 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
