How Does a Home Warranty Work?

A home warranty is a protection plan that assists Wheaton homeowners reduce the costs of appliance and system repairs. The plans offer coverage to repair or replace appliances and systems that stop working due to normal wear and tear.

When something breaks down, you submit a claim and pay a service fee. The home warranty provider then finds a contractor to handle the repair or replacement. Homeowners may have out-of-pocket costs only if the repair or replacement goes over the item's coverage limit. A home warranty gives reassurance to homeowners, as it helps prevent costly emergency repairs. Home warranties are especially useful for older construction homes with aging systems. New homes with modern appliances might not require a home warranty.

What Does a Home Warranty Cover?

Home warranties cover your home systems and appliances. Common appliances covered include refrigerators, garbage disposals, dryers, washers, microwaves, dishwashers, and more. Covered systems are typically plumbing, air conditioning, electrical, and heating. Many home warranty companies provide add-on coverage for septic systems, locksmiths, roof leaks, and central vacuums. Wheaton should understand that most home warranty plans have a 30-day waiting period before repairs are covered. Most policies also only cover repairs and replacements due to normal wear and tear. Home warranties don't include natural disasters, pre-existing conditions, cosmetic issues, or misuse of a system or appliance. Stay current with preventative maintenance to help guarantee your next repair or replacement is covered.

Key Home Warranty Terms to Know

Here are some essential home warranty terms to learn before signing a contract:

  • Trade call fee: An added fee that you'll sometimes need to pay for appliance-related claims.
  • Endorsements: Optional add-ons that expand coverage for additional systems like pools, well pumps, septic, and more. Endorsements typically cost an additional fee.
  • Coverage limits: Dollar limits that cap how much the warranty will pay for certain repairs or replacements. Check limits on appliances, roof leaks, air conditioning units, and similar repairs.
  • Contract rate: The rate that your home warranty provider has pre-negotiated with its contractors. Normally, this rate is lower than what you'd pay retail.
  • Claim approval: The process providers use to determine whether a requested repair or replacement is covered under a home warranty plan.
  • Deductible: How much you pay for a covered repair before your warranty covers the rest. Deductibles can be per-claim or yearly.
  • Service fee: The amount you pay our of pocket per claim for access to a contractor and repair coverage.
Keeping these important details in mind will help you understand costs and select a home warranty that's tailored to protect your home. Discuss specifics of coverage with potential providers during the quote process, so you can avoid unexpected fees.

Key Factors in Choosing a Home Warranty Company

When you're deciding on a home warranty provider, there are several key things to take into account:

Coverage Options

Home warranty policies can have major differences in covered items. Most plans cover AC, heating, electrical, plumbing, and appliances. More comprehensive options also include coverage for other items such as pools, spas, roof leaks, and well pumps. Look for companies with an assortment of coverage options, such as upgraded plans. Flexibility helps you tailor your protection for your home’s needs.

Service Fees

With any home warranty claim, you'll pay a repair fee that typically ranges between $60 and $100, which gets paid per claim you submit. The per-request costs can add up. You may decide to look for companies with lower service fees to maximize your savings on each claim. Some firms also offer disappearing deductibles for customers who don't file any claims over a certain timespan.

Reputation

A home warranty company's reputation gives you insight into things such as contractor quality, claim approval rates, timeliness of repairs, and overall customer satisfaction. Use third-party review sites such as TrustPilot, the Better Business Bureau (BBB), or Google Reviews to research providers. Favorable ratings and reviews indicate a company known for stellar service.

Contractor Network

Home warranty providers maintain networks of professionals to handle covered repairs. Bigger networks raise the probability of getting qualified technicians to quickly service your home. Ask potential providers how many contractors they have in Wheaton to get a sense of how soon your repairs could happen in an emergency.

Added Benefits

Certain home warranty companies offer extras such as discounts on maintenance, energy-efficient upgrades, and protection for smart home devices. These provide extra value beyond repair coverage. Extra perks enhance your home and help maximize your home warranty.

Is a Home Warranty Worth it in Wheaton?


Benefits of a Home Warranty

Home warranty policies are an inexpensive way to guard your home systems and appliances from normal wear and tear. With temperatures in Wheaton reaching an average high of 63℃F, you may find that certain appliances, like your air conditioner, get a lot of use. A home warranty can remarkably bring down out-of-pocket expenses should your HVAC system stop working.

Not only can a home warranty save you money on repairs and replacements, it saves you time as well. Instead of having to vet service technicians on your own, home warranty providers do the work for you and send a contractor from their network right to your door when you need them. A home warranty can also give value in other ways. For example, some plans can be transferred to another owner during a home sale.

Downsides of a Home Warranty

There are also some negatives to buying a home warranty plan, such as the coverage exclusions. For example, home warranties may not cover home systems or appliances that already have a manufacturer's warranty.

Another consideration is that home warranties typically only cover malfunctions due to normal wear and tear. They commonly won’t cover home systems or appliances that have been damaged due to improper maintenance, natural disasters, animal infestations, etc.

Frequently Asked Questions About Home Warranty in Wheaton, MD

A home warranty in Wheaton can cost between $30 and $60 a month. The higher-priced plans usually have higher coverage limits, broader coverage, and a lower service fee. You can often lower this cost by paying annually instead of monthly. Some providers will also lower your up-front costs when you agree to a higher service fee.

Home warranties and home insurance differ in what types of damage they cover. Home warranty policies cover problems related to home systems and appliances that need to be repaired or replaced due to normal wear and tear. A home insurance policy is a larger plan that protects an entire home from natural disasters, which might not be too much of a concern in Wheaton. It doesn't cover a normal appliance or system breakage.

First-time homebuyers, home sellers, landlords, homeowners, and real estate agents can all get home warranty plans. A home warranty can help make your property more appealing to prospective buyers and save you money in the long run.

The different types of home warranties in Wheaton include plans with coverage for either appliances or systems as well as comprehensive plans. A comprehensive plan will cover many of your systems and appliances, such as your dishwasher, washing machine, and HVAC. A plan that only covers appliances or systems will cover only the specific items mentioned in the policy.

Generally, a home warranty offers coverage for a year and can be renewed annually. Some companies may offer month-to-month plans.

Usually the one who owns the home pays for the home warranty. In some cases, though, the home seller may purchase a home warranty and transfer the policy to the buyer. The new homeowner will then be responsible for the service fees when using the policy. Since the average home value in Wheaton is $852,466, a home warranty can be an added asset when buying a home.
