I just want to email to say thank you very much! We have worked with many contractors over the years and working with you and your team has been really enjoyable. Your boys are extremely polite, approachable and helpful. It has been a real pleasure to work with them on this.
The garage conversion is due to commence next week so once the structure is done, I'll let you know as we will require the same AC units for the office there. But of course, I will be in touch as and when.
Thanks again!
Kind Regards,

Simran Luthra, Kennet Property

Recently had air conditioning installed, and just in time for Christmas. Couldn't be happier with the result we've never been so warm! The chaps that came to fit it were so polite, very impressed with the whole service from quote to installation.

Blue Mountain installed an air conditioning unit in the study. Extremely professional service, looks really neat and it's perfect for the hot summer days. Very happy customer, highly recommend this company.


Blue Mountain Air Conditioning installed 2 x units in my home recently. Excellent service by the engineers, speedy and very clean. Polite boys who gave us good instructions on how to use the air conditioning. Well impressed and would recommend them to anyone looking for Air Conditioning. Our house has never been so warm and it is economical to run, a lot cheaper than gas prices.


I had air conditioning fitted throughout my upstairs bedrooms. The Engineers were professional, clean and knowledgeable. I decided to go for a ducted unit as it looks far more aesthetically pleasing and I am super pleased with the results. My heating bill has already reduced and I would recommend Blue Mountain to anyone


Excellent job, carried out by an expert team quickly and efficiently, with no fuss and absolutely no inconvenience. All of the team were extremely polite and helpful and left the property tidier than it was when they arrived. The Mitsubishi equipment is clearly top quality, and worked perfectly with no complications, and everything was explained in clear and easy to understand terms. Exactly how you would hope a property modification would be executed. I was very pleased with how smoothly things went from start to finish, including the initial survey which made an installation that could easily have seemed complex sound uncomplicated and straightforward, as it proved to be.

Blue Mountain provided excellent advice, during purchasing without any pressure or upselling. Installation was stress free, quick and easy as well as diligent and comprehensive. We were left with the right system at a good price. Simply excellent.

Blue Mountain fitted an air con unit for our kitchen. The job was carried out to plan and undertaken on the date agreed. Paul and Dominic did a great job and cleaned up the area as they worked. The bill reflected the quote so no surprises and Steve called to follow up and ensure everything was done ok. Great customer service. Would highly recommend this company.
