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.
Access and parking
Town-centre jobs in Welwyn Garden City often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
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.
Leased premises
If your Welwyn Garden City premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
