My name is Mike Moynihan from HVAC Technical Academy. I’m going to show you, Mrs. Smith, what we refer to in the industry as a pump down. Basically, a pump down is taking all the refrigerant from your inside unit anywhere in the lines. We’re going to suck it all the way back to your outdoor unit. We’re going to trap that refrigerant inside here. That’s going to allow us to make any repairs on your copper lines, on your filter dryer, your evaporator coil, your thermal expansion valve.

Anywhere that holds refrigerant will now not have refrigerant. It’ll be trapped inside here. So, the red hose is my liquid line. The blue hose is basically my suction line. So, what I’m going to do to your unit, Mrs. Smith, I’m going to close my high side. And then I’m going to very quickly close my suction line, the blue hose. I’m going to close that, which is going to suck all that refrigerant back to this unit very quickly. That process is cheaper than doing a recovery, which would cost you a lot of

money. And this is much quicker. Thank you, Mrs. Smith.
