Your air conditioner might be running outside but not inside for several reasons, often related to the indoor unit, also known as the air handler.
Potential Causes
According to reference #1, if the compressor outside your home is running but the air handler isn't, you might be cooling air that isn't going anywhere. Here's a breakdown of the possible causes:
- Air Handler Issues: The air handler is the indoor component that circulates the cooled air. If it's not running, no cool air will be distributed inside.
- Power Problems: The air handler might not be receiving power. Check the following:
- Breaker: Ensure the circuit breaker for the air handler hasn't tripped.
- Switch: Look for a switch on or near the unit that might have been accidentally turned off.
- Air handler is turned off: Double-check the thermostat is on and set to cool mode.
If the outdoor unit is running but you're not feeling any cool air inside, investigating the air handler's operation and power supply is the best first step.
