Before you book in Durham
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Working hours
Most Durham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
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.
Who we work with in Durham
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).

Do you also cover Chester-le-Street, Houghton-Le-Spring and Stanley?
Yes. Alongside Durham, we also cover Chester-le-Street, Houghton-Le-Spring and Stanley. Each has its own page with local guide prices.
Which postcodes do you cover in Durham?
All of them, including DH1. Give us your postcode when you enquire and we will confirm the visit details.
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.
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.
