Heater not working

in Gas Heating
We have a brand new home with brand new hvac unit. The heater will not blow hot air. Have no issues with the ac. We've done the following trouble shooting:
- unit has a brand new filter
- Pilot-less unit and it is running. Not pilot issue or breaker issue
- Gas to unit is on position
- Thermostat is set to heat and fan auto
- When fan set to on, it does blow cold air. Not duct blockage
Not sure what else we can try. The home has two units and the other one is working just fine in heat mode.
