Why Would a Central AC Unit Blow Cold Air OUTSIDE and Room Temperature Air Inside?
A central AC unit blowing cold air outside and room temperature air inside can be a frustrating issue. Fortunately, there are a few common reasons why this might happen, and they often have simple solutions:
- Reverse Valve Problem: The reversing valve is responsible for changing the flow of refrigerant between the indoor and outdoor units. When this valve malfunctions, it can send cold refrigerant to the outside unit and warm refrigerant to the inside unit.
- Refrigerant Leak: A refrigerant leak can cause a drop in pressure in the system, which can lead to decreased cooling efficiency. As a result, the unit may not be able to cool the indoor air properly, even though it is blowing cold air outside.
- Dirty Evaporator Coil: The evaporator coil is part of the indoor unit that absorbs heat from the air. If this coil becomes dirty, it can restrict airflow and reduce the unit's ability to cool the air.
- Blocked Condenser Coil: The condenser coil is part of the outdoor unit that releases heat into the air. If this coil becomes blocked, it can prevent the unit from releasing heat effectively, which can cause the system to overheat and blow warm air inside.
- Electrical Faults: Electrical faults can also cause the AC unit to malfunction and blow cold air outside. These faults can occur in the wiring, the thermostat, or the circuit breaker.
