 Trustindex verifies that the original source of the review is Google. Absolutely outstanding service from ClimaChill, and especially from Scarlett.

From the moment I contacted the team, Scarlett went above and beyond to help me with my air conditioning unit. Her work ethic, professionalism and willingness to help were genuinely impressive. She was incredibly friendly, patient and knowledgeable, and made sure that my issue was dealt with properly rather than simply brushing it aside.

It’s rare to come across someone who clearly takes so much pride in their work and genuinely cares about giving customers a great experience. Scarlett is a real credit to ClimaChill and deserves recognition for the effort she puts in.

I wouldn’t hesitate to recommend ClimaChill to anyone, and if you’re lucky enough to deal with Scarlett, you know you’re in good hands

As well as being very efficient he is very knowledgeable and has helped us as we are planning a second unit.  We really enjoy seeing him.

From installation through to ongoing maintenance I have found all at Climachill to be most helpful and efficient in all of my dealings with them. We have had no issues whatsoever with our system that they installed and it has been extremely effective in managing costs both in summer and through the winter whilst keeping us cool and warm respectively.

Climachill fitted full air conditioning to our office premises which is a converted barn in Glynde near Lewes. We received the highest level of service right through from them providing a very competitive quotation through to the complete installation. It has transformed our working environment when we end up with extreme temperatures at either end of the scale and so much so that I have installed an air conditioning system at my own house, again which Climachill have completed to an excellent standard.

Managing Director, Blockbusters Contracts, Glynde

Many thanks for carrying out such a quick and professional job here last week, we are pleased that we chose Climachill over the competition for our air-conditioning installation. As for your competitors, we chose Climachill not only because, on a like for like basis (5&7kw units) you were cheaper but because you came across as the most professional when you visited us initially to make the site survey and discuss our requirements.

Martin Smith

Sales Director, Ultimate Automation, Partridge Green

We would like to thank your company for the reliable service provided with our air conditioning systems over the last few years. The original purchase was handled smoothly and you have always been most accommodating whenever we have needed further assistance. During our recent renovation, your company was easy to contact, quick to respond and most helpful in relocating the equipment.

Practice Manager, Ashley Road Dental Practice, Walton-on-Thames

After contacting several Air Conditioning Suppliers who failed to turn up, I managed to locate Climachill who carried out a site survey and installed the air conditioning to regulate the temperature in my server room, all within 21 days of the initial contact with minimal disruption. This included the installation of additional electrics to cope with the extra power draw from the 3 air conditioning units and the removal of a double glazed window for the triple extraction system. I have found Climachill’s service efficient and professional and have no hesitation in recommending them.
