Leak Detection

The most common cause of low refrigerant or freon is tiny leaks in copper couplings or weld joints.

Other causes include:

  • Nails in copper lines from construction
  • Nails from recently hung pictures
  • Bad seal at compressor terminals
  • Loose connection or seal at metering device
  • Bad or loose schrader valves

We use top of the line electronic refrigerant leak detectors to sniff out all possible areas of refrigerant loss and can detect leaks as small as 0.10 oz./year.

In some cases it may be necessary to inject Ultraviolet dye into the system and use a special UV light to trace down the leak. In other cases we may simply be able to spot refrigerant oil near the leak.
