I thought power sanders were for amateurs until a tight deadline proved me wrong

I avoided them for years because of the dust cloud. Now I see they cut sanding time in half and give a smoother finish.

I finally organized my fermentation station with a homemade wooden rack... so much easier to find everything.

Why do so many techs say you must flush every coil after a burn out?

I've fixed several units without flushing and they ran fine for years. What's the real risk if you just replace the filter drier?
