From enquiry to handover in Harpenden
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork.
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. We keep work areas in Harpenden screened and tidy at the end of each day.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Local points to consider
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
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.
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Access and parking
Town-centre jobs in Harpenden 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 Harpenden
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.

- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
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).

Which postcodes do you cover in Harpenden?
All of them, including AL5. Give us your postcode when you enquire and we will confirm the visit details.
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.
What size cassette do I need?
It depends on the heat load. As a guide, a compact cassette suits a room of up to about 40–50 m² of office space; larger spaces use bigger units or several cassettes.
