How it works in Hertfordshire
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Hertfordshire we confirm access and parking beforehand.
Set positions
Cassettes are placed against the lighting and grid layout so air reaches the whole space.
Hang and connect
Units are hung on drop rods, connected to pipework and the condensate line.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Things to check in Hertfordshire
Condensate
Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.
Access and parking
Town-centre jobs in Hertfordshire 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.
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Working hours
Most Hertfordshire businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Typical premises in Hertfordshire
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
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.

Do you also cover Buckinghamshire, Bedfordshire and London?
Yes. Alongside Hertfordshire, we also cover Buckinghamshire, Bedfordshire and London. Each has its own page with local guide prices.
Do I need a suspended ceiling for a cassette?
Yes, or a ceiling void with access. In solid ceilings a wall-mounted or ducted unit is usually the better option.
Can a cassette bring in fresh air?
Many cassettes have a knock-out for a fresh-air duct, so ventilation air can be connected. The ventilation system still needs designing separately.
