Air Conditioner Heat Mode Not Working (Fixed)
If your air conditioner’s heat mode isn’t working, it can be frustrating, especially during colder months. Understanding the reasons behind this issue can help you troubleshoot effectively.
Air Conditioner Heat Mode Not Working, In this article, we’ll explore common causes and solutions for when your air conditioner heat mode is not functioning properly.
Why Is My Air Conditioner Heat Mode Not Working?
When your air conditioner is stuck in cooling mode or fails to produce heat, several factors could be at play. Let’s delve into the most common reasons behind the malfunction.
1. Thermostat Issues
The thermostat is the brain of your HVAC system, controlling the temperature and switching between modes. If it’s malfunctioning or incorrectly set, it can prevent your air conditioner from entering heat mode.
- Check the Settings: Make sure the thermostat is set to “Heat” and the temperature is higher than the current room temperature.
- Calibration Issues: Sometimes, the thermostat may need recalibrating. If it’s not reading the temperature accurately, it won’t switch to heat mode.
2. Dirty Filters
A clogged or dirty air filter can restrict airflow, leading to inadequate heating.
- Regular Maintenance: Change your air filters every one to three months to ensure optimal airflow and efficiency.
- Check for Blockages: Inspect the filter and surrounding areas for dust and debris that might be obstructing airflow.
Troubleshooting Your Air Conditioner Heat Mode
If you’ve identified that your thermostat and filters are in good condition, here are some additional troubleshooting steps you can take.
1. Inspect the Circuit Breaker
Sometimes, the issue may stem from a tripped circuit breaker.
- Reset the Breaker: Locate your breaker panel and check if the circuit for your air conditioning unit has tripped. If it has, reset it and see if that resolves the issue.
2. Examine the Heat Pump
If you have a heat pump system, it’s essential to ensure it’s functioning correctly.
- Check for Ice Buildup: Inspect the outdoor unit for ice accumulation, which can hinder its ability to provide heat. If you find ice, turn off the system and allow it to thaw.
- Listen for Unusual Noises: Unusual sounds from the heat pump may indicate a mechanical problem.
When to Call a Professional
If you’ve tried the above steps and your air conditioner heat mode is still not working, it may be time to call in the experts. A professional HVAC technician can diagnose more complex issues such as:
- Refrigerant leaks
- Electrical problems
- Malfunctioning components like the compressor or reversing valve

Thermostat Settings: The thermostat may be set to “Cool” instead of “Heat.” Ensure it’s properly adjusted.
Dirty Filters: Clogged filters can restrict airflow and prevent proper heating. Check and replace them if needed.
Refrigerant Issues: Low refrigerant levels can affect the heat pump’s ability to generate heat. This requires a professional inspection.
Heat Pump Malfunction: If you have a heat pump, it could be stuck in cooling mode due to a faulty reversing valve.
Electrical Problems: Faulty wiring or malfunctioning components can prevent heating.
How do I reset my AC heater?
To reset your AC heater, follow these simple steps:
Turn Off the System: Set your thermostat to “Off” or switch the AC heater off at the circuit breaker.
Unplug (if applicable): If your unit is portable or window-mounted, unplug it from the power source.
Wait a Few Minutes: Leave the system off for about 5 minutes to allow it to reset fully.
Restart the System: Turn the thermostat back on or plug the unit back in, then set it to “Heat” mode.
Check the Settings: Ensure the temperature is set higher than the current room temperature.
Why is my HVAC not turning on the heat?
If your HVAC system isn’t turning on heat, consider these common issues:
Thermostat Settings: Ensure the thermostat is set to “Heat” and the desired temperature is higher than the current room temperature.
Power Issues: Check if the system is receiving power. Look for tripped circuit breakers or blown fuses.
Dirty Filters: Clogged air filters can restrict airflow. Replace or clean the filters to improve performance.
Pilot Light or Ignition Problems: For gas furnaces, check if the pilot light is lit or if there are ignition issues.
Faulty Components: Issues with the blower motor, limit switch, or other internal components may prevent heating.
