1st cool were extremely professional from start to finish.

I was dreading the installation and the implication and disruption it would bring, but contrary to what we were expecting 1st Cool were amazing, they went about their job with minimal disruption, at times we forgot they were here.

It was an absolute pleasure and a refreshing change to have a company do what they promised!

Thank you so much.

A very neat and tidy install, I was very impressed with engineers, they took their shoes off in the house, used a hoover and dust sheets when cutting holes etc. Absolutely Faultless.

1st Cool supplied and installed my air conditioning about 5 years ago and it has been serviced by them regularly since then.
Their engineers turn up at the time booked, carry out the service with the minimum of fuss and leave everything working perfectly and leave no mess behind.
a first rate service from an excellent company, thank you 1st Cool

We have used the services of your company for over 20 years. During this time, we have received the most fantastic service. Your staff and yourself have always been professional and 1st class.
The recent replacement of our air con unit was seamless from the point of ordering right through to installation. Your engineers left our site extremely tidy and clean. The new unit has been much needed this time of year, so thank you for your prompt service. We shall continue to use your company for when our unit needs servicing.

I would like to thank you for the superb job you did on fitting our air conditioning in the kitchen.
I always feel that it's a bit of a concern when having workmen in my home. I am pleased to say that from our first discussion regarding the fitting of the air con unit, you took all the details and the results are perfect. The unit was fitted, quickly and efficiently with no mess or hassle.
There are many comments we could add about the professional service, reliability and your polite and friendly staff. We are more then satisfied and would not hesitate to recommend you or your company to any potential customers.
We have had a lot of admiring and envious comments from our neighbours and friends. Again many thanks

1st Cool Ltd were recommended to me by RDG Builders who helped with the refurbish to the new Stanford office and they liaised with RDG regarding the works, this was of a great help to me due to the fact that I did not have any knowledge of air conditioning/heating.
The work was carried out with the minimum disruption to the other works that were being carried out at the time and every worker was polite and professional in their manner. The works carried out on the time that was agreed and finished to the highest standard.
I would not have any hesitation in recommending this company to anyone who requires this kind of service for their places of work or home.

We have been using 1st Cool for the last year for our air conditioning. We needed something to cool and heat our office, so Dave at 1st Cool suggested an air conditioning unit. They came out and fitted one very quickly and did so without disturbing our office work so we could carry on working around them. The unit is perfect for our needs. They were also quick to come out and fix the issue we had with our unit without any problems.
The staff at 1st Cool are all very helpful, friendly and efficient, making dealing with them an ease. I would not hesitate to recommend 1st Cool to anyone.

I have the pleasure to recommend 1st Cool Ltd, who I have used on several occasions.
Having worked with Dave at 1st Cool Ltd for the past 3 years I have always been completely satisfied with their quality of workmanship and professionalism. Its been a pleasure to work with them on a variety of projects including the recent installation at a residence in Grays, Essex. The quality, standard of the products and fittings were all superb.
I have no hesitation in highly recommending your company to everyone and look forward to a continued professional relationship with 1st Cool Ltd.
