Refrigerators are indispensable for extending the shelf life of our perishable food supplies. However, over time, problems can arise that compromise the effectiveness of these appliances’ cooling capabilities.

A refrigerant leak is a common issue that requires Freon (or refrigerant) to be added in order to restore the refrigerator’s cooling ability.

So, how much does it cost to put freon in a refrigerator? Moreover, can you take the DIY route and do it yourself? Let’s find out in this article!


How Much Does It Cost to Put Freon in a Refrigerator?

Freon, or refrigerant, is a chemical compound that transfers heat and aids in the cooling process in refrigeration systems. It’s vital for keeping the cold temperatures inside a fridge, which is necessary for keeping perishables fresh.

In most cases, you can expect to pay between $150 and $200 just for the service call when you need Freon put into a refrigerator. This cost accounts for the technician’s efforts in identifying the problem and recharging the system’s refrigerant. The price of the Freon itself, which can vary greatly, is not factored into this estimate.

To provide a more accurate estimate, consider the following scenarios:

Scenario 1: Small Refrigerator with a Minor Leak

A service call may cost as little as $150 if your compact refrigerator has a small refrigerant leak. A small leak in Freon could set you back between $50 and $100. That would put the grand total somewhere between $200 and $250.

Scenario 2: Large Refrigerator with a Significant Leak

The price of a service call could be closer to the upper end of the range, around $200, if the refrigerator is larger and has a significant refrigerant leak. It could cost anywhere from $150 to $200 to replace the Freon in such a system. As a result, the overall price tag may be somewhere between $350 and $400.

Scenario 3: Additional Factors

It is important to remember that the final price may be affected by other variables. For instance, additional labor costs may be incurred if the refrigerant leak is hard to find or fix.

Some refrigerants are more expensive than others due to environmental regulations and availability, so the type of Freon used can also impact the overall cost.


Factors Influencing the Cost of Adding Freon to a Refrigerator

Here are the factors that influence the cost of adding Freon to a Refrigerator:

Dimensions and Model of the Fridge

The price of refilling a refrigerator’s Freon tank is highly dependent on the model and capacity of the fridge. Costs associated with recharging the refrigerant levels of larger refrigerators may be higher than those of smaller ones.

The cost of a fridge can vary widely depending on its make and model. Side-by-side and French door refrigerators, for instance, may have more intricate cooling systems that necessitate expert maintenance, which could raise the price of the service.

Situation and Supplier

The price of refilling a refrigerator’s Freon tank depends heavily on where in the world you live. Due to factors like cost of living and level of competition in a given market, the cost of services like refrigerant replenishment can vary widely from region to region. Service fees tend to be higher in urban areas and other places where the cost of living is higher.

Price of Freon

The price of the Freon itself is a major factor in the total price, even after accounting for labor costs. The size of the refrigerator and the severity of the refrigerant leak determines the amount of Freon needed. Freon refills can vary in size, with smaller leaks requiring less gas than larger ones.

The cost of Freon may vary from one type of refrigerant to another. It’s important to talk to your service provider about the type and amount of Freon you’ll need, as well as to request a detailed breakdown of the costs involved.


How Do You Know If Your Refrigerator Is Low On Freon?

In this part, we’ll talk about how to tell if your fridge is running low on Freon and what to do about it.

Tracking the Efficiency of Cooling Systems

A decrease in the refrigerator’s ability to cool is the first and most obvious sign that it may be low on Freon. Your perishables will remain at just the right temperature thanks to the refrigerant’s ability to draw heat out of the refrigerator and freezer as it makes its way through the system.

Inadequate Freon levels make it difficult for the appliance to keep the desired temperature.

Ineffective cooling can be indicated by the following:

  • More rapidly than usual food spoilage.
  • The softening or melting of ice cream or other frozen treats.
  • Can’t keep drinks cold like they used to.

Any of these problems are signs that your refrigerator needs to be serviced.

Strange Noises

Low Freon levels in a refrigerator are also indicated by strange noises coming from the unit. Freon is a gas that circulates through the cooling system’s coils and tubes.

A unique noise can be produced by cooling coil cavitation when the refrigerant pressure is too low. The noise is often compared to a pencil being tapped on the coils.

These tapping or hissing sounds could indicate a problem with the Freon and require immediate attention.

Condensation Around the Freezer Motor

Another sign of low Freon levels is the presence of moisture near the refrigerator compressor. The compressor is essential because it moves the refrigerant around the system. Low levels of Freon in the system increase the likelihood of leaks, and condensation is a common byproduct of these leaks.

Inspect the area around the refrigerator’s compressor and the floor for any signs of water or condensation. This dampness is unmistakable evidence of a potential refrigerant leak that needs immediate attention.

Expert Opinion from an HVAC Technician

If you’ve noticed any of the aforementioned symptoms and you think your refrigerator might be running low on Freon, it’s time to call in the experts. The best course of action is to call an HVAC expert who has worked on refrigerators before. These experts have the training and tools necessary to make a correct diagnosis.


Can You Put Freon In A Refrigerator Yourself?

You should NOT put Freon in a refrigerator without the proper training and certification, as doing so could pose serious risks to your health and the environment.

