Refrigerant is the substance responsible for cooling the air coming out of your air vents. When properly pressurized in a closed-loop system, the refrigerant evaporates into a gas that will be used later to cool an interior space. But when there is a leak in this closed system, the refrigerant levels can drop, preventing operation. In other words, the fan will only blow.

If your air conditioning unit does not work at all, the problem may be electric. Fuses, relays, pressure switches and other electrical components may fail at any time due to age or defect. When this happens, the system is designed to shut down for security. Only an experienced mechanic has the knowledge and tools to isolate the problem of diagnostic tests.
Another common problem in-car air conditioning repair in older vehicles is the used compressor. At the heart of the unit, the compressor is responsible for refrigerant flow throughout the system. When it breaks down, the air vents will only blow. Although age is primarily responsible for compressor failures, the critical component may also fail due to contamination or other defective parts.
