A service plan is a contract, and it often matters more than the price on the first page. Many owners sign one at install, then forget it until a renewal notice arrives. This guide shows what to read in the paperwork before you sign, and what to check while the plan runs.

What the plan actually includes

Read the list of covered work line by line. Look for whether it includes filters or cartridges, lamps or media, labour, travel charges, and a pressure or water test. Note what is excluded. A plan that covers the visit but not the parts, or the parts but not the labour, can cost more than its headline suggests. Ask the seller to point to each covered item in the document rather than describing it from memory.

Renewal and price changes

Find the renewal clause and the price change clause. Note whether the plan renews automatically, how long the notice period is before renewal, and whether the seller can change the price at renewal and with how much warning. A plan that renews without a clear reminder can run past the point you intended to keep it.

How to cancel

Find the cancellation section and write down three things: how you must cancel (in writing, to a particular address, or on a form), how far ahead you must do it, and whether any part of the fee is refunded if you stop partway through a term. Some plans allow cancellation only at renewal. Ask the seller to describe the steps in writing before you sign, so you are not relying on a phone conversation later.

Who holds the contract

Check whether the plan is with the installer, the equipment maker, or a third party that resells the service. That matters if the installer closes, moves away, or stops answering. Find out who performs the work, who you call first when something fails, and whether the company name on the plan matches the company on your install invoice.

Transfer if you sell the house

If you might sell, ask whether the plan transfers to the new owner, whether a fee applies, and whether the buyer must sign anything. A plan that cannot transfer may be a cost you cannot recover at closing, so read this clause before you pay for a long term up front.

A plan is not a warranty

A service plan and a warranty are separate papers, and they can have different exclusions and different claim steps. Read the warranty for what it voids, and read the plan for what it covers. Do not assume one covers what the other leaves out, and ask the seller to show you where each one stops.
