What a home warranty covers, and what the exclusions take back

Two lists, and only one of them decides a claim

A home service contract is built from a grant and a subtraction. The grant is the covered-item list: the systems and appliances the provider agrees to repair or replace. The subtraction is the exclusion list: the components, causes, locations, circumstances and costs removed from that grant. Buyers read the first list, because it is the one used to sell the product. Adjusters work from the second.

Understand the relationship and the whole document becomes legible. The covered-item list establishes what could be covered. The exclusion list establishes what is. A contract can name "air conditioning" in bold on page one and still decline a condenser failure because the system was mismatched, because the condition was detectable before the effective date, because the coils were not maintained, or because the work required is a code upgrade rather than a mechanical repair. None of that contradicts the grant.

Before either list: the item has to have suffered a "Breakdown"

There is a gate before the covered-item list is reached: coverage attaches to a defined event, not to a broken thing. One national provider's published sample defines a Breakdown as "the electrical or mechanical failure of the Covered Item to operate as designed when installed and used in accordance with the applicable manufacturer's instructions."

Three tests sit inside that definition, and a claim has to clear all of them:

• Electrical or mechanical failure. A crack, a stain, an obstruction, a jam or a worn consumable is not necessarily an electrical or mechanical failure.
• Failure to operate as designed. An undersized system that cannot cool the house it was installed in is operating exactly as designed. So is an old appliance that works badly but works.
• Installed and used per the manufacturer. Improper installation by a previous owner is a defence the current owner inherits along with the house.

The same logic produces the cosmetic exclusion. One published contract states the provider "will not repair cosmetic defects or damage to Covered Items that does not also cause a Covered Breakdown." A dented door panel on a covered appliance is not a Breakdown; the failed door latch behind it might be.

The standard covered categories, and the exclusions that decide each one

Covered-item lists differ in wording between providers, between coverage tiers, and between the direct-to-consumer and real estate editions of the same provider's contract, but they cluster into a stable set of categories, each of which this site treats as its own reference page. The table below pairs each category with the exclusion pattern that most often decides a contested claim in it, and with the way caps behave. It maps where the friction is; it does not substitute for the contract in front of you.

Note what the right-hand columns have in common. Very little of the contested territory is about whether an item appears on the covered list; it is about cause, location, condition at the effective date, and the cost of reaching the failure.

The exclusion categories that override everything above

A handful of exclusions do most of the work, and they apply across the covered-item list rather than to any one entry. A single failed condenser can be declined on four of them at once; a denial letter reciting all four is a file built to survive an appeal.

1. Pre-existing conditions. The exclusion that decides most contested claims. Some contracts exclude "known or unknown pre-existing conditions" outright. The more common formulation covers an unknown failure only where it "could not have been detected by visual inspection or simple mechanical test" — an objective standard, not a subjective one.
2. Lack of maintenance. Proved by demanding multi-year service records, with their absence treated as evidence of absence. The New Jersey Attorney General alleged in 2015 that one provider denied claims where consumers lacked multiple years of maintenance records.
3. Improper installation, modification, undersizing or mismatch. Inherited from previous owners, and rarely visible to a buyer.
4. Code violations, permits and upgrades. The contract pays to restore function, not to bring an installation up to current code.
5. Not a Breakdown. Cosmetic damage, obstructions, jams, consumables, and items that operate as designed.
6. Item, component or location not covered. The category is covered; the specific part, or the specific run of pipe, is not.
7. Another warranty is primary. Manufacturer, builder, distributor or extended warranty coverage suspends the service contract's obligation.
8. Secondary and consequential damage. The failure is covered; the damage it caused is not. Florida's statute treats indemnification against consequential damages as the transaction of insurance, which is precisely why service contracts do not offer it.
9. Adjacent costs. Permits, code upgrades, haul-away and disposal, crane or lift access, refrigerant line sets, and modifications needed to fit new equipment. These turn a covered claim into a partially covered invoice.

Caps: the third list, and usually the binding one

Coverage can be complete and still be worth very little, because limits operate at three levels simultaneously.

• Per covered item. One published user agreement sets maximum liability at a low four-figure amount per twelve-month period for each covered item, with sublimits in the hundreds on items such as well pump, roof leak and septic.
• Contract-wide aggregate. Published samples show aggregate ceilings ranging from the mid five figures down to figures an order of magnitude smaller, depending on the provider and the edition.
• Category and rider sublimits. These are what actually bind. One published sample caps air conditioning and geothermal, pool and spa heaters, outside gas lines and outside sewer lines at separate and much lower amounts. A category cap in the low four figures does not replace a condenser, and that gap is what most complaints are really about.

