Air Conditioning Systems We Install

Single-Room Split Systems

A split system connects one indoor unit to one outdoor unit. It is a practical choice for bedrooms, loft conversions, living rooms, home offices and smaller commercial spaces.

Multi-split Systems

A multi-split system connects several indoor units to one outdoor unit. It is ideal for homes, apartments and businesses where several rooms require independent heating and cooling but exterior space is limited.

Ducted Systems

A ducted system distributes cooling through discreet ceiling or wall vents connected to a concealed indoor unit. Ideal for homes, apartments and businesses where multiple rooms require comfortable temperature control while maintaining minimal interior appearance.

Ceiling & Suspended Systems

Ceiling cassette and suspended systems provide efficient heating and cooling for larger commercial spaces, including offices, shops and restaurants where wall-mounted units may not be suitable.

 Trustindex verifies that the original source of the review is Google. Arcas Air Conditioning was highly recommended to me by a neighbour and I can understand why. The team did a fantastic job of installing air conditioning in a large kitchen/diner and were very knowledgeable about the best type of unit. It was a neat, well executed job and their carpentry surrounding the outside unit was excellent. They were also very tidy. I have no hesitation in recommending this firm. Their quality (and speed) of communication was also excellent.

 Trustindex verifies that the original source of the review is Google. Excellent service from start to finish. Allan came out very quickly after our initial enquiry and provided a quote almost immediately. Once we’d decided to go ahead, the installation was booked in and completed really quickly.

The installation team were fantastic – friendly, professional and incredibly tidy. They left the rooms exactly as they found them, and you genuinely wouldn’t have known they’d been there.

A great experience all round with a lovely team. I’d highly recommend them to anyone considering air conditioning.

 Trustindex verifies that the original source of the review is Google. Alan did a great job from start to finish. From the first visit he clearly communicated his recommendation, the cost and timing. His team did a great job cleaning up and even built a wood cover for the unit outside. I would definitely use Alan again and highly recommend.

 Trustindex verifies that the original source of the review is Google. Allan and his team installed air conditioning in our loft bedroom this week (June 2026). They did a great job. Very professional. Communications were faultless. Always knew what was happening and who was doing what. Responsive too. Resolving issues during the installation process to my satisfaction. Good VFM too. Highly recommended. Roger W5

FAQs for Air Conditioning Installations

How much does air conditioning installation cost in Richmond?

Standard single-room installations start from £2,400. The final cost depends on the system, room size, pipework requirements, outdoor unit location and installation complexity.

Can you install air conditioning in a flat?

Yes, subject to suitable equipment positions and any necessary permissions. Riverside and town centre flats often require freeholder approval given how much of Richmond sits within conservation areas, which we check before any work is booked in.

Can one outdoor unit operate several indoor units?

Yes. A multi-split system connects several independently controlled indoor units to one outdoor unit. This can be helpful where exterior space is limited.

Can air conditioning heat my home?

Yes. Modern air conditioning systems provide both heating and cooling, allowing them to be used throughout the year.

Do I need planning permission?

Many installations do not require planning permission, but large parts of Richmond — including the town centre, Richmond Green and the riverside — fall within conservation areas with additional rules on outdoor unit placement. Properties further out towards East Sheen are typically less restricted, but we check every property individually.

Do you provide the estimate before the site survey?

Where possible, yes. We initially review your photographs, room dimensions and installation details. If you are happy with the estimate, we arrange a site survey and prepare the final quotation.

How long does installation take?

A standard single-room installation can often be completed within one day. Multi-room, ducted and more complex projects may take longer. We confirm the expected timeframe before work begins.
