How a job in Carshalton works
Measure
We measure the opening and check wind exposure and existing heating.
Select
The right width, air velocity and heat source are chosen.

The unit is mounted and connected to power, water or refrigerant. We keep work areas in Carshalton screened and tidy at the end of each day.
Set up
Door contacts and controls are set so it runs only when needed.
Local points to consider
Heat source
Heat pump air curtains are usually cheaper to run than electric ones.
Working hours
Most Carshalton businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Sizing
The curtain should cover the full door width and reach the floor at the right velocity.
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.
Typical premises in Carshalton
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.

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.
