Not an F-gas check
A TM44 inspection is about energy efficiency. It does not replace F-gas leak checks or servicing.
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.
