What does a home warranty cover?
A home warranty pays to repair or replace major home systems and appliances that break down from normal wear and tear. Systems coverage typically includes heating, air conditioning, ductwork, plumbing, electrical and the water heater; appliance coverage typically includes the refrigerator, oven or range, cooktop, dishwasher, built-in microwave, washer, dryer and garbage disposal. Every covered item has a dollar cap, and add-ons can extend coverage to pools, well pumps, septic systems and roof leaks. Known pre-existing problems, improper installation, missing maintenance, cosmetic damage and structural parts of the home are generally excluded. Our recommendation: Liberty Home Guard, our top-rated provider, which covers both groups in its Total Home Guard plan and offers 40+ add-ons.
- Systems plans cover HVAC, ductwork, plumbing, electrical and the water heater; appliance plans cover kitchen and laundry appliances; combo plans cover both.
- Coverage applies to mechanical failure from normal wear, not to accidents, storms or neglect.
- Every item has a cap, and caps differ by item: $500 to unlimited among the providers we compare.
- The most common denials come from pre-existing conditions, waiting periods, missing maintenance and excluded parts.
- Read the sample contract's coverage, exclusions and limits sections before you buy; it takes about 10 minutes.
- Our top-rated provider, Liberty Home Guard, combines systems and appliances in Total Home Guard and offers 40+ add-ons.
What Is Typically Covered by a Home Warranty?
Home warranties cover the working parts of major systems and appliances when they fail from age and normal use. Most providers sell three plan types, and the combo plan is the most complete.
| Plan type | Typically covers | Best for |
|---|---|---|
| Systems | Heating, air conditioning, ductwork, plumbing (including stoppages), electrical, water heater | Homes with HVAC or water heaters 8+ years old |
| Appliances | Refrigerator, oven/range, cooktop, dishwasher, built-in microwave, washer, dryer, garbage disposal | Newer systems but aging appliances |
| Combo | Everything above | Most resale homes and rentals |
As an example of a real lineup, Liberty Home Guard's Appliance Guard covers the refrigerator, oven/range, cooktop, dishwasher, built-in microwave, washer, dryer, garbage disposal, ceiling and exhaust fans and garage door opener. Its Systems Guard covers air conditioning and heating up to 5 tons, ductwork, plumbing including stoppages, electrical and water heaters up to 75 gallons. Total Home Guard combines both.
What Does "Covered" Mean for Each Home System?
"Covered" usually means the functional components that make the system run, not every part attached to it. The table shows how contracts commonly draw the line.
| System | Usually covered | Often excluded or limited |
|---|---|---|
| Heating & air conditioning | Compressor, condenser, coils, blower and fan motors, thermostat, igniters, control boards | Window units, geothermal or solar systems, refrigerant line replacement, units over the size limit |
| Ductwork | Duct runs from the unit to the registers | Registers and grills, insulation, ducts in concrete or inaccessible areas |
| Plumbing | Leaks and breaks in supply and drain lines, valves, stoppages that can be cleared through an existing access point | Lines outside the foundation, fixtures and faucet finishes, slab leaks in some plans, sewer lines unless added |
| Electrical | Panels, breakers, wiring, outlets, switches | Low-voltage and solar systems, fixtures, code upgrades |
| Water heater | Tank or tankless unit components, thermostats, elements, gas valve | Solar water heaters, venting, sediment-related failures if not maintained |
Common contract patterns; your contract's exact wording controls.
How Does Appliance Coverage Work, Part by Part?
Appliance coverage focuses on the parts that make the appliance function: motors, pumps, compressors, controls and heating elements. Parts that are cosmetic, removable or easy to break by hand are usually excluded.
| Appliance | Parts usually covered | Parts usually excluded |
|---|---|---|
| Refrigerator | Compressor, sealed system, thermostat, fan motors; ice maker in some plans | Shelves, bins, door handles, food spoilage, water filters |
| Dishwasher | Pump, motor, timer, control board, door latch | Racks, baskets, rollers, cosmetic panels |
| Oven, range, cooktop | Heating elements, burners, igniters, controls | Glass doors and cooktop glass in some plans, clocks, knobs, racks |
| Washer and dryer | Motor, pump, timer, belts, heating element | Lint screens, dials, knobs, damage from overloading |
| Garbage disposal | The full unit | Jams caused by foreign objects |
How Do Coverage Caps Work?
