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!
Contrary to popular belief, your auto air conditioning doesn’t simply create cool air. Actually, the process is quite a bit more complicated and multifaceted than that. It begins when the compressor condenses your vehicle’s refrigerant—raising its temperature and sending it to the condenser, where it begins to lose heat. Passing through a dryer, the air is stripped of pollutants and airborne contaminants. In the accumulator, it’s cooled further still, and also depressurized. It eventually makes its way to the ventilation system, where it’s cooled down completely, and is released into your cabin as nice, refreshing air.
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.
As for when it’s necessary to get your AC looked at, the short answer is: Any time you find that you’re not getting cool air like you used to. Additionally, it’s typically smart to have an AC check once or twice a year, as part of your preventative maintenance. This helps you keep ahead of any potential problems, resolving them before they turn into bigger or more expensive repair needs.
The best way to stay on top of potential problems is just to make air conditioning service calls regular. Work them into your standing service appointments at Meineke in Vernon Rockville CT. Having an AC check once or twice a year will almost always be sufficient.
It’s important to get a regular AC check because your auto air conditioning does more than you might imagine. Sure, it keeps your ride cool and comfy—but that’s just the beginning. It also helps you keep your windows from getting fogged up during winter. And, it decontaminates your air, keeping your cabin clean and clear. All of that’s pretty pivotal to you enjoying your vehicle, which underscores the importance of regular air conditioning inspections and maintenance work.
