 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

 Trustindex verifies that the original source of the review is Google. Based on local recommendations Allan and his wonderful team provided 4 x aircon units into our residential property absolutely perfectly. Not only are they incredibly professional but they are so friendly (the reviews on their customer service are 100% accurate), leave the house spotless everyday and are exceptionally quick!  Our aircon was installed within 4 days and just in time for this heatwave. The units are sleek and quiet & our fears about. Huge external unit have been put to rest as they are  boxed in and when all units are running it is also very quiet. We have already recommended Arcas to others.

Frequently Asked Questions About Air Conditioning

How much does it cost for Air Conditioning Installation London home?

The cost of air conditioning installation depends on several factors, including the size of the room, type of system selected, pipework requirements and installation complexity. Our single-room installations start from £2,400, with every quotation tailored to your property and requirements.

Do I need planning permission for Air Conditioning Installation in my property?

In many cases, air conditioning installations do not require planning permission. However, requirements can vary depending on factors such as your property’s location, whether it is a listed building, conservation area restrictions, and the position of the outdoor unit. Our team can advise you on the best installation approach for your property.

How often should my air conditioner be professionally serviced?

We recommend having your air conditioning system professionally serviced at least once a year to maintain efficiency, improve performance and help extend the lifespan of your equipment. Regular servicing also helps keep filters clean, maintain good air quality and identify potential issues before they become costly repairs.

Can Air Conditioning units also heat my home?

Yes. Modern split air conditioning systems can provide both cooling and heating, making them an efficient solution for year-round comfort. Many systems use heat pump technology to provide reliable warmth during colder months while helping maintain a comfortable temperature throughout your home.

Are your air conditioning engineers qualified and insured?

Yes. As a company, Arcas Air Conditioning is F-Gas registered and REFCOM certified, ensuring our work is carried out safely and professionally. Our engineers have the experience and qualifications required to install, service and maintain air conditioning systems to a high standard, giving our customers complete peace of mind.

Do installations qualify for 0% VAT?

Most residential air conditioning installations qualify for 0% VAT, since HMRC treats fixed, reversible air conditioning systems as air source heat pumps. This doesn’t apply to commercial installations. This relief runs until 31 March 2027, after which it reverts to 5% VAT. We’ll confirm your installation’s VAT treatment as part of your quote.
