What it can look like at home
A propane heating system depends on a safe fuel supply, properly operating appliance, controls, venting, and the distribution system that carries heat through the home. A no-heat symptom may look similar to another fuel system even though the service context is different.
Why it can happen
A propane heating problem can involve the appliance, fuel level, tank regulator, supply piping, ignition, venting, controls, or combustion process. Do not try to adjust gas components. A persistent odor, hissing, or suspected leak requires leaving the area and following the provider or emergency instructions.
