Describe what you notice
Note when the problem began, which rooms are affected, and whether the equipment starts, stops, or sounds different. You do not need to diagnose it yourself.
Gather accessible equipment details
A photo of the model label or an externally visible display can help. Do not remove panels or reach into equipment to find information.
Make access straightforward
Tell the team about access restrictions, pets, or construction activity. Clear a safe path to the equipment if you can do so without approaching hazards.
Bring your questions
Ask what the visit includes, how findings will be explained, and how additional work is approved. For planned installations, share drawings and photos before the assessment when possible.
