Prepare a short equipment history
Have the manufacturer and model handy. Record any noise, error codes, recent service, and changes in output. Tell the technician if the unit shares equipment or supply with another part of the building.
Ask what the technician checks
The scope depends on the unit and visit. It can include checking visible connections, signs of leakage, the unit’s operation, and equipment-specific maintenance needs. Use a qualified professional for internal, gas, and electrical work.
Get a clear record of the result
Ask which items need attention now and what can be planned later. Keep any recommended work, equipment details, and expected maintenance intervals with your service history.
