Always thought those refrigerant leak detectors were overkill until I found a pinhole in a coil in Wichita last week
My buddy kept pushing me to buy a heated diode leak detector for like $150 and I figured my old bubble spray was fine. Then I spent 3 hours chasing a slow leak on a walk-in freezer at a diner near the highway. The soap would show tiny bubbles but I couldn't pin it down. Finally borrowed his detector and it found a pinhole near the bottom of the evaporator coil in about 2 minutes. That tool saved me from ripping the whole unit apart for nothing. Has anyone else had a cheap tool actually fail you bad enough to spend real money on the good version?

Did you ever factor in how humidity makes the bubbles thicker and actually hides smaller leaks? I found that out the hard way when my spray kept giving false negatives on a humid day and I almost condemned a good coil.

Spent 3 hours with soap bubbles just to find out your eyes ain't a leak detector.
