Absolutely amazing service provided by the team. The professionalism and good nature of the team made installation seamless and with minimal disruption. The advice that I was provided prior to installation and on the day of installation was brilliant. The job is very neat and tidy which was a given as the team are very passionate in the service they provide. The machine itself is of high quality and does the job required with various functionality. I highly reccomend CapCool as you will not be disappointed. Thank you for your service

Capcool provided us with very professional service from the very beginning to the end. Erica has been very responsive and accomodating from the first contact regarding bookings and quotes. Fahan, Adnan, Imran and Ibreham worked for us for four days to install the three multi-units for six rooms of different sizes. They are all very dedicated and they work very hard to find solutions to minimize the potential changes/damages to the existing interior. Many thanks to everyone!

What an amazing Company!
Erica promptly arranged the initial site visit with Farhan on the same day!
Farhan is very knowledgeable, friendly and passionate about air conditioning and was happy to explain any queries and provided guidance according to our needs. The quote received was competitive and very reasonable. Subsequent changes to our requests were promptly explained whilst providing neatest solution rather than making their installers life easy. Our team of installer were: Adnan, Imran and assistant Ibrahim absolutely brilliant team. Highly impressed with the neat trunking installed

We were so impressed with the level of professionalism, knowledge and expertise - from our initial contact, the plan for the work and detailed quote, all the way through to the work carried out and aftercare. Farhan, Adnan and their team were exceptionally courteous, tidy and careful when undertaking the work for our new ac system in our home. The work was done within the expected time frame and exact cost. We can thoroughly recommend CapCool without hesitation and are beyond happy with the end result. Thank you Farhan and your team!
