Is R-410A going to be obsolete?
The act empowered the Environmental Protection Agency (EPA) to set HFC management and reduction guidelines. Following a directive by the EPA, new HVAC systems will no longer use R410a refrigerants as of January 1, 2023.
The leading replacement for R-410A refrigerant is a pure, single component refrigerant called R-32, which has one-third the global warming potential of R‑410A.
Beginning next year, new cooling systems will contain a refrigerant called R-454b with a lower global warming potential. This refrigerant is more environment-friendly than its predecessors but also mildly flammable. You can rest assured our ACS Air Conditioning Services technicians know how to handle it safely.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
The R-410A phasedown is on its way, are you ready for it? The HVACR industry is on the cusp of yet another refrigerant phasedown. R-410A is scheduled for elimination from all new systems in 2023.
HVAC industry alerts are now warning of significant price increases for 2023. There are four reasons for this increase: The cooling equipment components will perform higher to achieve a high-efficiency rating. This is a good thing as these components generally have higher quality and will last longer.
Two potential low-GWP R-410A replacements are R-32 and R-454B. R-32 is a pure, single-component refrigerant with zero ozone-depletion potential (ODP) and a GWP of 675.
If that's so, then what R22 there is in the system can never evaporate under the higher suction pressure of R410a. It will just flood back to reduce the compressor life and will greatly reduce the system capacity.
In most cases R32 is the superior refrigerant when compared to R410A. While neither refrigerant depletes the ozone layer, R32 has a lower GWP and is easier to recycle. R32 also has lower operating and maintenance costs and is nowadays more common than R410A due to the phase out.
SEER regulations
Beginning January 1, 2023, there will be two SEER-related changes. First, the minimum SEER rating will increase on HVAC equipment. Currently, new air conditioners must have a minimum SEER of 13 in northern states and 14 in southern states. In 2023, this will change to 14 and 15, respectively.
What refrigerant will Rheem use in 2023?
Air conditioning technicians and businesses should prepare now for a significant upcoming change in the HVAC industry: a new refrigerant. R-454b will be the refrigerant for the next 15 years, but even though its use will not be mandated until 2023, installers and HVAC technicians should be ready to use it starting Jan.
All Trane units manufactured since 2010 use R-410A.
Yet even they have reported phasing out R-32 in 2023 for an alternative with even lower GWP scores. Still other refrigerant alternatives that can meet the new environmental standards are under development such as R-466a by Honeywell, the first nonflammable, low-GWP option.
R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate. Ozone Depletion Potential of 0. Easier to recycle than R410A, as R32 is a single component refrigerant.
Where can I buy R32? R32 is available from most refrigerant wholesalers and stationary air conditioning component suppliers.
You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force.
This question seems to be better phrased as “can Puron/R410A make air colder than Freon R22?” Well, R410A performs much more efficiently than R22. As a result, it will cool a room slightly quicker – and use less energy to do it. But R410A can't make a room colder than R22.
Many HVAC manufacturers have already announced price increases going into 2023, making headlines as another round of price increases go into effect.
The best times to replace your HVAC system are the spring and early fall when the business is the slowest. During this time manufacturers offer specials to help sell more products and HVAC contractors are more aggressive with their pricing to help keep the dollars rolling and the crews busy.
New energy incentives make this a great time to install or upgrade a heat pump. The year 2023 may be the best for homeowners buying a new heat pump. The new Inflation Reduction Act (IRA) includes incentives for upgrading a home's energy efficiency, including tax rebates and discounted purchasing.
Is 16 SEER worth the extra money?
Benefits of a Higher SEER Rating
A rating above 16 SEER is associated with lower energy consumption, which translates to less money spent on energy costs. Replacing an 8 SEER AC or heat pump unit with a 16 SEER one may save you up to 50 percent on your energy bill.
To satisfy industry regulations, the HVAC industry is transitioning from Puron (R-410A) refrigerant to Puron Advance (R-454B) by the year 2023.
R410a is actually a blend of two different refrigerants, one of which is called R125. There's currently a world shortage of R125 because there aren't enough plants to produce it. Without enough R125, producers can't make enough R410a to keep up with the increasing demand.
R-22 is a refrigerant that is often used in air- conditioning equipment. Because R-22 depletes the ozone layer, production and import was further limited in 2010. In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available.
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.
The most commonly mixed refrigerants in the field are the replacements for R-22 — R-427A, R-438A, R-422D, and R-407C — which are often combined with the remaining R-22 in the system, said Maiorana.
Scientists discovered it was damaging to the environment and ozone, so manufacturing permanently halted on January 1, 2020. R410a is the replacement for R22.
Two other HFCs that are commonly used are --- R-32 for air conditioners and R-134A for refrigerators. R-32 is marginally better than R-410A as it has a lower potential to cause global warming. The global warming potential of HFCs will make governments eventually phase out these refrigerants.
R-32 is the most balanced refrigerant in terms of Environmental Impact/Energy Efficiency/Safety/Cost-Effectiveness for Stationary Air Conditioners and Heat Pumps.
