The most common cause of low refrigerant or freon is tiny leaks in copper couplings, bad coils, 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 the 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 detect leaks as small as 0.10 oz./year.
