How much does HVAC design cost in Devon?
In Devon, guide prices run from about £515 to £2,550 per project, plus VAT. A typical job (design package for a 300–800 m² office) usually comes to £1,050–£2,550 plus VAT. Your exact price is fixed in writing before any work starts.
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.

Things to check in Devon
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 Devon 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.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Conservation areas
Historic streets and listed buildings in and around Devon are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Who we work with in Devon
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
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).

Why do I need a heat load calculation?
It sizes the system to what the room actually needs, avoiding oversized equipment that wastes money and undersized equipment that cannot cope.
Is the survey free?
For a straightforward installation, the survey and heat load are free with your quote. Full design packages for larger projects are charged and credited if we install.
