Eric, could you explain the term Medium temperature repair?

[globalcompressors]

Basically we're talking about anything above freezing, 32', and below
48' or so. High temperature refrigeration is usually above 50' but below
68' or 70' cooling only, like produce, candy, pastries, and so on. Medium temperature is like you refrigerator at home keeping drinks, dairy products,
leftovers, in the range of 38' to 42'. Low temperature refrigeration is anything below freezing and usually between 0 and -20F. In some cases I have repaired 2 stage, low temp, equipment reaching down into the -50 range, not needed here though.

 Air conditioning repair is considered easier for two reasons, we're not as cold on the evaporator coil temperature and we're dealing with lbs. of refrigerant vs. ounces. There is a lot less room for error in refrigeration especially when were talking colder temperatures. Air conditioning uses R22 where as refrigeration can use r12, 134a, 502, 404, 416, mp39, etc.

  All I'm saying, is the people you use, need to be proficient in refrigeration and familiar with what refrigerant will be the best choice for you and your equipment. How many times have we all heard about someone taking their unit to be repaired and then the compressor locks up, or the coil springs a leak or something else altogether? And if you see someone using a "clamp on" piercing valve, grab your unit and RUN!!!  

  Quiz people. Ask questions about what kind of work they do. How long have they been doing it, etc.. I am more than happy to assist MY customers. I do however, have little patience with someone who is supposed to be knowedgeable, in their profession, refrigeration, and can't read a set of guages, use a scale, or solder a piece of copper tubing to make a repair. This frustrates me  '> to no end. I guess I'm having a flash back to my days as a compressor remanufacturer and having to hold these guys hands, explaining an expansion valve, cap tube systems, proper air flow, to wiring a compressor. These GUYS should know!!!!! '>        Sorry '> ... I'm just tired of seeing folks taken advantage of, that's all.     Probably more info than was asked for, sorry for that.   Sometimes I can get a bit wordy.

Hope this helps,
