 So at your evaporator coil, uh, inside your apartment or your home, uh, in AC mode, there's actually something very cool and scientific going on there. Um, pretend this is, um, a frozen pipe, right? I'm gonna put my hand hands on this pipe. What happens here is the cold in the pipe sucks the heat out of my hands, right?

So essentially the same thing is happening here, that is happening at your evaporator coil. You have your copper or aluminum coil, uh, that has refrigerant in it. That is ice cold. It's very cold as the. Air or the heat that is in your home or apartment get sucked through that evaporator coil. That metal pipe absorbs the heat in the air and it causes that refrigerant to start to boil.

Uh, the refrigerant then moves to the compressor and it converts it from a low temperature, low pressure gas to a high temperature, high pressure gas. And then it goes outside, uh, to, well, your compressor is outside of your condenser, but that's when it then runs through the coils outside. But why that's important is you need to make sure that you have.

It's proper airflow, clean coils, proper, um, um, a clean filter, the right size filter, um, on your evaporator coils. Because without this process, without a, a, a proper airflow or a properly charged, uh, AC system. You're not gonna be pulling the proper humidity out of the air or enough of the humidity outta the air.

Sometimes you may connect your gauges to a, a condensing system, and you may see that your system's perfectly charged. But the resident complains that the AC runs all the time. They're clammy, uh, because it's not adequately removing the humidity out of the air. So. Think about that illustration. Alright, uh, when you are working on your air conditioners and hopefully, uh, you can provide, uh, your residents, uh, a more comfortable home.
