Which postcodes do you cover in Castlereagh?
All of them, including BT5 and BT6. Give us your postcode when you enquire and we will confirm the visit details.
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.
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.
