Points to plan for in Caernarfon
Smells
Musty smells usually mean biological growth in the coil or tray; a deep clean and drain treatment normally cures them.
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.
Grease
Units near kitchens need cleaning more often, and sometimes relocating.
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.
