One of the most common and threatening problems for an air conditioner is short-cycling. This issue is both the symptom of a problem and the cause of more problems. Although sometimes there’s a simple fix—like changing the air filter—in other cases it requires a much bigger repair, and contacting an HVAC professional right away is pivotal.
Unless short-cycling is stopped, it will eventually lead to premature AC replacement and waste a lot of energy until then.
