R-32 Refrigerant: 2026 Buying Guide for Contractors
R-32 is one of the two refrigerants replacing R-410A in new residential and light-commercial air conditioners, heat pumps and ductless mini-splits. If you're a tech or contractor installing or servicing R-32 equipment, this guide covers what R-32 is, what changes on the job because it's an A2L, how it compares with R-454B and R-410A, and how to buy it by the pallet. Quick answer: R-32 (HFC-32, difluoromethane) is a single-component refrigerant with a GWP of about 675, roughly two-thirds lower than R-410A. It's classed A2L (lower toxicity, mildly flammable) and has zero ozone depletion potential. It is not a drop-in for R-410A or R-22 systems. Use it only in equipment designed and rated for R-32. Absolute Refrigerants sells virgin, factory-sealed R-32 in 20 lb cylinders by the quarter, half or full pallet, with free pallet freight. Bulk pricing drops as you buy more. See live R-32 pallet pricing What R-32 is Chemistry: pure difluoromethane (CH2F2), also sold as HFC-32. It is not a blend. GWP: about 675, versus about 2,088 for R-410A. Safety class: A2L under ASHRAE 34. Ozone depletion potential: zero. Pressures: slightly higher than R-410A, with higher discharge temperatures, which is one reason the equipment has to be [...]
R-454B Refrigerant: 2026 Buying Guide for the A2L Transition
R-454B is the refrigerant going into most new residential and light-commercial air conditioners and heat pumps that used to be built for R-410A. If you're a tech or contractor installing that new equipment, this guide covers what R-454B is, what changes on the job because it's an A2L, how it compares with R-410A and R-32, and how to buy it by the pallet. Quick answer: R-454B is a blend of R-32 and R-1234yf with a GWP of about 466, roughly 78% lower than R-410A. It's classed A2L (lower toxicity, mildly flammable). It is not a drop-in for R-410A or R-22 systems. Use it only in equipment designed and rated for R-454B. Absolute Refrigerants sells virgin, factory-sealed R-454B in 20 lb cylinders by the quarter, half, or full pallet, with free pallet freight. Bulk pricing drops as you buy more, so a full pallet has the lowest price per cylinder. See live R-454B pallet pricing What R-454B is Composition: R-32 (68.9%) and R-1234yf (31.1%). Trade names: Opteon XL41 (Chemours) and Puron Advance (Carrier). The cylinder label should read R-454B. GWP: about 466, versus about 2,088 for R-410A. Safety class: A2L under ASHRAE 34. Pressures: close to R-410A, slightly lower, so it [...]
R-407C Refrigerant: 2026 Buying Guide for Techs and Contractors
R-407C is one of the most common HFC refrigerants in air conditioning, and one of the main options techs use when an R-22 system gets converted instead of replaced. If you service R-407C equipment, or you're weighing an R-22 retrofit, this guide covers what R-407C is, where it's used, what a retrofit involves, how it compares with R-22 and R-410A, and how to buy it. Quick answer: R-407C is a zeotropic blend of R-32, R-125 and R-134a. It's classed A1 (lower toxicity, non-flammable), has zero ozone depletion potential and a GWP of about 1,774. It runs at pressures close to R-22, which is why it's used to retrofit some R-22 systems, but it is not a drop-in, and it is never used to top off an R-22 system. It uses POE oil and should be charged as a liquid. Absolute Refrigerants sells factory-sealed, 100% virgin R-407C in 2 lb cylinders and in 25 lb cylinders by the quarter, half or full pallet. See live R-407C pricing What R-407C is Chemistry: a blend of R-32 (23%), R-125 (25%) and R-134a (52%) by weight. It is an HFC, so it contains no chlorine.

5 Reasons Why Choosing the Right Refrigerant is Critical for Energy Efficiency
5 Reasons Why Choosing the Right Refrigerant is Critical for Energy Efficiency- Absolute Refrigerant Want to know the 5 Reasons Why Choosing the Right Refrigerant is Critical for Energy Efficiency? Choosing the right refrigerant for your HVAC system is critical for energy efficiency. Refrigerants are essential for cooling and heating systems, and the type of refrigerant used can significantly impact the system's energy efficiency. This article will explore the five reasons why choosing the right refrigerant is critical for energy efficiency. Efficiency The efficiency of a refrigerant is critical for energy efficiency. The efficiency of a refrigerant is measured by its ability to absorb and release heat. The higher the efficiency of a refrigerant, the more energy-efficient the HVAC system will be. Choosing a high-efficiency refrigerant can lead to significant energy savings over time. For example, the use of a high-efficiency refrigerant in a central air conditioning system can reduce energy consumption by up to 20%. Environmental Impact The environmental impact of a refrigerant is another important factor to consider when choosing a refrigerant. Some refrigerants, such as R-22, have been found to significantly impact the environment due to their high global warming potential. Choosing a refrigerant with a low [...]
What Factors Should You Consider When Choosing a Refrigerant?
What Factors Should You Consider When Choosing a Refrigerant?- Absolute Refigerant Each application has a unique set of requirements, so there is no universally applicable refrigerant solution. It is essential to concentrate on choosing the proper refrigerants for each application based on evaluating the whole. Absolute Refrigerants considers it essential to thoroughly evaluate four fundamental criteria in this entire assessment: safety, environmental impact, energy efficiency, and cost-effectiveness. Safety During the entirety of the equipment's existence, a refrigerant must be safe to use. Recycling, recovery, servicing, use, installation, storage, and transportation are all under this category. This implies that for each kind of application, potential risks like toxicity or flammability traits and the chance of human mistakes must be evaluated. While non-flammable and low-toxicity refrigerants may improve safety, they might not be the best choice for the environment. Also, while some refrigerants may be safe enough for one type of equipment, they may not be for others. For this reason, comprehensive risk analyses are required for each application. Environmental Impact The environmental impact of a refrigerant is a key factor to be taken into account. The CO2 equivalent of a refrigerant, which is the amount of refrigerant multiplied by its global [...]
R-454A Refrigerant: 2026 Guide, R-454A vs R-454B and R-404A
R-454A is one of the low-GWP refrigerants built to take R-404A's place in new commercial refrigeration, and it's easy to confuse with R-454B. They share most of a name and the same two ingredients, but they're built for different equipment. This guide covers what R-454A is, how it performs against R-404A, how it differs from R-454B and R-454C, where EPA allows it, and how to buy it by the pallet. Quick answer: R-454A (Chemours Opteon™ XL40) is a blend of 35% R-32 and 65% R-1234yf. It's classed A2L (lower toxicity, mildly flammable), has zero ozone depletion potential and a GWP of 239 (IPCC AR4). It's designed to replace R-404A in new low- and medium-temperature commercial refrigeration, not to retrofit existing R-404A systems. R-454B is a different blend for air conditioners and heat pumps. We sell 100% virgin R-454A in 25 lb cylinders by the quarter, half or full pallet, with free freight and live pricing. See R-454A 25 lb cylinders and live pricing What R-454A is Chemistry: 35% R-32 (an HFC) and 65% R-1234yf (an HFO) by weight. No chlorine, so its ozone depletion potential is zero. Safety class: A2L under ASHRAE 34. "A" means lower toxicity; "2L" means mildly [...]
