Before you book in County Durham
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Conservation areas
Historic streets and listed buildings in and around County Durham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Leased premises
If your County Durham 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.

What happens to the old refrigerant?
It is recovered into certified cylinders and sent for reclamation or destruction, with the paperwork kept on your records.
Is it illegal to use R22 air conditioning?
No — you can keep running an R22 system, but it cannot be maintained with virgin or recycled R22, so most repairs involving the refrigerant circuit are no longer possible.
