Before requesting service
Write down the affected zones, when the issue appears and any controller messages. Include your city or ZIP code and whether the problem is active now. Avoid sending passwords, payment details or unnecessary personal documents.
Before arrival
Arrange gate access and contain pets. Locate existing manuals and invoices. Tell the provider about known underground work or inaccessible parts of the property without attempting excavation to expose equipment yourself.
Before approving work
Confirm any diagnostic fee, what requires additional authorization and how findings will be documented. Decide who can approve changes if you are unavailable during the visit.
Useful question
