If you know how to detect the signs of refrigerant leaks you will be able to restore it quickly and spend less in reparation costs.
Weak and warm air blowing through the vents
The most common sign is near the vents. You will notice a weak and warm air flow coming through the vents. The air often has a damp smell. However, weak and warm air may not always indicate a leak because at times there may be air loss in the ductwork or it may result from a dirty air filter, which you will need to replace.
A hissing sound
If there are cracks and holes in the condensator line, refrigerant will leak through these openings. There will be a hissing sound when the refrigerant moves out of the lines. The hissing may be heard near your outdoor unit but it will be most detectable inside your house where the indoor unit is located.
Refrigerant leaks can be repaired by various methods. However, the process is not easy and can even be dangerous for untrained people. Refrigerant leaks are not only harmful to the environment and other HVAC related components, but can be a real health hazard. Do not try any repair by yourself if you are unsure or do not have the required tools! Call a professional to help you diagnose and repair these leaks.
