Be Cool installed my new air conditioning system, and I'm quite pleased with the service. From beginning to end, they were professional and helpful. They carefully described the various possibilities and guided me in selecting the finest system for my home. The installation was swift and tidy. The guys arrived on time, worked quickly, and left everything spotless. The new system is working well, and I can already see a change in the temperature in my home. I highly suggest Be Cool for a stress-free air conditioning installation. Excellent service at a reasonable price.

I highly recommend this company. They are very professional and responsive. A bit slow by email but very quick and efficient over the phone. Osama has already come to our office twice and he is really kind and helpful, he answered all my questions and explained to me patiently everything I asked about our A/C.

More expensive than the firm we previously used but I suspect also better work and more honest. Told me one of our units could not be serviced without accessing a hatch over stairs (never saw the previous guy go up there so have to conclude that unit was not serviced ...).

Used Be Cool to service our aircon on the roof of our loft. They coped well with the access challenges, using a long ladder. Pleasant and very conscious of using shoe covers etc.
