Things to check in Northolt
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
Conservation areas
Historic streets and listed buildings in and around Northolt are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Filters
Filters must be changed regularly to keep air flow and air quality up.
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.
