How Often Does AC Need Freon? Here’s What You Should Know

How often should Freon be replaced in air conditioner? In an ideal world, you would only ever need a Freon for your AC if you have a leak. Read our article to learn more.

If you’ve been searching for an answer to the question, “how often does AC need Freon?” look no further. In a nutshell, you are not required to recharge your air conditioner on a predetermined schedule. 

So, if that’s the case, how often do air conditioners need Freon? Most systems need Freon replacement anywhere from once every two to five years from a professional HVAC Contractor. The most significant exception to this rule is when there is a leak in the air conditioning system, which decreases the amount of refrigerant in an AC unit over time.

What Is a Refrigerant? What Is It Used for? 

So, what is refrigerant for AC units? Refrigerant is a compound or chemical substance, typically found in a gaseous or fluid state, used in a heat cycle to move heat from one location to another. You’ll find refrigerant in home ACs, freezers, refrigerators, and the ACs of various vehicles. 

What Coolant Is Used in AC?

When it comes to HVAC coolant, R-22, more commonly known as Freon, is the most prevalent kind. However, because of growing environmental concerns in the United States, the use of Freon is being phased out. As a result, fewer supplies are available, driving up the price. R410A, also known as Puron, is the refrigerant most likely to be used in newer systems since it is environmentally friendly.

3 Common Symptoms of Low Freon in Central Air Conditioner 

It might have been a while since you last got your AC serviced, so how do you know if your air conditioner needs Freon? It is now the middle of summer, and you’re most likely dependent on your central air conditioning equipment to keep yourself and those around you cool, so it’s better to fix any potential issues in advance.

Below, we’ve compiled a list of symptoms of low Freon in central air conditioners, followed by some of the factors that play into it.

  • The Device Does Not Cool Like It Did Before: Low refrigerant may cause the unit to provide inefficient cooling.
  • The Compressor Runs More Often: A leak in the system might cause the compressor to run more often, which leads to increased electricity costs. 
  • Ice or Frost: Frost or ice buildup on the evaporator coils might indicate low Freon in AC.

Other Problems with the Cooling System of the Air Conditioner   

When the temperature outside is almost intolerable in the summers, most individuals depend on their HVAC coolant to keep their commercial and residential spaces cool throughout the season. However, these systems might occasionally get plagued by issues that prohibit them from operating as expected. Here are some other problems to look for. 

  • Drainage System: Problems with drainage may lead to excessive humidity levels.
  • Dirty Filter: A clogged filter can restrict airflow and cause the system to have to work harder.
  • Faulty Thermostat: A faulty thermostat can stop the air conditioning unit from reaching its intended temperature.           

What to Do If Your Air Conditioner is Leaking

Now that we know that one of the main reasons that may leave you wondering, “How often does AC unit need Freon?” is a refrigerant leak, there are a few things you can do to resolve the issue with expert help:

  • Turn off the power connected to the air conditioner at the breaker box.
  • Get in touch with a trained AC repair specialist as soon as possible.
  • Examine the outside of your machine for any traces of damage or leaks.
  • Check the inside of your house for any signs of obvious water damage.
  • Start your AC equipment and listen for any strange sounds or odors.
  • Keep a careful check on your monthly energy bills and look for unexpected hikes.

How Often Does AC Need Freon?

As discussed at the beginning of this article, you are not required to recharge your air conditioner on a predetermined schedule. But how often does a home AC need to be recharged? Well, Most systems can get by with Freon replacement every two or five years. 

However, the most significant exception to this rule is when there is a leak in the air conditioning system, which decreases the amount of the refrigerant in the AC unit over time. To conclude, you shouldn’t have to add Freon unless you’re repairing or replacing AC coolant.

With this information, you now know the answer to the question, “How often do you need to add freon to a central air conditioning unit?”