Two structural points sit behind the numbers. Caps are almost always aggregate per item per contract term, not per occurrence — two failures of the same item in one year share one limit. And in a resale transaction, seller or listing-period coverage frequently carries its own low ceiling for all claims during the listing period, superseding the individual item limits the seller believes they have. Every figure in a published sample is state-specific, tier-specific and dated; treat them as evidence of structure rather than as quotations.

Riders: coverage sold separately, capped separately, and sometimes waited separately

The items homeowners most want covered are frequently the ones sold as optional add-ons: pool and spa equipment, well pump, septic system, sewer line, second refrigerator, guest unit, roof leak. Moving up a coverage tier is a related but distinct decision — it usually raises per-item limits as much as it adds items, which is the part buyers overlook when comparing tiers on the covered-item list alone.

Three things about riders deserve attention before purchase. Each typically carries its own low aggregate cap, often low enough that the rider cannot fund replacement of the equipment it names. Each may carry its own waiting period, even when added mid-term to a base plan already in force. And each brings conditions of coverage — distance limits, access requirements, cleanout conditions — that live in the exclusion section rather than in the rider's description.

The gray areas: what buyers assume is covered and usually is not

A second family of items is not merely capped or conditioned but sits largely outside the product. These generate the sharpest disagreements at claim time, because they cost the most and a new owner is least prepared for them.

Structure and envelope. The roof as a system, the foundation, windows, gutters and siding. A service contract addresses mechanical and electrical failure of systems and appliances; a wall assembly does not fail electrically or mechanically. Where roof coverage exists it is normally a narrow rider for repairing an active leak over living space, with a low sublimit and express exclusion of the roof itself.

Environmental and biological conditions. Mould, termites and other wood-destroying insects, general pest activity, asbestos and lead paint. These are conditions rather than component failures, they are governed by separate disclosure and inspection regimes, and they are commonly excluded by name. Where a contract touches pest work at all it may do so as a discrete service with its own per-contract fee, as in one published contract's separate termite treatment charge.

Consequences of a covered failure. Water damage from a covered plumbing failure, and slab-leak access and restoration, are the clearest examples. The pipe is covered; the flooring, drywall and contents are not, and the concrete opened to reach the pipe frequently is not either. State regulators draw the same line in consumer messaging: the Texas Department of Insurance explains that insurance pays for damage from covered events but not wear and tear, while warranties cover items that break down from normal wear and tear.

Newer equipment classes. Solar arrays and their inverters sit in a different warranty ecosystem — manufacturer and installer warranties, often long-tail — and service contracts generally exclude what another warranty covers.

This site treats each of these as a page of its own, in the same format as the covered categories, precisely because "not covered" is a conclusion that needs its reasoning shown.

How to read a contract in the order that matters

The covered-item list is the least informative part of the document and the first part everyone reads. A more useful sequence is the reverse of the marketing order.

1. The caps and limits table first. If the category sublimit is far below the replacement cost of the equipment, the rest of the analysis is academic. Nominal coverage is knowable before purchase.
2. The exclusions second. Read the pre-existing condition clause and the maintenance clause word for word, and note whether the contract excludes all pre-existing conditions or only those that were known or reasonably detectable.
3. The definitions third. "Breakdown," "Covered Item," "Covered Item Limit" and the geographic boundary language do more work than any other text in the contract.
4. The claims and dispute sections fourth. Who authorises work, what happens to unauthorised repairs, and whether disputes go to arbitration.
5. The covered-item list last, read against everything above rather than on its own.

The sample contract for the state and edition being sold is normally obtainable before payment. The best single predictor of satisfaction with this product is whether the buyer read the covered-item list, the caps table and the exclusions before paying rather than after a denial.

The window in which any of this is still actionable

Coverage questions have a shelf life. During the inspection or option period, a defect found in the report can still be repaired by the seller, priced into the deal, or walked away from — remedies worth far more than a capped claim later. Once that period closes, the same defect becomes a documented, detectable, pre-existing condition, and the contract's most-used exclusion is waiting for it.

The other windows run in parallel. Coverage bought directly commonly attaches thirty days after payment. Where a seller's listing coverage converts to buyer coverage at closing, the conversion has its own deadline measured in business days. Riders added later can start a waiting period of their own. And the renewal contract, not the one reviewed at closing, governs the following term.

None of this is legal or insurance advice. It is the reason the sequence matters: the covered-item list is fixed the day you pay, and everything a buyer can still do about the exclusions has to happen before that.
