A lot of modern houses are so well sealed now that have fancy mechanical ventilation systems
These are generally called PIV or Positive Input Ventilation Systems
PIV is basically a sophisticated whole home ventilation and condensation control units designed to combat these problems by gently ventilating the home from a central position on the landing in a house or the central hallway in a bungalow or apartment.
They are Energy efficient, the units introduce a subtle air supply throughout the house to transform a stagnant, stale atmosphere into a fresh, healthy, condensation free environment
But did you know they have filters that need changing every 2 years?
Can we help?
