R-410A Questions & Answers

R-410a refrigerant is a popular heating and air conditioning refrigerant currently in widespread use. If you have questions about it, we have answers!

Do you need a license to buy R-410A refrigerant?

You do not need an EPA license to purchase R-410A. However, you do need a license to use it to charge a system. While we encourage responsible DIYers, there are some things you should definitely leave to a trained HVAC professional.

What is the difference between R-22 and R-410A?

The two refrigerants are similar in that they are both capable of cooling your home. However, they are not exactly the same. R-22 is less energy efficient and is ozone-depleting, the primary reason it is being phased out. Also, R-22 is much more expensive when it can even be found for purchase at all. Unless your old R-22 system is still going strong, there are very few reasons to stick with it.

Is R-410A a CFC?

No, it is not a chlorofluorocarbon. It is 100% non-ozone depleting. In fact, that's the whole point. R-410A is one of the alternative refrigerants developed in response to the 1987 Montreal Protocol. In the United States, the Montreal Protocol is enforced via Title VI of the Clean Air Act as implemented by the EPA.

Is R-410A a toxic chemical?

It's not instantly deadly, but R-410A is not a chemical you want to bathe in. In liquid form it is so cold that contact could cause frostbite. Avoid coming into contact with it. If you do get it on your skin, flush with water to remove the chemicals. Should symptoms persist or worsen, seek medical attention. And don't eat it.

Is R-410A reusable?

With the proper equipment and training, R-410A could be reclaimed for later reuse. Current regulations allow for reuse in the same equipment or in other equipment owned by the same person. Obviously, it is important to ensure any recovered refrigerant is not too contaminated for effective reuse. If it is, it should be properly disposed of by the certified reclaimer.

    It is, but it can be removed from a system, undergo a reclaiming process to restore it to its original state, and then reused.
