How To Check The Freon In A Home Air Conditioner? What Causes It?

How to check the freon in a home air conditioner

It is the air conditioner that does a goddess chore on a hot warmer day, keeping the households refreshed. What if it shows malfunctioning all at once? How to check the freon in a home air conditioner is a puzzle you come to pass when you see the fellow is not working in its typical way.

The accurate level of freon is a crucial feature to get the maximum efficiency of an air conditioner. You can keep these levels up to date if you have done the compulsory inspections on time with the help of an HVAC technician. To start our project on checking the freon level, let’s find out the features of the refrigerant in a nutshell.

What is Freon?

Freon is gas with CFC molecules where one or more hydrogen atoms are replaced by chlorine and fluorine, sometimes by both halogens. This non-combustible gas contributes to the cooling process in AC machines by absorbing heat inside the house and releasing it out of the house.

How To Check Freon In A Home Air Conditioner?

If you experience a warm atmosphere inside your home while the machine is on, then it is something that must be confirmed before going to any further extent. We hear by must state strictly that the freon levels are a fact that must be checked and refilled necessarily by a professional in the subject.

Why You Should Not Check Freon On Your Own?

If vapor or liquid freon is contacted with the skin or eyes, a high possibility of severe irritations occurs. If by any chance exposed to high levels of freon, pulse rate and respiration increase and sometimes may result in cardiac arrhythmia, creating a high risk of heart or brain failure.

A person may be subjected to CNS depression which slows down the central nervous system. The issue has the capability of making an individual even end up in a coma.

What Are The Signs of Low Freon Levels In Air Conditioners?

Now you have verified that doing self-investigations by opening up the unknown system of the machine after reading a manual or an article is a thing that you risk your own life together with your beloved family members. Rather than focusing on how to check the freon in a home air conditioner, it is the wisest thing to be aware of identifying a freon leakage.

Ways of pre-detecting such a hazardous situation will save your health, time, and money too. If you suspect that the machine does not work correctly, check whether it fulfils the following criteria or not.

Increment in electricity bill

When the refrigerants are low, the machine continuously works as it cannot maintain the required cool condition inside the house. It is pretty usual to have a sum more than that of colder months in summer. If you have got an unusual bill in your hands unless you didn’t introduce new appliances to your home, it is the right time to look closely at your AC machine.

Vents that blow warm air

Take your hand and feel the air that comes out from the vent. Do you feel warm? If the result is a warm air touch, make sure to follow some other steps to confirm that the freon has leaked.

More time to cool the atmosphere

You are very familiar with the total time it takes to make cooler air inside. But if you do not feel the same, although it is a long period passed the usual time, then the suspect regarding a leakage ascends.

Ice on the refrigerant line

The surrounding moisture will turn into solid form and form as the ice around the refrigerant line when in leakage of freon.

Ice on Evaporator coils

If there is less freon, the temperature inside the evaporator coils also decreases parallelly, and the moisture around becomes frozen. 

Releasing hissing sound

When freon leaks from valves and refrigerant lines, a hissing sound will be emitted. All you have to do is to do a closer hearing. If the sound is more potent, it is evidence that your unit has a leakage more of a primary stage.

Clogging in the air filter

The released cold air is filtered via the air filter to avoid the entrance of dust and various pollutants inside the house. A clogged air filter blocks the freon line acts as a barrel to the airflow and makes the machine work speedily.

How to Confirm A Freon Leakage In an Air Conditioner?

Before calling for an agent, you can try these simple tricks and methods on your unit for further confirmation if you have any doubts.

  • Refrigerant leak detector

It is evident that all this equipment does not provide reliable answers all the time. IR detectors measure the refrigerant amount when placed near a suspected area and give a reading here.

  • Soap bubbles method

Apply a paste of water and soap in the place or places suspected of leaking freon. It will form bubbles if such an emission takes place. But sadly, this method only found large-scale leaks. 

  • Visible oil leakage

Use a piece of cloth and wipe a place like an evaporator coil or accumulator. If there are oil patches, a refrigerant leakage could have taken place. Because often oil comes out together with freon.                                                       

  • Blower fan observation

Switch the thermostat to on and then observe the outside unit of your machine. The normal state is rotating. But if you find a still fan, that means there is an electrical issue or an issue with the fan or connected appliances. But the chance of being a freon leakage never goes null as your find a not working fan. 

Final thoughts

During the lifetime of an air conditioner, there is a probability of meeting a freon leakage at least once. Emissions that happen in small amounts do not cause any health issues. But if not treated in the first stages, the leakage will worsen and create a dangerous environment for the whole household. It is a harm to the health of the machine too.

Therefore, whenever the symptoms appear, don’t delay the treatments!
