With so many home warranty companies available that claim to offer the most comprehensive coverage, it may be challenging to find the best option for your situation.

If you’re asking yourself, “what does a home warranty cover,” the This Old House Reviews Team will educate you on what you should expect when purchasing a service contract, including coverage, pricing, and limitations.

What’s Covered by a Home Warranty?

Typically, home warranty coverage includes, at least in some aspects, all of the essential systems and appliances you rely on throughout the home. While the extent of coverage may vary significantly between home warranty providers, a policy will generally protect components that are necessary for operation.

It’s common for providers to break up their home warranty plans by systems and appliances. For instance, you may find a systems-only plan is sufficient when protecting your air conditioning and electrical system. On the contrary, an appliance plan provides financial assistance for when your refrigerator or dishwasher breaks down. Most home warranty companies will also include a combo plan where both systems and appliances are under warranty.

Here are just a few of the systems and appliances that are covered under a home warranty

Heating system

Built-in microwave

Home warranty providers are also known for allowing policyholders to increase their coverage by including optional add-ons to a service contract.

Here are a few common add-ons provided by home warranty companies: 

  • Swimming pool and spa equipment
  • Septic tank and pumping
  • Secondary appliances or HVAC systems
  • Limited roof leaks
  • Well pump
  • Pre-season HVAC maintenance
  • Guest units
  • Extended electronic warranty
  • Pest control services
  • Food spoilage due to broken refrigerator
  • Re-key service for doors

We recommend analyzing a sample service contract before signing up for coverage to understand how extensive the coverage is for both the bundled packages, as well as add-ons.

What Does a Home Warranty Not Cover?

Not all types of repairs are covered under home warranty coverage. Here are some common equipment malfunctions that are almost always disqualified under home warranty coverage:

  • Pre-existing conditions at the time a home warranty begins
  • Damage caused by the improper installation or maintenance
  • Misuse of an appliance or system by using it for purposes other than residential use
  • Cosmetic issues

Find out the specific exclusions from a provider by asking a representative or looking for coverage limitations in a sample contract. In addition to excluded repair causes, you should also check the maximum payouts for both appliances and systems—sometimes, a home warranty company will set limits on systems and appliances and once that limit is reached, you’ll be required for paying any extra costs.

What Is a Home Warranty?

A home warranty is an annual service contract that covers repairs and replacements on major home systems and appliances, like air conditioning or a refrigerator, that have failed due to normal wear and tear. This type of home appliance insurance protects homeowners from paying too much out of their own pockets and gives them peace of mind if something unexpected were to happen.

Though similar to homeowners insurance, a home warranty is different because it’s an optional policy that helps cover the costs of unavoidable breakdowns to your home’s systems or appliances. Homeowners insurance, on the other hand, is a mandatory policy that protects your belongings from unexpected events like storm damage, theft, or fire.

Compare what’s covered by home warranties and homeowners insurance in the chart below.

Your appliances are damaged due to a surge caused by lightning.

An air conditioning system begins blowing warm air during operation.

A fire breaks out, leaving a few appliances inoperable.

The washer and dryer begin malfunctioning due to age and normal wear and tear.

When Does Home Warranty Coverage Begin?

With most home warranty providers, a 30-day waiting period is required before coverage begins. Some companies, like The Home Service Club, have only a 10-day waiting period before coverage kicks in, and some companies may allow a seamless transition with proof of uninterrupted service if there’s no lapse in coverage.

How Long Does Home Warranty Coverage Last?

In most cases, a home warranty lasts for 12 months and can be renewed after it expires. You may find discounted options are available by purchasing a home warranty in 3- or 5-year intervals.

How Much Do Home Warranties Cost?

The cost of a home warranty contract will depend mainly on the provider and the type of coverage you choose. On average, purchasing a basic package generally starts around $300 a year. For more comprehensive care, you should expect to pay about $600 for a warranty that includes up to $20,000 worth of protection.

How Much Do Service Fees Cost?

Policyholders are also responsible for a service fee, or a deductible, which is paid to a technician once they arrive on the scene to diagnose the malfunctioning system or appliance. Throughout the industry, these fees generally range between $75–$125 per issue.
