There are a few things that could cause an air conditioning line set to become empty and kinked. One possibility is that the line set was not installed properly, and it became kinked during installation. Another possibility is that the line set has been damaged by rodents or other animals.
If you have an empty and kinked air conditioning line set, you will need to repair it as soon as possible. This is because an empty line set can allow air and moisture into the system, which can damage the compressor.
Here are the steps involved in repairing an empty and kinked air conditioning line set:
1. Turn off the power to your air conditioner.
2. Disconnect the electrical wires from the air conditioner.
3. Remove the insulation from the line set.
4. Straighten out the kinked section of the line set.
5. Apply a sealant to the kinked section of the line set.
6. Wrap the line set with insulation.
7. Reconnect the electrical wires to the air conditioner.
8. Turn on the power to your air conditioner.
If you are not comfortable performing this repair yourself, you should contact a qualified HVAC technician to help you.
