In this explanation, I'm going to talk about the crucial role refrigerant plays, highlight different types that are used, and discuss their effects on the environment. When we think about the future of cooling systems, what is included in a central air conditioning tune-up , it's important to recognize the comfort they provide us, but also to consider how they might affect our planet.
