What Is a Home Warranty and What Does It Cover?

A home warranty is a service contract that covers the repair or replacement of major systems and appliances, such as HVAC, water heaters, and kitchen appliances, for a set term after your purchase. Sellers often offer one as a concession to make a deal more attractive, and buyers can also purchase their own policy. In exchange for a service fee per claim, the warranty company sends a contractor to repair or replace covered items that fail from normal wear and tear.

It is a budget-protection tool for the first year of ownership, when surprise breakdowns are most common after a move.

Think of it as a bridge: it protects you during the period when you know the least about the home's systems. The inspection tells you what is visible today, and a warranty covers what fails in the coming months from ordinary use, which is precisely the window where new owners get hit with the most unexpected bills.

Most plans cover the systems and appliances that break from ordinary use, typically the heating and cooling system, electrical and plumbing systems, water heater, and major kitchen appliances. Coverage tiers add items like washers, dryers, and pool equipment.

Exclusions matter just as much. Common gaps include pre-existing conditions, improper installation, lack of maintenance, code violations, and items past their useful life. Every claim carries a service fee, often $75 to $150, similar to an insurance deductible, and policies cap what they will pay per item. Read the contract terms before you rely on it.

A practical note on the service fee: the company sends its own contractor, not one you choose, and the fee is due on every claim. If two appliances fail in one year, that is two fees. Knowing the fee schedule and the claim process before a breakdown happens makes the warranty far easier to use under pressure.

They cover completely different problems, and you need both. Homeowners insurance protects against sudden damage from events like fire, storms, and theft. A home warranty covers breakdowns from age and normal wear, like an air conditioner that dies in July. They are not substitutes; a warranty never covers storm damage, and insurance never covers a failing water heater.

Knowing the difference prevents the common mistake of filing an insurance claim (and risking a rate increase) for what is really a warranty-covered repair.

Sellers often include a one-year home warranty as a concession, covering the first year after closing. Buyers can also add a warranty themselves through the purchase contract or just after closing, paying the annual premium out of pocket. The right move depends on the home's age and condition.

A home that passed inspection cleanly still has aging systems, and a brand-new house may have builder warranties of its own, so there is no one-size-fits-all answer.

As a negotiation matter, a seller-offered warranty is a low-cost concession that can close a deal: it rarely costs the seller much, and it gives the buyer a concrete, visible form of protection. Buyers should treat it as a bonus, not a substitute for their own due diligence.
