## First, separate danger from a comfort problem

If there is no sign of an emergency, a loss of heat still deserves prompt attention—especially in freezing weather or when someone in the home is vulnerable to cold. If the home cannot remain safely warm, arrange a safe warm place to stay while seeking qualified help.



## Gather observations, not a diagnosis


- Note whether all rooms or only one area has lost heat.
- Read the thermostat’s normal display and note any message.
- Record when the change began and whether it is intermittent.
- Share the equipment type if known; a description is enough if you are unsure.
- Leave panels, wiring, fuel connections, and safety controls to the professional.
