Mechanical Extract Ventilation (MEV) and Positive Input Ventilation (PIV) Servicing
Your MEV and PIV units are critical components that safeguard your property’s indoor air quality. Because these systems are mechanical, they require more than just superficial cleaning to maintain their effectiveness. At Mouldex, we deliver a technical, end-to-end service designed to maximise system longevity and energy performance. We move beyond standard maintenance by recalibrating airflow, verifying electrical compliance, and providing full certification—ensuring your assets remain protected and your compliance records are always up to date.
What’s included
Electrical check
We will test the fixed wiring and connections to the ventilation equipment to ensure safety and compliance with BS7671.
Installation Check
We check that the unit has been installed correctly, which keeps the system running efficiently and ensures your product warranties remain valid.
Valve & Motor Deep Clean
We thoroughly remove dust and grime from internal motors and air valves, helping prevent blockages and maintain performance.
Heat Exchanger Service
We clean the heat exchanger to maximise its ability to recycle heat efficiently.
Ductwork Check
We make sure all ductwork is tightly sealed, so moisture is properly extracted from the home rather than leaking into walls or ceilings.
Internal Duct Cleaning
We clear any dust buildup from inside the ducting.
Airflow Check
We recalibrate fan speeds to meet Approved Document Part F, ensuring the home has the right level of ventilation to prevent mould and maintain a healthy environment.
Filter Replacement
We replace old, clogged filters with new ones, allowing the system to run smoothly and maintain the best indoor air quality.
