If you’ve ever had an air conditioning unit go out in the middle of summer or a refrigerator die right before a big holiday gathering, then you’re familiar with some of the appliances a home warranty can cover. Instead of maintaining several warranties on individual appliances and systems, a home warranty covers service, repair, or replacement of your home’s major systems and appliances under one contract.

When unexpected breakdowns occur, it can be difficult to quickly arrange repair service and budget for large out-of-pocket replacement costs. However, for a monthly or annual fee, a home warranty plan gives you peace of mind by helping mitigate these costs if a home system or appliance fails.

The 2021 Best Home Warranty Companies rating is based on research performed and data collected in October 2020.

Roof coverage can be tricky. If your roof is damaged by fire or an act of nature, your homeowners insurance will normally cover it. However, routine roof maintenance or wear and tear can be excluded from a homeowners insurance policy. For that reason, when deciding on a home warranty plan, one of the first things customers look for is roof coverage.

Although roof coverage normally costs extra, some home warranty companies do offer limited roof leak coverage as part of a standard plan. That means the home service plan can help repair a minor problem with the roof, though the coverage doesn’t typically include drywall damage or other issues that may be caused by a leaking roof. Like other items in a home warranty contract, there are exclusions and limitations that apply to roofs, and coverage varies between companies. Some companies like Landmark Home Warranty, for example, have a roof repair limit of $1,000. Others, like Choice Home Warranty, place the cap a bit lower, at $500 on the repair costs. When coverage is included, it can be very specific. Select Home Warranty is a good example. It only covers leaks over an occupied living area in a single-family house.

No matter which company you choose, be sure to review your contract to see what is covered and what is not. To learn more about home warranty coverage visit, What Does a Home Warranty Cover?

Not all home warranty companies provide service in all states, so your first task when shopping for a home warranty is to find the options that are available in your area. Use the map below to determine which of our Best Home Warranty Companies of 2021 sell home warranty contracts in your state.

At the time of our review, only Home Warranty of America offered nationwide coverage. However, as home warranty companies continue to expand their reach and as many independent contractors relocate throughout the U.S., more companies may offer nationwide service.

A home warranty, also known as a home service contract, will pay for unexpected home repairs or replacements for major appliances and home systems, such as refrigerators, water heaters, plumbing systems, electrical systems, garage door openers, and heating and air conditioning units. Homeowners may not have budgeted for such repairs, which can cost up to hundreds or thousands of dollars. Home systems in particular can be expensive to repair, and if you don't have the money, you'll be left without heating, air conditioning, electricity, or another major component, which could make your home uninhabitable. In addition, it can take a lot of time to research and find a reliable service contractor you trust, who can complete the job efficiently and within your budget.

Having a home warranty can streamline this process for you and take the guesswork out of finding a reputable technician. For a monthly or annual fee, a home warranty gives you access to already vetted and certified technicians as well as repairs – sometimes at a fraction of the normal cost. When an item or system breaks, you call your home warranty provider, and a customer service representative will initiate your claim. All you need to pay is the service fee, which can range from $35 to $125. Your home service plan will only pay for items that are covered under your contract. You will have to pay for additional repairs or exclusions.

Be sure to note that home warranty plans are different from homeowners insurance. Home warranties will cover your home’s main systems and appliances if they fail and require repair or replacement, but home warranty plans do not cover walls, foundation, or flooding. However, a homeowners insurance covers your home’s structure and damage resulting from theft, insects, water, fire, or acts of nature if those items are listed in the policy.

In summary, a home warranty provides a safety net. You won't have to worry if a major appliance or system breaks, leaving you with the choice of living without it or putting an expensive repair bill on your credit card, since you know you'll be covered with your home warranty plan.

As a homeowner, choosing a home warranty requires determining your coverage needs, getting quotes from reputable companies, and understanding exactly what is and isn't covered.

1. Determine your coverage needs. Take an inventory of all of your home's major appliances and systems. You probably won't want to purchase home warranty coverage for newer items that are unlikely to break anytime soon, and home warranties won't cover those that are still under their manufacturers' warranties. By contrast, if you have an older refrigerator, a furnace that could be on its last legs, or some other major system or appliance that could fail and present you with a major repair bill, these are the items you should consider covering with a home warranty.

2. Get quotes and coverages from several reputable companies. Don't just rely on a quick Google search. Read about good home warranty companies like the ones in this guide, and ask friends and neighbors what companies they use. If you're buying a home, ask your real estate agent, who can probably recommend reliable companies.

