An HVAC design and heat load survey works out how much heating and cooling each space needs — from occupancy, equipment, lighting, glazing, orientation and the building fabric — and sets out the system type, unit sizes and positions, pipe and duct routes and controls in a written specification.

Working in Coulsdon

Premises in Coulsdon are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.

That includes premises in CR5 and the surrounding districts. We also work in nearby Purley, Banstead and Wallington. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

What we do

  • Room-by-room heat gain and heat loss calculations
  • System options with pros, cons and budget costs
  • Layout drawings for units, pipework and condensate
  • Noise data for planning or landlord approval
  • Written specification for pricing

Before you book in Coulsdon

Diversity

Not every room peaks at once; good design accounts for diversity so central plant is not oversized.

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.

Future use

Allow for growth in occupancy or IT load.

Leased premises

If your Coulsdon 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.

Who we work with in Coulsdon

  • Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
  • Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.

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.
