A full MVHR service with ARC Facilities covers:
Visual inspection of the entire unit and ductwork
Filter removal, cleaning assessment, and replacement
Fan speed and airflow checks against commissioning data
Heat exchanger inspection and cleaning
Controls and sensor function test
Noise and vibration assessment
Documentation of findings and a written service report
Recommendations for any repairs required
Every service is carried out by NVQ Level 5 qualified engineers. We follow SFG-20 compliance standards and provide before-and-after documentation for your records — useful for landlord compliance, insurance, and warranty purposes.
Most MVHR systems should be serviced once every 12 months. In high-occupancy buildings, commercial properties, or environments with elevated dust or pollutants — such as near construction sites or busy roads — bi-annual servicing (every 6 months) is recommended.
Leaving an MVHR system unserviced leads to:
Clogged filters reducing fresh air supply
Increased energy consumption as the fan works harder
Accelerated wear on the fan motor, shortening the unit’s lifespan
Poor indoor air quality — a real health concern in residential blocks and offices
Warranty voidance on many manufacturer systems
Most people don’t realise that an unserviced MVHR system can increase a building’s energy use by 15–30% through reduced heat recovery efficiency. A £172 annual service protects a unit that costs £1,500 to £4,000 to replace.
We service all major MVHR brands across South East London. Pricing is the same regardless of brand — the complexity of access and the availability of filters may affect total cost where parts are required.

Book a service if you notice any of the following:
Reduced airflow — rooms feeling stuffy or poorly ventilated despite the system running
Unusual noise — grinding, rattling, or humming that wasn’t there before
Condensation on windows increasing inside the property
Higher energy bills — a blocked filter forces the fan to work harder
The unit hasn’t been serviced in over 12 months
Fault lights or error codes on the controller
