Why does my car AC make a loud noise when it turns off?
If this happens after you turn the vehicle off, this isn’t a bad sign—it’s a result of pressure equalization as the refrigerant moves from the high-pressure side of the compressor to the low-pressure side. There’s no need to worry about this sound.

Why does my car air conditioner compressor turn on and off?
The car has several thermostats, one on the evaporator coil to make sure it isn’t supercooled and it switches the actual compressor on and off as needed to get as much cooling as needed. This is independent of the fan speed which is bring the cabin ari to the evaporator to cool the air off.
How much does it cost to replace an AC compressor?
According to data by HomeGuide, the average cost to replace a home air conditioner compressor is about $600 to $1,200 under warranty, or $1,300 to $2,500 when it’s not under warranty. Many HVAC contractors charge $100 to $150 per hour plus the cost of parts to repair a home AC compressor.
Can a bad compressor cause a Freon leak?
Dirty or clogged coils can cause water leaks around the air conditioner. However, a bad compressor can also leak refrigerant. Refrigerant contains Freon and is not a substance that people should come into contact with. When in doubt, call an AC repair professional to come to inspect your unit.
Can low refrigerant damage compressor?
Low refrigerant also damages the compressor, the “heart” of the air conditioner where the liquid refrigerant is squeezed into a high pressure gas. The compressor is designed to match the refrigerant charge, and if it drops, the compressor will start to overwork and will soon break.
Can low refrigerant cause noise?
Often gurgling sounds in the refrigerant piping are a telltale of low refrigerant or a TEV malfunction – gas bubbles in the liquid line, for example.
How do I know if my AC compressor fuse is bad?
Test the load: If you saw a voltage reading during the previous step, run the same test on the “load” side of the fuses. You should again see a reading between 220 and 240. If you see a voltage reading on the “line” side but not the “load” side, it means you have a blown fuse.
