Check out what can happen if your compressor fails: It doesn’t take many metal flakes to destroy a fresh component, and flushing an entire AC system is again not a task non-professionals are equipped to handle. If not, then those chips can find their way inside the new compressor. Internal failure of the compressor can spread small metal chips through the vehicle’s system, which must be completely cleaned out prior to replacing that component. This type of diagnosis is typically beyond the skill set of even experienced do-it-yourself repair types.Ĭompressor problems are another hard issue to identify, yet a common air conditioning issue.
A tiny leak in the evaporator, for example, can be almost impossible to spot without using specialized dyes injected into the system that then show up as colorful spots where the leak is located. Hunting down something as simple as a refrigerant leak isn’t easy, either. If it’s unsealed, the refrigerant must be captured and stored, and not allowed to vent into the atmosphere, adding an extra layer of complexity to the entire operation. This means that all automotive AC repairs have to be accomplished within the context of keeping the system sealed at all times. Moisture and other contaminants can easily corrode and damage a car’s air conditioning system from the inside out, sometimes invisibly so, to the point where it is no longer repairable. Not only can a leak create a loss of refrigerant, which will impact performance, but it can lead to moisture being introduced into the system. Each and every component, hose, and hardline needs to be protected from exposure to the atmosphere. This is where automotive AC repairs start to reveal the intricacies that can make it so difficult.įor starters, the entire air conditioning system must remain sealed at all times. In practice, maintaining the process that’s described above requires the teamwork of a precise set of components, each of which has to be working at 100 percent in order to effectively and efficiently keep you cool.
The sequence is then repeated, gradually drawing the warmth and humidity out of your vehicle’s cabin and replacing it with cool air through the vents. The gas is then passed through a compressor that pressurizes the chemical, adding further heat, and then finally through a condenser, which returns the chemical back to a liquid state, radiating heat away from it as part of the process. The BasicsĪir conditioning works on a fairly simple principle: by using an evaporator to pull ambient temperature air across a set of coils filled with a refrigerant, that chemically changes from a liquid into a gas as it absorbs heat. What makes AC repair such a challenge? Let’s take a quick look at some of the problems posed by automotive air conditioning. In fact, air conditioning systems can be among the most complex of projects waiting for you in your car or truck, which is why even experienced DIYers often turn to expert help rather than tackle the job themselves. Automotive AC repairs often require more than just buying a can of refrigerant and refilling an empty system.
