All new systems will use either R-32 or R-454B HVAC Refrigerant, replacing the older R-410A version. It might seem like a great bother until you understand the purpose of these refrigerants. Air conditioners and heat pumps use a principle called heat transfer, illustrated by an ordinary popsicle.
R-454B. R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in HVAC manufacturing from 2010 until the phase-out is complete in January 2025.
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. Its low density allows for the use of a smaller refrigerant charge.
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.
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.
After months of research, Trane and other HVAC companies are transitioning to using a new refrigerant for our residential products called R-454B. R-454B is a blend of R-32, an HFC, and R-1234yf, an HFO.
The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either. This will contaminate the system, and the R22 will not evaporate under the higher suction pressure that R410A requires.
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems. At 909, RS-53 has a GWP that is effectively 56% lower than R410a. Additionally, RS-51 (R470B) has a GWP of 717 which is 80% lower than R404a, R507 and half of R448A and R449A.
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.
Trane is phasing in the transition to R-454B in 2024, starting with the adoption of R-454B refrigerant in its residential products, beginning with the XR15 SEER2 heat pump.
In general, air conditioners that are properly maintained can last 15 to 20 years.
Most Trane products are assembled in the USA! They have manufacturing facilities that assemble central air conditioners and heat pumps in Texas, New Jersey, Georgia, Arkansas, Florida, and Missouri. Even more local, some of the compressors used in Trane A/C's are made in Sidney, Ohio!
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.
R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
R454B: slightly lower capacity than R410A but better efficiency; lower GWP. R32: better efficiency and around 10% more capacity than R410A, depending on the application and system design.
If your system is nearing the end of its life, replacing it before 2025 could be a smart move to avoid higher prices later. Rising Repair Costs: If your system requires frequent repairs or uses R-22 refrigerant, which is already phased out, you might be better off replacing it now.
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 impending phaseout of R-410A, a widely used refrigerant in HVAC systems, marks a huge shift for homeowners and the HVAC industry. Set to take effect on December 31, 2024, this change is driven by global efforts to reduce greenhouse gas emissions and comply with environmental regulations.
If you use R-22 in the same system as R-410a, the compressor is going to be trying to work two different fluids through the same coils as both refrigerants respond differently to different mechanical situations. As you might imagine, this isn't going to go well for your air conditioner or heat pump.
R-410 refrigerant costs $60 per pound on average, but can range from $40 to $75. Keep in mind you cannot purchase R-410A refrigerant without an HVAC pro. As of mid-2024, R-410A refrigerant prices range from $40 to $75 per pound.
2.5 Tons (30,000 BTUs): Suitable for homes ranging from 1,500 to 1,800 square feet. Installation cost ranges from $3,000 to $4,500. 3 Tons (36,000 BTUs): Suitable for homes ranging from 1,800 to 2,100 square feet. Installation cost ranges from $3,500 to $5,000.
After countless hours of research, Trane is transitioning to using R-454B refrigerant and R-32 refrigerant in our residential cooling systems, using a phased-in approach. These refrigerants are more sustainable with a low global warming potential (GWP) and 0 ozone depletion potential (ODP).
Basically, federal standards will require a new type of refrigerant to be used in brand-new home HVAC systems. Right now, cooling systems are required to use HFC and HCFC refrigerants, like R410a. The new guidelines will require A2L refrigerant to be used instead for all systems manufactured after a certain time.
R-22 refrigerant prices range from $90 to $250 per pound. Since you'll need between 6 and 12 pounds to refill a home AC, costs can reach between $660 and $2,400 for a refill of R-22 refrigerant. U.S.
