Fur Coats
In the trades, we call a dirty outdoor unit a “Fur Coat.” It may look fuzzy, but it’s suffocating your heat pump. During the pandemic, I got hooked on rug-cleaning videos—the same thrill I get when stripping away years of dirt from a clogged system. So I implore you—nay, beg you—don’t wait until the first frost to find out your heat pump is struggling under a fur coat.
