The A/C system in your vehicle improves the efficiency of the process of moving heat. It uses three methods of removing heat from your car: Radiation, Conduction and Convection.
The heat in your vehicle is blown across the evaporator coils using convection.
The heat is absorbed into the cool refrigerant (Freon, R-12, R-134a, etc.) inside the coils using conduction.
The refrigerant moves the heat into the condenser using convection.
The heat is absorbed into the condenser fins using conduction.
The heat then transfers back into the atmosphere using radiation.
The A/C system also handles other functions, including removing heat from the interior of the vehicle, and providing movement of air in the interior of the vehicle.
Our A/C Service Includes:
- Check pressure to test operation, refrigerant charge and outlet temperatures
- If the system is found to be low on refrigerant, a leak test is performed to find the source of the leak
- Refrigerant may be added to top off the system (includes DYE)
- Check for evidence of refrigerant cross-contamination. The refrigerant R-12, trade named DuPont Freon, has been replaced by R-134a. This refrigerant is tossed as being environmentally safer than R-12 and has been a standard since 1994. The refrigerants are not inter-changeable. The refrigerant R-134a cannot simply be added to an older vehicle that was using R-12, without first flushing the system and replacing old components and the oil in the compressor. On older cars, this retrofit conversion may be a cost-effective option
- Check compressor's drive belt and tension
