Get a protection plan on all your appliances

Did you know if your air conditioner stops working, your homeowner’s insurance won’t cover it? Same with plumbing, electrical issues, appliances, and more. Not being able to make repairs could leave you in a bad situation — but a home warranty could protect you against surprise expenses.

Whether you’re a brand-new homeowner or you’ve owned your home for years, a plan from Choice Home Warranty could pick up the slack where homeowner’s insurance falls short.

If a covered system in your home breaks down, you can call their hotline 24/7 for assistance to get it repaired. They have a network of over 15,000 technicians that can assist you, making sure any issue can be taken care of swiftly — without breaking the bank.

Not sure if it’s for you? Rest easy: they were named one of the "Best Home Warranty Companies" by US News 360 Reviews and were awarded Best Company's 2020 Consumer's Choice Award. For a limited time, you can get your first month free when you sign up for a Single Payment home warranty plan.
