Home Warranties: What They Cover and Whether You Need One

A home warranty is not home insurance. Home insurance covers damage from events like fires, storms, and theft. A home warranty is a service contract that covers the repair or replacement of home systems and appliances that break down from normal wear and tear. The industry generates over $3 billion in annual revenue, and consumer complaints about home warranty companies consistently rank among the highest at the Better Business Bureau. Here is what these contracts actually cover, what they exclude, and whether they are worth the money for your situation.

What Home Warranties Cover

Home warranty plans generally fall into three tiers:

Systems Plan ($300-$400/year)

Covers major home systems:

• HVAC (heating, ventilation, air conditioning)
• Electrical system
• Plumbing system (pipes, water heater)
• Ductwork

Appliances Plan ($300-$400/year)

Covers major kitchen and laundry appliances:

• Refrigerator
• Oven, range, and cooktop
• Dishwasher
• Washer and dryer
• Built-in microwave
• Garbage disposal

Combo Plan ($400-$600/year)

Covers both systems and appliances. This is the most common plan type. Optional add-ons (pool, spa, septic, well pump, roof leak repair) cost $50 to $200 each per year.

Service Call Fees

Every time you file a claim and a technician comes to your home, you pay a service call fee (also called a trade call fee or deductible). This ranges from $75 to $125 per visit, depending on the company and plan level. Some companies offer lower annual premiums with higher service fees, and vice versa.

The service call fee applies regardless of whether the company approves the repair. If the technician determines the problem is not covered (pre-existing condition, improper maintenance, code violation), you still pay the service fee and get nothing.

What Home Warranties Exclude

This is where the reality diverges from the marketing. Every home warranty contract contains exclusions that significantly limit coverage:

• Pre-existing conditions: If the system or appliance was already broken or showing signs of failure when the contract started, the claim will be denied. Companies use inspection records, home sale disclosures, and technician assessments to identify pre-existing conditions.
• Improper maintenance: If you did not maintain the equipment according to manufacturer guidelines (annual HVAC servicing, water heater flushing, etc.), the company can deny the claim. Some companies request maintenance records.
• Code violations: If the equipment does not meet current building codes, repairs or replacement may be denied or only partially covered.
• Coverage caps: Most plans cap payouts at $1,500 to $3,000 per item per year. A new HVAC system costs $5,000 to $12,000. A new roof costs $8,000 to $15,000. The warranty will not cover the full replacement cost.
• Cosmetic damage: Dents, scratches, and surface damage are not covered even if the appliance functions.
• Permits and code upgrades: If a repair requires a permit or bringing the system up to current code, those costs are typically your responsibility.
• Access issues: If the technician needs to open a wall, remove tiles, or otherwise access a system, the cost of gaining access (and repairing the damage afterward) is usually not covered.

Claim Denial Rates

The home warranty industry does not publish official denial rates, but consumer complaint data tells the story. The BBB, state attorneys general offices, and the CFPB have received thousands of complaints about denied claims, long wait times for repairs, and low-quality replacement parts.

Common denial reasons:

• Pre-existing condition (the most frequently cited reason)
• Lack of maintenance documentation
• "Not a mechanical failure" (the company argues the problem is something other than normal wear and tear)
• Exceeding the coverage cap
• The specific component that failed is not listed in the contract

Read the contract carefully before purchasing. The marketing says "we cover your HVAC." The contract specifies which HVAC components are covered, which are excluded, and under what conditions. These are different things.

When a Home Warranty Makes Sense

• Your home is 10+ years old and major systems (HVAC, water heater, appliances) are approaching end of life. The probability of a covered repair exceeds the annual premium.
• You have limited savings and a $5,000 HVAC replacement would be financially devastating. The warranty functions as budgeting insurance.
• You just bought the home and do not know the condition of the systems. Sellers sometimes provide a home warranty as part of the sale. Use the first year to assess and budget for replacements.
• You do not have a trusted contractor network and want a company to dispatch technicians. The convenience has value even if the financial math is marginal.

When a Home Warranty Does Not Make Sense

• Your home is new or recently renovated with systems and appliances still under manufacturer warranty. You would be paying for duplicate coverage.
• You have an emergency fund of $5,000 or more. Self-insuring by setting aside $500 per year into a home repair fund is almost always cheaper over time than paying warranty premiums plus service fees, especially given claim denial rates.
• You have reliable contractors you trust. A good HVAC technician with a maintenance agreement will cost less than a warranty and provide better service.
• You are a handy homeowner who can diagnose and handle minor repairs. The warranty's value proposition is primarily the labor, not the parts.

The Math

A typical combo plan costs $500 per year plus $100 per service call. Over 5 years, you pay $2,500 in premiums. If you make 3 service calls per year, add $1,500. Total 5-year cost: $4,000.

For that $4,000, you need to receive at least $4,000 in covered repairs to break even. Given coverage caps ($1,500 to $3,000 per item) and denial rates, many homeowners pay more in premiums and service fees than they receive in repairs. The warranty company would not be profitable otherwise.

The alternative: put $500 per year into a dedicated savings account. After 5 years, you have $2,500 (plus interest) available for any repair, with no exclusions, no denials, and no service fees.

How to Choose a Company (If You Decide to Buy)

• Read the sample contract before purchasing, not just the marketing materials. Look for coverage caps, exclusions, and the claims process.
• Check the company's BBB rating and complaint history. Pay attention to the pattern of complaints, not just the rating.
• Verify the cancellation policy. Some companies charge a cancellation fee or pro-rate refunds unfavorably.
• Ask about contractor quality. Some companies use the cheapest available contractors, leading to poor workmanship and repeat issues.
• Understand the claims process. How do you file? How long until a technician arrives? What happens if you disagree with the denial?

Bottom Line

Home warranties are a form of risk management, not a money-saving tool. They make the most sense for homeowners with older systems, limited savings, and a low tolerance for unexpected repair bills. For homeowners who can self-insure with a dedicated repair fund, the math usually favors skipping the warranty. If you do buy one, read every word of the contract — especially the exclusions — so you know exactly what you are paying for.
