When you compare home warranty contracts, the plan name tells you less than you might expect. Two contracts with the same name can carry different charges, and one factor many homeowners overlook is the age of the house and of the equipment the contract would cover.

Why age shapes the price

Older equipment tends to need repair more often. A company that agrees to take on that risk usually reflects it somewhere in the contract, either in what it charges, in which items it agrees to cover, or in how it treats items that were already worn when you signed. Some contracts set an age limit for each covered item. Others ask for an inspection before certain items join the contract, and some leave older items out entirely. The written terms, not the sales call, tell you which approach applies.

Four terms that move the total

The service call fee is the charge you pay each time a technician visits to look at a covered item. An older dishwasher that needs several visits in a year makes that charge repeat, so a low fee and a high fee can add up quickly.

The annual cap is the most the contract will pay toward covered repairs in one contract year. Older equipment that fails often may reach that ceiling sooner, which leaves less room for the rest of the house.

The waiting period is the stretch after signing when covered repairs are not yet available. Contracts often use it to screen out problems that already exist, and older equipment is more likely to have one.

Finally, many contracts treat a replaced item differently from the original. Read how the contract handles a replacement before you assume the new unit is covered on the same terms.

What to check before you compare

Ask the company, and find the answer in the written terms, whether the contract sets an age limit per item or per home. Ask whether an inspection is required, who pays for it, and what happens if the inspection finds a problem. Ask whether a pre-existing condition clause applies to older units. Ask whether the service call fee is the same for every covered item. Ask what happens to a covered item that is replaced during the contract.

Keep your answers in writing. If you want the published figures for a set of companies side by side, the twelve home warranty companies compared, term by term page lays them out in one place.
