How home warranties work in the US

A home warranty covers repair or replacement of a home's major systems and appliances when they break down from ordinary wear — not damage, and not something that was already broken. It is legally a service contract, and whether that means it's regulated like an insurance product or something else entirely depends entirely on which state you're in.

It's a service contract, not insurance — but states don't agree on which category it belongs to

The FTC's own consumer guidance draws a hard line between a manufacturer's warranty (comes with the product, backed by the manufacturer) and an "extended warranty" or service contract (bought separately, backed by whoever sold it to you). A home warranty is that second thing. But US states split on how to regulate it: some, like California and Florida, put it inside the insurance code — California licenses "Home Protection Companies" under Insurance Code §§ 12740–12764, and Florida licenses "home warranty associations" under Florida Statutes chapter 634, Part II, both through the state's insurance regulator. Others, like Texas, regulate it as a distinct category outside the insurance code — Texas licenses home warranty companies (as "residential service contract" providers) under Occupations Code Chapter 1304, with oversight moved from the Texas Real Estate Commission to the Texas Department of Licensing and Regulation effective September 1, 2021; see our Texas deep-dive for how that chapter actually works. Many other states fall somewhere between these two models or regulate more lightly — this genuinely varies, and it's worth checking your own state's specific rule rather than assuming either pattern applies nationwide.

How coverage actually works

You pay an annual or monthly contract fee, plus a separate service-call fee (commonly $75–$125) each time you file a claim and a technician is dispatched. Most contracts impose a waiting period — commonly 15 to 30 days — between enrollment and the point coverage actually begins, specifically to discourage buying a plan the moment something starts failing. Coverage is typically split into a base plan (major systems like HVAC, plumbing, electrical) and an appliance add-on (refrigerator, washer/dryer, etc.), each with its own list of what's covered, what's excluded, and a dollar cap per claim or per contract year.

The single most common reason claims get denied

Every home warranty contract excludes "pre-existing conditions" — a system or appliance that was already failing, or not properly installed or maintained, before or at enrollment. In practice, this is also the single most common source of complaints in the industry: a homeowner files a claim, a contractor's inspection notes something like "signs of prior wear," and the claim is denied on that basis — sometimes without the provider having inspected the item at enrollment to establish a baseline at all. A second, related exclusion covers damage attributed to lack of maintenance (an HVAC system that failed because filters were never changed, for example). Neither exclusion is inherently improper — real pre-existing conditions and real neglect both exist — but reading exactly how a specific contract defines and applies both exclusions before signing is the highest-value five minutes you can spend on this product.
