You have had the conversation. The representative was friendly, the explanation made sense, and someone described how the system would be looked after in a way that sounded reassuring. Before you sign anything, find out whether any of that is in the paper.
Find the Entire Agreement Line
Most service contracts and warranties include a line that says the written document is the whole agreement. Look for it near the end, usually in a section of general terms. It means that statements made before signing, whether spoken, printed in a brochure, or posted on a website, are not part of the deal unless they also appear in the written contract. Read the line once and understand what it does. It sets the boundary for every other point on the table.
This is not a sign that anyone is being dishonest. It is a standard way to keep the record clear. Your job is to make sure the record includes what you actually relied on.
List What You Were Told
Before you sign, write down every statement that shaped your decision. Note who said it, when it was said, and the wording as close as you can recall. Typical examples include how visits are scheduled, how quickly a request is answered, which parts are named, what happens on a transfer to a new owner, and how the paper treats an older unit.
Then find each statement in the contract. If a point is missing, ask for it to be added in writing as a signed addendum. If the company will not put it in writing, treat the statement as if it was never made. A written addendum does not settle how a future claim will be decided, but it does make the terms easier to check later.
Compare the Summary to the Contract
Brochures, website pages, and quote sheets usually simplify the contract. Set each simplified statement next to the language it describes. Where the two differ, the contract is the document that governs. Ask which version you based your decision on, and ask for any gap between them to be explained in writing.
Questions to Ask Before You Sign
- Which document is the final contract, and will I receive a complete signed copy?
- Which of the things I was told during the sale appear in the written paper?
- Can any missing point be added as a signed addendum before I sign?
- Who do I contact to request a visit or a repair, and how is that request recorded?
- Does the paper say who approves a claim, and what happens if the approval is delayed?
- What does the paper say about changes to the terms, and how will I be told of them?
Keep the Signed Copy With the Equipment Record
Put the signed contract, any addendum, and your list of what you were told in the same folder as the equipment's install record. When a visit is requested, read the folder first. The paper tells you what was agreed. The install record tells you the age the planning is built on. You need both on hand.
