If your heat is running but not heating your home, several issues could be the cause. Start by checking your thermostat settings to ensure they're correct. Next, inspect your furnace filter; a clogged filter can restrict airflow, causing the system to run without properly heating. Also, verify that all vents are open and not obstructed. If these steps don't resolve the issue, it could indicate a more serious problem, such as a malfunctioning heating element or a problem with the furnace itself. In such cases, contacting a professional HVAC technician is advisable.
