What is an AC evaporator?

Well, let’s start with the basics. Like, the super basics. AC stands for air conditioning.

Okay, with that out of the way, let’s get to the evaporator, which is a really big part of your air conditioning system. How important is the AC evaporator? Well it’s the part of the air conditioning system that’s responsible for, you know, making the air cold. Or at least one of them. That seems like it might be an important thing, yeah?

So, how does it work? Well, I won’t bother you with all the ins and outs, because, frankly, I don’t think you really care that much. But we’ll cover the basics. Liquid refrigerant is metered into the evaporator by an expansion valve or orifice tube. Inside the evaporator, the refrigerant is transformed into a gas (hence the name evaporator). At the same time, the blower motor is pushing warm air across the evaporator. And because the evaporator is a heat exchanger, it absorbs the heat, keeping you cool.

And that’s how you keep from leaving sweat marks all over your nice car seats.
Evaporators are extremely durable, and you usually won’t ever have to replace yours. But if there’s moisture in the air conditioning system, it can cause corrosion. That can ultimately damage, and ruin the AC evaporator.

Symptoms of a failing AC Evaporator

Air conditioner isn’t working

Pretty obvious, I know. If your AC evaporator is busted, your air conditioning system doesn’t really have a way of producing cold air. Unless it’s a frigid day, and you turn on your fans, you simply won’t have a way of getting cold air into your cabin. The temperature of the air depends on how broken the AC evaporator is. If it’s just starting to go, you might still get some cold air, it will just be like a brisk spring day amount of cold, rather than dead of winter cold. If the AC evaporator is fully busted, then say goodbye to any level of cold air.
