I leave my minisplit in heat mode at the lowest setting (62F) all winter. Avoiding any condensation on cold metal is nice, also not worrying about having anything freeze, and being able to walk out to the shop and just start working is great. I don’t turn the split up while I’m out there, just leave it at 62. The shop gets up to about 75F on nice sunny days in the winter because my shop windows catch the winter sun, and the split will only kick in a couple times overnight.

The unheated, adjacent wood and motorcycle storage area stays above the freezing temp of Pepsi all winter that way, too. 

My sweetie says it costs us about $40 or $50/ month for the coldest month or two. I think the shop heating season here is four months total, maybe five.

May you have the day you deserve!
