I was a helper for most leads there. I mainly worked on outdoor units such as heat pumps and regular a/c. Everything we did was brazing, so i worked with nitrogen, refrigerant. I've also ran new linesets and slim duct for new units. I was an installer while i was at bowman ans didn't do any service.
Commercial work at remco. while there I did a lot of soldering and pro press fittings. worked with copper, pvc, cpvc, and black iron pipe. I also ran water lines, installation on pipe, gas lines, set shower pans, installed tiolets, and installed sinks.
