What Does a Home Warranty Cover? Complete Coverage Guide 2026

Types of Home Warranty Plans

Home warranty companies offer three main plan structures to fit different homeowner needs and budgets. Understanding these options helps you select coverage that matches your home's age and your financial priorities. For a deeper look at how each option fits different households, see our home warranty options guide.

Systems-Only Plans focus exclusively on the mechanical systems that keep your home running. These plans cover HVAC (heating and air conditioning), electrical systems, plumbing, and water heaters. They're ideal for newer homes with recently purchased appliances or rental properties where landlords want to protect major infrastructure without appliance coverage. Systems-only plans typically run about $47 to $55 per month in 2026, or roughly $560 to $660 annually, making them one of the more budget-friendly options.

Appliances-Only Plans provide coverage for household appliances without including home systems. These plans cover kitchen appliances like refrigerators, dishwashers, ovens, ranges, microwaves, and garbage disposals, plus laundry appliances including washers and dryers. This option works well for homeowners with newer HVAC and plumbing systems but older appliances approaching the end of their lifespan. Expect to pay around $55 to $65 per month, or roughly $660 to $780 annually, for appliance-only coverage. Our appliance coverage guide breaks down exactly which components are protected.

Combination Plans offer the most comprehensive protection by covering both systems and appliances in a single package. These plans include everything from both categories above, making them the most popular choice for homeowners seeking complete peace of mind. Combination plans average about $73 per month in 2026 based on NerdWallet's national analysis, with premium tiers reaching $100 or more per month for higher coverage limits and larger annual claim caps.

What's Typically Covered by Home Warranties

Understanding what a home warranty actually protects is essential before purchasing coverage. Most plans cover systems and appliances that break down from normal wear and tear.

HVAC Systems

Home warranties cover central heating and cooling systems including furnaces, heat pumps, air conditioning units, ductwork (when accessible), and thermostats. Coverage includes compressors, condensers, evaporator coils, blower motors, and other mechanical components that fail due to normal use. Most 2026 plans cap HVAC coverage between $1,500 and $6,500 per system, with premium tiers such as American Home Shield ShieldPlatinum sitting at $5,000 per system. Common HVAC repairs cost $3,000 to $8,000 without coverage, and our HVAC coverage guide explains how the 2025 EPA A2L refrigerant mandate is now driving many claims toward full system replacements in 2026.

Electrical Systems

Electrical coverage includes interior wiring, circuit breaker panels, switches, outlets, ground fault circuit interrupters (GFCIs), and ceiling fans. When your electrical system experiences mechanical failure, the warranty covers diagnostic fees and repairs. However, upgrades required to meet current building codes are not included, and code work is one of the most common gaps for older homes. Electrical problems can pose safety hazards and repair costs often exceed $500 to $2,000, making this coverage particularly important.

Plumbing Systems

Plumbing coverage extends to supply and drain lines, toilet tanks and bowls, faucets, sink and tub drains, pressure regulators, and water shut-off valves. The warranty addresses leaks, clogs in accessible lines, and mechanical failures of plumbing components throughout your home. Emergency plumbing repairs can cost $500 to $4,000 depending on the issue's severity and location, with plumbing caps in 2026 typically ranging from $500 to $3,000.

Water Heaters

Most plans cover conventional tank and tankless water heaters up to a specified capacity (typically 40 to 50 gallons). Coverage includes heating elements, thermostats, gas control valves, burners, and tanks. Some plans limit coverage to one water heater unless you pay for additional units. Water heater replacement costs range from $800 to $3,500, making this a valuable coverage component.

Kitchen Appliances

Standard coverage includes refrigerators (including ice makers and water dispensers), dishwashers, built-in ovens and cooktops, ranges, built-in microwaves, garbage disposals, and trash compactors. The warranty covers motors, control boards, heating elements, pumps, and other mechanical components. Replacement costs for a refrigerator alone can exceed $1,500 to $3,000. In 2026, appliance caps range from $2,000 on most plans up to $5,000 with Cinch and $7,000 on First American's Premium plan.

