Maybe, if your home warranty actually has competent providers in its network. When I had one, it was always pulling teeth to get a provider to come out; and most of the providers who are willing to drive 3-4 hours to come out on a home warranty contract aren't the best. And yes, they did replace some things, but at least for me, I'd rather have paid out of pocket to get things fixed or replaced in a timely manner, rather than f**ing around for 3-5 months to get my air handler replaced or my oven almost replaced and then just get a check because their selected oven didn't actually fit. Of course, the check didn't really cover an oven that would fit; but maybe if you have a less fancy house their part selection would work out.
