Think about it. Your window unit pulls in hot, sticky air, runs it through a filter, and blows out cold, crisp air. That filter is like the unit’s nose hairs, catching dust, pollen, and even pet fur.
When it gets clogged, the AC has to work twice as hard. It’s like trying to breathe through a straw while jogging. Not fun, right?
A clean unit also saves you money on electricity. It’s a win-win: you get cooler air, and your wallet stays a little fatter.
