You might be surprised to learn exactly how your auto air conditioning system works. While it’s commonly assumed that the AC generates cool air, that’s not quite the case. Actually, it blows hot air, with all the heat removed through a peculiarly complex, multi-step process. In a nutshell, your auto air conditioning works by condensing the refrigerant (Freon), which in turn raises its temperature. This passes through a dryer, where contaminants and moisture are removed, then into an accumulator where it’s slowed down further, leading to a loss of both pressure and temperature. The evaporator then cools down that air further still before the ventilation system pushes it out—and you experience it as a blast of chilly air!
Your air conditioning unit keeps the car comfortable, but that’s not all. It also helps keep it contaminant-free, the air reasonably clean and healthy. Finally, your auto air conditioning unit can help to demystify foggy windows in the winter months, which is a major safety feature.
If you ever find that your auto air conditioning isn’t working as it’s supposed to—that is, that your auto air conditioning no longer provides nice, cool air—that’s the #1 sign that it’s time for an AC check. With that said, there’s merit to getting AC service done as regular, preventative maintenance—perhaps when you have your tires rotated or your oil changed. This allows you to stay on top of your AC help, and address any potential issues before they spiral out of control.
Responsible car owners get their oil changed about twice a year. They get their tires rotated, as well. They might do this work themselves; more likely, they go to a service station like Meineke in Winchester MA. As you show diligence to these routine auto maintenance steps, don’t forget about your auto air conditioning. Your auto air conditioning works harder than you might think: It takes hot air and cools it, cleans out contaminants, and removes extra moisture. Through a multi-step process, it moves cool air from your refrigerant (Freon) to the vents, where you finally get to experience cool, refreshing air in your cabin. That’s a lot of hustle, so it’s no wonder your auto air conditioning needs some TLC from time to time.
A lot of drivers have the auto air conditioning system all wrong. They assume it’s pretty straightforward, creating and then disseminating cool air. Actually, it’s quite a bit more complicated than that. In a multi-step process that begins at the compressor and ends at your air vents, the auto air conditioning actually creates warm air, then strips out all the moisture and contaminants—cooling and depressurizing it all the while. Obviously, this requires a lot of work, so it stands to reason that the auto air conditioning system might need to be inspected and repaired from time to time.
The surest way of knowing that your auto air conditioning needs an inspection is that it’s not working the way it’s supposed to—plain and simple. Specifically, an AC that’s no longer pushing out cool air needs to be checked ASAP. Head down to Meineke in Winchester MA to have it done!
