Question

How do you check freon levels in your car?

Freon is a crucial component of the AC system that helps cool the air circulating inside the cabin. It is chlorofluorocarbon and, therefore, harmful to the environment. Without Freon, the functioning of the AC system will be tampered with, and the cabin's temperature will start rising rapidly.

Maintaining the correct freon level in your car’s AC system is crucial to ensure optimal performance. 

What are the signs that your car may be low on freon? 

• AC is not very cold.  
• It feels like air coming out of the air conditioner. 
• Clicking noise while turning on the AC is no longer there. 
• Greasy leaks around the compressor or the car’s interior. 
• Frozen water around the compressor.  

How to check the freon level in your car 

• Turn off the engine and let it cool down completely. 
• Check for loose clamps or damaged pieces in the air conditioning system. 
• Locate the high-pressure service port located near the AC compressor. 
• Securely connect the freon gauge to the high-pressure service port. 
• Start the car and set the air conditioning to the coldest temperature.  
• Run the car for a few minutes and recirculate if necessary. 
• Use the thermometer to measure the temperature.  
• Check the gauge readings. For instance, the low port should read 25psi to 45psi, while the high port should read 250psi to 400psi. If both are low, you are most certainly running out of freon. 
• Turn off the engine and disconnect the gauge from the high-pressure service port. 
• Refill the freon if the gauge readings indicate a low freon level.
