Local points to consider
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Working hours
Most Didcot businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Conservation areas
Historic streets and listed buildings in and around Didcot are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
