An air conditioner can quietly punish bad habits. A dirty filter, a thermostat that gets constant temperature whiplash, or an outdoor unit buried in yard debris can force the system to work harder while the electric meter keeps spinning. Worse, some habits that seem harmless can add unnecessary wear to expensive components.
Most of these problems do not require a dramatic home makeover or a wallet full of cash to fix. A few simple changes can help your AC move air more efficiently, maintain a comfortable temperature more easily, and avoid some of the strain that can shorten its useful life.
