Cost of Air Con Installation

Installing air conditioning in your home or commercial building is often be cheaper than you might realise, but there are a number of factors that are likely to influence the cost. Below are some of the main pricing factors that will impact on the cost of your air conditioner installation:

  •  AC Unit – there are a number of different air conditioning units available, each with differing power levels and features. A commercial unit will cost more than a residential air conditioner, due to the larger cooling power. Similarly, AC units with advanced features, such as a increased air filtering, will cost more than a basic unit.
  • Property Size – the area you need to cool will be important in deciding the power output of your air conditioner. If you have a large property, a smaller air conditioner will most likely lack the power to sufficiently cool your house.
  • Location – as with almost all home improvements, the cost of air con installation is likely to differ in different parts of the UK. Generally, the most expensive prices are found in London and the South of England. Areas that lack local AC professionals will also result in higher installation costs.

Air Conditioning Installation Prices

The average cost of installing an air conditioner ranges from £1,700 to £2,400, based on a single zone unit. This will provide air conditioning to one room in your property. If you have a larger room, or require a higher specification system, prices are likely to increase. 

The price for installing multi-zone ducted air conditioning throughout an average sized home will typically range from £4,000 to £6,000. A multi-zone system will enable you to independently control the temperature in each room, and will provide a superior cool throughout the property.

An air conditioning installation within a conservatory or converted loft will likely cost between £1,600 to £2,500.

Due to the larger size of most office and shopping spaces, a commercial air conditioner installation will generally cost more than a domestic install. For example, supply and install of a commercial air con unit to cool a 10m x 10m space will typically cost between £5,000 to £7,000.

Types of Air Conditioning Units

Before choosing an installer, it is important to understand the type of air con unit you would like. There are a number of different air conditioning units available, each suited to differing roles. Below we will explore the different types in more detail, including the common uses, and help you decide which is the best air conditioner for your needs.

Wall Unit (Split System) Air Conditioners

The most common domestic air conditioner in the UK, split systems are fast to install and are available in a range of different sizes to suit all rooms. As their name suggests, wall mounted AC units are fixed to your wall, and positioned to deliver the best cooling results for your home.

Pros & Cons:

    • Efficient and Quite
    • Wide range of built in features
    • No internal floor space required for installation
    • Part of the unit will need to be installed on your buildings exterior
    • Not as discreet as ducted AV systems

Split system air conditioners are also used in commercial buildings, but in most cases they are a less popular option compared with ducted and ceiling cassette units.

Low Wall Air Conditioners

A low wall air conditioners are ideal for rooms that require the unit to be mounted at a lower height. They are particularly useful in conservatories and loft conversions. The glass walls of a conservatory and angled walls in a loft conversion mean that traditional wall mounted systems aren’t suitable.

Pros & Cons:

    • Works in rooms that can’t have a traditional unit mounted
    • Spread is not as wide, and can be interfered by nearby objects
    • Limited number of designs and styles

Ducted Air Conditioner

Ducted air conditioning systems are commonly used in commercial buildings to deliver cool air across a large area. They are also popular in homes as outlets can be installed in different rooms and bedrooms, allowing occupants to choose their ideal temperature.

Pros and Cons:

    • Sleek and unobtrusive
    • Ideal for larger homes with many rooms
    • Less features (such as oscillating) and reduced control
    • Large unit installed on the buildings exterior

Ceiling Cassette Air Conditioner

Ceiling cassette air conditioning units are more commonly seen in commercial offices and shops, rather than residential buildings. They work in a similar way to wall mounted units, but are instead mounted in to the ceiling and provide multi-directional air flow.

Pros and Cons:

    • Multi directional air flow
    • Large cooling capacity and non-intrusive
    • Needs an accessible roof cavity to hold the body
    • Often not suitable for home installation

Portable Air Conditioner

Portable air conditioners are a great alternative to in-built systems. They are generally cheaper than larger systems, and also require minimal installation. However, they often lack the same power provided by other air conditioner types, making them less suitable for larger properties. Being portable, they can be easily moved from room to room, but you will need to consider the hot air outlet pipe, which should be directed outside.

Pros and Cons:

    • Minimal installation required
    • Cheaper prices
    • Easily portable for moving between rooms and homes
    • Often require more ongoing maintenance
    • Less effective than other air conditioning types

Whilst they don’t provide the same power of cooling as an air conditioner, an evaporative cooler may be sufficient for your cooling needs. Evaporative air coolers don’t need a hot air exhaust outlet, making them suitable for a wide array of applications.

Air Conditioning Service & Repairs

Even if you have your air conditioner serviced on a regular basis, you may need to have problems repaired. An experienced air conditioning service engineer will be able to quickly diagnose and resolve the issue. Below are some of the most common air conditioning problems that will need repairing.

