What to think about in Stevenage
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
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.

Yes. Alongside Stevenage, we also cover Hitchin, Letchworth Garden City and Welwyn Garden City. Each has its own page with local guide prices.
Which postcodes do you cover in Stevenage?
All of them, including SG1. 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.
