Before you book in Barnet
Downtime
We schedule the swap to keep the space usable, often over a weekend.
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.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.

Which postcodes do you cover in Barnet?
All of them, including EN5. Give us your postcode when you enquire and we will confirm the visit details.
Should we replace R410A systems now?
Not necessarily. If an R410A system is working well and maintained, keep it. Plan replacement when it becomes unreliable or expensive to run.
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.
