Home warranties are billed as helping you avoid unexpected and expensive repairs, but there are some things to consider before buying a policy. One of the benefits of having a home warranty is it gives you peace of mind if something like an old air conditioner needs replacing. But, many times homeowners find what they thought was covered may not actually be covered by their policy. It's highly advised those details are known prior to committing to anything. Things like outdoor appliances may not be covered and homeowners don't usually get to choose who does the repair when something breaks down.
