Downtime
We schedule the swap to keep the space usable, often over a weekend.
Leased premises
If your Redhill 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.
Conservation areas
Historic streets and listed buildings in and around Redhill are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
