Auto air conditioning service
Auto air conditioning is a method that alters the temperature and pressure of air. This process takes place in an auto air conditioner. An auto air conditioner is a machine that has five major parts and these are the compressor, the condenser, the evaporator, the expansion valve and the drier or accumulator. These major parts work together with pipes and use refrigerant to transport heat to and fro delivering cool air to your vehicle. The refrigerant which is also known as Freon can alter its state on absorbing heat to change from liquid to gas and when the hot gas is exposed to cool temperature it turns from gas back to liquid and therefore the refrigerant is used in a process similar to the refrigeration cycle. In the compressor the liquid refrigerant is compressed and as it absorbs heat becomes a hot gas. This gas gets to the condenser where it is cooled and it changes back to liquid. In the evaporator air is blown across the cool refrigerant and as it absorbs heat from the air it reverts back to a gaseous state. In the drier or accumulator moisture and other contaminants are removes from the refrigerant before it gets to the compressor using a desiccant and filters respectively. The expansion valve is responsible for controlling how cool you would like your air. All these functions occur in a single unit severally to keep you cool. The refrigerant used in the newer models of cars is the R-134a which is environmentally friendly and has been approved for use globally. In case you have an older car model the technician can retrofit your car with the latest version of refrigerant from the previous R-12.
Auto air conditioning repair pricing varies depending on who you get to do your repairs and how they charge you. However, you may notice a decrease in the number of calls you make to a repair service company if you arrange for regular servicing for your vehicle’s AC. The AC performance check should be done by a qualified technician and it involves cleaning the parts and checking that all the parts are working as they should. The first thing the technician will do is to perform a performance test on your auto air conditioner. This often includes a visual check of all the parts of the AC, a performance test where he will check for how efficient the system is and he will also do a pressure test to check if all the levels are normal using a PSI and will be able to detect any areas with the pressure being too low or too high. Any problem with the pressure could be as a result of a blocked valve or a hole or even air in the system. Then he will check for leakages in the system using a special trace dye. This is because refrigerant is highly evaporative and on contact with air it quickly evaporates and this is why it is so difficult to detect any leakages on your AC on your own.
