Can I recharge my AC without vacuum?

Charging your air conditioner without a pump is possible! Follow these steps to get it done: Relieve the pressure in the air conditioner system’s access valves. Turn the low-pressure side of the air conditioner to 14 psi.

What happens if you charge AC without vacuum?

KOG. What will happen if you don't evacuate moisture is that the acids formed by high temperature reaction of refrigerant and moisture will destroy the condenser, the evaporator, the compressor and any control valves in the system as well as any aluminum lines. In other words, every part of the entire system.

Do you need to vacuum AC system before adding Freon?

So, if you were wondering whether it's that important to vacuum your AC system, the answer is, yes! Vacuuming allows you to remove any moisture and air from the system, guaranteeing optimal performance.

Should I add oil when replacing AC condenser?

When replacing a part like the condenser it is a good idea to add some extra oil with the new refrigerant. Most refrigerants do have some oil in them which should be enough. The majority of the oil in the system stays in the compressor so you should not have any issues if you do not add any more.

Does vacuum remove PAG oil?

Now that I’ve learned that the vacuum typically will not remove the PAG oil, I have a better understanding of what is going on.

How much oil does a condenser take?

The total system oil capacity for many late model passenger car A/C systems is only about 4 ounces (120 ml). A low oil level can starve the compressor for oil and lead to compressor failure. CAUTION: Do NOT overfill the the A/C system with too much compressor oil.

Why is my AC not cold after recharge?

If your car A/C not blowing cold air consistently, the first thing to check is the refrigerant level. The refrigerant is the fluid that passes around the entire A/C system. It can evaporate at lower temperatures and condense into liquid form when exposed to high pressure. The A/C in your vehicle is a sealed system.

Why is my car AC blowing warm air?

A car A/C blowing hot air is often the result of a refrigerant leak. Refrigerant is a liquid that circulates through your car’s A/C system, expanding and contracting as it removes heat and humidity from the cabin. None of the other A/C components will function correctly without proper refrigerant levels.
