Noises From The Compressor:
If your Air conditioning is overcharged, the compressors need to work significantly harder to push all coolants through the systems pipes.
Keep in mind that your air conditioner functions by compressing a liquid and then releasing it as a gas, which is then converted again to a drink. If your Compressor is overloaded, it cant decompress from liquid to gas. Thus it squirts out refrigerant rather than gas coolant.

How Does Your Cars Ac System Work
Before we answer the question what is an AC recharge, lets briefly describe how electric air conditioning works.
An auto air conditioning unit is a closed-loop system. This simply means that there is no starting point or ending point. The refrigerant goes around and around. If your system has no leaks, it works great. The refrigerant doesnt need to be topped-off.
Car air conditioning systems contain these five parts: a compressor, a condenser, a thermal expansion valve, an evaporator, and an accumulator .
How To Make Ac Colder In Car
There isnt any modification you can do to make your AC colder. The best you can do is maintain the system, clean the condenser, and service as necessary. We do have a small tip: turn off the air recirculation feature when you first turn the AC on and turn it on after about 10 minutes. This helps the AC to get cold quicker, especially if the car has been sitting under the sun.

What Is An A/c Recharge In A Car
As mentioned above, an A/C recharge might mean topping off the refrigerant in your vehicle’s air conditioning system. However, the A/C system is a closed loop so when it’s functioning properly, there should be nowhere for the refrigerant to leak from. Instead, the refrigerant follows a constant, recurring path through components like the evaporator, condenser, and compressor to cool your car.
Your A/c Is Blowing Warm Air
One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air. As we discussed, the air conditioning system in your vehicle operates by circulating this pressurized refrigerant. When the amount drops too low, it eventually affects performance.

The Ac Does Not Cool The Car At All
The most obvious sign that a cars air conditioner isnt operating properly is that it stops cooling the air temperature down in the vehicle. If you are no longer receiving cool air, even if you already set the climate control in your car to the lowest degree, then it is a sure indication that your AC system will need recharging.
On the other hand, a clogged cabin air filter can also result in the loss of AC cooling, and therefore, it is always advisable to inspect the cabin filter first, before recharging the AC.
Why Is My Ac Blowing Warm Air In My Car
A car A/C blowing hot air is often the result of a refrigerant leak. Refrigerant is a liquid that circulates through your cars 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.

Overtime These Pressurized Systems Begin To Leak
As with any mechanical system, time is an enemy. As leaks begin to develop in the air conditioning system, the refrigerant and/or the pressure levels of the system begins to drop. The performance of your car’s air conditioning system will consequently weaken until it fails altogether. Leaks not only affect your vehicle’s A/C, but it also would reduce your gas mileage by forcing your air conditioner to work harder!
Your Car Is Blowing Warm Or Hot Air Instead Of Cold
Perhaps the easiest way to identify an issue with your air conditioner is if your vehicle is blowing warm or hot air. If your vehicle is too low on refrigerant, the evaporator core will not reach the optimal temperature for cooling. The air may start out cold, then blow warm. Or, it may never cool down at all. Either way, it’s time to schedule an A/C Performance Check.

Heres How The Ac System Of A Car Works In Better Detail:
The system uses a special refrigerant gas R134a and is divided into the high-pressure side and the low-pressure side.
High-Pressure Side
Low-pressure R134a refrigerant vapor enters the compressor and gets compressed into high pressure and high-temperature R134a vapor. The vapor that also contains special lubricant oil is circulated into the condenser . As the high temperature and high-pressure vapor travels through the condenser, the heat is released into the much cooler ambient air. While the vapor is cooling down and passing through the condenser tubes, it condenses into a liquid . This high temperature and high-pressure liquid travels through the filter drier and onto the small orifice of the expansion valve. This valve provides a restriction against which the compressor pushes.
Low-Pressure Side
When the liquid refrigerant passes through the expansion valve, its pressure lowers and so does its temperature. Now its a low pressure and low-temperature vapor. Next, the refrigerant passes through the evaporator. The hot air of the cabin is being blown through the evaporator, thus cooling the air of the cabin down. Then, the R134a refrigerant is pulled back into the compressor and the cycle begins again.
