air conditioning West London unit in garden

If you’re considering air conditioning for your home or business in Chiswick or the wider West London area, it’s important to understand the different types of systems available. With a range of options designed to suit everything from bedrooms to open-plan offices, there’s a solution to match every need, space, and style.

We install air conditioning systems for both residential and commercial properties, offering everything from discreet ducted systems to compact units for loft rooms.

Modern air conditioning units do far more than just cool a space. Many systems now offer heating functions, acting as an efficient alternative to traditional radiators, perfect for keeping rooms comfortable all year round. In addition, advanced models come with built-in air purification, dehumidifying, and even humidity control features. This means they can help improve indoor air quality, reduce allergens, and maintain a more balanced, breathable environment making them a great choice for both homes and workplaces.

Types of Air Conditioning

Below, we break down the most popular types of air conditioning units and where they’re best used.

1. Wall-Mounted Units

Wall-mounted air conditioning units are a popular choice for homes and small offices. These units are fixed high on a wall and deliver efficient, targeted cooling. They’re quick to install and relatively cost-effective.

We often recommend models like the LG Deluxe Wall Cassette, which is perfect for bedrooms and other domestic spaces. It’s Wi-Fi enabled, allowing you to control the temperature from your phone. The Daikin Wall Cassette is a great option when you want a more design-led solution. Available in a range of colours, it blends easily into most modern interiors. The LG Artcool, with its sleek black finish and 10-year warranty, offers both performance and style.

2. Ceiling Cassettes

Ceiling cassette units are ideal for commercial spaces like shops, offices, and schools, though they can be used in homes too. These units are mounted in a suspended ceiling, so only the grille is visible, allowing air to be distributed evenly in four directions.

Ceiling cassettes are a great choice when wall space is limited, or when you want to keep the air conditioning out of sight. They’re especially useful in open-plan environments where consistent airflow is needed throughout the space.

3. Low-Level Console Units

Low-level consoles are mounted lower on the wall, much like a traditional radiator. They’re a smart option for loft rooms, attic spaces, or anywhere wall space is restricted due to sloped ceilings or awkward layouts.

Many branded units include Wick Control, allowing for more precise temperature and fan speed adjustments. Despite their size, they offer powerful and efficient climate control.

4. Concealed Ducted Systems

Ducted systems are the most discreet solution available. These units are typically hidden in loft spaces, suspended ceilings, or even built into bespoke furniture. Cold air is distributed through ducting, with only small, subtle grilles visible in each room.

This type of system is ideal when aesthetics are important or when you want a consistent temperature across multiple rooms. While they are the most expensive to install, due to the extra labour and materials, they offer a seamless finish and maximum flexibility.

My daughter had blocked plumbing but was away - John came quickly to meet me at her house, sorted the problem quickly and efficiently and was a great communicator - despite fact he was not dealing with the house owner. Highly recommend

Harry came to help fit a new toilet, fix our slow draining sink and remove a radiator. He did a brilliant job and kept us up to date with what he was doing. Would definitely recommend. Thank you!

Reliant visited us again for our Ecotec gas boiler service. Excellent W4 London assistance checking the boiler and flue, and good advice re electrodes and water temp. and water flow. Excellent service as usual. Peter C.

Reliant are an excellent group of plumbers/heating engineers. I've used them a number of times, ranging from installing a new boiler through to gas safe checks and general plumbing and cannot fault them.
They always turn up on time, if not slightly early, and the works are completed tidily and efficiently and for a good price.
Very much recommended.

I have nothing but good things to say about the service I received from the Reliant team. My boiler broke over Christmas and reliant were recommended to me and they didn’t disappoint. Ricky was round quickly to diagnose, and was reluctant to tell me all of the problems there were with my very old boiler. I decided to replace it and again received fab service from Dennis. They responded quickly, have done great work, were clean and tidy despite having to move multiple appliances to reach the boiler, took their time to show me how to use it and even took care around my pet! All of this for an incredibly reasonable price. I will definitely be coming back for any issues I have in the future and would recommend to everyone.

I have used Reliant on a few occassions for various jobs and have found them to be reliable, knowledgeable and have faith they will resolve the issue. I have also recommended them to friends who have been equally delighted with their work. Would have no hesitation in using them again.

Very happy with the service I received from Reliant. Faris was a nice guy and a great engineer, not only did he fix my boiler he also gave me some advice after I had been scammed by a different company who put a lot of pressure on to upsell me a new boiler. He assured me that my boiler was in good condition and did not need to be replaced so he saved me a considerable amount of money. Wouldn’t hesitate to recommend Reliant - friendly, efficient and honest service. 10/10!
