Leaking Refrigerant Lines Leaks Refrigerant Lines Refrigerant Line for Air Conditioning

Text in the illustration

the refrigerant itself
at connections - especially at condenser due to movement of the condensing unit
where lines pass through walls
note:
the refrigerant itself boil off as soon as it leaks out - look instead for oil residue as a sign of leakage
mechanical damage - lawn mowers, foot traffic, etc.

Generated explanation

The illustration shows refrigerant lines running from a house wall to an outdoor air-conditioning condensing unit. Callouts identify vulnerable leakage locations at the wall penetration and at connections, particularly where movement of the condensing unit can affect the lines. The exposed run near ground level is identified as susceptible to mechanical damage from lawn mowers and foot traffic. A note explains that refrigerant boils off when it escapes and that oil residue should be sought as evidence of leakage.
