Have you ever experienced your outside AC unit blowing cold air while your indoors remain uncomfortably warm? It can be frustrating and confusing, especially when the weather outside is scorching. The good news is that you’re not alone, and there could be several reasons why your outdoor AC unit is blowing cold air.
One common reason why a heat pump or split AC system is blowing cold air outside is due to a refrigerant leak. This is caused by wear and tear or damage to the copper tubing connecting the outdoor and indoor units. When there’s a leak, the refrigerant will escape and eventually your AC system will stop cooling altogether.
Another possibility is that your AC’s capacitor has failed. The capacitor is responsible for supplying the necessary electrical charge to start the motor that runs the compressor and the condenser fan. When the capacitor fails, your AC system can’t start-up appropriately, and the fan will continue to run, blowing cold air outside.
Sometimes, your AC unit may continue to run, but because of clogged condenser coils or air filters indoors, warm air doesn’t circulate as it should. This can cause the AC unit to think that cooling is not required, making it only blow cold air outside.
Here’s an idea: if your AC system is not cooling, you might be tempted to switch it off and forget about it. However, this may do more harm than good. Turning off the AC when it’s not working could cause the compressor to overheat and can lead to expensive repairs.
We’ve investigated the most common reasons why an outside AC unit blows cold air. Now, let’s dive deeper into each problem and learn how you can troubleshoot a problematic AC system and resolve the issue before calling an HVAC technician.
