The average air conditioning installation cost for a split air system is between £1,750 and £7,500. Alternatively, the average air conditioning installation cost for a ducted system is £3,000.

That said, it can be tricky to give an accurate figure for how much air conditioning installation costs as there are a number of variables that impact the price. These include:

• Size of AC - Bigger units are generally more expensive than smaller units

• Size of room - If your room is large, you’ll need a bigger, more costly unit

• Type of AC - Portable air conditioners will be cheaper than split air or ducted systems

• Number of units - The more units you need, the higher your air conditioning installation cost will be

• Extra features - You can expect to pay more for extra features like a timer, sleep mode or remote control

• Location - The price of labour will vary depending on where you live. London is typically the most expensive area of the UK

This really depends on the type of air conditioner you choose. Portable air conditioners are a lot easier to install than split or ducted air conditioners. When it comes to taking on AC installation yourself, we wouldn’t advise attempting to install a split or ducted system unless you have experience and training.

Remember, mistakes can lead to damage to your home and the air conditioner. What's more, you could injure yourself or your family through poor workmanship. As such, we’d recommend hiring a trained expert who offers aircon installation in Lerwick for this job.

Installing a split or ducted air conditioner is difficult, time consuming and not recommended for inexperienced DIYers. However, if you’re considering installing a portable air conditioner yourself, this is a much more realistic project.

To help guide you, we’ve summarised the process of installing a portable air conditioner below:

1. Thoroughly read through your new AC unit installation instructions

2. Find a position that’s close to a window and a power outlet

3. Start by installing the window adapter kit that came with your new air conditioner

4. Attach the exhaust hose to your air conditioner

5. Attach the other end of the hose to your window adapter

6. Secure the exhaust hose to your window adapter (you can use tape if necessary)

7. Close your window so it lines up with your adapter

8. Plug the power cable into your power outlet and enjoy

Depending on the type of AC unit, you’ll need to wait a little while before turning it on. Most ACs will need around 30 minutes for the freon to settle before they can be safely switched on. Other systems may need up to 24 hours before they can be used.

The waiting time should be listed in the manufacturer's instructions that came with your new unit. A professional will be able to advise you.
