Before you book in Isleworth
Switch it off
If water is coming through a ceiling or the unit is tripping, switch it off at the isolator until it is checked.
Access and parking
Town-centre jobs in Isleworth often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Old refrigerant
Systems still on R22 cannot legally be topped up with virgin or recycled R22. Repairs on these are limited — replacement is often the realistic option.
Leased premises
If your Isleworth premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Premises we work in around Isleworth
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Which postcodes do you cover in Isleworth?

Is it worth repairing an old system?
If it uses R22, has repeated faults or needs a compressor, replacement is often better value. We give you both options.
Can you just re-gas it?
Re-gassing without finding and fixing the leak only delays the problem. We locate and repair the leak, then charge the system and record the quantity.
