Troubleshoot

1) Check the thermostat: Make sure the thermostat is set to the desired temperature and that it is set to "heat" or "cool" mode. If the thermostat is not working properly, it can prevent the system from turning on.

2) Check the air filter: A dirty air filter can restrict airflow and cause the system to work harder than it needs to, which can lead to malfunctions. Check and replace the air filter if necessary.

3) Check the circuit breaker: If the system is not turning on at all, check the circuit breaker to make sure it hasn't tripped. Reset the breaker if necessary.

4) Check the power supply: Make sure the system is properly connected to a power source and that the power supply is working properly.

5) Check the outdoor unit: If the system is not producing heat or cool air, check the outdoor unit to make sure it is not blocked by debris or obstructed in any way. Clear away any debris or obstructions that may be blocking the unit.

6) Check the ductwork: If the system is not distributing air properly, check the ductwork for any leaks or damage that may be preventing the air from flowing through properly.

7) Contact Greg Boddie Heating and Air: If you have tried all these troubleshooting steps and the system is still not working properly, it may be time to contact a professional HVAC technician who can diagnose and repair any issues with the system.
