Hey everyone, came across this site looking for some Lon info. I have worked in the hvac industry for 15 years. I am currently doing a lot of Daikin startups and troubleshooting. I have also been doing startup and service for the Mcquay rep. Our company works on about everything, refrigeration, pumps, chillers, controls etc. I am finding it hard to keep up with everything we work on. Maybe this site can help.
