Local points to consider
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 Chester-le-Street 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.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Working hours
Most Chester-le-Street businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
