Eliminate condensation and mould throughout your home with a professionally installed Positive Input Ventilation system. We fit and commission PIV units in lofts with discreet ceiling diffusers.
PIV is the most effective whole-house ventilation solution for properties suffering from condensation, mould, and poor air quality. A PIV unit mounted in the loft draws filtered fresh air from outside and gently pressurises your home, pushing out stale, humid air through trickle vents and natural gaps. We install the unit, run insulated ducting, fit the ceiling diffuser, wire the heater and controls, and commission the system to ensure balanced, draught-free airflow. Ideal for older properties, homes with solid walls, and rental properties where tenant habits cause damp.
Why Choose RTS for PIV Unit Installation?
