Before you book in Farnworth

Hygiene

Drip trays and coils must be kept clean to avoid biological growth.

Leased premises

If your Farnworth 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.

Filters

Filter grades should match the original design or current guidance for the building.

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.

Premises we work in around Farnworth

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.
