Products & Services


From time to time equipment can fail, when this happens our qualified Engineers have the experience and diagnostic know-how to find the fault and put it right for you with minimal downtime.

Call our team to arrange a call out on 0800 019 6025 and they will arrange for an engineer to be with you as quickly as possible.

To keep costs transparent and straight forward we operate a 2 hour “window” on call outs. If we cannot remedy the fault within this time we will provide you with a full report of the problem and the likely cost of the repair.

Regular maintenance is oftenoverlooked because of the cost, but overlooking this can be more much more expensive in the long term. A regularly serviced system will run more efficiently and in turn be more cost effective. Faults are identified early, helping avoid disruptive and potentially expensive repairs - most importantly the life span of the equipment willincrease if regularly serviced. We provide a wide range of air conditioning maintenance and servicing options and can design a bespoke package that suites your needs.
