The steps for a project in Portsmouth
Survey and route
We check void depths and plan routes for supply and return ductwork.
Design the air side
Grille sizes and positions are chosen for even air flow and low noise.
Install unit and ducts
The unit is hung with access for servicing; ductwork and grilles are fitted. We keep work areas in Portsmouth screened and tidy at the end of each day.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
Before you book in Portsmouth
Return air
Every ducted unit needs a return air path; we design it rather than rely on gaps under doors.
Conservation areas
Historic streets and listed buildings in and around Portsmouth are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Void depth
Low-profile ducted units can fit voids of around 250 mm, but ductwork adds depth. We measure the route as well as the unit position.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Typical premises in Portsmouth
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
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.

How much ceiling void is needed?
Low-profile units can work in around 250–300 mm, but the duct route often needs more. We measure at survey.
Is ducted AC quiet?
It can be the quietest option, because the unit is away from the room. Correct duct sizing and attenuation make the difference.
