View Full Version : Army Trained Certified HVAC Tech seeking position in Kansas City Metro
11-17-2006, 05:41 PM
I've just moved back to the Kansas City Metro and am seeking a full-time position in the area.
I am an EPA Universal certified HVAC tech and hold an Army MOS (Military Occupational Specialty) of 52C - Utilities Equipment Repairer, a position I still serve in as a soldier in the MO Army National Guard.
If you are looking for a hard working team member, or know someone who is, please let me know.

Superheat: Any increase in the temperature of a vaporized liquid above its boiling point.
Subcooling: The process describing decrease in temperature of a liquid below its saturation temperature.
More importantly, though, do I know how to measure this in the field so I can practically troubleshoot a system? Yes.
To determine the amount of superheat in a system, you take the difference between the Suction Saturation Temp (from your manifold gauge) and the Suction Line Temp (taken close to the serve valve in the condensing section).
To determine subcooling, you take the difference between the high side pressure (converted to temp) and the temperature of the liquid line (just behind the metering device near the evaporator).
high superheat & low subcooling = undercharged
low superheat & high subcooling = overcharged
very high superheat & high subcooling = blockage
low superheat & low subcooling = “mechanical” problem ( probably w/ the orifice)

high superheat & high sub cooling. Don't forget underfeeding txv, starving evaporator and backing up liquid in the condenser.
seems to me that he has a great understanding.
You should hire him.

and I will hire you! Frank

did you get my e-mail?
11-18-2006, 04:11 PM
Frank - yes I did get your email, I sent a reply last night. Let me know if you didn't get it and I will resend. You might check your junk mail folder, your email ended up there on my yahoo account.
And as far as your list of definitions - now you're just waving the red flag. I can't walk away from a challenge. I will get you your answers later tonight when I've more time to write. Right now I'm off to the children's edutainment center in Lees Summit with my kids where I can act like a 2 year old for a few hours.
And thanks for the replies you guys.

It's probably a good thing - I was going to have to guess on a couple.

52C is that still Ft. Belvoir? If so been there done that.

controldude - Most (if not all) of the initial MOS training for 52C is now done at the Ordnance Mechanical Maintenance School located at Aberdeen Proving Grounds, MD.
However, there are several regional training institutes located around the nation you can attend for reclassification (i.e. changing your MOS) training in 52C. They are shorter than the APG school and you don't have to put up with as much BS as you do in initial AIT.
Slimkc This may sound like a crazy question but I have always wondered what the military is using now for training manuals ?????
I use to see tons of the old military manuels in the library that were for about ever military piece of equipment or vehical out there.
May I ask...... what kind of books are they using now ?????

dec - the actual MOS training manuals are pretty slim. They mostly just list skill sets and training points that need to be accomplished, and leave it to you to know how to do what's needed. However, for each skill and for each piece of equipment, a cross-reference is given to another technical or field manual.
I guess a good way to understand it is to know that there are three types of manuals we use 1. Training Manuals (that provide a training outline and skills needed) 2. Technical Manuals (that give the nitty-gritty details on equipment and tasks, and 3. Field Manuals, which as a 52C we don't much use.
Each of the pieces of standard equipment has it's own tech manual, which is useful because much of the Army HVAC equipment is manufactured by names not much seen on the civilian side - names like Red Dot, Zhendre, Dantherm, etc.
However, you'd be surprised at the number of times you'll find a soldier pulling out a regular "civilian" manufacturers technical manual because a lot of what you see in the sand box, and even back home, (especially at the establised bases) is off-the-shelf equipment from the big name manufacturers. Most of what you see, and work on, in the army would be all in a days work for your average technician.
