Jesse Jenkins
Brilliant service from start to finish from Sub-Zero Refrigeration & Air Conditioning Ltd. James came out to do the survey really professional and helpful. The installation was carried out by Stefan and Hywell, who were both polite, tidy, and did a fantastic job. Everything was left clean and running perfectly. Couldn’t be happier with the whole experience! More...

We decided to go with James and his team and honestly it was the best decision we have made (just in time too) , this wall-mounted AC has been a game-changer. Super easy to use, cools the room down in no time, and it’s surprisingly quiet even on the higher settings. Looks neat on the wall too, not bulky or in your face. Perfect for keeping cool during the summer and it even takes the edge off in winter with the heating mode. Definitely one of the better home upgrades I’ve made! More...

Anthony
Sub-Zero Refrigeration & Air Conditioning Ltd have been amazing from start to finish. The installation was quick, clean, and professionally done, but what really stood out was the aftercare. They followed up a few days later to check everything was running smoothly and took the time to answer all my questions. It’s clear they genuinely care about their customers. The AC system works perfectly and has made a huge difference in the comfort of our home. Highly recommend — not just for the install, but for the top-notch service that comes after. More...
