The maintenance plan usually comes up at the end of a service call, or in a friendly phone conversation, or as a line on a bill that looks like everything else. It promises regular visits, priority booking, and fewer surprises. Some of that may be true. The part that decides whether it is worth it is written in the paperwork, and that paperwork is easy to skim when you are standing in a hallway with a technician waiting.

Find the renewal and the cancel lines first
Before you look at anything else, find two sentences: how the plan renews, and how it is cancelled. Look for words like 'automatic', 'renews unless', 'notice', and 'in writing'. Note how much notice is required, how you give it, and who is allowed to give it. If the cancel line says you must call, ask for the cancellation in writing and keep a copy in the folder with the rest of the paperwork.
Read what the plan leaves out
Every maintenance plan has an exclusions section, and that is where the real limits live. Read it slowly. Check whether parts are included or billed separately, whether after-hours calls cost extra, whether the plan covers the system you actually have or only the one the salesperson assumed, and whether repairs are covered or only inspections and tune-ups. Write the three exclusions that matter most for Mom's house on a sticky note and keep it with the plan.
Count the visits on paper
Plans often advertise a number of visits per year. Check whether that number is per system or per home, how the visits are scheduled, and what happens to unused visits. Ask whether a visit is a check-up or whether a repair call counts against the same allowance. If the answer is vague, ask for it in writing before you decide anything.
Check whose name is on it
A plan is tied to a person and an address. Find out whose name is on the account, who receives the reminders, and who can approve the visits when you are not there. Ask what happens if Mom moves, if the house is sold, or if the account holder can no longer manage the plan. Those are the situations where a plan is most likely to cause trouble, so get the answers before they become urgent.
Ask for the terms in writing before you say yes
Put these questions to the company, and ask for the answers in writing: how renewal works, how cancellation works, what the exclusions are, how visits are counted, whether parts are included, and how repairs outside the plan are priced and approved. If a clause is hard to understand, ask the company to explain it in plain words in writing. This is a practical check you can run yourself, not legal advice, and a company that cannot answer these questions plainly is telling you something useful.
Keep the folder together
Put the signed plan, the cancel instructions, the exclusions page, and the renewal reminder in one folder, with a note on the front naming who holds it. When the renewal notice arrives, you will know what to compare it against, and you will not be starting from memory on a busy afternoon.
