Exceptional service and highly recommended. I am a new home owner and made several calls to other companies for a service appointment for my furnace. SOC was the 3rd company I called and they showed up and fixed my issue before the 2 other companies even called me to schedule an appointment. Someone was at my house within 2 hours, answered all my questions, fixed my issue, and even topped off my oil tank. Thanks, Mike!
