Should You Buy a Home Warranty? What the Coverage Actually Costs and Covers

A home warranty is worth it only if you own an older home, plan to stay put for several years, and can afford the annual premium without straining your budget

Home warranties are insurance contracts that cover the repair or replacement of major systems and appliances when they break down from normal wear. They cost between $400 and $900 per year, depending on what you include and where you live. The real question is not whether they sound useful — it is whether you will actually come out ahead, given what they exclude and how much you will pay in premiums over time.

A warranty makes the most sense if your water heater, HVAC system, or electrical panel is already ten years old or older. It makes less sense if you just bought a new home with new systems, or if you have the cash reserves to replace a $5,000 furnace without borrowing. It almost never makes sense if you are selling the home within two years, because most warranties do not transfer to the new owner.

Key Takeaways

• Home warranties typically cost $400 to $900 per year and cover repair or replacement of major systems and appliances, but they exclude pre-existing damage, poor maintenance, and many common failure modes.
• You pay a service call fee ($75 to $150 per visit) every time you make a claim, so the warranty does not eliminate your out-of-pocket costs.
• Warranties are most useful for older homes with aging systems, less useful for new construction or if you have savings to cover major repairs yourself.
• The warranty company, not you, chooses the contractor, which can mean longer wait times and lower-quality repairs than hiring your own professional.

What home warranties actually cover and exclude

A standard home warranty covers the repair or replacement of major systems: HVAC, plumbing, electrical, water heater, and built-in appliances like ovens and dishwashers. Some plans add coverage for roof leaks, pool equipment, or garage door openers for an extra fee. The contract specifies a maximum payout per claim and per year, often $5,000 to $10,000 total annually.

What they do not cover is just as important. Most warranties exclude damage from poor maintenance, lack of use, or pre-existing conditions — meaning if your furnace was already broken when you bought the warranty, it stays excluded. They also exclude damage from natural disasters, pest infestations, code violations, and systems that were installed incorrectly. If a plumber installed your water heater wrong five years ago and it finally fails, the warranty company can deny the claim.

You also pay a service call fee every time you file a claim, usually $75 to $150. This means a $3,000 water heater replacement costs you $75 to $150 out of pocket, plus the warranty premium you already paid. The warranty company, not you, picks the contractor, and you have limited say in whether they use the cheapest option or the best one.

When the math works in your favor

A warranty pays for itself only if you make enough claims to exceed the total premiums you paid. If you pay $600 per year and own the home for five years, you need to file claims totaling more than $3,000 just to break even. That means at least two major repairs, or one very expensive one.

Older homes are more likely to hit that threshold. If your furnace is 15 years old, your water heater is 12 years old, and your electrical panel is original to the 1970s house, the odds of at least one major failure in the next few years are high. A warranty in that situation might save you money. If you just bought a new construction home with a builder's warranty on all systems, a home warranty is redundant.

The math also depends on your financial situation. If you have $10,000 in emergency savings and can absorb a $5,000 furnace replacement without going into debt, a warranty is a luxury, not a necessity. If you have $2,000 in savings and a major system failure would force you to borrow, a warranty shifts that risk to the insurance company — and that shift has real value, even if you never file a claim.

The hidden costs and limitations of using a warranty

When you file a claim, the warranty company dispatches a contractor from their network. You do not choose this contractor, and the company prioritizes cost over speed or quality. Wait times can stretch to two weeks, which is a problem if your air conditioning fails in July or your furnace in January. If you call your own plumber, you can often get same-day service.

The contractor the warranty company sends may also push back on the claim or recommend a repair instead of replacement to save the company money. If you disagree, you can appeal, but that takes time and documentation. If you hired your own contractor, you would have more control over the decision.

Some warranty companies also have limits on how many claims you can file per year, or they will drop you if you file too many claims. Read the fine print on this before you buy. A few companies reserve the right to cancel your coverage if you make more than three claims in a year, which defeats the purpose of having insurance.

