Every homeowner gets the pitch eventually. A letter arrives, or a real estate agent mentions it at closing, or a company calls about protecting your major systems and appliances. The pitch is straightforward: pay a few hundred dollars a year, and when your water heater dies or your AC stops working in August, you call the warranty company instead of a repair service.
It sounds reasonable. But home warranties have a complicated reputation, and for good reason. Whether one actually pays off depends almost entirely on your home’s age, what you already own, and how closely you read the contract before signing.
Run your own numbers: Is a Home Warranty Worth It? Calculator
What a home warranty actually covers
A home warranty is a service contract, not an insurance policy. It covers repair or replacement of mechanical systems and appliances that break down due to normal wear. It does not cover damage from neglect, improper installation, or pre-existing conditions.
Most basic plans cover the core systems: heating, cooling, electrical, and plumbing. Appliance coverage (refrigerators, dishwashers, washers, dryers, ovens) usually costs more, either as an upgrade or part of a premium plan.
What they typically do not cover matters just as much. Home warranties almost universally exclude cosmetic damage, secondary damage caused by a covered breakdown, items not maintained properly, and any system or appliance that was already failing before the contract started. That last exclusion is the one that catches most people off guard.
What it costs
Basic home warranty coverage runs $300 to $600 per year for most homeowners, depending on your location, home size, and plan tier. Premium plans with fuller appliance coverage and lower service call fees run $600 to $1,100 annually.
Every service call also has a fee, typically $75 to $125, that you pay regardless of whether the repair is covered or how much the fix costs. If the contractor determines the issue is not covered under your plan, you owe the service fee and still pay full price for the repair.
So your actual annual cost is: monthly premium times twelve, plus service call fees for each claim you file.
When the math actually works
The case for a home warranty is strongest in three situations.
Older home with aging systems. HVAC systems typically last 15 to 20 years. Water heaters last 8 to 12 years. If your major systems are in the back half of their expected lifespan, your probability of a costly breakdown in any given year is meaningfully higher. A central air conditioning unit replacement runs $3,800 to $7,500 installed, according to Angi’s cost data. A furnace replacement runs $2,500 to $6,000. One of those claims pays for several years of warranty premiums.
Low cash reserves. If a $4,000 HVAC repair would genuinely strain your finances, a warranty converts that unpredictable large expense into a predictable small one. This is essentially the same logic as any insurance product, you are trading certainty for potentially paying more in total. Whether that tradeoff is worth it depends on your personal liquidity, not just the math.
Recent home purchase. The first year in a new home carries more uncertainty than most. You do not fully know what was properly maintained and what was deferred. A warranty during that transition period acts as a buffer while you learn the property.
When it does not make sense
New construction. New homes come with builder warranties covering structural defects and workmanship, and most major appliances still carry manufacturer warranties. Adding a home warranty on top of coverage you already have creates overlap without much additional protection.
Newer systems and appliances. If your HVAC is four years old and your water heater was replaced two years ago, the probability of a major failure in the next twelve months is low. You are paying annual premiums to protect against an event that has a small chance of occurring and would be covered by manufacturer warranties anyway.
Highly renovated or custom homes. Non-standard systems and high-end appliances are frequently excluded or have limited coverage caps that fall well short of actual replacement costs. If your kitchen has a commercial-grade range or your home uses a geothermal heat pump, read the contract carefully before assuming it is covered.
Three homeowners, three different answers
The 1990s colonial with original HVAC
Home purchased in 2019. Original HVAC system, installed 1998. Water heater replaced in 2021. Warranty plan cost: $520/year plus $100 service fee per call.
In year two of ownership, the air handler fails in July. Repair estimate from an independent contractor: $1,800. Covered under the warranty after the service fee. Net savings: $1,700 on a single claim.
Over five years, she paid $2,600 in premiums and filed two claims totaling $3,200 in covered repairs, minus two service fees. Net benefit: roughly $400 ahead, plus the peace of mind during years with no claims.
Worth It Score: 71. Aging systems made the warranty genuinely useful.
The 2019 build with all new systems
Purchased new in 2020. All systems and appliances under manufacturer warranty through 2022 to 2025. Home warranty offered at closing for $480/year.
Over four years, filed one claim for a dishwasher motor: covered repair value $340, after a $100 service fee. Total premiums paid: $1,920. Net loss: $1,680.
Worth It Score: 22. Newer construction with active manufacturer coverage does not benefit from stacking a home warranty on top.
The 1970s fixer-upper, bought as-is
Purchased with known deferred maintenance. HVAC replaced during renovation. Plumbing partially updated. Water heater is original from the mid-2000s.
Warranty enrolled at purchase. In the first year, water heater fails and is replaced. Covered. In year two, garbage disposal and dishwasher both need service. Both covered. Three years of premiums: $1,560. Three years of covered work: approximately $2,400. Net benefit: $840.
Worth It Score: 76. The combination of unknown history and older systems made coverage pay off quickly.
What to look for in the contract before you sign
Coverage limits per item matter more than the total plan cost. Some warranties cap HVAC coverage at $1,500, which barely covers a service visit for a major system, let alone replacement. Read the per-item limits for the systems you are most concerned about.
Contractor assignment is the other thing to check. Most home warranty companies dispatch their own contractors, not the ones you would choose. You typically cannot request a specific provider. If having control over who works on your home matters to you, this can be a dealbreaker.
Review the exclusions list carefully. Pre-existing conditions, improper installation, and lack of maintenance documentation are the most common reasons claims get denied. If you cannot produce maintenance records for your HVAC, the warranty company may argue the breakdown was due to deferred maintenance and decline the claim.
How the calculator works
The home warranty calculator asks about your home’s age, the age of your major systems, your current emergency savings, and how many systems you are most concerned about. It runs those inputs against the statistical probability of a costly repair in the next twelve months and compares that against your expected annual warranty cost.
A Worth It Score below 30 means the math does not support a warranty for your situation right now. Between 31 and 70, it depends heavily on your personal risk tolerance and cash position. Above 70, the combination of older systems and repair probability makes coverage financially sensible.
The bottom line
A home warranty is not a scam. It is also not a guarantee. It is a service contract that works well for homeowners with older systems and limited cash reserves, and works poorly for homeowners with newer systems or high-end non-standard equipment.
The question is not whether home warranties ever pay off. The question is whether the specific contract you are considering covers what you are most likely to need, at a price that makes the risk tradeoff worth it for your home.
