Learn different types of HVAC components used in residential and commercial buildings. These are the top selling digital products made by me and sold on aircondlounge. R513A refrigerant has a GWP of 573 and an ODP of zero which is much better than R134a refrigerant and even R32 refrigerant.
With the phasing out of older air conditioner refrigerants, such as R-22 (or Freon®) many homeowners are wondering if their cooling system is ready for the future without Freon. To check whether you need to update your heating and cooling system or not, go to the outdoor unit of your air conditioner and check if it has R22 written on it or not. If you find out that your AC is using the banned R-22, you must think about AC replacement as soon as possible.

In contrast, Puron does not deplete the ozone layer, making it environmentally friendly. Previously, air conditioning systems used hydrochlorofluorocarbons . The EPA phased out these refrigerants because it causes ozone depletion. Indeed, all AC refrigerant types play a common role in absorbing surrounding heat and generating cool air once it passes through the evaporator and compressor. However, there is more than one type of AC refrigerant, which confuses users on which to use on their cars.
Many different refrigerants are available now, but only a handful are approved for use in residential air conditioners. ACs built before 2010 use a refrigerant called R-22(also known as Freon®). Freon is a powerful greenhouse gas that is known to damage the earth's ozone layer.
Why Must Homeowners Check AC Refrigerant Level?
If you’re looking for something with thermodynamic properties similar to Freon, R-407C is a popular choice. Because it’s safe and affordable, many manufacturers are creating equipment compatible with the refrigerant. Unusual noise from your AC unit – Air conditioning units produce a soft humming sound.
That’s why many R410A refrigerant gas tanks are upside down when charging into an air conditioner. Technicians are pumping in liquid refrigerant instead of gas refrigerant. The suction pressure of R410A air conditioners is usually around 125 psi which is much higher than R22 air conditioners. Although the production of R22 air conditioners is limited, there are still plenty of R22 air conditioners in operation around the world now. Besides, for any Air Duct Cleaning, AC installation, AC replacement and AC repair services, call Green Leaf Air to ensure you get the best quotes and satisfying service. As soon as you find out that your AC is leaking refrigerant, you must call an HVAC professional and fix it ASAP.
REFRIGERANT
If you have a top-rated air conditioning system, you should know what type of Freon is used in a home air conditioner. Whether you have a window AC or a central air unit, the type of refrigerant you use heavily affects the AC cooling power. R-410A contains no chlorine, so it’s not damaging to the atmosphere’s ozone layer.
Refrigerants come in liquid form, but after passing through evaporator and compressor, it turns to gaseous form. Refrigerants perform a vital role in everything that cools, such as refrigerators, freezers, and both home and car ACs. To appreciate why this matters, you must understand how the ozone layer works.
Who Regulates Heating, Ventilation and Air Conditioning Refrigerant?
Apart from R-410A, you will also find appliances that use R-290, which is an HC refrigerant. In case, you have the option of choosing HC as a refrigerant, go for it as it is the most environment-friendly refrigerant. However, HC is still not used actively because it is highly flammable.
R-22 refrigerant, also known as Freon, is a common refrigerant in central air conditioners. Like some alternative refrigerants, R-22 is linked to environmental effects, such as ozone layer depletion. Finding the correct replacement refrigerant is nearly impossible without knowing what kind of air conditioning unit you have.
After the HC group, the safest refrigerants belong to the HFC category. From our previous discussion, we know that CFC has been phased out and HC is not commonly used because it is highly flammable. The refrigerants in this category are R23, R134A, R404A, R407C, R10A, R417A, R422A, R422B, R422D, R507, and R508B. The damage caused by HCFCs is very minute in comparison to CFCs.
So, if your unit was made before 2010, it probably uses Freon. You may not know this, but for virtually every person in modern society, refrigerant touches your life nearly every day. As of now, R32 refrigerant is the latest refrigerant that is still implementing in many residential air conditioners. The transformation from R410A refrigerant to R32 refrigerant is still ongoing.