Laundry Appliances

Clothes washers and dryers are covered under most combination plans, though they may be optional add-ons in some plans. Coverage includes motors, belts, drums, timers, and control boards that fail from normal wear. A new washer and dryer set costs $800 to $2,500, making coverage cost-effective for older units.

Garage Door Openers

Many plans include garage door opener motors and mechanical components. However, the door itself, springs, tracks, and panels are usually excluded unless you purchase additional coverage. Garage door opener repairs typically cost $150 to $350, while full replacements run $200 to $500.

Common Add-On Coverages

Beyond standard coverage, most providers offer optional add-ons for items not included in base plans. These additions typically cost $2 to $25 monthly per item in 2026, allowing you to customize protection for your home's specific features. Liberty Home Guard leads the market with over 40 add-on options, while most major providers offer 8 to 12 optional riders. Our add-ons guide breaks down which options are worth the extra cost.

Pool and Spa Equipment

Pool and spa add-ons cover pumps, motors, heaters, timers, and control systems for pools and hot tubs. This excludes the pool structure, spa shell, liners, and cleaning equipment. Given that pool pump replacements cost $700 to $1,500 and heater repairs run $200 to $800, this add-on provides valuable protection for pool owners at around $18 per month with American Home Shield.

Septic Systems

Septic system coverage protects septic tanks, pumps, and related mechanical components. Many homeowners with septic systems find this add-on valuable given the $3,000 to $7,000 average cost of septic repairs and the $10,000 to $25,000 expense of complete system replacement. This is one of the most popular add-ons in rural areas.

Roof Leak Repairs

Roof leak repair add-ons cover repairs for roof leaks up to specific limits ($1,000 to $1,500 typically). Understanding the difference between warranties and insurance is important here. This doesn't replace roof coverage from homeowners insurance, but it does address minor leak repairs not caused by storms or disasters.

Electronics and Smart Home Devices

A growing number of 2026 providers now offer dedicated electronics protection plans. American Home Shield's Electronics Protection Plan runs about $14 per month, while Home Warranty Inc offers a Home Office tier at roughly $10 per month (computers, tablets, routers) and a Total Home tier around $20 per month that adds smart thermostats, doorbells, locks, and security cameras. Standard plans still cover the mechanical and electrical parts of built-in smart appliances, but not the app, firmware, or Wi-Fi features. Our smart home device coverage guide explains exactly where embedded coverage ends and add-ons begin.

Well Pumps

Well pump coverage protects homeowners with well water systems from expensive pump repairs and replacements, which can cost $500 to $3,000. Homes relying on well water should strongly consider this add-on as pump failures leave you without running water.

Sump Pumps

Sump pump coverage prevents basement flooding costs by covering pump failures. With replacement costs of $400 to $900 and potential water damage exceeding thousands of dollars, this add-on provides peace of mind for homes with basements.

What's NOT Covered by Home Warranties

Understanding exclusions is just as important as knowing what's covered to avoid claim denials and out-of-pocket expenses. Pre-existing conditions remain the number one reason for claim denials in 2026, and our home warranty exclusions guide covers every common denial category in depth.

Pre-Existing Conditions

Any problem that existed before your coverage began is excluded, even if you weren't aware of it. Home warranty companies may inspect your home or review home inspection reports to identify pre-existing issues. If you buy a home with an HVAC system that wasn't functioning properly at closing, that malfunction won't be covered. This is why timing matters when purchasing a policy.

Improper Maintenance

Coverage requires proper ongoing maintenance. Failure to change HVAC filters regularly, neglecting to flush water heaters, or allowing gutters to clog can void your coverage. Most contracts require you to maintain items according to manufacturer specifications. Keep maintenance records to protect yourself from claim denials based on alleged neglect.

