Why is My Car Air Conditioner Not Blowing Cold Air?

• Compressor
• Condenser
• Evaporator
• Orifice tube 
• Receiver dryer 

The most typical problem that most car AC repair technicians are faced with are: 

• Coolant: Many cars with air conditioner not working is because the car needs coolant. The car AC repair technician will top it off or replace it completely. The coolant is exposed to extreme engine and road heat, dirt, road debris, quick stopping, and vibrations. The coolant will evaporate eventually.
• Compressor: The car AC repair technician will check for clogs and  leaks with the compressor. Clogged and leaking compressors can’t build up a pressure high enough to cool the refrigerant. 
• Cooling fan: This will be inspected the replaced if needed. After a lot of use, a cooling fan can burn out, the blades get chipped, a fuse blows, or a relay gets burned. If the fan was poorly installed, or has come loose, a car AC repair technician will repair if possible or suggest a replacement. 
• Electrical:  An electrical problem can be caused by faulty signals being sent that don’t let the air conditioner cool. This can be a bad module, bad sensors, or a  broken wire.

Why did my car AC stop blowing air?

If there isn’t any air coming through your car’s ventilation system, it doesn’t mean the air conditioning is broken. It may be the fan. The majority of cars on the road today have one multi-speed fan and it blows air through several ducts and vents that are selected by the driver. 

These different speeds are determined using the climate control system that consists of a small computer module. The fan switch sends signals to the computer module that tells the blower module when to activate the fan. A car AC repair technician will often determine that the fan is burned out and quit working or only works on one speed (usually the lowest or the highest). 

 An air conditioning technician may also find that the resistors themselves are burned out. This is an easy and fast car AC repair. Most cars that is two screws and disconnect the electrical connection. 

However, not all cars are the exact same, which is why taking your car in for professional car AC repair service is recommended.  Car AC repair technician has been trained with car ac repair how to make the repairs and has the proper car ac repair tools to do the job correctly, as well as recharge the system with freon. 

What does it mean when your car AC blows hot air?

If your car air condition is blowing warm air, it could be one of the following issues: 

• REFRIGERANT LEAK: Most car AC repair needs are because the refrigerant (freon) has leaked. A trained air conditioning technician will check for leaks and if they can be repaired or if the unit needs to be repaired. 
• FAULTY CONDENSER: The air conditioning system in a car pulls heat and humidity out of the car and is absorbed by the refrigerant. The condenser keeps the refrigerant cool and the cycle continues. If the condenser isn’t working, the entire car air condition process stops working. 
• BROKEN COMPRESSOR: A car’s air conditioner main component is the compressor. It is what circulates the refrigerant so if the refrigerant isn’t circulating, the air conditioner isn’t working. 
• ELECTRICAL SYSTEM: What if all the air conditioning components are working but hot air is still blowing out the vents? Most likely, the car AC repair technician will find a blown fuse or frayed wire.
