Quality System for Sub Floor

We have a large undercroft area which was damp and musty. Since installing this system, the smell has gone and it has extracted all the humidity and stale air. Installation guide provided was extremely helpful also.

Good Product and Good Service

I contemplated making my own system but after trialling a fan from a major hardware store decided to look for something quieter. The staff at Fresh Ventilation were helpful in making suggestions on the layout and size of the system over the phone and were flexible in making changes to the kit to suit my requirements. The instructions for installation were super easy to follow and the system has worked perfectly since installation and improved our house.
