If there is a burning smell, repeated shutdowns, or signs of an electrical issue, it is safer to stop the system and have it inspected. For heating concerns, problems may involve ignition, safety controls, blower performance, or thermostat communication. Routine hvac maintenance and repair planning can include seasonal hvac tune-up visits that catch wear early and improve performance.
