Air Conditioning Services

A properly working AC keeps you comfortable while you drive. A number of issues can be the source of an auto AC failing to provide the cold air you rely upon. Our highly trained technicians are skilled in A/C diagnosis, evacuation, and auto AC repair in Lewisville, TX.

The loss of refrigerant is a common cause of air conditioning failure. The leak will require repair, and the system recharging. Furthermore, in some situations, if air has entered the system, evacuation will be required. Evacuation removes the air and moisture, stopping the potential for additional damage to the system. This is why DIY recharging is not advisable, as few persons have the knowledge or the specialized equipment to provide evacuation. Trust your auto AC repair in Lewisville, TX to Fifth Gear’s certified automotive technicians.

How the Auto AC Works

The simple version of how your vehicle’s AC works involves changes in temperature related to pressure. Turning the AC on activates the compressor which compresses the refrigerant causing the temperature to be raised. As it flows through the condenser located in front of the radiator, it loses heat. From the condenser, it passes through the dryer where moisture and contaminants are removed, and afterward, it flows through the expansion valve (accumulator) where the refrigerant slows, reducing its pressure and the temperature before arriving at the evaporator. In the evaporator, the temperature of the refrigerant is lowered, and moisture is removed. The blower motor blows air over the cold evaporator and delivers cold, dehumidified air through the vents and into the vehicle’s interior.

Recharging the System

Refrigerant does not wear out, it leaks out. When this occurs, you will notice the AC is not producing air as cold as it was. As the refrigerant becomes lower in a slow leak, the temperature becomes less cold. Of course, it is also possible for a malfunction that results in the sudden loss of refrigerant, and its ability to cool at all. Common causes of refrigerant leaks are faulty service valves, a worn refrigerant hose, and a worn or faulty compressor.

In 1996 the U.S. began transitioning from ozone destructive R-12 to R-134-a, a refrigerant that is not as destructive as R-12. In 2013 the U.S. began to transition from 134-a to a safer refrigerant called HFO-1234yf on select vehicles. Experts state HFO-1234yf has almost no environmental impact.