3. Make sure you understand the coverage. Read the fine print to find out exactly what is and isn't covered, along with how much you'll be reimbursed for replacing a given item if you're buying replacement coverage. Don't overlook a company's terms and conditions or assume that something is covered when it might not be.

For more information, see How to Buy a Home Warranty.

A home warranty is an added protection on your home appliances and systems. It’s not to be confused with homeowners insurance, which will cover the cost of damage to the structure of your home as well as the things in it due to an event like a fire, storm, other natural disaster, or theft. A home warranty, on the other hand, covers repairs of specific elements in your home that can fail or malfunction due to normal wear and tear.

If a covered appliance or system, such as a washing machine or an HVAC system, has a problem or stops working entirely, you don’t need to find a repair technician and pay for their service entirely out of pocket. With a home warranty, you submit a service request to your home warranty company. The company will then send a technician to repair or replace the item.

Be aware that the specifics of home warranty plans can vary. Some are designed to just cover appliances, like refrigerators or dishwashers, while others are for systems, like heating or electrical. When shopping for a home warranty plan, make note of what each plan covers and whether or not you’ll need to purchase add-on coverage for specific appliances.

A home warranty will pay to service, repair, or replace major home appliances and systems. However, you only have coverage for what's specifically listed in the contract, and there are always exclusions that you need to read carefully. For example, while your refrigerator might be covered, the ice maker probably isn't. Moreover, less vital items like pool and spa equipment might not be covered by a basic plan and will require add-on coverage, or they might be excluded entirely. The fine print of every home warranty contract lists exactly which systems, appliances, and appliance components are covered and which are the homeowner's responsibility.

If you want a home warranty that only covers appliances or one that only covers systems, that's often an option. This can be useful if some of your systems and appliances are still under manufacturers' warranties, in which case most home warranties wouldn't cover them.

If you have older appliances and systems that might malfunction at some point and want financial protection when it comes time to repair or replace them, a home warranty could be a good choice.

On the other hand, if your appliances and systems are still covered by manufacturers' warranties, a home warranty won't cover them and isn't necessary in any event. A home warranty also won't cover an appliance or system that has a history of malfunctioning or poor maintenance, and few cover building code issues, or items that weren’t installed properly.

A home warranty can cost on average anywhere from about $300 to $700 a year. The most comprehensive coverage options for our top-rated home warranty companies vary from $510 to $675 per year. With some companies, you can lower your monthly bill by choosing a higher service fee. In addition, it's often cheaper to pay annually rather than monthly. For example, the warranty might cost $50 per month or $570 for 13 months. In this example, opting for the annual plan over monthly payments saves you $80. The key is to compare plans to determine what you're really getting for the price.

Home warranty costs also involve service fees if someone comes out to repair a system or appliance. Below are the service fees charged by our top home warranty companies.

Select a company that can meet your coverage needs, which you can determine by noting the approximate age, condition, and service histories of your major appliances and systems. The newer they are – especially if they're still covered under manufacturers' warranties – the less likely you'll need a warranty to cover the cost of repairing or replacing them. However, older appliances and systems might need protection, assuming they're currently working properly and don't have a history of breaking down due to pre-existing conditions (which a home warranty won't cover).

In addition to coverage needs, consider these factors:

  • If your systems or appliances may have pre-existing conditions, consider a warranty that requires a home inspection. This is likely to uncover hidden issues that might preclude coverage, which will eliminate unpleasant surprises down the road.
  • The cheaper the item, the less likely you are to need coverage for it. You can probably skip a warranty that covers smaller items like microwaves, for example.
  • If you prefer to work with certain contractors, consider a home warranty plan that lets you request specific individuals. Many contracts leave this selection to the home warranty company.
  • Look for a warranty company that has a nearby claims office and is accredited by a reputable organization like the National Home Service Contract Association.

If your home’s major appliances and systems are new or still covered by manufacturers’ warranties then it doesn’t make much sense to purchase a home warranty plan to cover them. In fact, it’s likely that most of those items would be excluded from coverage under your home warranty contract.

