@hvacknowitall: Commercial is king... The amount of experience and knowledge you'll attain working in commercial HVAC is incredible. I was invited onto a job site by Armstrong to document this pump change over to the Design Envelope pump and Pump Manager. The riser was frozen using liquid nitrogen, this way we did not have to disrupt building operation to replace the triple duty valve. Pump Manager can track pump performance remotely and update the building on any issues before a major repair is needed. #hvac #hydronicpipefreezing #hydronics #hvacservice #hvacservice
