The most common cause of an AC system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system.
Simply so, Why is my AC not cold after recharge? Added Freon still not cold
If your car’s AC isn’t blowing cold air it might be low on refrigerant. In most cases you can recharge car AC systems yourself with a can of refrigerant, a charging hose and gauge from any auto parts store.
What happens if you put too much AC recharge? Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.
Subsequently, How long does it take for home AC to get cold after recharge?
A properly functioning central A/C unit should be able to cool a moderate, four-bedroom home by 10 degrees Fahrenheit in three hours. Although the cooling power of your A/C also depends on the power, size, and age of your unit, your home should be noticeable cooler within a few hours.
What happens if you overfill freon in your car?
The potential for the greatest amount of damage, though, is to the compressor. Overcharging the unit can cause permanent failure of the compressor, which is the pump for the refrigerant. Replacing the compressor can actually cost more than replacing the entire outdoor unit.

Can you put too much freon in a car?
As a common side effect, excess freon gas can prevent the compressor from working at its capacity. In some cases, extra freon accumulates inside the compressor and results in subcooling or undercooling. In the worst of cases, the freon gas may even damage the internal mechanism of the compressor.
Does freon go in high or low? The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY’S SAKE.

What if freon does not work? Air blown across metal filled with cold freon causes the air to cool quickly. If your compressor isn’t working, the air won’t get cold. And your compressor might not be working because of low freon levels, an electrical problem, or an overheated engine.

How many cans of Freon does a car hold?
Most newer passenger car A/C systems do not hold much refrigerant (only 14 to 28 oz.), so you don’t want to add too much if the system is low. One can of R-134a typically holds 12 oz. of refrigerant. 11.

Freon (which is really just a particular brand of refrigerant) lasts forever. It’s not like gas in car; it does not get “used up.” You see, your air conditioner’s refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.
Can I put freon in my car myself? You’ve likely run low on refrigerant in your A/C system. Over time, tiny amounts of refrigerant leak from the lines, degrading A/C performance. The solution is simple – put more back in. Recharging your air conditioner yourself is inexpensive and can be completed in just a few minutes.
