Residential ventilation plays a vital role in maintaining appropriate air movement in modern homes and
apartment developments. L-D-N supports landlords, residents and managing agents with inspection,
maintenance and technical assessment of ventilation systems.
Systems we support
- Mechanical Ventilation with Heat Recovery (MVHR)
- Mechanical Extract Ventilation (MEV)
- Continuous extract and apartment ventilation systems
- Common ventilation components and associated controls
Typical maintenance tasks
- Check filters and advise replacement intervals
- Inspect fans, heat exchangers and accessible duct connections
- Check condensate arrangements and visible signs of leakage
- Review operating settings and controls
- Assess airflow where suitable instruments and access are available
- Identify noise, reduced performance, contamination and other defects
- Produce property-level or portfolio-level findings
High-rise and portfolio servicing
For managing agents responsible for multiple dwellings, we can structure access programmes, service schedules,
resident communication requirements, unit registers and consolidated defect reporting.
Important scope notes
Cleaning, balancing, fire-damper works, intrusive duct access, specialist testing and remedial replacement are
not assumed to be included unless expressly quoted. Work in occupied homes requires agreed access,
safeguarding and resident protocols.
Maintenance outcomes
The aim is to identify preventable issues, maintain suitable equipment performance and provide clear
recommendations rather than promise a specific indoor air quality result.
Call to action
Request an MVHR / MEV Maintenance Proposal — Enquire about your building, asset schedule, location and
required service. We will review the scope and respond with appropriate next steps.
