Which gases are used in AC? R290 and R32 are both gases used in air conditioning units. They're also known as refrigerants, which means they help cool down your room by turning into liquids when pumped through the system. Compared to other gases such as R12, and R22, they are safer and environment-friendly to use.
Generally speaking, R-32 is more cost effective and can lower monthly energy bills. R-32 has a higher pressure ratio than R-410A. Basically, a higher pressure ratio means the refrigerant can cool more with less refrigerant, which also means less electricity is required for the system to cool your home.
R-32 is the most balanced refrigerant in terms of environmental impact, energy efficiency, safety, and cost-effectiveness. Refrigerant is a medium for conveying heat.
R-410A is not only better for the ozone layer; it also provides a better overall operation. It absorbs and releases the heat better than R-22, making your compressor run cooler so that it does not overheat.
The Key Differences Between R22 & R32
R22 loses on both fronts. This gas has a medium ozone depletion potential, which is too high to be approved for any use. Meanwhile, its global warming potential is 1810. R32 has a zero ozone depletion potential and a GWP of 675.
Changes to the Dangerous Goods Legislation, effective in 2021, has new categories for A2L refrigerants. R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change. R32 is a flammable refrigerant.
Air conditioner refrigerant gas legislation
R32 is the newest and most popular air conditioner refrigerant gas. This is because of its relatively high efficiency and low GWP (Global Warming Potential). R410A is also popular, but its higher GWP means that its more harmful to the environment.
The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur.
In 2010, the U.S. stopped the sale of newly manufactured residential air conditioning units and heat pumps that use R-22 because of its particularly harmful impact on the ozone layer when released into the air. On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22.
Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22. The benefits of Freon MO99 include: Capacity — The ability of Freon MO99 to heat or cool a given space is closer to Freon R-22 than any other refrigerant on the market.
R22 (also known as HCFC-22) is a chlorofluorocarbon (CFC) once widely used as a refrigerant. If your home or office AC is over 10 years old, it's probably using R22 freon. However, R22 Freon is banned in the U.S. today.
It's not flammable and it doesn't create carbon monoxide or other contaminants in the air as it cycles through your air conditioner. However, just because it's inherently safe doesn't mean it can't become dangerous. Any refrigerant, be it R-22 or R-410A, can be dangerous if inhaled or consumed by human beings.
R-410 A. This special refrigerant is created from a blend of hydrofluorocarbon refrigerants, difluoromethane, and pentafluoroethane. Additionally, it is non-ozone depleting, which is a tremendous credit to its current and future use as a household refrigerant.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
R-410A PHASE-DOWN TIMELINE
We will reach a 70% decrease by 2029. In 2034, we will see 80% less R-410A being produced than it is today, and the phase-down will end in 2036 with another 5% reduction.
Choose non-flammable refrigerants: R134a. R410A. R407C.
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.
R-22 is an HCFC refrigerant that is often used in air-conditioning equipment. To protect the Earth's protective ozone layer, the United States is phasing out R-22, along with other chemicals.
The Phaseout of R22 Refrigerant
By January 1, 2030, the government will ban all production and import of HCFCs, including R-22.
When you replace an air conditioner or heat pump and upgrade from R-22 to R-410A, the ideal solution is to replace your refrigerant lines. This is because the mineral oil used in R-22 systems is not compatible with the new R-410A refrigerant and oil.
How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.
To retrofit an R-22 system with R-410A system your line set must not be more than 25-50 feet in total distance. If the line set is longer than this, you will have to replace the line set with larger lines.
Which gases are used in AC? R290 and R32 are both gases used in air conditioning units. They're also known as refrigerants, which means they help cool down your room by turning into liquids when pumped through the system.

What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant R-454B due to its excellent performance for ducted systems and zero ozone depletion potential. For mini-splits, we selected R-32, designed to optimize efficiency and reliability in ductless systems.
The lower GWP of R32 means it has a lower impact on the environment compared to R22 and R410A. Energy efficiency: R32 has a higher energy efficiency compared to R22 and R410A, which means that air conditioning systems using R32 require less energy to operate and can result in lower electricity consumption and cost.
