3 Signs That Your Car's Air Conditioner Needs Freon
March 23, 2022at12:00 AM
It's all about the pressure
Air conditioning systems leverage high-and-low pressure. Before the Freon is converted into a liquid in the high side, it starts out as a gas in the low pressure side of the system. The vehicle is kept cool by the constant circulation of refrigerant through the high and low pressure sides of the system.
1.Blowing Warm Air
One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air. As we discussed, the air conditioning system in your vehicle operates by circulating this pressurized refrigerant. When the amount drops too low, it eventually affects performance.
2. Listen For The A/C Clutch to Engage
When you turn on your vehicle's air conditioner, if you listen closely, you will hear a 'click' which signifies the clutch engaging. If the Freon levels are too low, the clutch will fail to engage which means there's not enough refrigerant for the compressor to pressurize. In other words, your air conditioning system has nothing to work with!
3. Visible Refrigerant Leaks
Another more serious symptom of low Freon levels is visible leaking. If you notice a leak, you will know it's Freon if it appears as a 'thin' greasy substance. These leaks often appear under the hood around the compressor, inside the cabin, or leaking under your vehicle. If you notice leaking, you should head over to Nate's Garage and have an ASE-Certified technician diagnose the issue and take care of your vehicle's A/C issues.
