We required a commercial Air Con solution at short notice and debonair delivered. Site survey and quoted on the same day and they went the extra mile to arrange for the installation to take place over the weekend.The engineers were professional, helpful and friendly. They arrived on time, did the installation, explained the functionality and cleaned up the mess before they left. Happy to recommend.
Quick efficient and super friendly, highly recommend
The Best AC Installation Company! I can't say enough good things about our recent AC installation with Debonair. The entire experience was incredibly easy and stress-free. After seeing their positive reviews online, we reached out and they promptly got back to us to set up a video consultation. Idin was fantastic. He walked us through everything, answering all our questions and providing excellent advice on the best unit placements and sizes for our home. The price is very reasonable and no hidden costs at all. The installation itself took three days and was led by a great team including Mostafa and Idin. They were always on time, polite, and very professional. On the final day, they worked incredibly hard until 8 p.m. to make sure everything was completed. They went above and beyond, helping us move our satellite dish so the outside unit can be put at a better place and travel for a longer distance to buy a pump to ensure our bedroom unit had a quiet, high-quality pump. When the job was done, they left the work areas spotless, so we didn't have to do any cleanup. The final result is fantastic-the AC units are quiet and all the pipes are neatly covered and holes are refilled, making for a clean, professional look. We are so grateful for their attention to detail and hard work. Thank you to the whole team! If you're looking for AC installation, look no further than Debonair.
Fantastic service from start to finish. The team were professional, accommodating, and really understood my situation. With a baby at home during the heatwave, I asked if they could bring my installation date forward, and they did without any hassle. We’re absolutely delighted with our new air con and feel well-prepared for the next heatwave! :)
Great service from start to finish, we are out of the usual area so there was a lot of travel involved for the engineers. We had a multi split unit fitted and three air conditioners inside the house. The job was 4 days but I think a lot of that was due to travel time. There was no mess and barely any noise. I expected lots of disruption so that was a pleasant surprise. All the pipe work/wiring is very well hidden externally along the roofline and inside there is no evidence of any works. The survey was online which was quick and convenient. We couldn’t be happier with the service, the engineers were friendly, tidy and polite. Would definitely recommend Debonair they are very professional from start to finish, any enquiries were picked up and dealt with right away which always gives you confidence in a company. Thanks to all the team!
Would thoroughly recommend using these guys. Did a great job and were very polite.

Was so pleased with the service from Debonair. Was able to get an appointment quickly and at a competitive price and am very happy with the results. Have already recommenced Debonair to others.
The owner and this company is the most customer helpful and extremely polite professional and helpful AC company I have come across. Their knowledge on the products and flexibility to honour a next year installation at the same price is mind blowing. Cannot wait to meet the team next year and get this installed
We have three AC units installed by Debonair cooling on 24th of July 2025. The Guys( Mohammad Bakshayesh, Mustafa, Mohammad Seif, and Milad Shirvani and Nile Kabeho,) delivered an excellent job seamlessly . They were efficient, organized , and were willing to address any queries we had during installation and and were innovative in troubleshooting and went extra mile in sorting out electric access to get the AC units going . We would absolutely and definitely recommend Debonair Cooling without hesitation.
Nigel and Milad were superb! Fantastic service! AC works wonders, better than expected. Thanks fellas
