How To Fix Low Refrigerant In Your AC Unit

If your AC unit is producing low levels of refrigerant, there are a few things you can do to fix the issue. Low refrigerant can result in an unbearable musty smell, decreased air conditioning efficiency, and even damage to your AC unit. In this article, we’ll outline the steps you need to take to diagnose and fix low refrigerant in your AC unit.

What is Refrigerant?

Refrigerant is a fluid used to keep air conditioners and other appliances cold. Low refrigerant levels can cause your AC unit not to work as well or at all. Here are some tips on how to check and fix low refrigerant in your AC unit:

  • Check the temperature gauge. If the AC unit is not cooling properly, the temperature gauge may be inaccurate. This can indicate a low refrigerant level.
  • Check for leaks. If the AC unit is not cooling properly, there may be small leaks that are letting air out of the system. Check for signs of water damage and repair any leaks if necessary.
  • Test the system for leaks with a leak detector . A leak detector can help find small leaks that may be causing problems with the AC unit.
  • Change the compressor filter . The compressor filter helps to keep contaminants out of the refrigerant system and maintains consistent cooling performance over time. Replace it when it becomes dirty or damaged.

When to Check the Refrigerant Level

In most cases, checking the refrigerant level in an air conditioner is a simple process. You will need to open the ducts that bring air into and out of the unit and look for white or yellow liquid. If you see any of these signs of low refrigerant, your unit needs to be serviced or replaced.

If you don’t see any liquid, but the unit seems to be not cooling as well as it used to, it might be time to check the refrigerant level. To do this, you will need to turn off the power at the main breaker and remove the cover on the AC unit. This will allow you access to all of the ducts and components inside. If you see any white or yellow liquid, then your unit needs service or a new compressor.
