What does a home warranty cover?
A home warranty is a service contract, not insurance. For an annual fee, the company agrees to repair or replace specific home systems and appliances when they break down from normal wear and tear — separate from your homeowners insurance, which covers sudden events like fire, theft, or storm damage.
When something covered fails, you call the warranty company, pay a service call fee, and a contractor from their network diagnoses and fixes the problem. The company — not you — decides whether an item gets repaired or replaced, and coverage is capped per item and per contract term.
Covered
- HVAC system
Heating and air conditioning units that fail from normal operational wear are typically covered for repair, subject to the plan's limits.
- Electrical system
Wiring, breaker panels, and switches that malfunction from age or normal use are generally covered.
- Plumbing system
Leaks, clogs, and pipe failures from normal wear are covered; the fixtures themselves may need an add-on.
- Water heater
Tank and tankless water heaters that fail from normal wear are standard coverage on most plans.
- Refrigerator
Kitchen refrigerators (not always a garage second unit) are covered on most appliance plans.
- Oven, range, and cooktop
Mechanical and electrical failures in built-in and freestanding units are typically covered.
- Washer and dryer
Usually an optional add-on rather than base coverage, but widely available.
- Dishwasher
Covered on standard appliance plans when the failure is mechanical, not cosmetic.
Not covered
- Structural components
Roofs, walls, foundations, and other structural elements are outside a home warranty's scope — that's a homeowners insurance or builder's warranty question.
- Pre-existing conditions
A system or appliance that was already failing, poorly maintained, or improperly installed before the contract started is excluded.
- Improper installation or prior repairs
Damage traced to code violations, mismatched sizing, or work done by an unlicensed contractor voids the claim.
- Lack of maintenance
Failures caused by skipped maintenance — like a water heater never flushed or HVAC filters never changed — are denied as neglect, not wear.
- Cosmetic damage
Scratches, dents, and discoloration that don't affect function are excluded even on a covered appliance.
- Items over the coverage cap
Every covered repair or replacement has a dollar cap in the contract; costs above it are the homeowner's responsibility.
- Known or unknown pre-contract defects
Most contracts include a waiting period (commonly around 30 days) before new coverage takes effect, during which failures aren't paid.
Bottom line
A home warranty pays off when something you'd otherwise have to repair out of pocket — an aging HVAC unit, a water heater on its last leg — fails from ordinary wear. It is not a substitute for homeowners insurance, it doesn't touch structural problems, and the company gets to decide repair versus replace and which contractor shows up. Read the contract's item-by-item caps and exclusions before assuming a given failure is covered — that's where most claim denials happen.
That's the general picture. Yours is written in your actual documents.
