Local points to consider
Refrigerant leaks
Topping up without finding the leak is a false economy and, for systems above the threshold, a breach of F-gas leak repair duties.
Conservation areas
Historic streets and listed buildings in and around Sunbury-on-Thames are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Switch it off
If water is coming through a ceiling or the unit is tripping, switch it off at the isolator until it is checked.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
