Aircon Gas Top Service Singapore - How to Fix Refrigerant Issues

Air conditioners depend on the refrigerants they use to cool down their surroundings. A refrigerant takes in outside heat and releases cool air after it travels through the compressor and evaporator. 

Refrigerant issues are also a type of problem that air conditioners can run into. In this article, we’ll take you through the common refrigerant issues and how to fix them. 

How Refrigerant Works

Let’s recap. An air conditioner’s refrigerant helps to cool plenty of appliances, including your air conditioner, refrigerator and freezer. The refrigerant travels through the inner copper coils in the evaporator and condenser to take in heat and release it into the outside environment. 

It shifts from a low-pressure gas to a high-pressure liquid that then moves along with a fan’s help. This liquid continues to compress before it’s quickly removed using a special nozzle and converted into a gaseous state again. 

How to Determine the Refrigerant Your Air Conditioner Uses 

Newer air conditioners typically use either the R-410A or R-32 refrigerants that are considered more environmentally friendly. If your air conditioner was manufactured before the year 2010, it probably uses the R-22 refrigerant. For example, modern air conditioners like the Mitsubishi R32 aircon uses the R-32 refrigerant. It’s easy to find a Mitsubishi R32 refrigerant using an air conditioner model in today’s market. 

You can also take a look at the label pasted on the side of your air conditioner’s outdoor unit. It’s usually written there, or in the user manual. If all else fails, you can simply contact the supplier you got it from and ask. 

Common Refrigerant Problems 

Frozen Coils 

Inside your ductless indoor unit is a network of copper coils. These coils are cooled by the refrigerant as it flows through. Although they are icy to the touch, it should not reach the point where they freeze over. 

If you notice frosty coils, it’s likely that the refrigerant is leaking. 

Warm Air Released 

When your air conditioner fails to fulfil its main purpose of releasing cool air, it means that you need to take a look at your refrigerant. When it lacks refrigerant, it cannot provide cooling. Although it may be due to other issues, the most probable one is because of insufficient refrigerant. 

How to Fix Refrigerant Issues

Top Up Gas 

If your refrigerant levels are low, simply recharge your refrigerant. Remember to only engage a professional air conditioner contractor to do this because of the high levels of pressure and because refrigerants can be toxic. 

Your air conditioner contractor will top up the gas swiftly and safely without doing any damage to the system. 

Check for Leaks 

Sometimes, the problem doesn’t lie with insufficient gas. It can be because of a leak that’s allowing the refrigerant to escape. Enlist the help of an air conditioner expert to help you conduct a thorough check and seal up the leaks that they find. If the refrigerant level is too low, proceed to top it up as well.
