For new residential and light commercial central air conditioning equipment, the AHRI petition seeks a regulation requiring that equipment manufacturers use refrigerants with a global warming potential (GWP) of 750 or less in equipment made after Jan. 1, 2025, with the exception of variable refrigerant flow (VRF) equipment, whose deadline would be Jan. 1, 2026.

Building owners and specifiers can experience design flexibility, reduced operational costs and reliable, energy-efficient comfort year-round with variable refrigerant flow (VRF) systems even in extreme cold climates. Modern VRF systems far exceed the capabilities of conventional heat pumps at low outdoor ambient temperatures. They are positioned to replace fossil fuel burning equipment in almost any climate.

The potential for CARB’s GWP limits and implementation dates to align with the EPA’s sector-based controls under the AIM Act create an environment in which a de facto nationwide HFC regulatory framework could actually emerge.

Most often, leaks are the result from improper installation, factory defects, mechanical wear from vibration, or physical damage.

Schoeneck Containers partnered with Thermal Care to specify the Danfoss Turbocor compressor for the scalable capacity, staging abilities, overall efficiency, reliability, and low maintenance requirements.
