Everything You Need to Know About Freon

How much is refrigerant, or Freon? Well, it’s a complicated question. One of the first things worth considering is what exactly “Freon” is.

“Freon,” technically speaking, is a brand name for various types of refrigerants for air conditioning units. However, in the same way we call any sort of bandage a “Band-Aid,” we started referring to any refrigerant as “Freon.” There are two main varieties of refrigerant you should know about:

  1. R22 Refrigerant (Obsolete)
  2. R410A Refrigerant

Which Refrigerant Do I Choose?

You may ask, “So my unit needs Freon, but what type?” That depends on your model of air conditioner, but generally speaking, older models will use R22, while newer models will use R410A. That’s because the production and importing of R22 is no longer legal in the United States.

Due to the harmful nature of R22 to the planet’s ozone layer — with consequences such as intensified global warming and climate change — R22 has vastly fallen out of common use in favor of R410A. Continuing to use your R22-dependent air conditioning unit is legal. However, you must consider the following: would you like to use refrigerant that is better for the environment? And are you prepared to pay more for R22, which can only be obtained via recycling, meaning it will only become more and more expensive over time?

When determining where to buy Freon for home AC units, figure out the long-term savings of switching to R410A. A new air conditioner installation may be in order for you, if so.

How Much is Refrigerant?

Okay, it’s time to talk money. How much does it cost to put Freon in a central air unit? Now that we’ve distinguished the two major types of Freon, let’s talk about prices.

How Much Per Pound of Freon?

  • R22 Freon: $90-$150/lb.
  • R410A Freon: $50-$80/lb.

How Much For a Full Refill?

  • R22 Freon: $180-$600/refill
  • R410A Freon: $100-$300/refill

As you can see, the average price of R22 is higher than R410A.