Be straightforward when accessing your needs. Consider the installation and repair history of your home’s systems and appliances and be honest about how the item performs. If there is a history of breakdowns, poor maintenance, or improper installation there’s a chance the home warranty company may not cover it. Therefore, purchasing coverage for those items could be more costly than helpful in the long run. Likewise, look out for coverage on less expensive items like microwaves, or certain garage door openers. Appliances such as these are not usually worth paying extra to include them in the contract because their replacement cost can be much lower.

If you’re a home buyer or seller, purchasing a home warranty can make a difference in the asking price and offers given for your home. See Buyers’ vs. Sellers Incentives to Buy a Home Warranty to learn more.

The following describes our 360 approach to researching and analyzing home warranties to provide guidance to prospective consumers.

1. We researched the companies and products people care most about.

U.S. News analyzed and compared a variety of publicly available data, including internet search data, to determine which home warranty companies Americans are most interested in. We found 19 companies that stand out in terms of volume of searches and research among consumers, as well as across the different rating sources.

We then compared the available home warranties provided by our top home warranty companies across several criteria, including cost, appliances and systems covered, unique warranty features, customer satisfaction, and availability. Research shows that these are the most important criteria for people shopping for a home warranty. We compared the costs across different companies and plan types using an archetype that, as much as possible, captured the features of a standard American home: A 2,500 sq. ft. single-family home in Austin, Texas. We compared the most comprehensive plans offered by each company, including coverage for a combination of home appliances and systems.

2. We created objective 360 Overall Ratings based on an analysis of third-party reviews.

U.S. News’ 360 Reviews team applied an unbiased methodology that includes opinions from third-party reviews as well as consumer reviews.

Our scoring methodology is based on a composite analysis of the ratings and reviews published by credible third-party professional and consumer review sources. The ratings are not based on personal opinions or experiences of U.S. News. To calculate the ratings:

(a) We compiled two types of third-party ratings and reviews:

  • Professional Ratings and Reviews. Many independent home warranty evaluating sources have published their assessments of home warranty companies and their products online. We consider several of these third-party reviews to be reputable and well-researched. However, professional reviewers often make recommendations that contradict one another. Rather than relying on a single source, U.S. News believes consumers benefit most when these opinions and recommendations are considered and analyzed collectively with an objective, consensus-based methodology.
  • Consumer Ratings and Reviews. U.S. News also reviewed published consumer ratings and reviews of home warranty providers. Sources with a sufficient number of quality consumer ratings and reviews were included in our scoring model.

Please note that not all professional and consumer rating sources met our criteria for objectivity. Therefore, some sources were excluded from our model.

(b) We standardized the inputs to create a common scale.

The third-party review source data were collected in a variety of forms, including ratings, recommendations and accolades. Before including each third-party data point into our scoring equation, we had to standardize it so that it could be compared accurately with data points from other review sources. We used the scoring methodology described below to convert these systems to a comparable scale.

The 360 scoring process first converted each third-party rating into a common 0 to 5 scale. To balance the distribution of scores within each source’s scale, we used a standard deviation (or Z-Score) calculation to determine how each company’s rating compared to the source’s mean score. We then used the Z-Score to create a standardized U.S. News score using the method outlined below:

  • Calculating the Z-Score: The Z-Score represents a data point's relation to the mean measurement of the data set. The Z-Score is negative when the data point is below the mean and positive when it's above the mean; a Z-Score of 0 means it's equal to the mean. To determine the Z-Score for each third-party rating of a company, we calculated the mean of the ratings across all companies evaluated by that third-party source. We then subtracted the mean from the company’s rating and divided it by the standard deviation to produce the Z-Score.
  • Calculating the T-Score: We used a T-Score calculation to convert the Z-Score to a 0-100 scale by multiplying the Z-Score by 10. To ensure that the mean was equal across all data points, we added our desired scoring mean (between 0 and 10) to the T-Score to create an adjusted T-Score.
  • Calculating the common-scale rating: We divided the adjusted T-Score, which is on a 100-point scale, by 20 to convert the third-party rating to a common 0-5 point system.

(c) We calculated the 360 Overall Score based on a weighted-average model.

We assigned “source weights” to each source used in the consensus scoring model based on our assessment of how much the source is trusted and recognized by consumers and how much its published review process indicates that it is both comprehensive and editorially independent. The source weights are assigned on a 1-5 scale. Any source with an assigned weight less than two was excluded from the consensus scoring model.

Finally, we combined the converted third-party data points using a weighted average formula based on source weight. This formula calculated the consensus score for each product, which we call the 360 Overall Rating.
