There’s a question many homeowners ask us that’s born from a common refrigerant myth—that question is, “how often does it need to be refilled?”
But the answer to this is actually, “hopefully, never!”
This is the myth. The refrigerant that flows through your heat pump system shouldn’t need to be refilled on a routine basis. This is because it’s not something that depletes over time like gasoline does from a car or oil does from an oil-powered appliance in your home. Refrigerant, alternatively, cycles through your heat pump continuously, transferring heat rather than generating it like other types of heating systems do.
So if you’re losing refrigerant, it means you have a leak.