A coverage cap is the most the provider will pay for a covered repair or replacement. Caps can apply per item, per system, per claim or per contract term, and anything above the cap is your cost.
| Company | Coverage caps | Waiting period | Add-ons |
|---|---|---|---|
| Liberty Home Guard | $2,000 per item for most systems & appliances | 30 days (90 days for plumbing/electrical) | 40+ optional add-ons |
| Choice Home Warranty | $3,000 per item | Typically 30 days | 6 add-ons (pool/spa, well pump, septic, roof leak and more) |
| Cinch Home Services | A/C & heating $1,500; plumbing $1,000; appliances $2,000; $10,000 per term | Typically 30 days | Limited |
| First American Home Warranty | Unlimited on HVAC, plumbing & electrical; appliances $3,500-$7,000 | Typically 30 days | Pools, septic and more |
| 2-10 Home Buyers Warranty | ~$2,000 per category ($5,000 with Luxury Package); $25,000 per 12 months | Typically 30 days | Pools, septic, well pump, roof leak |
Published terms from company pages and third-party reviews, checked October 14, 2026.
Your furnace control board and blower motor fail together, and the repair is quoted at $2,600. With a $2,000 per-item cap, the provider pays $2,000 and you pay the remaining $600 plus your service fee. With a $1,500 cap, you would pay $1,100 plus the fee.
Also watch for term-wide limits. Cinch caps total payouts at $10,000 per term, and 2-10 at $25,000 per 12 months, on top of their per-item limits.
What Doesn't a Home Warranty Cover?
Home warranties exclude anything that is not a normal-wear breakdown, along with structural parts of the home and damage from outside events. These are the common exclusions.
- Known pre-existing conditions (problems that existed before coverage began)
- Failures during the waiting period after you sign up
- Improper installation, prior bad repairs or code violations
- Damage from missing routine maintenance (for example, never changing HVAC filters)
- Cosmetic issues such as dents, scratches and finish wear
- Structural elements: foundation, walls, the roof structure, windows and doors
- Sudden damage from fire, flood, storms or theft, which belongs to homeowners insurance
- Mold, pests and resulting water damage to floors, walls or belongings
How Do Home Warranties Handle Pre-Existing Conditions?
Most contracts exclude problems that existed before your coverage started, whether or not the provider could detect them at enrollment. A few providers soften this rule for issues you could not have known about.
Contracts typically define a pre-existing condition as a defect or malfunction that existed before the coverage start date, or before the end of the waiting period. Technicians look for signs such as long-term corrosion, prior patch repairs or a system that was already running poorly.
- Cinch covers unknown pre-existing conditions, which is helpful if you just bought a resale home.
- Liberty Home Guard does not require a home inspection to enroll; its standard waiting period is 30 days, or 90 days for plumbing and electrical, with a reduced cap during that window.
- Home buyers can lower their risk by keeping the inspection report, which documents what worked on the day of the sale.
What Optional Add-Ons Can You Buy?
Add-ons extend coverage to items base plans leave out. They are priced individually, so you only pay for what your home has.
- Pool and spa equipment
- Well pump and septic system
- Roof leak repair (repairs to leaks, not roof replacement)
- Second refrigerator and stand-alone freezer
- Sump pump and water softener
- Generators, professional-grade appliances and pest control (Liberty Home Guard)
Liberty Home Guard offers 40+ add-ons, the largest catalog among the providers we compare. Choice lists 6 add-ons, and Cinch's add-on menu is limited.
Five Example Claims: Covered or Denied?
