Excellent maintenance program and quick service. Andy was a pleasure to deal and Keiran who visited today was a knowledgeable & friendly engineer. Thank you
From initial contact, the service and communications have been excellent. We have had a large unit fitted, all done in just two days. It has been a very neat and effective job. Work was carried out by the two ‘Dan’s’ who have been a pleasure to have had in the house. Well done Kool-It.

Got Questions?
We’ve Got You Covered!

Kool-It Services Limited is a small, customer focused, company comprising of twenty staff (most of which are time served, fully qualified, refrigeration and air conditioning engineers). All our staff are directly employed by us – as we believe they should be. The only way to nurture good engineers is to keep them in-house.

Kool-It offers all aspects of refrigeration and air conditioning engineering – tailor made to suit your needs. Most of our work is Manchester and North West based but we can, and frequently do as our rates are often lower than Southern contractors, travel further afield for installations and service work. Our maximum in-house job size is around the £250k mark.
