Understanding these common reasons can help you troubleshoot and address the issue of your AC running but not heating effectively.

Check the Thermostat Settings

When your AC is running but not heating, the first step is to Check the Thermostat Settings. Here’s what you need to do:

  • Ensure the thermostat is set to heat mode.
  • Double-check the temperature setting to be higher than the current room temperature.
  • Verify that the fan setting is on auto or on, depending on your preference.
  • If your thermostat is programmable, review the schedule to rule out any conflicts.

By reviewing and adjusting the thermostat settings, you can potentially resolve the issue of your AC running without producing heat.

Inspect the Air Filter

When your AC is running but not heating, a common culprit could be a dirty air filter. A clogged filter can block proper airflow, hindering the heating process.

To address this issue, locate the air filter in your AC system. It’s typically found near the return air duct or blower compartment.

  • Check the filter for dirt, dust, or debris buildup.
  • If the filter looks dirty or clogged, it’s time to replace it with a new one.
  • Refer to your AC’s manual for guidance on the correct filter type and replacement procedures.
  • Regularly changing your air filter, typically every 1-3 months, can improve heating efficiency and overall AC performance.

By inspecting and replacing your air filter as needed, you can help maintain optimal airflow and ensure that your AC functions effectively in heating your home.

Check for Power Supply Issues

If your air conditioner is running but not heating, it’s crucial to Check for Power Supply Issues. Here’s what you can do:

  • Inspect the circuit breaker to ensure it hasn’t tripped.
  • Look for blown fuses in the electrical panel.
  • Verify that the AC unit is receiving power by checking the power switch.
