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.
Covering Seaham and nearby
Most commercial premises in and around Seaham are shops, offices, salons, pubs and small industrial units. Sunderland is about 8 km away.
We work across Seaham's postcode districts, including SR7. We also work in nearby Houghton-Le-Spring, Sunderland and Peterlee. Buildings across County Durham 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
- Electrical load and supply requirements
- Written specification for pricing

Before you book in Seaham
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Access and parking
Town-centre jobs in Seaham 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.
Typical premises in Seaham
- 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.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
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).
