How your vehicle's air conditioning works.
We all know how hot the Texan heat can be
The Texan heat is tough on air conditioning systems, and during the summer months, the last thing you want is to head out for a long drive only to realize your vehicle's air conditioning is not working. The chemical (refrigerant) used to provide cool air is called Freon. Without it, there's no way to circulate cold air throughout your vehicle cabin.

It's all about the pressure
Air conditioning systems leverage high-and-low pressure. Before the Freon is converted into a liquid in the high side, it starts out as a gas in the low pressure side of the system. The vehicle is kept cool by the constant circulation of refrigerant through the high and low pressure sides of the system.

The vehicle is kept cool by the constant circulation of refrigerant through the high and low pressure sides of the system.
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 (Freon) 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!
Vehicle A/C Freon Recharge
3 Signs Your Vehicle’s A/C Needs To Be Recharged
Car Air Conditioning Blowing Warm Air
1. 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.
2. Listen For The A/C Clutch to Engage
When you turn on your vehicle's air conditioner, if you listen closely, you will hear a 'click' which signifies the clutch engaging. If the Freon levels are too low, the clutch will fail to engage which means there's not enough refrigerant for the compressor to pressurize. In other words, your air conditioning system has nothing to work with!

3. Visible Refrigerant Leaks
Another more serious symptom of low Freon levels is visible leaking. If you notice a leak, you will know it's Freon if it appears as a 'thin' greasy substance. These leaks often appear under the hood around the compressor, inside the cabin, or leaking under your vehicle. If you notice leaking, you should head over to your local auto repair shop and have an ASE-Certified technician diagnose the issue and take care of your vehicle's A/C issues.

What Happens With A Vehicle A/C Recharge?
An ASE-Certified technician would check the system's pressures with gauges, and then identify any possible leaks. If a leak is found, the technician will repair the leak before refilling it with fresh refrigerant. Furthermore, if your vehicle's A/C components have been taken apart or changed, to ensure the longevity of your air conditioning unit, technicians would ensure the system is void of all atmospheric air and moisture before charging it.