Whether a claim is approved depends on the cause of the failure, the timing and the part involved. These five illustrative scenarios show how typical contract language applies.
| Illustrative claim | Likely outcome | Why |
|---|---|---|
| 13-year-old AC compressor fails in July; filters changed regularly | Covered up to the cap | Normal wear on a covered component; you pay the service fee plus any amount over the cap |
| Water heater tank rusts through 4 months after enrollment and floods the basement | Heater covered; water damage not covered | The tank is a covered system; the damaged drywall and flooring are a homeowners insurance question |
| Dishwasher rack rollers break | Denied | Racks and rollers are typically excluded parts |
| Furnace stops working 12 days after the plan starts | Denied | Failure occurred during the waiting period |
| Breaker panel fails and the repair requires a code upgrade | Repair covered; code upgrade likely not | Code upgrades are often excluded unless the plan includes them |
Illustrative examples only. Actual decisions depend on your contract, the technician's diagnosis and the provider's review.
How Do Providers Differ on Coverage?
The biggest differences between providers are caps, availability, add-on depth and special terms like pre-existing condition coverage. Plan names sound similar, but the details change what you actually get.
| Company | Coverage strength | Coverage trade-off |
|---|---|---|
| Liberty Home Guard | 40+ add-ons, all 50 states + DC, $2,000 cap on most items | $500 cap on plumbing and electrical; 90-day wait on those |
| Choice | $3,000 per-item cap | Air conditioning, refrigerator, washer and dryer only in the Total Plan; not in CA or WA |
| Cinch | Unknown pre-existing conditions, rust and corrosion | $1,500 A/C and heating cap; no roof coverage option |
| First American | Unlimited HVAC, plumbing and electrical caps | Starter plan excludes AC, washer and dryer; 36 states |
| 2-10 | Higher limits with Luxury Package | $25,000 annual aggregate cap |
How Can You Read a Sample Contract in 10 Minutes?
You don't need to read every word. Jump to five sections in this order, and you'll know almost everything that decides your claims.
- Covered items (2 minutes). Confirm every system and appliance in your home is listed, including size limits such as AC tonnage or water heater gallons.
- Limits of liability (2 minutes). Write down the cap for each item you care about and any per-term limit.
- Exclusions (3 minutes). Look for pre-existing condition wording, code upgrades, access costs, and parts excluded by name.
- Waiting period and start date (1 minute). Note when coverage begins for each category.
- Service fee and cancellation (2 minutes). Check whether the fee applies per visit or per claim, and what refund you get if you cancel.
What About Coverage for Older Homes?
Older homes can be covered, and they often get the most use out of a plan, but exclusions bite harder. Code upgrades, prior repairs and corrosion are more common in homes over 20 years old.
- Choose a provider that covers unknown pre-existing conditions or rust and corrosion if your systems are original.
- Look for plans that include code upgrades, or budget for them separately.
- Schedule an HVAC tune-up and keep the invoice before your coverage starts.
If you want one plan you can tailor to an older or larger home, Liberty Home Guard's Total Home Guard covers systems and appliances with 40+ optional add-ons and is available in all 50 states. Read our Liberty Home Guard review.
Which Questions Should You Ask Before Buying?
A short list of questions, asked before you pay, prevents most coverage surprises. Get the answers in writing or find them in the sample contract.
- What is the cap on my HVAC, water heater and refrigerator? These are the costliest common failures.
- How do you define a pre-existing condition? Ask whether unknown issues are covered.
- Are code upgrades, permits and haul-away included? These often decide your out-of-pocket cost.
- How long is the waiting period for each category? Some are longer for plumbing and electrical.
- What is the workmanship guarantee? Liberty Home Guard offers 60 days, Cinch 180 days and First American 30 days.

Frequently asked questions
Does a home warranty cover the roof?
Base plans do not cover the roof structure. Some providers sell a roof leak add-on that pays to repair leaks up to a limit.
Does a home warranty cover mold?
Generally no. Mold remediation is a standard exclusion.
Does a home warranty cover pre-existing conditions?
Most plans exclude them. Cinch is an exception for unknown pre-existing conditions.
Does a home warranty cover water damage?
It covers the failed pipe or appliance, not the resulting damage to floors, walls or belongings. That damage is usually a homeowners insurance matter.
Does a home warranty cover TVs and electronics?
Not in base plans. Some providers offer add-ons for items beyond standard appliances.
Can I choose my own technician?
Usually not. The provider assigns a contractor from its network, though some allow outside contractors with prior approval.
