House air conditioning

Depending on the space you have in your home as well as how much control you need, there are a number of different air conditioning types for you:

Domestic split air conditioning system.

The domestic or split-system air conditioner is the usual choice for households. It comprises of indoor units and a fan, and outdoor unit. There will also be pipes containing refrigerant, the chemical formula that passes through the system to help make your environment cooler.

The indoor unit is mounted on a wall in the chosen room, whereas the outdoor unit is stored directly outside on a level surface. The two units connect and their separate components work together to bring cool air to specific rooms of your home. The split system allows you to cool multiple rooms at a time.

Single room air conditioner.

The single room air conditioner is a more simple design for homes that require cooling of one single room. This type also comprises of an indoor and outdoor unit and works in the same way as the split system air conditioner.

Portable air conditioning system.

The portable air conditioning system is a less expensive way to heat up your home and is ideal for anyone with a lack of free space or a smaller room. These units are suitable for the occasional cooling of a room and have no need for a refrigerant.

The home air conditioning system installation process.

Before an engineer can begin, they need to know what they’re working with and whether you have an old system to replace before a new system can be installed. Depending on your engineer, you may be asked to schedule in a survey beforehand to plan where your new home air conditioning system will be fitted. Alternatively, you may need to provide some information over the phone or via email about your requirements and the job that needs to be done.

Your indoor unit.

To install the home air conditioner units of a split system, you must first have an idea of where your units will be based. For the indoor unit, you’ll need at least 15 cm all the way around it in order for the air to flow and circulate effectively. It should be mounted on a wall with plenty of breathing space around the unit.

Your indoor unit should be mounted using the plate provided by your manufacturer. As well as this, your engineer will also create a hole in the wall for your piping to go through. This piping will then be fed through and connected to the outdoor unit. Your engineer will check all the connections within the indoor unit and fix it on the wall mount plate, feeding the piping through the newly created hole.

The process is relatively simple for an engineer. It’s important that you don’t try and install any air conditioning units yourself.

Your outdoor unit.

The outdoor unit should be no more than 4 metres away from the indoor unit, as the two will need to be connected through wiring. It should be placed on a flat surface to prevent flooding or leakage of the system or refrigerant, and can also be placed against a wall for added security. The piping fed through the wall from the indoor unit will be connected securely to the outdoor unit by your engineer.


Each air conditioning system will have its own specific methods and instructions for wiring up the two units, so it’s important your engineer follows these methods correctly.
