Where do AC refrigerant leaks occur?
A refrigerant leak typically appears in the evaporator coil. The refrigerant is mostly a superheated gas while in the evaporator coil and can therefore leak from smaller holes. Refrigerant is part gas and part liquid, depending on where the chemical is in the process and in the system.
What to do if you have a leak in your refrigerant system?
The leak may be preventing the system from producing cool air. Weak or warm air does not always indicate a leak because this problem may also stem from air loss in your ductwork or a dirty filter clogged with dirt and dust. Check your filter and replace it, if necessary. Then, have your contractor inspect the ductwork for holes or tears.
Can a refrigerant unit be replaced with sealant?
While sealant can be effective for small leaks, this is usually a temporary fix and will not help long-term. Sealers can also create openings and blocked passages in the system, so this is not the ideal course of action. Should you replace your unit? The age of your system needs to first be considered.
What causes a copper refrigerant line to leak?
Corrosion. If the copper refrigerant line is exposed to contaminants, it can lead to corrosion and subsequent leaks. This could occur through direct contact with ductwork or other dissimilar metals, or it could result from exposure to a corrosive atmosphere from chemical storage or furniture refinishing Settlement.
Why is my refrigerant unit leaking warm air?
The leak may be preventing the system from producing cool air. Weak or warm air does not always indicate a leak because this problem may also stem from air loss in your ductwork or a dirty filter clogged with dirt and dust.
What to do if your AC is leaking refrigerant?
Again, if you’re not familiar or experienced with AC repairs, we highly suggest contacting an AC repair company to check for refrigerant leaks. When a refrigerant leak is present in your AC system, sometimes oil will also leak out. This substance is pretty simple to detect given its thick, dark consistency.
When to call in a professional for a coolant leak?
If the leak is caused by the condenser, evaporator coils, or by the compressor, calling in a professional repair person would be necessary because these are generally sealed. It can be a costly repair and you will need to get a few estimates before settling on your service person.

What are the signs of a refrigerant leak?
Frozen evaporator coil: Ice crystals are a tell-tale sign of a refrigerant leak. It’s important to check your evaporator coil (the indoor coil) periodically for new formations. When the refrigerant level circulating through the evaporator coils is insufficient, the coils will not adequately absorb heat.