Home warranties versus home insurance and builder warranties

Do not confuse a home warranty with homeowners insurance. Homeowners insurance covers sudden damage from fire, theft, or weather. A home warranty covers breakdowns from normal wear and tear. You need both, and they serve different purposes.

If you just bought a new home, check whether the builder included a warranty on the structure and systems. Most builders offer a one-year warranty on workmanship and a ten-year structural warranty. This covers defects from construction, not normal wear. Once that builder warranty expires, a home warranty becomes more relevant.

If you are buying a used home, the seller may have transferred their warranty to you, or you may be able to purchase a warranty as part of the closing process. Some real estate agents bundle a one-year warranty into the sale as a selling point. Read what it covers before you assume it is valuable — many of these bundled warranties have high service call fees and low payout limits.

Alternatives to buying a home warranty

Instead of a warranty, you could set aside $100 to $150 per month in a dedicated home repair fund. Over five years, that is $6,000 to $9,000, enough to cover most major system failures. This approach gives you full control over which contractor you hire and how quickly you get service. The downside is that it requires discipline — if you raid the fund for other expenses, you will not have it when you need it.

Another option is to prioritize preventive maintenance. A furnace that is serviced annually lasts longer than one that is ignored. A water heater that is flushed yearly performs better than one that is not. Spending $200 to $400 per year on maintenance can extend the life of your systems by several years, which may delay or prevent the need for expensive repairs altogether.

If you are buying an older home and want protection but do not want to pay for a warranty, you could negotiate with the seller to lower the purchase price by $2,000 to $3,000 and use that money to cover repairs yourself. This gives you more flexibility than a warranty and costs less if you do not need major repairs.

How to decide whether a home warranty makes sense for you

Start by listing the age of your major systems: furnace, water heater, air conditioning, electrical panel, plumbing. If most are over ten years old, a warranty is worth considering. If most are under five years old, it probably is not.

Next, check your emergency savings. If you have less than $5,000 set aside for unexpected expenses, a warranty reduces your financial risk. If you have $15,000 or more, you can likely absorb a major repair without one.

Then, read the specific contract from the warranty company you are considering. Look for the service call fee, the annual payout limit, the list of exclusions, and the cancellation clause. Compare the cost of the warranty over three years to the cost of replacing one major system. If the warranty costs $2,000 over three years and a furnace replacement costs $5,000, the warranty breaks even if you need one furnace replacement in that window.

Finally, ask yourself how long you plan to stay in the home. If you are selling within two years, a warranty is almost certainly not worth it. If you plan to stay ten years or more, the odds of multiple major repairs increase, and a warranty becomes more attractive.

Frequently Asked Questions

Does a home warranty cover my roof?

Most standard home warranties do not cover roof leaks or roof replacement. Some companies offer roof coverage as an add-on for an extra $100 to $200 per year, but it usually covers only leaks from normal wear, not damage from storms or poor installation. Check the specific contract before you buy.

Can the warranty company refuse to pay for a repair?

Yes. Warranty companies can deny claims if they determine the damage is from poor maintenance, pre-existing conditions, or improper installation. If you disagree with a denial, you can appeal, but you will need documentation showing the system was maintained properly. Keep records of any service calls or maintenance you have done.

What happens to my warranty if I sell the home?

Most home warranties do not transfer to the new owner. Some companies offer a transfer option for a fee, usually $100 to $200, but the new owner would need to agree to it. If you are selling, check your contract to see whether transfer is possible and whether it is worth the cost.

Is a home warranty worth it for a new construction home?

Probably not. New construction homes come with a builder's warranty that covers defects for one to ten years, depending on what failed. A home warranty would duplicate that coverage for the first year or two. Wait until the builder's warranty expires before considering a home warranty.

How long does it take to get a repair done under warranty?

Wait times vary by company and region, but two to seven business days is typical. Emergency calls (no heat in winter, no water) may be prioritized, but you should not count on same-day service. If you need immediate repairs, you may have to pay out of pocket and then file a claim for reimbursement.
