If it's top class service you are wanting look no further than this one stop shop, you won't be disappointed. 5 star plus service.

These guys are amazing, very professional. The job was done over a few days, but each day our club was left clean and safe. The aircon systems are great, the guys gave us a full guide of how to run the appliances.

Fantastic job, thank you.

Dean Lancashire

Couldn't recommend this company enough. Craig quoted quickly and explained what was required. The Sub Zero team came and installed the kit rapidly in temperatures close to 30c in our loft bedroom and were very tidy and professional on completion. Thank You

Walden Effingham

The Sub Zero team were very helpful and efficient when they fitted our air con unit in our conservatory. 3 years later when there appeared to be an electrical problem they were again very helpful in attending and providing a solution. Recommended.

Ian Palmer

The guys at Sub Zero excelled themselves throughout the whole process. SubZero assured me that the job was well within their capabilities. Even though they had suggested a slightly larger unit the price was still comparable with other quotations I had received. On the day of installation the whole process was over and completed within the morning.

I cannot recommend Craig and the Sub Zero guys highly enough
