  4. Install and commission

    New units are fitted, tested and commissioned with fresh records.

Local points to consider

Downtime

We schedule the swap to keep the space usable, often over a weekend.

Roof and height work

Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.

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.

Types of premises we cover in Darlington

Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.

Yes. Alongside Darlington, we also cover Newton Aycliffe, Yarm and Stockton-on-Tees. Each has its own page with local guide prices.

Which postcodes do you cover in Darlington?

All of them, including DL3 and DL98. Give us your postcode when you enquire and we will confirm the visit details.

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.

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.
