For issues related to natural gas appliances, customers typically need to contact a licensed plumber or HVAC technician who is experienced in handling and servicing these appliances. It is also a good idea to consult the manufacturer's guidelines for your specific appliances, as they may offer recommendations for maintenance and service.
