When the heat quits, start with the simplest checks: thermostat settings, an accessible air filter, and whether the system is running at all. If the home is getting colder or the same problem returns, have a professional diagnose it.
What should I check first?
Set the thermostat to heat and above the current room temperature. If it uses batteries, check them. Look at the air filter if you can reach it safely. Make sure vents are not blocked by furniture or rugs. Note any error message or unusual sound so you can describe it when you call.
Why does the heater run but the house stays cold?
The fan can run without the system delivering enough heat. Restricted airflow, thermostat issues, or a problem within the heating equipment could be involved. Different systems work differently, so a technician needs to identify the actual cause before recommending a repair.
What if the breaker has tripped?
A tripped breaker may signal an electrical problem. Do not keep resetting it if it trips again. Call for service and mention the repeated trip. Avoid opening equipment panels or attempting electrical or gas repairs yourself.
When is no heat urgent?
If the indoor temperature is dropping rapidly, vulnerable people are in the home, or you notice a gas smell or a carbon monoxide alarm, act promptly. For a suspected gas leak, leave the area and contact the gas utility or emergency services from a safe location. For a carbon monoxide alarm, get everyone outside and call emergency services. Do not wait for an article or a service appointment in those situations.
