Does anyone have a good home warranty recommendation?

I know they're mostly looked at as useless but we have some leftover seller credits that can be used for a year or two of a home warrenty so we're just going to go for it (it's either that or buy down our rate but the amount of credits we have won't do anything significant to our rate). Our realtor mentioned trying to find one that will do full hvac replacement since ours is a bit older.
