Many service contracts make the owner responsible for certain upkeep. The contract may not call it maintenance. It may appear as a duty in the owner section, as a condition in the coverage grant, or as a reason a claim can be denied. Read each duty as a trigger and a record.
Turn each duty into a trigger
A trigger is the condition that starts the duty. It may be a distance driven, a length of time since the last service, a reading on a gauge, the age of a part, or a visible condition. Write each trigger on its own line, with the section number of the contract where the duty appears. Where a trigger is vague, such as 'as needed' or 'when worn,' write the question you would need to ask the seller to make it checkable.
Decide what record proves it
For each duty, decide what paper or dated entry would show that it was done. Common forms are a receipt, a service invoice, a written log, or a photograph of a part label. Keep the record with the contract, not only in a phone or an email account. Ask the seller whether it accepts a record from any qualified person or only from a specific provider, and get the answer in writing.
Check who may perform the work
Some duties may be done by the owner. Others may need a licensed or authorized provider. Read the repairer section and the owner section together. If the owner-repair clause limits what you may open or adjust, a routine check may still be allowed, so ask which tasks fall on each side of that line.
Keep the duties through a change of owner
A sale, a transfer, or a change of household can change who must perform a duty. Note whether the duties follow the contract, the unit, or the original owner. Put that note with the transfer paperwork.
What this guide does not do
It does not say what any particular contract requires. The state pages on this site list the governing statute or program for each state and the roster entry where one is published. Where this edition has not read a state's roster, the state page says so, and this guide does not fill that gap.
