📌 Key Takeaway: The two most common reasons home warranty claims get denied are pre-existing conditions and lack-of-maintenance exclusions. A covered appliance can still have a denied claim if the specific failure falls under an exclusion in the contract.

Typically Covered

  • HVAC systems (heating and cooling)
  • Plumbing systems
  • Electrical systems
  • Kitchen appliances (oven, dishwasher, refrigerator on some plans)
  • Water heaters

Exact coverage depends heavily on the specific plan tier — some cover only systems, some only appliances, and comprehensive plans cover both, still with exclusions layered in.

Common Exclusions

  • Pre-existing conditions — if a provider determines an issue began before the policy start date, coverage doesn't apply. This includes minor leaks that worsened over time or components already showing wear.
  • Improper installation — a system that wasn't installed to code or manufacturer spec.
  • Code violations — repairs required to bring something up to current building code aren't covered.
  • Cosmetic damage — appearance issues that don't affect function.
  • Structural components, roofs, and exterior elements — usually excluded unless you pay extra for a specific add-on (roof-leak coverage, for example, is a popular optional add-on that Select Home Warranty includes free).
  • Lack of maintenance — neglecting routine upkeep (like never changing HVAC filters) and then filing a claim when the system fails is one of the most frequently misunderstood exclusions.

Known vs. Unknown Pre-Existing Conditions

Providers generally distinguish between "known" pre-existing conditions (ones you were aware of and didn't disclose) and "unknown" ones (issues that existed but weren't detectable). Most providers deny both — but American Home Shield is a notable exception, explicitly covering undetectable pre-existing issues in its contracts.

How to Reduce the Chance of a Denied Claim

  • Read the actual coverage schedule and exclusions list before signing, not just the marketing summary.
  • File claims promptly — delaying can itself become grounds for denial.
  • Keep basic maintenance records (filter changes, servicing) in case a provider questions upkeep.
  • If buying a home, negotiate with the seller to address any known issues with covered systems before closing, rather than relying on warranty coverage for something already broken.

Component-Level Exclusions Within "Covered" Items

Even when a system or appliance is listed as covered, specific components within it are sometimes excluded — for example, a covered refrigerator's ice maker or water dispenser might be excluded unless you add specific coverage for it. If a failure traces back to one of these excluded components, the claim can be denied even though the appliance itself is nominally covered. Requesting a sample contract before signing, and reading the coverage schedule line by line, is the only reliable way to catch this.

Frequently Asked Questions

Are roofs ever covered?

Not by default on most plans — roof-leak repair is commonly sold as an optional add-on. Select Home Warranty is a notable exception, including it free on every plan.

What happens if my repair costs more than the coverage limit?

You're responsible for the difference. Every covered item has a specific payout cap in the contract — if the actual repair or replacement costs more, the provider only pays up to that limit.
