The headline of a service contract tells you what it intends to cover. The exclusions section tells you what it will decline to pay for, and that list often decides more of the outcome than the promise does. Read it before you compare prices, then set a pair of offers beside each other.
Find every exclusion source
Exclusions do not always sit in one place. Look for headings such as exclusions, what is not covered, limitations, or conditions, and check any addendum, endorsement, or separate schedule that comes with the sale. Ask for the complete set of documents in writing. An offer that quotes only the summary has not given you the full list.
Read the wording that does the work
Watch for phrases such as wear and tear, normal use, maintenance, pre-existing, consequential damage, modification, commercial use, and unit kept outside. Each phrase can turn a covered repair into a denied one. Ask the seller what each phrase means in a real claim, and ask whether the decision is made by the seller, the administrator, or a third party.
Match the list to your unit
Take the last few repairs you know about and check whether each would fall under an exclusion. Check the unit's age, fuel type, location, and any change you have made to it against the list. A contract that excludes modified units or units kept in certain places may leave a common situation uncovered.
Ask the questions that settle it
Ask whether a covered part that fails because an excluded part failed is covered. Ask whether a denial comes with a written reason that cites the exclusion by its wording. Ask whether the exclusion list can change at renewal, and whether an exclusion added later applies to a unit already under contract.
Compare the two lists side by side
Put the exclusion lists in columns. Mark each item that appears in both, each item that appears in only one, and each item whose wording differs. A short list is not automatically a better one if its wording is broader. Keep the marked copy with the contract so the comparison can be checked later.
