How much does it cost to replace air conditioning in St Albans?

Air conditioning replacement is removing an old system — often one using R22 or R410A refrigerant — and installing new, more efficient equipment, re-using pipework where it is safe and compatible.

Before you book in St Albans
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Conservation areas
Historic streets and listed buildings in and around St Albans are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
