A friend of mine closed on her first house last spring. Three weeks later, the HVAC quit on a 97-degree afternoon. She called the home warranty company the seller had included as a closing concession. Six days and two phone trees later, a technician showed up, poked around the condenser for twenty minutes, and told her the compressor failure was a "pre-existing condition." Claim denied. She paid $6,800 out of pocket for a new unit.
Her story isn't unusual. Home warranty companies spend a lot of money on advertising, and the pitch is simple: pay a small annual premium, and when something breaks, you're covered. But the gap between the marketing and the actual experience can be wide. So let me walk through the real numbers, the fine print, and when these plans actually make sense.
What a home warranty covers (and what it doesn't)
A home warranty is a service contract, not insurance. You pay an annual premium, and in return the company agrees to repair or replace covered systems and appliances when they break from normal wear and tear.
Most basic plans cover your HVAC, plumbing, electrical, water heater, and major kitchen appliances. Comprehensive plans add your washer, dryer, garage door opener, and sometimes your roof leak coverage. On top of the annual premium, you'll pay a service call fee (sometimes called a "trade fee") every time a technician visits.
Here's what trips people up: the exclusions list. Common carve-outs include pre-existing conditions, improper maintenance, code violations, and cosmetic damage. If you haven't had your HVAC serviced annually, the company can argue the breakdown resulted from neglect. That argument is hard to fight.
The real cost breakdown
According to ConsumerAffairs, the average annual premium for a home warranty plan is about $1,049, with plans ranging from $222 to $1,877 depending on coverage level. Service call fees run $75 to $125 per visit.
Let's say you buy a mid-tier plan for $600 a year and file two claims. That's $600 plus two service calls at $100 each, so $800 total for the year.
Now compare that to typical repair costs. A dishwasher repair runs $100 to $200. A washer repair costs $150 to $500. A refrigerator fix is $200 to $400. For most individual appliance repairs, you'd spend less paying out of pocket than you would on the warranty premium plus the service fee.
The math changes when you're talking about big-ticket systems. Replacing a central air conditioner costs $5,000 to $12,500, according to industry data. A furnace replacement runs $3,000 to $7,000. A water heater is $1,500 to $3,500. Those are the numbers that make the warranty sound appealing.
But there's a catch: coverage caps.
Coverage caps quietly gut your protection
Most home warranty contracts include per-item or per-system caps that range from $1,500 to $3,000. If your HVAC compressor fails and the replacement costs $8,000, the warranty might cover $2,500 of that. You're still on the hook for $5,500.
That gap surprises a lot of homeowners. The marketing says "HVAC covered," and technically it is, up to a limit buried on page fourteen of the contract.
HVAC claims have roughly a 78% approval rate, according to ConsumerAffairs data, which is lower than the overall approval rate across all claim types. And among denied claims, the most common reasons were pre-existing conditions and items not covered under the plan, each cited by about 29% of respondents.
The 44% problem
A survey by Consumer Reports found that 44% of home warranty holders had claims denied or only partially paid. That number is hard to ignore.
Industry groups push back on it, citing their own surveys showing 90% approval rates. The discrepancy probably comes down to how you define "approved." A claim that's approved for $1,500 on a $7,000 repair is technically approved. But the homeowner still writes a big check.
The BBB complaints tell a similar story. Choice Home Warranty alone had 10,634 complaints filed over three years, according to the Better Business Bureau. In January 2026, the company settled an Arizona Attorney General consumer fraud lawsuit for $11.8 million, the largest home warranty settlement in Arizona history.
None of this means every warranty company is a scam. Some homeowners have genuinely positive experiences. A This Old House survey found that 83% of warranty holders were satisfied with their current plan, and 88% planned to renew. But satisfaction surveys measure feelings, not financial outcomes. You can be satisfied with the peace of mind while still losing money on the deal.
When a home warranty actually makes sense
There are three narrow situations where the math can work in your favor.
You're buying a home with older systems. If the HVAC is 12 years old, the water heater is pushing 10, and the appliances came with the house from a prior decade, you're sitting on a cluster of potential failures. A warranty won't cover everything, but it reduces your maximum exposure during the first year or two while you figure out what needs replacing on your timeline.
You have less than $3,000 in repair savings. If a single appliance breakdown would put you on a credit card at 24% APR, the predictable annual premium is a reasonable hedge against a cash-flow crisis. This isn't about whether the warranty is a good deal on average. It's about whether you can absorb a $6,000 surprise right now.
The seller is paying for the first year. If the warranty is a free closing concession, take it. File claims aggressively during that year. Just don't auto-renew without running your own numbers.
The self-insurance alternative
For most homeowners with a stable emergency fund, self-insuring is the better play.
Try this instead: take the $600 to $1,000 you'd spend on the warranty premium each year and drop it into a dedicated "home repair" savings account. After three years, you've got $1,800 to $3,000 sitting there. After five years, $3,000 to $5,000. That money covers most appliance repairs outright, and it gives you a meaningful head start on a major system replacement.
The advantages go beyond the math. You pick your own contractor instead of waiting for whoever the warranty company dispatches. You don't spend hours on hold or arguing about whether a claim qualifies. You don't discover coverage caps after the fact. And the money you don't spend on claims stays in your account, growing, rather than disappearing into a warranty company's revenue.
The disadvantage is obvious: if your HVAC dies in year one, you haven't built up the fund yet. That's real risk, and it's why the three scenarios above exist. But over a five- to ten-year homeownership timeline, self-insurance almost always comes out ahead.
How to read a home warranty contract before signing
If you decide a warranty makes sense for your situation, protect yourself.
Read the contract before you buy, not after something breaks. Look for per-item and per-system dollar caps. Check the exclusions list for pre-existing conditions, maintenance requirements, and code-upgrade clauses. Ask whether the company requires you to use their contractors or lets you choose your own. Find out the claims process timeline, because a week without air conditioning in August is not theoretical.
Check the company's BBB rating and complaint history. A company with thousands of complaints and a state attorney general settlement on its record is telling you something.
And always compare the total annual cost (premium plus expected service fees) against what you'd actually spend repairing the items most likely to break. For a newer home with modern appliances, the warranty is almost certainly a bad deal. For an older home with aging systems and a thin savings cushion, it might be worth the trade-off.
The bottom line
Home warranty plans are financial products, and like most financial products, they're designed to be profitable for the company selling them. That doesn't make them useless, but it does mean the average buyer pays more in premiums than they get back in covered repairs.
If you can build a $3,000 to $5,000 home repair fund over the next few years, that money will serve you better than any warranty contract. If you can't, and you're living in a house with aging systems, a warranty can be a reasonable stopgap. Just go in with open eyes, a read contract, and realistic expectations about what "covered" actually means.