Why Shouldn’t You Put Freon in Your Refrigerator Yourself?

This section will cover the reasons why you shouldn’t put Freon in a refrigerator on your own, as well as the risks involved, the importance of using certified professionals, and the rules and regulations in place to protect the environment.

Dangers to Health:

There are serious health risks involved in handling Freon without the appropriate training and safety gear. Freon is an odorless, colorless gas that can cause dizziness, shortness of breath, and even death if inhaled in high enough concentrations. Freon exposure can be fatal in the worst-case scenario. Freon is dangerous and must only be handled by those who have been properly trained.

Broken Home Appliances:

Damage to appliances can result from improper handling of Freon. Improperly adding refrigerant can lead to system malfunctions and expensive repairs or even a replacement if done repeatedly.

Legal Consequences:

Due to their potential environmental damage, refrigerants like Freon are subject to strict regulations from the Environmental Protection Agency (EPA). There may be legal repercussions for those who try to work with Freon without the proper certification and in violation of EPA regulations.


What Happens When You Put Too Much Freon In A Refrigerator?

Using too much Freon can cause a domino effect of problems that shorten the life and diminish the efficiency of your fridge. Here’s a detailed overview of what happens when you put too much freon in a refrigerator:

Compressor Oil Replacement

Problems arise when too much Freon is introduced into a fridge. At first, the surplus Freon makes its way into the evaporator coil, where it may combine with the oil used to lubricate the compressor.

The oil is displaced from its original location as a result of the interaction. This causes the internal pressure of the compressor to rise and eventually causes wear.

Over time, the compressor may stop working due to mechanical issues brought on by the increased pressure and friction within it. Because of this, the refrigerator may have trouble keeping food at the right temperature and may work much less efficiently.

Disturbing Squeals

A high-pitched noise is another obvious effect of having too much Freon in your fridge. This noise can be annoying and distracting, making it difficult to relax and enjoy one’s time in the kitchen. The stress on the compressor from the added Freon can also be reflected in the high-pitched noise.

Changes in Temperature

An excess of Freon leads to inaccurate temperature regulation. When an excessive amount of Freon is pumped through the evaporator coil, the temperature of the coil can drop to dangerously low levels.

As a result, the refrigerator’s temperature drops too low. There are a number of problems that can arise when the refrigerator’s internal temperature drops too low.

First, unexpectedly freezing temperatures can cause food to spoil and be wasted. In addition, ice can form on the evaporator coil if the temperature inside the fridge drops too low, preventing the air from circulating.

Because of this, the refrigerator may not be able to cool its contents as well as it otherwise could.

Faulty Mechanisms

Using too much Freon in your fridge can have serious long-term effects. Because of the added strain on the compressor and the potential for ice to form on the evaporator coil, mechanical failures may occur.

The refrigerator’s compressor, the most important part, could be damaged beyond repair if this happens.

More serious problems may necessitate a professional technician to replace the entire compressor unit, which is both expensive and time-consuming. This repair will not only put a dent in your bank account but also cause inconvenience because you won’t have a working refrigerator for a while.

Safety Precautions

If you want to keep your fridge running smoothly and avoid these problems, filling it with the recommended amount of Freon is essential.

Manufacturers of cooling appliances design their products to function at peak efficiency with a narrow range of refrigerant concentrations.

If you add too much Freon or otherwise deviate from these specifications, you may experience the aforementioned issues.

A professional appliance technician should be consulted if any of the aforementioned symptoms are present or if there is any suspicion that your refrigerator may contain too much Freon.

They are able to examine the system, identify the issue, and take corrective action, such as adjusting the Freon levels or replacing broken parts.


What Kind Of Freon Goes In A Refrigerator?

Following are a few types of Freon gases that are often used in refrigerators: 

Freon-12 (R-12):

Refrigerators used R-12, also known as FREON-12, as an early refrigerant.
However, this refrigerant was phased out due to environmental concerns after it was discovered that it had harmful effects on the ozone layer. Therefore, we no longer employ it.


In the 1950s, R-22 took over for R-12 as the preferred refrigerant.

Later research found that R-22, like R-12, contributed to ozone depletion, so it was phased out in accordance with international agreements.

Although its use has been gradually limited, R-22 can still be found in some older refrigerators. This means that R-22-using appliances are becoming increasingly hard to come by.


Most modern refrigerators use a refrigerant called R-134a. It was introduced in the 1980s as a more eco-friendly alternative to previous refrigerants and was developed by DuPont.

R-134a is now widely used in refrigeration systems because it has a much lower ozone depletion potential (ODP) than its predecessors.

Finding the Appropriate Coolant

It is crucial to correctly identify the type of refrigerant used in your refrigerator before making any repairs or servicing. Using the incorrect refrigerant can be dangerous and cause damage to the appliance.

  • It’s possible that the type of refrigerant used is described in the owner’s manual or other documentation that came with your refrigerator.
  • The refrigerator’s model number may also provide useful information. It is common practice for manufacturers to list the refrigerant in the model number or on a nameplate located inside the fridge.
  • If you are unable to locate this info or are still unsure, it is recommended that you seek the advice of a qualified technician. They are equipped with the knowledge and resources necessary to determine the correct refrigerant type.
