2001 yr built Train with multiple refrigerant leakage in both R-22 circuits. Unit has operated in cooling practically nonstop from day one. Manufacturing business with a huge heat load inside machine shop, gas heat is not hooked up, no need. Shop has a total of 32.5 tons of a/c keeping it cool. I have to say, this is a very well constructed RTU.
