xchange air removed a poor ventilation system form under our house and installed a much higher quality one. They provided a free site visit and made a clear and simple recommendation as to how to improve on the system we had.
The new system is much quieter, in a more appropriate location and can be easily controlled with a timer plugged into an internal wall socket.
The price also seemed quite reasonable.
