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