Before you book in Carshalton
Old refrigerant
Systems still on R22 cannot legally be topped up with virgin or recycled R22. Repairs on these are limited — replacement is often the realistic option.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Switch it off
If water is coming through a ceiling or the unit is tripping, switch it off at the isolator until it is checked.
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.
