There’s nothing worse than turning on your car’s A/C on a hot day, only to feel warm air blowing in your face. If your air conditioner is running but only blowing hot air, something isn’t working right. Here are a few common reasons why such an event might be happening: These issues include low refrigerant, a faulty compressor, electrical problems, a clogged or broken condenser, or a malfunctioning blend door.
Refrigerant is the chemical that cools the air in your A/C system. If it’s low (usually due to a leak), your A/C can’t function properly and will blow warm or hot air instead.
You may also hear a hissing noise or notice that the A/C takes longer to cool, if it cools at all.
The compressor is the heart of the air conditioning (A/C) system. It keeps the refrigerant moving. If it fails or isn’t engaging, your A/C won’t cool the air like it should.
You may notice a clicking sound when the A/C is on or no noticeable change in air temperature.
Blown fuses, faulty wiring, or a bad relay can all prevent your A/C from working correctly. Even if everything else is fine, an electrical problem can shut it down.
The condenser’s job is to cool the refrigerant after it’s been compressed. If it’s blocked by debris or damaged, the system can’t release heat, and the air stays warm.
Inside your car’s ventilation system is a component called a blend door that controls airflow from the heater and air conditioner. If it gets stuck or breaks, it may only allow hot air to pass through.
If your air conditioner is blowing hot air, you should take your car to a professional auto repair shop. A certified technician can run a quick diagnostic check to find the exact cause and get your A/C working again, just in time for the summer heat.
