Points to plan for in Gwynedd
Summer bypass
A bypass avoids warming incoming air in summer.
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.
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
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.
Who we work with in Gwynedd
- 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.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
Compliance in Wales: 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).
