re: Mini splits and dust

Heating and cooling with a (Mitsubishi) mini-split. My shop is kind of a sty. I have an air filter that takes a lot of dust that gets past the DC out of the air. I still need to blow the dust out of the mini-split a couple times a year on top of cleaning the plastic screen filter it has, but I haven’t had any problems with the mini-split after almost three years of use, knock wood.
