Why is there no heat coming from my new central air unit? AC works fine, but when put to heat, the fan will kick on, but there is no heat.
If your new central air unit is providing cool air but not heat, there are a few potential reasons:
- Incorrect Thermostat Setting: Ensure the thermostat is set to "Heat" mode.
- Malfunctioning Heat Exchanger: The heat exchanger could be blocked or damaged, preventing the transfer of heat.
- Faulty Gas Valve: The gas valve could be malfunctioning, restricting the flow of gas to the furnace.
- Broken Blower Motor: The blower motor may not be functioning, preventing the circulation of warm air.
- Clogged Air Filter: A clogged air filter can restrict airflow, leading to reduced heat output.
