Filters and the unit need access for servicing — an access panel is non-negotiable.
Conservation areas
Historic streets and listed buildings in and around St Helens 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
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Working hours
Most St Helens businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
