a split system air conditioner.

20 m² – 2.8 kW
30 m² – 4.2 kW
40 m² – 5.6 kW
50 m² – 7.0 kW
60 m² – 8.4 kW

Further considerations for sizing the air conditioning system:

When you work with a professional air conditioning installer, you will be exploring four other factors that will determine the final size of the system.

  1. Ceiling Height: The unit needs to heat and cool all the air in the entire space up to the height of the ceilings. If you have especially high or low ceilings, this needs to be factored into the calculations. This will ensure that you will get the best performance out of your system.
  2. Insulation Levels: A well insulated property will ensure that your levels of heating and cooling will be retained easily. Any split system air conditioning unit will work very effectively with more insulation in the walls and ceiling spaces. The decision between choosing a larger or smaller size of air conditioning system for your space may well come down to how well insulated the room is.
  3. Windows: The number and size of the windows in a room can also be a major factor in your choice. A room with large windows that gets sunshine most of the day will have a major effect on how the room is cooled in summer or heated in winter.
  4. Local Climate: The local climate where your home is located may make heating or cooling more difficult. If you’re in any doubt ask advice from a local professional air conditioning installer and they will understand your local conditions. This will ensure that you get sufficient kW of output for heating and cooling power that is even and consistent.

Ducted reverse cycle

Ducted reverse cycle air conditioning heats and cools your whole home from one system, so you don’t need separate heating and cooling. Zone control sends air only to the rooms you’re using. We work out how many zones you need from the size and layout of your home and how you use it.

Ducted evaporative

A ducted evaporative system from Mouritz cools your home with fresh outside air, and its main advantage is low running costs. It’s cooling only, and works best with a few windows or doors open so the cooled air can flow through the house.

Split systems

A split system heats and cools a room or area, so it suits homes that don’t need whole-home air conditioning. Each one has an outdoor unit and an indoor wall-mounted unit. Split systems work for one room or several, and keep purchase, installation and running costs low.

Solar

A solar power system from Mouritz gives you more control over your energy use and helps reduce your power bills. We design and install panels around your home and energy needs, and battery storage lets you use stored power when you need it. Buying air conditioning too? We offer extra discounts when you buy both together.

Ducted gas heating

Ducted gas heating from Mouritz warms your whole home through ducts and vents, with zoning so you only heat the rooms you need, which can help reduce your energy bills. Installation can be more involved than other heating systems, but you get even, efficient warmth throughout the house.
