This is a common question people have regarding their air conditioning systems. The simple answer is no. But we need to explain the answer because the question comes from a major misunderstanding about how air conditioning systems operate. Amateurs and shady contractors can use this misunderstanding to sell people on services they don’t need and which can damage their air conditioning systems.
We have plenty more to say about why adding refrigerant to an air conditioner is only done as a repair, not as a routine service.
