Local points to consider
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 Hatfield businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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 Hatfield are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.

Will a new system be cheaper to run?

Not necessarily. If an R410A system is working well and maintained, keep it. Plan replacement when it becomes unreliable or expensive to run.
