One thing that helps out is to use synthetic compressor oil in it after you break it in. It doesn't get as thick in the cold and gives the motor less resistance for this reason. The amsoil PCK I have in mine has a pour point of around -50* F and will start up in my compressor at 17* F no problem. The Mobile Rarus 427 that originally came in it has a pour point of 45* F which means at 17* F it would be like set up jello making the compressor unusable in the winter as it is in an unheated (except when I am in there working) shop. I've never seen the castair but have the 5hp single stage Eaton, the motor on this compared to the HD compressors is like comparing a big block to a 4 cyl. I like mine & it's a good feeling not to have to look at how much air a tool uses, with these if you hook it up it will run, mine will pump up & shut off while running a 6" DA sander. I too would vote for the Eaton, probably because I have one & like it so much
