One of the most common questions that HVAC contractors get about refrigerant is, “how often does it need to be refilled?”
The answer might surprise you, though—it’s “hopefully, never!”
No, AC refrigerant shouldn’t need to be refilled on a regular basis. This is actually a common myth among homeowners, that refrigerant is something that depletes over time, sort of like gasoline does from a car or an oil-powered appliance in your home. This just isn’t the case with refrigerant, however, which continuously cycles through your cooling system or heat pump, transferring heat rather than generating it like other types of heating systems do.
