An AC service may be just to fix to keep your car cool. The summer season is upon us and for most of us a working air conditioner is a must for our vehicle. Some air conditioning repairs are simple, while others can be more extensive. More than likely, if you have a newer car and the AC is not blowing as cold as usual, an AC Service, which includes AC fluorescent dye to detect and confirm an accurate diagnosis, will do the trick. With older vehicles an AC service is always recommended as the first step. There are many components to a vehicle’s AC system and an array of possibilities that could affect its performance. Below are a few of the basic AC components:
- Compressor: This compresses and circulates the refrigerant in the system
- Refrigerant: A substance called R-134a. The refrigerant carries the heat.
- Condenser: This changes the phase of the refrigerant from gas to liquid and expels heat removed from the car.
- Expansion valve or Orifice Tube: This works as a nozzle and functions to simultaneously drop the pressure of the refrigerant liquid, meter its flow, and atomize it.
- Evaporator: This transfers heat to the refrigerant from the air blown across it, cooling your car. (Pictured is an evaporator recently replaced in a 1999 Toyota Land Cruiser. It was time.)
- Receiver/dryer: This functions as a filter for the refrigerant/oil, removing moisture and other contaminants.
AC Service = Trust the Pros
Though we do not recommend repairing your own vehicle’s AC, Fix-Your-Car’s-Air-Conditioner is a great resource if you are making a decision on a repair because it explains a vehicle’s air conditioning system, the parts involved, and how they work.
