How it works in Hertford
Survey and route
We check void depths and plan routes for supply and return ductwork. For sites in Hertford we confirm access and parking beforehand.
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.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
What to think about in Hertford
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Conservation areas
Historic streets and listed buildings in and around Hertford 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 Hertford
- 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.
- 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.
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).
