What an AMC gives you
An AMC sets a schedule of preventive visits and often a defined response for breakdowns. It suits sites where an entry failure causes real disruption, such as communities, offices and busy docks.
When pay-per-visit works
A lightly used gate at a private home may do well with an annual check and repair only when needed. The risk is that small faults go unseen until they cause a stop.
Questions to ask
Ask what each visit covers, how fast the team responds, whether parts are included and what is excluded. Compare plans on these points and not on price alone.