  • Poor Airflow – If you are experiencing reduced airflow from your air conditioning unit, it may be a simple case of adjusting your remote or cleaning/replacing your AC filters. However, in other cases the fan motor may need replacement.
  • Reduced Performance – A great way to ensure your air con is working at optimal level is to have it regularly serviced. If you experience reduced performance, the cause could be anything from motor failures to built up grime. An air conditioning technician will be able to diagnose the problem.
  • Leaking Water – There is nothing you want less than to have water leaking out over your home. The most likely cause of your air conditioner leaking is due to the condensate (water made by the AC unit) pump not working.
  • Stale Odours – The condensed water produced when the air conditioning unit is in use can result in bacteria growing on the internal coils. Regular maintenance will help prevent this from happening to your air conditioner.
  • AC Freezing – If your air conditioning freezes, this could be due to refrigeration not being able to function properly. In many cases, the air conditioner can be cleaned to fix the issue. In other circumstances, parts may need to be replaced to regain normal function.

Single Zone vs Multi Zone

If you are looking to install a new air conditioner in your home, you have probably come across the terms single zone and multi zone. But, what are they and why are they important? Below we explain the difference, so you can pick the right type for your needs.

Single Zone Air Conditioners

As you might have guessed, a single zone air conditioner is a single unit that will cool the room that it has been installed in. This system is best suited to homes that only require a single air conditioner installed in a central room, such as a lounge room or living area.

Multi Zone Air Conditioners

For more control and greater cooling throughout your home, you will need a multi zone air conditioner. These systems deliver cool air to multiple rooms (either through ducts of additional wall mounted units). Each room can be controlled independently, allowing everyone to be comfortable.

Leading Air Conditioner Brands

Your chosen installer will be best placed to provide advice and suggestions, after assessing your property. Some of the leading air conditioner brands in the UK include Daikin, Mitsubishi Electric, Samsung, Carrier, LG, Fujitsu, Sharp, Panasonic and Toshiba.

Frequently Asked Questions

Below are a few questions our visitors regularly ask about air conditioning installations. Our answers below will hopefully help you, but if we have missed anything, please get in touch.

Adding air conditioning to your home is normally regarded as a permitted development. This means that you will generally not require any planning permission to carry out the install. However, there are some restrictions and stricter rules for certain properties, such as houses situated within conservation areas. If you have any doubts, it is a good idea to contact your local council authority or Planning Portal for clarification.

Due to the complicated installation process and electrical work involved, we would recommend leaving this home improvement to the experts. However, this does not apply to portable air conditioners, which only require minimal set up and installation work. Portable air conditioners do not require electrical work, making them much safer for all levels of DIY’er.

Most standard wall mounted air conditioner installations will take no more than around 2-4 hours. There will be minimal disturbance during the install, so you will not need to move out. If you are having a more complex installation, such as ducted throughout your home, the work can take up to a day or two.

For certain types of air conditioning installations, your chosen contractor will need to be qualified in order to carry out the work. Due to the electrics involved, it is also a good idea to ensure that they are competent and experienced in carrying out air conditioner installs.

If your installer is taking away waste (such as an old air conditioner or building waste), they should have a waste carriers licence.

Asking questions is a great way to better understand potential installers. Below are a few questions that you can ask potential installers to gain a better understanding of their experience and services.

  1. How long have you been installing AC?
  2. Do you have any example photos of your previous work?
  3. Can you provide testimonials or references?
  4. Do you have public liability insurance?
  5. How long will the installation take?
  6. Do you supply everything needed for the project?
  7. Are there any additional costs I should be aware of?
  8. Does your pricing include VAT?
  9. Will you take away any rubbish?
  10. Do you provide any discounts of concessions?

Other Considerations

  • Comfortable and cool temperatures in your home or office during the warmer months.
  • Quick installation times.
  • Numerous types to suit all budgets and requirements, including portable systems.
  • Modern and sleek designs available to suit your homes decor.
  • Air conditioners use a lot of energy, which will increase your electricity bill.
  • Most air conditioner types require part of the system to be installed on the buildings exterior.
  • Air conditioning installation prices can be quite costly.

Air conditioning installations normally have one of the best warranty’s in the home improvement industry. Many installers provide a warranty of at least 10 years. A warranty will provide peace of mind that if anything was to go wrong, your air conditioner will be quickly fixed.

As well as ensuring your chosen air conditioning installation professional has the required qualifications to carry out the work, it is important that they also hold valid public liability insurance. This is an insurance that will protect you and your home if something was to go wrong during the building.

You can request a copy of your builders PLI certificate, which they should be able to email or print for you.
