Best Home Warranty type companies?

[Kirsten Ostby]

I have a SFH rental in North Carolina and I'm looking into getting some type of home warranty plan for the appliances and HVAC systems. Does anyone have a company they recommend? I would prefer one that doesn't charge for service calls. I currently use HomeSmart by Xcel Energy on my Minnesota SFH rental, and I like their service. But they are not available in NC. For $35/month all of the appliances are covered for minor repairs, no charge for service calls, and appliance replacement coverage with a small deductible. I really don't want to pay for service calls because it seems like most of the time they are for little things that the tenants are neglecting (not cleaning filters, etc). I appreciate any input!