Cosmetic Issues

Dents, scratches, rust spots, discoloration, and other aesthetic problems aren't covered unless they affect functionality. A refrigerator with a dented door remains uncovered, but a damaged door seal preventing proper closure would qualify for coverage. The key distinction is whether the issue impacts the item's operation.

Structural Problems

Home warranties explicitly exclude structural components including foundations, walls, floors, ceilings, windows, doors, and roofing materials. These items fall under homeowners insurance or require separate coverage. Any structural damage must be addressed through insurance claims or contractor repair services.

Code Violations and Upgrades

If repairs require bringing systems up to current building codes, you'll pay those upgrade costs. Our home warranty code upgrades guide explains why these are typically excluded and the few plans that offer small allowances. For example, if your old electrical panel needs replacement but current codes require a larger panel, you'll cover the difference. Similarly, if HVAC ductwork modifications need code compliance updates, those expenses aren't covered.

Secondary Damage

When a covered item fails, the warranty covers repairing that item but not consequential damage. A leaking dishwasher repair is covered, but warped flooring from the leak is not. Similarly, spoiled food from a failed refrigerator isn't reimbursed. This is where homeowners insurance may provide protection that warranties don't.

Outdoor Items

Sprinkler systems, outdoor kitchens, detached structures, and items beyond your home's foundation are typically excluded unless specifically added. This includes fences, decks, patios, and landscaping irrigation systems which require separate coverage or insurance protection.

Coverage Limits and How They Work

Home warranty plans impose per-item or per-system coverage limits that cap what the company will pay for repairs or replacements. Understanding these limits prevents surprise out-of-pocket expenses, and our coverage limits explained guide walks through how they interact with real 2026 repair costs.

Standard Limit Ranges

Most 2026 plans set coverage limits between $500 and $6,500 per covered item or system, with the biggest variation happening on HVAC. Standard HVAC limits generally range from $1,500 to $6,500, appliances typically range from $500 to $1,500 on basic plans and up to $4,000 to $7,000 on premium tiers, and smaller items like garage door openers may be capped at $500 to $1,000. Comparing tiers carefully is essential, which is why our home warranty plans comparison lays out side-by-side caps from leading providers.

How Limits Apply

When you file a claim, the warranty company sends a technician to diagnose the problem. If repair isn't possible and replacement is necessary, the limit determines the maximum payout. For example, with a $2,000 limit on your HVAC system and a $3,000 replacement cost, you'd pay the $1,000 difference plus your service call fee. This is why understanding your home warranty payout limits is crucial for budgeting.

Service Call Fees

Every claim requires a service call fee (also called a trade call fee) that averaged $108.45 in 2026 according to NerdWallet's national analysis, with most providers offering tiered choices of $75, $100, or $125. Some options go as high as $150, and This Old House survey data shows homeowner satisfaction drops sharply once fees exceed that threshold. Choosing a higher service fee usually lowers your monthly premium, and vice versa.

Annual Aggregate Limits

Some plans impose total annual payout caps across all claims. Once you reach this limit (often $25,000 to $50,000), coverage stops until your plan renews, even for otherwise covered items. American Home Shield ShieldPlatinum, for example, carries a $50,000 aggregate cap, while some premium plans offer higher limits for homes with multiple older systems and appliances.

Depreciation Considerations

While warranties cover repairs and replacements, they don't always provide like-for-like replacements for older items. Some plans factor in depreciation, providing lower payouts for older appliances or systems. Others offer trade-in credits toward upgraded replacements when your item exceeds certain age limits, typically 10 to 15 years.

Component Exclusions Within Covered Items

Even when a system or appliance is covered, specific components may be excluded, creating coverage gaps homeowners should understand before purchasing. This is especially true for energy-efficient systems where specialty parts often fall outside standard coverage.

