Points to plan for in Dereham
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Leased premises
If your Dereham 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.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Working hours
Most Dereham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
