What our Customers Saying

“I live in an early Georgian terrace in Spitalfields and during the heatwave of 2018 the top floor, where I work and sleep, was uninhabitable with temperatures regularly topping 35C. Things got so bad I had to set up a mattress in the basement!

The house is Grade 2 listed and has very little outdoor space, so it was rapidly apparent that a conventional outdoor condenser just wasn’t an option.

I contacted several companies for advice about alternative ways of cooling the space and ACS were by far the most impressive. They offered a clear-sighted appraisal of the only solution to the problem, a water-cooled system, they showed flexibility with regard to problems of water pressure and electricity supply, and, on top of that, their quote was the most competitive. The installation was quick and tidy. It’s a very non-obtrusive system visually – ideal for a listed Georgian interior. The condenser is situated in the attic and cool air comes through slimline grilles in the ceiling. Back-up service is good as well. When the system closed down after a fall in water pressure, ACS sent out an engineer who showed me how to access the reset button

The system is fantastic, it easily cools very hot attic rooms down to a tolerable 20C. It really has revolutionised my life. I no longer dread the summer heat!

Completely recommended.” Read more

Juliet – Water Cooled Air Conditioning for Listed Buildings – London Spitafields 

 

“I contacted ACS and initially hesitated because they quoted a better price for a higher quality product than the competition. I had an initial survey done by ACS and then a follow up review to make sure what was quoted was fully implementable. They were very flexible on scheduling the installation and worked around my hectic timetable. Their work was efficient, clean and very tidy. I had a few complications in my flat, which Mark worked around and resolved. The team never complained about my scheduling and even worked a very long day to complete the works. My family is overjoyed at having the a/c, so I’m satisfied.” Read more

Ziad – Installation of a Water Cooled Internal Condenser (air conditioning with no outdoor unit) – Chelsea, London

 

 

“Due to restrictions which prevented an external condenser, I invited ACS to come up with a solution. They were extremely professional and helpful and quickly understood exactly what was required and they also recognised the very tight schedule I was having to work within. They pulled out all the stops to ensure the project was completed on time. We now have a wonderfully cool bedroom – even when the temperature outside is in the high twenties. I cannot recommend them enough – fair value and friendly people.” Read More

Nick –  Water Cooled Air Conditioning in Flat – Charles Street, Mayfair W1

‘I can fully recommend ACS who did a wonderful job in installing air-conditioning into our apartment, at a competitive price. ACS performed a tidy and professional job and the end result has literally transformed our apartment by the introduction of an internal system which doesn’t require external access. Perfect for apartments which suffer from hot temperature with restrictions on external vents. Antony, Highbury Stadium Square.’ Read more

Antony – Installation of Air Conditioning with No Outside Unit – Highbury Stadium Square

“This was a replacement installation made more complex by the way the developer had boxed in the units. The decorator selected by ACS (a regular) did an excellent job to widen the gaps with a minimum of mess and disruption and subsequent clearing up! Then the ACS installers moved in and did a fabulous job. You rarely encounter such a thorough, knowledgeable and conscientious worker as the lead installer and it’s gratifying to see the way he is installing the same qualities in his younger trainee assistant. Once again everything cleared up as they went along. Finally, after commissioning, the job was handed back to the decorator who closed up and repainted extremely well. ACS are thoroughly recommended for your AC installation and subsequent servicing.” Read more

Euan – Air Conditioning Installation in Beckenham, Kent

 

“I have no hesitation in recommending ACS highly enough. Not only was their work of an excellent quality and their quoted price competitive, they also showed a great spirit of flexibility especially when due to unforeseen circumstances I had to cancel at fairly short notices two previous installation dates.” Read more

​Raouf – Installation of  Water Cooled Air Conditioning – Altura Tower, Battersea, London

“The guys at ACS recently installed several new air conditioning systems at our flagship showroom. They were efficient and curteous and the end result was a very comfortable climate. Would very highly recommend!”

Reflections Croydon

“As an IT Support and Hosted Desktop company we require efficient and reliable air conditioning systems. After dealing with many unreliable companies its good to know we can rely on All Comfort Solutions to deliver quality products and great customer service.”

Paul Sturges, Managing Director – Horizon Computer Solutions Ltd

 

 

“Over four years ago I approached ACS to discuss installing air conditioning in my master bedroom and lounge. I was impressed by the professionalism of all the personnel I met and the Daiken units were installed in the course of a morning. Since the installation I use the a/c units a lot and have had no problems. I also opted for a six monthly service contract and again I cannot speak too highly of the service provided throughout this period. With this context and the high temperatures we experienced this summer I asked ACS to quote for and install another unit in my kitchen/diner as the heat was making cooking very unpleasant. Given the company was stretched with similar requests I was very pleased with the speed with which they supplied the kit and it was installed within 3 weeks of my receiving their quote. ACS have and continue to give excellent service and I now have three rooms where I can cool to the temperature and environment I prefer. I would recommend them every time.” Read More

Richard – Residential Air Conditioning, New Malden, Surrey

“ACS are always very helpful, they will send an engineer out quickly to fix any faults. The engineers that visit are very knowledgeable and will only complete work that is necessary. Our server room air conditioning unit was failing in the summer and would not have lasted over the very hot weekend ahead. They quickly sourced us a new one and installed it so it was up and running by 6pm on the Friday afternoon, saving us from disaster. Fantastic service.” Read more
