Starting in January 2025, no new HVAC systems will use R-410A refrigerant. Instead, most residential systems will use either R-32 or R-454B refrigerant, both of which have a comparably lower environmental impact.
Of course, we're talking about the well-established R410A and the newly introduced R32. We use the term “refrigerant” to refer to several types of gases that we use as cooling agents in air conditioners and other similar devices.
What are my options for replacing R-410A? Because there are no retrofits for R410A, a replacement is needed. The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B. Forane® R-32 can be used in new equipment designed specifically for mildly flammable refrigerants as a replacement for R-410A equipment.
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.
Can a R32 system be charged with R410A or vice versa? Daikin The simple answer is no. The operating characteristics of both refrigerants are different and the systems have been designed accordingly. One example is that the compressor runs hotter for a R32 system so the compressor design will be different.
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.
As a part of this plan, R-410A refrigerant will be gradually phased out of production. The objective is to replace it entirely with A2L refrigerants over time. Starting in 2025, HVAC manufacturers can no longer make equipment that requires R-410A.
Only Section 608 certified technicians can purchase refrigerants intended for use with stationary refrigeration and air-conditioning equipment.
No. R-454B is NOT a drop-in replacement for R-410A. Although many of the characteristics of R-454B are similar to R-410A, the use of R-454B is restricted by code and regulation to systems for which it was specifically designed.
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.
If the refrigerant used for the existing unit is other than R22, R407C and R410A, the existing refrigerant piping cannot be used. If the existing unit has another use than air conditioning, then existing refrigerant piping cannot be used.
LG leads the way with R32 refrigerant
Now builders can take advantage of the many benefits of R32 refrigerant for their homeowners with LG solutions and technologies as a refrigerant that reliably keeps homes warm and cool.
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.
Yes – universally, new air conditioners and installation will be noticeably more expensive in 2025. You will save significant dollars by buying and installing now.
R1234yf was chosen to replace R134a in all new cars by 2021. Some manufacturers have already made the switch, or the switch is in progress.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
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.
AC units manufactured since 2010 use R410A, and more recently, R32 refrigerants, both are virtually odourless. This means that a smell of rotten eggs is unlikely to be the smell of leaking refrigerant coming from your air conditioner itself.
What is the replacement for R-410A? A lower GWP replacement for R-410A is Forane® R-32. Forane® 32 is a stand-alone third generation refrigerant for new residential and light commercial air conditioning systems, heat pumps and other HVAC applications.
R-454B is the new refrigerant in 2024. By 2025, the EPA's required phaseout of R-410A will be in full effect, with production, importation, and distribution no longer allowed. HVACR businesses must be evaluating their current choices in coolant and ready to make the jump.
Regulatory Changes: As the phase-out continues to restrict production levels and importation, the R-410A price will likely increase. Manufacturing Costs: Fluctuations in the cost of raw materials and manufacturing can also influence the price of refrigerants.
Lennox has chosen R-454B as its 2025 Compliant Refrigerant.
How much does a new HVAC system cost for a 2,000 sq. ft. home? The costs range from $6,224 to $11,434, depending on the system type and installation requirements. Key factors include system size, type, efficiency, and local labor rates.
Several HVAC manufacturers have officially declared upcoming price hikes for 2024, garnering attention as a new wave of increases takes effect. There is a noticeable industry-wide trend of manufacturers elevating the prices of equipment, parts, and supplies.
