Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Conservation areas
Historic streets and listed buildings in and around Coulsdon are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Downtime
We schedule the swap to keep the space usable, often over a weekend.

Do you also cover Purley, Banstead and Wallington?
Yes. Alongside Coulsdon, we also cover Purley, Banstead and Wallington. Each has its own page with local guide prices.
Which postcodes do you cover in Coulsdon?
All of them, including CR5. 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.
