Your air conditioning runs on electricity, but the key source of how an AC actually does its job is the chemical refrigerant that circulates through it. We want to mention this upfront because people often make the mistake of thinking refrigerant is an energy source for an AC that can potentially run out after enough use. Refrigerant isn’t the power source of the AC: it’s a heat transference medium, which is a fancy way of saying that it’s what allows an air conditioner to move heat from the indoor air (cooling it down) to the outside.
Unfortunately, an AC’s copper refrigerant lines can develop leaks, and when that happens an air conditioner will be in all sorts of trouble, both short- and long-term. In this post we’re going to look at leaking refrigerant and why it’s a problem you’ll want fixed as soon as you notice it.
