How we work in Carshalton
Heat loss survey
We assess fabric, glazing and ventilation to size for winter as well as summer. For sites in Carshalton we confirm access and parking beforehand.
Design
Units are chosen for their heating output at low outdoor temperatures, not just their cooling rating.
Install
Outdoor units go where defrost water can drain safely and air flow is not restricted.
Set controls
Schedules and set-backs are configured so the system heats efficiently.
Local points to consider
Air direction
Warm air rises, so units are set to direct air down when heating.
Leased premises
If your Carshalton 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.
Building fabric
Draughty or poorly insulated premises need more heating capacity; simple draught-proofing can reduce the size needed.
Working hours
Most Carshalton businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Premises we work in around Carshalton
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.

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).

Often not, but in some buildings a small back-up for the coldest days is sensible. We advise at survey.
