" The Guys. Luke and John installed 2 units for me, they were really friendly and easy to get on with. They were very respectful of our house, making sure they laid dust sheets down to keep the carpets/floors clean while going in and out of the house. They hoovered the dust as they drill to ensure minimal dust spreading. Emailing. Super fast at getting back to me and were always happy to answer any questions and I like to ask lots of questions. The Samsung A/C units. The units that we had installed are really stylish and very clever you can control them from your phone with lots of different modes. I can’t recommend Supreme Heating Cooling enough, no messing around, quick, to the point and trustworthy. 10/10 service will definitely use again in the future. "

Luke Manders

" Called Supreme to ask for a quote for home air conditioning. Luke called us back to make an appointment and arrived on time on the day requested. We had no real idea of what we needed and were very impressed by Luke's knowledge and recommendations of what would be perfect for our property. There was no big oversell , he just took his time upstairs and down and advised that just 3 units in the right positions would be enough for our house. Installation took 3 days , there was absolutely no mess and Luke and John with the help of Callum the electrician have done an amazing job. We cannot recommend Supreme highly enough and look forward to a cool summer this year. Thanks for everything and the five star rating is fully deserved. "

Simon Gibb

" Highly recommend them, all work completed was neat and tidy. Luke was always available to answer questions, can’t fault them "

Mr Frammingham

" We contracted Supreme Heating and Cooling to install several air conditioning units within our business premises. Luke visited our premises to measure up and advise on the best installation methods available to us (less visible and not so destructive to our leased office). From day one we had full confidence in Supreme Heating and Cooling based on Luke's friendly but professional approach (unlike other typical pushy salesmen that had come out previously). The whole process from quote to commissioning was very quick, efficient and hassle free. During the installation, the team at Supreme were very clean, tidy, and most importantly approachable and friendly. Apart from having a new addition on our walls (AC unit), you would not think any trades had been on site. We were recommended to go for the Mitsubishi system with Wi-Fi control and I must say that they are great! We use the system for keeping a constant temperature in our office space's during both summer and winter months. The additional Wi-Fi module also allows us to remotely connect to the system, which is particularly useful if you get home on a Friday and had forgotten to turn of the AC system for the weekend. The 7 year parts and labour warranty is also a huge plus! If you are considering a AC system from Supreme, I would certainly recommend them! "

CN Tech

" From the start Luke was very professional, he explained the system which he thought was best for us. He was quick to supply a quote which we found acceptable. Luke and Jodie turned up on time every day and got on with the job, they were both very polite and very clean. They made a lot less mess that expected and cleaned up every night. We would recommend them without any hesitation. "

David Gibbons

" Supreme provided an amazing service from the original quote right up until completion. Brilliant communication throughout and wonderful after care service as well. Luke and his team provided an exceptional service and the neatness of the installation was perfect. Supreme provided everything we asked for and more. We will definitely be using Supreme again. "

Philip Davies

" We had 6 Samsung aircon units fitted Very,very impressed with quality of the work and professional approach. Luke kept us informed all through the process. He arrived on time everyday and tidied up before leaving. Exactly what you want! I would highly recommend. "

Alan Roome

" Thank You Engineer Luke, Assistant Jodie and Electrician Spencer for terminating the overheating in our South facing bungalow. What an immediate change! Two Cool Dude’s in their 70’s HAPPY indeed. A professional installation, with questions answered and Seven years full warranty! While we had to bring cooling, it will be interesting to compare the heating abilities v our gas central heating in colder months? A professional job well done. Recommend them and for now the Government have made it all VAT! "

Peter Broadbent

" I don’t normally write comments on company’s pages, as I expect a good service when one pays good money – HOWEVER, very occasionally one gets exceptional service that really requires a note of thanks. The service we got from Supreme Heating and Cooling and, in particular, Luke Hersee is one of those that demand some feedback. From the moment he did the initial survey, offering advice and questioning what we wanted to achieve, to the moment he arrived exactly on the date and time we arranged and fitted the air con, the service was magic. I unreservedly recommend this company – and must add that this post is freely given!! Well done Supreme Heating and Cooling!! "

Mike Tingle

" From start to finish Luke was very professional, polite, nothing was too much trouble, we are very pleased with the installation, it’s very neat and done extremely well, cleaned up really well and took all packaging and rubbish. Also, we had 3 quotes, one a tad cheaper and one quite a bit more, but it was Luke we bought, many thanks for a great job. "

John Claxton

" After contacting Supreme for Air Conditioning for our home gym, we received seamless and professional service all the way from the initial quote, all the way until the job was complete. Couldn't recommend Luke and the Supreme team enough "

Adam Clark

" Luke and his mate (sorry I forgot your name) were in our home for three days installing air con in four rooms. They were always on time. Informative. Polite. Professional and so clean and tidy taking any rubbish away and leaving their work areas spotless. I can honestly say they were the most engaging tradies we’ve ever had working in our home. I would highly recommend your company to others. Great big thumbs up for the installers and the product. "

Shahn and Ian Ellis March, Cambs

" Excellent Samsung air conditioning system installed today by Luke. He was hard working,knowledgeable,clean and tidy. Very professional service,many thanks. "

Richard Broad

" I received several quotes but decided to go with Supreme after their very professional and efficient approach. After inspecting our premises, Luke recommended 2 larger units in our bakery and a smaller one in the shop. Due to our hectic schedule, we can only have work done on certain days of the week and Supreme were very accommodating to our needs and fit us in quickly. The work has been done to a very high standard and we are very happy with how it looks and works. Having aircon installed in the bakery has made a huge improvement and I would highly recommend Supreme for any air con needs. "

Daniel Hutton, Clever Cookie

" We had a system quoted and installed by the team at Supreme Heating & Cooling recently and I really cannot recommend them highly enough. The quote process was simple, they talked us through all the options and why they where suggesting the unit they did. The written quote then came through as promised on the day they said it would (very rare!). When it came to installation Luke was brilliant. Explained everything fully, demonstrated the unit and looking at the work after he left you can see he takes great pride in what he does (pipe routing, clips used), nothing uneven, nothing out of place. Very polite and completely cleared the area after the work was done. Really cannot say how impressed we are. Not to mention the huge reduction in the electric bill over the old under floor heating. "
