A/C blowing warm air
Hissing noise near the dashboard o r engine bay
Ice buildup on A/C pipes
Frequent cycling of the compressor
A low refrigerant level usually means there is a leak. It’s important to fix leaks before recharging refrigerant, o r the problem will return.

Low refrigerant, also known as A/C gas, is a common cause of A/C issues. Symptoms of low refrigerant in your Toyota Camry include warm air blowing from the A/C vents, which is a direct result of insufficient refrigerant to cool the air. You may also hear a hissing noise from the dashboard o r engine bay, which often indicates a refrigerant leak. Another sign of low refrigerant is the formation of ice buildup on A/C pipes, which occurs when the system is not functioning properly due to low refrigerant. The compressor may also cycle frequently due to the lack of refrigerant. If these symptoms occur, it’s important to fix any leaks before recharging the refrigerant, as leaks can cause the problem to recur.
