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
