Before you book in Gwynedd
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Conservation areas
Historic streets and listed buildings in and around Gwynedd are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
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.
