How do I know if my car AC condenser is clogged?

With a clogged condenser, you will notice higher pressures even though you have the right amount of refrigerant in the system. These higher pressures are noticed on both the high and low side. Condensers are subject to clogs because of the leftover particles in the refrigerant.

Why is my car AC running but not cooling?

The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

How do I know if my car AC evaporator is bad?

A broken air conditioner may be a result of a faulty AC evaporator….4 Symptoms of a Bad or Failing Air Conditioning Evaporator

1. The cool air is weak or no cold air is blowing at all.
2. You notice a strange odor when using your AC system.
3. The AC compressor will not activate.
4. The AC temperature will vary.

How do you test an AC evaporator?

To verify if a leak exists, before removing the evaporator, a vacuum test can be performed. Using appropriate flush adapters on the evaporator fittings, pull a vacuum of 28” to 30” Hg. The evaporator should hold vacuum for 30 minutes. If there is a loss of vacuum, verify that the adapters and gauges are not the cause.

How do I fix my AC from blowing hot air?

If your AC is blowing hot air, the thermostat may have been accidentally set to “heat.” If this is the case, it’s easy to fix on your own. Simply flip the thermostat setting back to “cool” and see if the air conditioner begins to blow cool air again.

Is there a fuse that controls the AC compressor?

Air conditioner fuses protect the condenser from being exposed to excessive amperage. Fuses are designed to handle a limited amount of amperage based on the maximum amount the unit is rated for: If more amperage passes through, the fuse will blow to protect the condenser from overheating.
