Book your MVHR service | 24/7 emergency callout | Request an energy survey
Poor airflow, persistent humidity, noisy ventilation, or rising energy bills are all signs your MVHR system needs attention. ARC Facilities’ certified engineers service domestic and commercial MVHR units across London, Essex, and Kent—backed by Trustmark, CHAS, SSIP, IWFM, and ECMK credentials. With a rapid emergency response and a 6-month warranty on repairs and installations, we keep your ventilation efficient, quiet, and compliant.
Mechanical Ventilation with Heat Recovery (MVHR) systems provide continuous fresh air while recovering heat from extracted air. Regular servicing ensures:
Energy efficiency: Maintains heat recovery performance and lowers bills.
Reliability and lifespan: Identifies wear before failures and expensive repairs.
Residential: Full service every 12 months; replace/clean filters every 3–6 months depending on environment.
Commercial and large HMOs: Service every 6 months due to higher occupancy and runtime.
Signs you’re overdue include a unit not running, fan failure warnings, excessive noise or vibration, stale/damp smells, and visible dust build-up on grilles.
Our engineers work to a structured, SFG20-aligned process. A typical visit includes:
Visual inspection: Check ductwork, seals, silencers, and condensate drains for damage or blockage.
Electrical and fan tests: Verify supply, speed settings, bearings condition, vibration levels, and safety isolation.
Heat exchanger: Remove, clean, and inspect for fouling or damage; re-seat with correct seals.
Filters: Replace/clean; measure pressure drop and note filter grade/type.
Airflow balance: Spot-check supply/extract flows; adjust dampers; check boost/occupancy controls; optional CO₂/IAQ spot readings.
Controls and sensors: Test timers, boost, humidity/temperature sensors; review and clear fault logs.
Drainage: Flush condensate lines; confirm traps/gradients.
Hygiene and sealing: Clean internal compartments and replace perished gaskets where required.
Documentation: Provide a service report with before/after photos and recommendations.
Transparent pricing: Standard MVHR servicing starts from £170.
What can affect price: Access constraints, filter grade/type, heavy fouling requiring deep cleaning, replacement parts (e.g., fans, sensors), and complex airflow balancing in large properties.
Warranty: We provide a 6-month warranty on all repairs and installations.
Unit not running: Electrical faults, control settings, or motor issues.
Fan failure: Worn bearings, seized motors, or PCB faults.
Excessive noise: Imbalance, loose fixings, or clogged filters causing strain.
Poor airflow: Blocked filters/ducts, incorrect balancing, or heat exchanger fouling.
Condensate issues: Blocked drains causing leaks or odours.
We diagnose quickly—most visits take around 1 hour for servicing or fault-finding, minimising downtime.
Our servicing approach aligns with SFG20 guidance where applicable. For sites targeting improved EPC ratings or net‑zero goals, we also offer energy surveys and recommendations to reduce consumption and improve indoor air quality.
We service MVHR systems across London, Essex, and Kent, with expansion to UK-wide services planned. Include your postcode when booking for the fastest scheduling.
