What to expect from an AC Is Not Working diagnosis at a repair shop

What will be the outcome of an air conditioning system diagnosis?
Replacement of most air conditioning components requires complete evacuation of the air conditioning system with a refrigerant recovery machine. Once components are re-installed, the technician will remove all air from the system in preparation for recharging the system with new refrigerant.
RepairPal Recommendations for air conditioning systems
Refrigerant is environmentally harmful, and should never be released into the air. Instead, a proper refrigerant recovery machine must be used to protect the technician, and the environment. We do not recommend attempting to recharge the A/C system at home, as products available to consumers tend to contain substances that can cause damage to expensive refrigerant recovery equipment. Lastly, if your vehicle has not been converted from R12 to R134a refrigerant, the best time to have this service completed is when the air conditioning system is already being serviced.
What to look out for with the air conditioning system
Refrigerant is a dangerous chemical that can cause severe chemical burns to the skin and eyes if improperly handled, and discharging into the atmosphere will cause damage to the ozone. Refrigerant types are updated over time, and the appropriate type must be used. If there has been an update or conversion from an older refrigerant type, a label should be placed under the hood to make your technician aware of the change. Depending on location, it may be illegal for a technician to replace refrigerant without updating the A/C system to handle the newest type.
Land Rover Range Rover AC Is Not Working Repair Symptoms

AC Recharge
You may not realize there’s a refrigerant leak until the air conditioner stops blowing cold. Refrigerant may slowly leak out of the system over days, weeks or even years.
AC Compressor Replacement
When the compressor fails, the most common symptom is warm air from the vents. A squealing or grinding noise may also be heard from the compressor in the event of mechanical failure.
AC Condenser Replacement
When the condenser fails, the air conditioner will fail along with it. The engine idle speed will not undulate as normal when the air conditioner is turned on, and the air in the vehicle will be just warmer than ambient temperature.
AC Evaporator Replacement
Anytime the AC evaporator goes bad, the air from the vents will be warmer than expected. This is because a clogged or leaking evaporator won’t get enough refrigerant to cool the air.
In some vehicles, there may be some type of warning like a blinking AC switch.
Heater Blower Motor Replacement
When the blower motor fails, the air conditioner and heater may still work, and heat or cool may be felt at the vents, but the air pressure will be dramatically decreased. This will occur at all fan speeds, and all temperatures.
Another possible symptom of failure is a rattling or grinding noise that comes from the passenger floorboard anytime the heater or A/C is active. This can be caused by broken fan blades, or a faulty bearing. This noise may come and go at random, and the fan speed may or may not change the noise.
