Why does my AC line freeze up?
The main reason why your AC lines are freezing is because your evaporator coils are getting too cold. The evaporator coil is filled with refrigerant which cools the air in your HVAC system. The ice can eventually accumulate on the refrigerant line.
What should I do if my AC unit is frozen?
In many cases, you may be able to defrost the ac unit yourself. You should avoid running the air conditioner if you think you have a frozen evaporator coil because this can place a strain on the compressor which could possibly cause damage and burn it out.
How do you remove a clutch from an AC compressor?

What happens when the AC clutch does not work?
An automobile can have numerous serious problems and a dysfunctional AC compressor clutch is one of them. When this component does not work properly, the engine does not get the cold air flow – leading to some major complications. Knowing how to manually engage AC compressor clutch will help you skip a visit to the mechanic.
How do you install a new AC clutch?
Insert the new pulley, and engage the snap-ring with the beveled edge facing outward. Install one spacer on the compressor shaft, then install the clutch, and fasten the 6 mm bolt securely. Place the feeler gauge between the clutch and the pulley to ensure proper clearance.
