Which postcodes do you cover in Eltham?
All of them, including SE9. 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.
Can existing pipework be re-used?
Often, if it is the right size, in good condition and compatible with the new refrigerant. We test and flush it before relying on it.