Your HVAC System is More Than 10 Years Old
The average lifespan of an HVAC system is 15 to 20 years, but as these systems age, they tend to get less efficient. If your HVAC is over 10 years old, consider replacing it with a more energy-efficient unit, such as one that has earned the ENERGY STAR label.
Should I replace my 30 year old HVAC?
Check the age of your HVAC: If it's older than 20 years, it's likely time to replace. Check the safety of your HVAC: If it's leaking poisonous carbon monoxide, it's time to replace. Consider the repair costs: Are you paying more than 50 percent of the cost of a replacement during a repair?
Current ACs aren't going to cut it
Over the next few decades, the global demand for air conditioning is expected to skyrocket. According to the International Energy Agency, the number of AC units in buildings across the world should reach 5.6 billion by 2050, up from only around 2 billion units today.
Lennox cooling products now use chlorine-free R410A refrigerant, instead of the older R22 refrigerant (Freon). Because R410A contains no chlorine, it's ozone responsible. Plus, R410A allows higher efficiencies than R22, so it not only protects the earth's ozone layer, it also saves energy.
HFC-134a will no longer be approved for use in new light-duty vehicles manufactured or sold in the United States as of model year 2021 as a result of EPA's July 2015 final rule under SNAP (July 20, 2015, 80 FR 42870 ).
R-123 will be phased out for new HVAC equipment on Jan. 1, 2020; it will continue to be produced for servicing equipment until 2030. R-22 cannot currently be produced for use in new equipment; all production and import of new R-22 will end in 2020.
How Much Is R-410A Refrigerant per Pound? R-410A refrigerant costs approximately $3 to $8 per pound or about $75 to $175 per 25-pound container.
Daikin is the world's largest HVAC manufacturer. The company uses all-aluminum evaporator coils in its products, which create less breakdowns than other coils. Daikin also incorporates inverter technology which can maximize both efficiency and lifespan.
ECO-32 is a blend of high purity propane R290 and ethane R170. It is a reduced global-warming-potential (GWP) refrigerant. It is designed to replace R410a and R32 in most stationary residential and commercial air conditioning systems.
General Motors, Chrysler, and other manufacturers have chosen R-1234yf as the refrigerant to replace R-134a.
R-410A Refrigerant
Currently, the most common refrigerant used in new residential air conditioners is R-410A. It is one of the least damaging to the environment (and human health) and which could be used as alternatives to R-22. R-410A is a blend of different HFCs that don't deplete the ozone.
Does stronger ac waste more gas?
Using a vehicle's air-conditioning system increases its fuel consumption more than any other auxiliary feature. An air-conditioning (a/c) system can increase fuel consumption by up to 20% because of the extra load on the engine.
The most environmentally friendly refrigerants are hydrofluorocarbons (HFC) and hydrofluoro-olefins (HFO). HFCs are comprised of fluorinated hydrocarbons. While HFCs can contribute to global warming, they do not affect the ozone layer directly.
Beginning next year, new cooling systems will contain a refrigerant called R-454b with a lower global warming potential. This refrigerant is more environment-friendly than its predecessors but also mildly flammable. You can rest assured our ACS Air Conditioning Services technicians know how to handle it safely.
Propane (R-290), a valid refrigerant from all these points of view, is technically viable for small and medium-sized refrigeration and air-conditioning applications. However, concerns on flammability have slowed down its diffusion.

All new home AC units in North America uses R410a, also known as Puron. But this refrigerant will consequently be phased out. This is due to a continued focus on reducing compounds known to have an effect on the environment.
The kind of refrigerant used in residential air conditioner has changed a few times over the years, keeping up with technological advancements and environmental concerns. All modern home AC equipment in Tempe uses R410a, also referred to as Puron. But this refrigerant will subsequently be discontinued.
R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate. Ozone Depletion Potential of 0. Easier to recycle than R410A, as R32 is a single component refrigerant.
Improved efficiency: R410A is able to absorb and release heat better than R22, making it more energy efficient. Plus, because it's more fluid in temperature changing abilities, it does a better job heating or cooling your house quickly.
HFC-134a will no longer be approved for use in new light-duty vehicles manufactured or sold in the United States as of model year 2021 as a result of EPA's July 2015 final rule under SNAP (July 20, 2015, 80 FR 42870 ).
What is R-22 refrigerant being replaced with?
The most common R22 replacement is R410-A, a refrigerant that does exactly the same thing, but without the ozone-depleting qualities. R410-A is also sold and marketed as: GENTRON AZ-20, SUVA® 410A, and PURON® — all of which are EPA-approved for your HVAC system.
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.
If that's so, then what R22 there is in the system can never evaporate under the higher suction pressure of R410a. It will just flood back to reduce the compressor life and will greatly reduce the system capacity.
In 1987 an agreement called the Montreal Protocol was signed to begin the worldwide phase out of ozone-depleting CFCs and in 1992 HCFCs were added. In 2010, manufacturers were no longer able to produce new equipment designed with R22 and at the end of 2020, production and import of R22 will be eliminated.
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.
Freon (R-22) and Puron (R410A) both go through the same cooling process but they have differences. Puron is much more environmentally friendly. It is non-ozone depleting and it is also chlorine free. However, at the moment it is a little more expensive than Freon.
