Reading the July Shipment Data: What a 20.1% Equipment Jump Means for Refrigerant Planning
US manufacturers shipped 916,830 central air conditioners and air-source heat pumps in July 2026, 20.1% more than the 763,443 units shipped in July 2025. July is already one of the industry's peak months, so a jump of that size is not a rounding artifact. It changes the arithmetic for anyone who has to buy, store, service or recover refrigerant over the next decade.

R-744 in Small-Format Retail: Where Transcritical CO2 Fits and Where It Does Not
Below the critical temperature, a CO2 system works the way a conventional vapor-compression system works: the high-side heat exchanger is a condenser, refrigerant condenses at a saturation temperature corresponding to its pressure, and subcooling is available in the usual way.

Refrigerant Selection for High-Density Data Center Cooling
Direct-to-chip cooling runs warmer facility water than legacy air cooling does, which is the point: a higher chilled water setpoint means less lift across the compressor and better efficiency, and more hours where the chiller can be unloaded or bypassed entirely in favor of free cooling. Refrigerant selection interacts with this directly, because volumetric capacity and the shape of the pressure-enthalpy envelope determine compressor sizing and how gracefully the machine hand

After GWP: Why TFA Is the Next Number Worth Knowing
For most of the past decade, refrigerant selection has revolved around one number: global warming potential. The AIM Act step-down and EPA’s Technology Transitions rules made GWP the threshold every new system has to clear. More recently, PFAS has entered the conversation, and with it a broader question: what happens to a refrigerant after it leaves the system?

The science of R-4106A: engineering A2L performance with non-flammable transport and storage
R-4106A is FluoroFusion's next-generation refrigerant blend, developed through proprietary chemistry as an alternative to R-454B in equipment designed and listed for it. It maintains A2L classification characteristics for equipment application while also being classified as non-flammable for transportation under U.S. Department of Transportation (DOT) regulations, simplifying handling and logistics. Thermodynamic cycle analysis run in NIST REFPROP across nine standard operati

Unlocking the circular economy: FluoroFusion's formal AIM Act petition to the EPA
On December 18, 2025, FluoroFusion Specialty Chemicals filed a petition under Subsection (i)(3) of the American Innovation and Manufacturing (AIM) Act and 40 CFR § 84.62, calling on the U.S. Environmental Protection Agency (EPA) to amend the Technology Transitions Rule (TTR). EPA lists the petition on its Petitions for Reconsideration and Judicial Review page under AIM Act subsection (i), with a status of Under Review, and hosts the filed petition on epa.gov. Status shown as

36 Fires, One Common Thread: Refrigerant Nobody Could Vouch For
Our VP of Sales, Don Sobocinski, posted a refrigerant safety bulletin on methyl chloride that’s worth expanding on. His point: you should be able to trace every cylinder you open back to a source that will stand behind it. A report out of South Korea this month shows exactly what happens when nobody asks that question. What Korea’s fire agency found On September 2, South Korea’s National Fire Agency announced that it had tied a run of air conditioner fires to illegal refriger

The Silent Killer: How High Moisture in Refrigerant Destroys HVAC Equipment (And Puts Your Business at Risk)
The HVAC industry is currently flooded with sub-par refrigerant. On the surface, cheap or improperly refined gas seems like an easy way to protect margins in a competitive market. The system charges up fine, pressures look normal, and the unit cools.
However, hidden inside that gas is a silent killer: excessive moisture.
