Heat-recovery ventilation
Centralised equipment, including Mitsubishi Electric Lossnay, considered with duct routes and air distribution.
VENTILATION · DARTFORD & KENT
Fresh-air systems planned for the building.
Ventilation installation, servicing and repair for homes and small-business premises, including heat-recovery systems and Mitsubishi Electric Lossnay.
InstallationVentilation requirements, routes, terminals, controls and access are considered at survey.
Service & repairExisting systems can be checked, maintained and investigated when performance changes.
Heat recoverySuitable systems transfer energy between outgoing and incoming air streams.
FRESH AIR & EXTRACTION
Ventilation is a system, not a single box.
Effective ventilation depends on the building, occupancy, air paths, ductwork, terminals, controls and access for future maintenance. We start by understanding the space and what the existing or proposed system needs to achieve.
Heat-recovery ventilation can provide controlled fresh air and extraction while transferring energy between the outgoing and incoming air streams. The actual design and suitability must be confirmed for the property.
Commercial fresh air
Ventilation for offices, shops and other smaller commercial spaces, subject to survey and design.
Existing-system servicing
Checks and maintenance for filters, accessible components, airflow paths and general operation.
Fault finding & repairs
Investigation where ventilation is noisy, not operating, showing a fault or no longer performing as expected.
SITE INFORMATION

- Proposed intake and exhaust locations
- Controls and operating requirements
For service or repair
- Manufacturer and model if known
- Number and location of units
- Fault code or controller indication
- Filters and last maintenance date
- Description of noise, airflow or operating problem
COMMON QUESTIONS
Useful answers before you enquire.
Is ventilation the same as air conditioning?
No. Air conditioning primarily controls room temperature, while ventilation introduces or removes air. Some buildings require both systems.
What is heat-recovery ventilation?
It transfers heat energy between outgoing and incoming air streams, helping reduce the energy otherwise lost through ventilation.
Can you service an existing Lossnay system?
Yes, subject to the equipment, access and condition. Send the model number and photographs if available.
Can ventilation be priced without a survey?
New ventilation installations normally require a survey because duct routes, air terminals, access and the building requirements all affect the design.
