How to Check Refrigerant Level in AC

Here are 5 simple steps to check the refrigerant level and determine if it is low.

  1. Identify the type of refrigerant your unit uses by checking the type of plate.
  2. Use pressure gauges to check the refrigerant pressure. If it's low, it indicates a low level of refrigerant.
  3. Use a refrigerant slider to determine the evaporation and condensation temperature, and make sure to record the temperature readings.
  4. Use a digital thermometer and refrigerant slider to calculate the temperature difference between subcooling and subheating.
  5. Calculate the refrigerant level by subtracting the evaporation temperature from the suction pipe temperature for superheating and subtracting the discharge pipe temperature from the condensation for subcooling.

If your refrigerant levels are not within the normal range, which is 10K to 5K, you likely have low refrigerant levels, and you should call a HVAC technician to confirm the levels and refill the coolant if necessary.

How to Tell If Ac Refrigerant Is Low

  1. If you notice that your air conditioning unit is not cooling your home as effectively as it used to, this can be a sign of low refrigerant levels.
  2. If there is ice forming on the evaporator coils or refrigerant lines, this can be another sign of low refrigerant levels.
  3. Hear a hissing or bubbling sound coming from your AC unit? This can indicate a refrigerant leak, which can lead to low refrigerant levels.
  4. There may be a sudden increase in your electricity bill, it may be because your AC unit is working harder to cool your home due to low refrigerant levels.
  5. If you smell a sweet or musty odor coming from your AC unit, this can be a sign of a refrigerant leak.

When your AC needs Freon, the system is likely low on refrigerant. Freon is a type of air conditioner fluid that has been widely used for decades to keep homes and businesses cool. Without enough Freon, your AC will not be able to function properly, leading to reduced cooling capacity and higher energy bills.

In order to fix this issue, you may need to have a Freon charge performed by a technician. During this process, they will add more refrigerant to your AC system to ensure that it's operating at its optimal level.

So don’t hesitate to reach out for the best HVAC technicians there are available! They will surely help you understand how to check the Freon in a home air conditioner and even do the job for you! Call them now!
