Refrigerant leaks in older copper line sets
Why it happens here
Homes built in the 1990s and early 2000s in Zephyr Ridge North often have copper line sets that develop pinhole leaks from vibration and age. The leak is slow, so cooling degrades over months instead of failing all at once.
Our approach
We use an electronic leak detector and pressure testing to find the exact spot. Then we repair or replace the line set, pull a deep vacuum, and recharge with R-410A or R-32 to factory spec. We also add a filter drier if one is missing.
