Covering Cardiff and nearby
Cardiff has the full mix of premises that need cooling and heating: offices, shops, restaurants, gyms, clinics and technical rooms.
That includes premises in CF10, CF11, CF14, CF15, CF23 and CF24 and the surrounding districts. Nearby, we also cover Penarth (about 5 km), Caerphilly (about 11 km) and Barry (about 11 km). In Cardiff we work with offices, shops and hospitality premises, from a single room to a whole floor; each job starts with a heat load check rather than a guess from the floor area.
Included as standard
- Condition survey of the existing system
- Refrigerant recovery with waste transfer documentation

Install and commission
New units are fitted, tested and commissioned with fresh records.
What to think about in Cardiff
Downtime
We schedule the swap to keep the space usable, often over a weekend.
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.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Who we work with in Cardiff
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- 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.
Two rules matter for most businesses in Wales: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
