Local points to consider
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
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.
Summer bypass
A bypass avoids warming incoming air in summer.
Conservation areas
Historic streets and listed buildings in and around Chelmsford are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
