Things to check in Witham
Filters
Filters must be changed regularly to keep air flow and air quality up.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Types of premises we cover in Witham
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.

Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
