We have been in business a long time, and most of our customers have been with us for years. Lewis is known for his attention to detail and his close relationship with his clients, continuing to work with his clients long after installation, ensuring the equipment is running efficiently and maintained to the highest standard.

I have had Celtic Cooling on site from construction in 2003 to date, I have no hesitation in recommending them to anybody requiring a dependable and trustworthy contractor

This is based on a few things; cost, response-time and quality of work.

Barry himself is not just about making money but would have the clients interest at heart.

We have engaged the services of Celtic Cooling for over five years, for air conditioning, units for our controlled temperature warehouse, and freezer and chill room.

Their commitment to service and addressing any emergency call out requirements is excellent with a very good response time.

We highly recommend Celtic Cooling to any potential client as a business who works with their clients and develops and understanding of their business and needs.

We have always received first class service from Celtic Cooling who have installed and serviced fridges, freezers and air conditioning units in our 3 Subway restaurants.

Above all they have always made us feel like a valued customer.

We have highly recommended Celtic Cooling to all other Subway Franchisees.

Here at Kildare Farm Foods we have been dealing with Celtic Cooling for 10 years and are delighted to have such a consistently reliable supplier. Supplying all our refrigeration needs from retail to large scale industrial solutions.

Celtic Cooling has always given us sound advice and maintenance support that is second to none, providing round the clock on call assistance.

Celtic Cooling installed an alarmed temperature monitoring system for us some years ago which alerts us by telephone should temperatures fall outside acceptable parameters, this system gives us the piece of mind to ensure that refrigeration within our premises is seamless guaranteeing the integrity of our cold chain.  Given the critical nature of refrigeration to our business I cannot understate the importance of forging a partnership with a quality supplier such as Celtic Cooling and cannot recommend their work enough.
