I'm really pleased that I selected Coolheat Services Limited to install air-conditioning/heating into my retail store. Very courteous engineers who completed the work within the stated time schedule with the minimum disruption. I would certainly recommend your company to others requiring similar installations.

Britvic Soft Drinks Ltd

You will not find a more professionally conducted company anywhere. From the site engineers to the to the office staff. They have never let me down in the many years I have had the pleasure of dealing with them. All paper work is first class from RAMS to waste transfer details and the compliance of the engineers to site health and safety regulations is second to none. I have no hesitation in recommending Cool Heat services.



A family run business that is a pleasure to deal with. We have used them for many years to design, install and service our air conditioning systems around the country. They are happy to visit sites and suggest best solutions. The works are carried out on time and installations are to a high standard. No hesitation in recommending them.

I have been using Cool Heat Services for around 12 years now for the reactive and planned prestige Regional Distribution Centre. They have also installed some additional split systems for our Server rooms. I am happy to recommend Cool Heat Services to any potential new customer, as I have received a high standard for customer service to date.
