The garage door is often the largest moving object at the house, and it is usually the route Dad takes into the kitchen. A service visit is not about making the opener quieter. It is about confirming the door stops and reverses when it should, and that the manual release works when the power is out. Set up the visit so those checks are on paper.

Before the visit
Find out who in the house uses the opener, and whether the remote and keypad are the ones Dad actually carries. Note any sticking, slow reversal, or door that stops halfway. Ask whether the technician is licensed for the work and whether the company carries liability insurance. Ask them to bring the equipment to test the reversal force on the spot, not just to look at the opener.
During the visit
Ask the technician to demonstrate the auto-reverse on an object placed on the floor under the closing door, and to show the sensor beam being interrupted and the door reversing. Watch the sensor alignment and ask them to explain what they changed. Ask them to test the manual release cord: it should be reachable from the driver's side, and the door should lift and fall freely once released. Check the tracks, the rollers, the hinges, and the cables for visible wear. Springs and cables are under tension and must be handled only by a licensed technician, so do not let anyone in the family adjust them.
What the work order should say
The work order should list each test by name: reversal test, photo sensor check, manual release check, track and roller inspection, and the remote programming. If the sheet says service complete with no detail, ask for the list before you pay. Keep the paper with the house folder so the next person to call knows what was checked.
Between visits
Monthly, look at the sensor lenses for dust or spider webs, confirm the door reverses when a light object is placed under it, and check that the release cord has not been hooked or pulled loose. These checks are simple and they tell you when the service call is due earlier than planned.
Your next move
Call the service company this week, ask for a visit that covers the reversal test, the sensor, and the manual release by name, and request the written list before the technician leaves. Put the appointment on the calendar with Dad's usual entry time so the door is not in use while the work happens.
