When your air conditioner stops cooling your home efficiently, you might suspect it’s run out of refrigerant. This chemical substance is responsible for cooling heat from warm air before it’s sent into your home.
But it turns out that most people’s idea of refrigerant isn’t actually true! The biggest myth about refrigerant is that it “runs out” from normal use.
Air conditioning systems are manufactured with enough refrigerant to last their entire lifespan. That can be up to 10 or 15 years!
So, if you suspect that refrigerant has vanished from your unit, chances are you’re dealing with something else instead: a leak.
