A full, item-by-item breakdown of what home warranties typically cover — systems, appliances, and add-ons — plus the pattern that determines what’s excluded across every category.

---

A home warranty covers the repair or replacement of a home’s major systems and appliances when they fail from normal wear and tear — but “what does it cover” has a different, more specific answer depending on which item you’re asking about, which plan tier you’ve purchased, and which provider you’re comparing. This guide brings all of that together in one place: a full checklist of what’s typically included, what’s typically excluded, and the single underlying pattern that explains almost every coverage decision across the entire industry.

The Two-Bucket Framework

Nearly every home warranty plan is built around two coverage categories, and understanding this split is the fastest way to predict what your specific plan actually includes:

• Systems — HVAC, plumbing, electrical, water heater, and ductwork. These are almost always included, even on a provider’s most basic, entry-level plan tier.
• Appliances — refrigerator, oven/range, dishwasher, garbage disposal, washer, and dryer. These are frequently reserved for a mid-tier or combination plan, and excluded entirely from a “systems-only” base plan.

A number of providers in this comparison series illustrate the split clearly: American Home Shield’s entry-tier ShieldSilver excludes all appliances; Choice Home Warranty’s Basic Plan covers most kitchen appliances but excludes air conditioning and refrigerators specifically; Select Home Warranty separates its plans by category entirely, with Gold Care covering systems and Silver Care covering appliances. If you’re comparing plans, the first question to ask isn’t “does this company cover X” — it’s “which specific plan tier includes X.”

Full Coverage Checklist

Core Systems (Included on Nearly Every Plan, Including Entry-Level Tiers)

System	Typically Covered	Common Exclusions

Air conditioning / HVAC	Often, sometimes a higher tier	Freon leaks, code upgrades
Electrical wiring & panel	Yes	Code violations, surge damage to electronics, solar systems
Plumbing (leaks)	Yes	Slab leaks, sewer lines, stoppages (sometimes higher tier only)
Water heater	Yes	Sediment damage, capacity upgrades
Ductwork	Often	Varies by provider

Appliances (Often Reserved for a Mid-Tier or Combination Plan)

Appliance	Typically Covered	Common Exclusions
Refrigerator	On appliance-inclusive plans	Food spoilage, built-in/premium models may have separate caps
Oven / range / cooktop	On appliance-inclusive plans	Cosmetic damage
Dishwasher	On appliance-inclusive plans	Pre-existing leaks
Garbage disposal	On appliance-inclusive plans	Misuse/foreign objects
Washer & dryer	Often a higher tier	Venting issues, resulting water damage
Garage door opener	Varies by tier, but usually included relatively early	The door itself — springs, tracks, cables

Specialty Items (Almost Always a Paid Add-On, Rarely Standard)

Item	Standard Inclusion?	Notes
Roof leaks	Rarely standard; sometimes a top-tier perk	Patch/repair only — never full roof replacement
Pool & spa equipment	No — always an add-on	Equipment only, not the pool structure
Septic systems	No — always an add-on	Value depends heavily on conventional vs. aerobic system type
Well pump	No — usually bundled with septic in rural packages	Separate coverage from septic itself
Sump pump	No — usually a separate add-on	Basement flood prevention, distinct system

The One Pattern That Explains Almost Every Exclusion

If you’ve read any of our individual coverage guides, you’ve probably noticed the same underlying logic repeating across completely different categories: home warranties cover the mechanical component that does the work, not the structural asset that component serves.

• HVAC: the compressor and furnace are covered; ductwork condition and code compliance issues are not always
• Plumbing: pipe leaks are covered; the resulting water damage to your floor is not (that’s homeowners insurance)
• Garage doors: the opener motor is covered; the springs, tracks, and door panels are not
• Roofs: patching an active leak may be covered; full replacement never is
• Pools: the pump and heater are covered; the pool shell and structure are not
• Septic: the pump and control panel (if present) are covered; the tank and drain field are not

Once you recognize this pattern, you can reasonably predict how a provider will likely treat almost any coverage question you have — even for an item that doesn’t have its own dedicated guide on this site.

What Determines Whether Something Is Actually Covered

Beyond the systems-vs-appliances split, three additional factors determine your real-world coverage:

1. Your specific plan tier. As covered above, many items that sound like they “should” be included are actually reserved for a mid- or top-tier plan.
2. The item’s condition at enrollment. Nearly every provider excludes pre-existing conditions — anything already malfunctioning before your coverage began. This is why some providers require (or strongly encourage) a home inspection before or shortly after enrollment.
3. Maintenance history. For systems like HVAC and septic in particular, providers can deny a claim tied to a documented lack of routine maintenance. Keeping basic service records is one of the simplest ways to protect your claim history across every category.

Coverage Caps: The Detail That Matters More Than the Checklist

Knowing that something is “covered” only answers half the question — the other half is how much the provider will actually pay before you’re responsible for the rest. This varies dramatically by provider and category:

• HVAC caps range from $1,500 (Cinch Home Services) to $6,500+ (Old Republic Home Protection), against a typical $4,500–$8,000 full replacement cost
• Appliance caps range from $500 (Select Home Warranty) to $7,000/item (Old Republic Elite, First American Premium)
• Specialty add-ons like pool/spa and roof leak coverage typically carry their own, separate (and usually lower) caps

Frequently Asked Questions

Does a home warranty cover everything in my house? No. Coverage is limited to specific systems and appliances listed in your contract, generally split between “systems” (HVAC, plumbing, electrical, water heater) and “appliances” (refrigerator, oven, dishwasher, laundry), with structural elements, cosmetic issues, and pre-existing conditions excluded across virtually every category.

Is a basic home warranty plan enough, or do I need a higher tier? It depends on what you want covered. Basic/systems-only plans typically exclude appliances entirely — if you want your refrigerator, washer, dryer, or AC covered, you’ll generally need a mid-tier or combination plan.

What’s the most commonly misunderstood exclusion across home warranty plans? The distinction between a covered mechanical component and an excluded structural element — for example, a garage door opener motor is covered, but the springs that actually cause most garage door failures are not; a water heater failure is covered, but water damage it causes to your floor typically isn’t.

Does a home warranty cover pre-existing problems? No. Providers require covered items to be in working condition at the time you enroll, and pre-existing issues are excluded across virtually every provider and category.

How do I know exactly what my specific plan covers? Your provider’s contract (sometimes called a service agreement) lists every covered item explicitly, along with its specific coverage cap. Since terms vary meaningfully by provider and plan tier, always review your actual contract rather than relying on general industry patterns alone.