HVAC Component Exclusions

While HVAC systems are covered, exclusions often include refrigerant lines, condensate pumps (sometimes), humidifiers, air purifiers, electronic air cleaners, and inaccessible ductwork. Some plans also exclude heat pump reversing valves or certain types of heating systems like radiant floor heating. The 2025 EPA A2L refrigerant mandate has created a new coverage gap in 2026: if a legacy R-410A component fails, warranties typically cover only the failed part, leaving homeowners to pay thousands to replace still-working but now incompatible indoor units. A few providers now offer HVAC incompatibility riders (up to about $5,000) that specifically address this scenario.

Plumbing Component Exclusions

Covered plumbing systems may exclude drain line stoppages caused by roots, main sewer line issues, water softeners, reverse osmosis systems, instant hot water dispensers, bidets, and saunas. Drainage problems from external sources like tree roots often require special add-ons costing $10 to $15 monthly.

Appliance Component Exclusions

Refrigerators may exclude ice makers or water filters despite covering the main cooling system, along with freestanding freezers, mini-fridges, and wine chillers. Ovens might exclude self-cleaning mechanisms, oven racks, door glass, or interior lights even when heating elements are covered. Washing machines may exclude agitators or drums in certain circumstances. Always review the component list in your contract before purchase.

Water Heater Exclusions

While water heaters are covered, expansion tanks, pressure relief valves, and solar water heating components are frequently excluded. Units over specified gallon capacities (typically 50 gallons) may require upgraded coverage at additional cost. Some plans also exclude tankless water heater repairs despite covering traditional tank models.

Electrical Component Exclusions

Doorbells, intercoms, landscape lighting, exterior outlets, and certain smart home electrical components often fall outside standard electrical coverage. Ground fault issues in exterior circuits may be excluded, requiring homeowners to pay $300 to $800 for repairs out of pocket.

Frequently Asked Questions

Does a home warranty cover appliances that came with my house?

Yes, home warranties cover appliances included with your home purchase as long as they're in working condition when coverage begins and aren't subject to pre-existing conditions. However, there's typically a 30-day waiting period after purchase before coverage activates, preventing coverage of items that were already malfunctioning at closing. Most plans require that covered appliances are properly installed and maintained according to manufacturer specifications. Keep your home inspection report and appliance receipts to document their working condition at the time of coverage purchase.

What is the difference between a home warranty and homeowners insurance?

Home warranties cover mechanical breakdowns and normal wear and tear on systems and appliances, while homeowners insurance covers damage from specific perils like fire, theft, or weather events. Insurance handles structural damage and liability issues, whereas warranties address the gradual failure of working components. You need both types of coverage for comprehensive home protection, as they serve distinctly different purposes and don't overlap. Learn more in our home warranty vs insurance guide.

Are pre-owned or used appliances covered under home warranties?

Yes, most home warranties cover pre-owned and used appliances as long as they were in proper working condition when your coverage began and meet the plan's age and condition requirements. However, some plans may limit coverage for items over 10 to 15 years old or require higher service fees for older appliances. The key factor is that the appliance cannot have pre-existing problems when your policy starts, regardless of age. Some premium plans offer enhanced coverage for older homes with aging systems and appliances.

How do coverage limits affect my out-of-pocket costs?

Coverage limits cap what the warranty company pays for each repair or replacement, so you'll pay any amount exceeding the limit plus your service call fee. For example, if your plan has a $2,000 refrigerator limit but replacement costs $2,800, you'll pay the $800 difference plus a service fee of $75 to $150. Higher premium plans with increased limits reduce these potential out-of-pocket expenses, making them valuable for homes with expensive appliances or systems. Understanding these limits before purchasing helps you budget accurately for potential repair scenarios.

Can I add coverage during my policy year if I need it?

Most home warranty companies require that add-ons be purchased either at the time of initial enrollment or during your annual renewal period. Mid-term additions typically aren't allowed as this prevents adverse selection where homeowners only add coverage when they anticipate a problem. Some companies may make exceptions, but expect waiting periods of 30 days or more before new add-on coverage becomes effective to prevent claims on known issues. Plan your coverage needs carefully at enrollment to avoid gaps in protection throughout your policy year.
