#2 Best for Aging Homes: Choice Home Warranty

Choice Home Warranty is our top pick for homeowners with aging homes. Unlike many of its competitors, Choice doesn’t deny coverage based on the age of systems or appliances. And even though the company has only been in business since 2008, it already provides warranties in 48 out of 50 states (excluding California and Oklahoma). As with most home warranties, service begins 30 days after the plan purchase.

We recommend Choice Home Warranty because they offer inclusive warranties at low prices, while ranking as one of the best warranty companies in terms of customer satisfaction. Choice Home Warranty is currently not BBB-accredited, receiving a rating of B-. Despite this, it has received countless positive reviews on Trustpilot and Consumer Affairs.

Final Thoughts 

Whether you’ve been considering a home warranty for a long time or you’ve just begun to learn, we hope this article is a helpful guide during your search. Our recommendation is that every homeowner reaches out to several home warranty providers to get free quotes using their own information to ensure the most accurate pricing information.
While American Home Shield scored as our top overall provider, we recommend each of these companies for different situations.

What is a home warranty? 

A home warranty is a residential service contract that covers the cost of the maintenance, repairs, or replacements of most systems and appliances in your home for a set period, usually one year. It is different from homeowners insurance, which can cover the loss of your home and belongings due to fire or certain other natural disasters.

A home warranty helps to grant you peace of mind, knowing that your systems and appliances are covered not just in case of an emergency, but also from daily wear and tear.

Policies are set up so that you can make monthly or yearly payments towards your premium. If something breaks and you need to have someone come take a look, you will be charged a service fee for the visit. Most companies offer unlimited visits, though some companies may have a limit on how much they are willing to pay. Make sure to read your service contract carefully.

What’s covered by a home warranty? 

Each home warranty plan will feature slightly different coverage, but here are some items that you can expect to see offered by most companies:

  • Air conditioning
  • Heating
  • Electrical
  • Plumbing
  • Microwave
  • Dishwasher
  • Refrigerator 
  • Washing machine
  • Dryer
  • Oven
  • Range
  • Cooktop
  • Garbage disposal

Are home warranties worth the cost? 

The cost of a home warranty comes down to a small cost now or the possibility of a larger cost later. While insuring your systems and appliances can cost a few hundred dollars each year, a warranty can protect you from paying even larger sums out of pocket for possible repairs. That being said, it’s possible you could pay for the warranty and then not need it if none of your appliances break.

In essence, home warranty coverage is worth the cost if you desire the peace of mind of not having to worry about the costs of home appliances and systems breaking down.

Do home warranties cover old HVAC? 

It depends on a lot of different variables, the biggest one being who your home warranty provider is and what plan you have with them. Generally, only the more expensive plans will include HVAC Systems, as they are very expensive to replace. 

Also, make sure you look over the fine print of your contract, because some home warranty companies will not cover items that have not been properly maintained. The question of what constitutes proper maintenance has caused many disagreements between home warranty companies and warranty holders filing a claim. So even if your plan covers HVACs, make sure to follow the recommended protocol of renewing filters and other maintenance.

#6 How much does a home warranty cost? 

There is no single answer to this question, as the cost of a home warranty depends on several factors. These include the level of coverage you choose, taking into account the initial cost, any additional coverage, service fees, and possible other expenses. Aspects such as the type, age, and size of the house can also affect the cost. 

An average annual cost can range from $350 to $600 or more, depending on what the plan covers, whether only major appliances or also larger systems such as HVAC, plumbing, and electrical are covered.
