Why Is My Car AC Blowing Hot Air?

Before you learn how to car AC not blowing cold air, it’s essential to understand why your car’s AC is malfunctioning. Several factors could be responsible:

• Low Refrigerant Levels: One of the most common reasons for hot air blowing from your car’s AC is low refrigerant levels. Refrigerant, also known as coolant, is essential for cooling the air before it enters your car’s cabin.
• Refrigerant Leaks: Even if your AC started the season with an adequate refrigerant charge, leaks can occur over time. These leaks can lead to a drop in refrigerant levels, resulting in warm air blowing from the vents.
• Faulty Compressor: The AC compressor is responsible for pressurizing the refrigerant and circulating it through the system. If the compressor fails, the AC system won’t function correctly.
• Clogged Expansion Valve or Orifice Tube: The expansion valve or orifice tube regulates the flow of refrigerant. If they become clogged or blocked, it can hinder the cooling process.
