Steps to Check Aircon Refrigerant Level

If your central air conditioner suddenly stopped cooling your home as it used to, the freon might be the culprit. You may be wondering if and how you can conduct your own investigation into this matter.

If you are not a trained professional and you suspect that your central air conditioner is low on freon, you should have a trained professional evaluate it. You can acquire leak sniffers, gauges, temperature probes, and other gadgets, but you probably won’t be able to correctly diagnose the problem and fix the refrigerant. It would be dangerous for you and your family to try. Below are the steps to check refrigerant level.

When Does a Home Air Conditioner Need Freon?

You shouldn’t need to add any more freon to your air conditioner if it’s functioning properly. On the other hand, leaks are almost inevitable over the course of an air conditioner’s lifetime. A recharge will be required because of these leaks.

It is possible for air conditioning refrigerant to leak in a number of different ways, including through the refrigerant line itself, damaged or broken valves, and other cracks or openings. If you suspect your air conditioner’s refrigerant level is low, you should first conduct some troubleshooting to eliminate other possible causes.

In addition to extending the life of your air conditioner, calling in the will help you avoid making an expensive error. are known for their AC servicing and can inspect the freon level in a central air conditioning system. 

Checking the Amount of Refrigerant:

Subcooling requires a temperature difference of around 5 Kelvin while superheating necessitates a difference of around 10 Kelvin. Too little overheating and undercooling will occur if the coolant levels are too low. You’ll need a digital thermometer, some paper, a pen, and a refrigerant slider to figure out the difference between superheating and subcooling.

1. Figure Out What Kind of Coolant You’re Working With:

Information like this can be found on a type plate in your setup. Information like the number of plates and type of gas as well as the number of circuits and the potential for global warming are included.

2. Take a Look at the Gauges:

High and low pressure, as well as discharge and suction pressure, can be seen on the pressure gauges of nearly every AC unit. You can confirm the discharge and suction pressure in the manual if your system doesn’t include a built-in gauge.

3. Find the Temperature of Evaporation or Condensation:

The evaporation and condensation temperatures of refrigerants change with pressure. One way to set this is with a refrigerant slider. Place the slider to the dew point to find out the evaporation temperature. Condensation temperature can be detected by adjusting the slide to the “bubble” setting.

4. To Check the Temperature of the Setup, Use a Digital Thermometer:

Take the suction pipe’s temperature when it’s superheated. You can check the subcooling by taking a temperature reading just before the expansion valve.

5. Determine the Amount of Superheating and Subcooling That will Occur:

You can figure out the superheating and subcooling now that you have all the information you need. Subtract the temperature of the suction pipe from the evaporation temperature to obtain the superheating. Subcooling is calculated by taking the condensation temperature and subtracting it from the discharge pipe temperature.

The system is functioning at the proper refrigerant level if temperatures are between 10,000 and 5,000 Kelvin. Get it checked out by a pro if not.

May I Do My Own Freon Recharge?

If the freon level in your air conditioner is low after you’ve performed the tests, you should get it recharged. Low refrigerant levels can cause serious problems for your air conditioner and make your home unbearable to live in. The compressor could be damaged beyond repair if the refrigerant leaks back to the outside unit.

The cost of a new compressor could exceed the cost of a new air conditioning system. Prevent this from ever happening by making sure the Freon is always at a healthy level. It’s tempting to imagine that topping off the Freon in your air conditioner is a simple operation and an excellent way to save money. However, you should never attempt to recharge Freon on your own due to the inherent dangers involved.

The professional expertise required to successfully complete a Freon recharge is beyond the scope of what a typical homeowner can provide. As a result, it’s crucial to bring in an expert. If you want your air conditioner to perform at its best, hiring a technician to charge it and do other maintenance checks is a good idea.

You can easily identify and fix any issues with the system by performing a thorough examination.
