HVAC Troubleshooting Medium Safety

Why’s my heater not working?

If your heater isn’t working, first check the thermostat settings and ensure it’s set to ‘heat’. Make sure the thermostat has power. Also, check for any tripped breakers or blown fuses. If you haven’t changed the filter in a while, change the filter. If it still won’t work, it might be time to call a technician.
