What to think about in Welling
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Working hours
Most Welling businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
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.

Do you also cover Bexley, Eltham and Thamesmead?
Yes. Alongside Welling, we also cover Bexley, Eltham and Thamesmead. Each has its own page with local guide prices.
Which postcodes do you cover in Welling?
All of them, including DA16. 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.
Will a new system be cheaper to run?
Usually. Modern inverter systems are considerably more efficient than equipment from 15–20 years ago, though savings depend on use.
