INDIANAPOLIS — Against the backdrop of HVAC industry regulatory changes, Carrier is once again taking the opportunity to redesign its systems from the inside out, putting dealers, technicians, and homeowners at the forefront of innovation, the company said in a recent press release.

Carrier’s newest portfolio includes an entire lineup of ductless systems; the company is expanding offerings, incorporating new platforms and technologies, and integrating R-454B, Carrier’s refrigerant of choice, known commercially as Puron Advance.

“The 2025 refrigerant phasedown set the timeline, but improving serviceability and installation while maximizing energy efficiency was the priority,” said Tyler Oehlman, associate director of ductless and VRF product management at Carrier. “We’re not just adding to the lineup, we’re improving the full portfolio and helping to establish ductless as a viable, sometimes even preferred, home heating and cooling solution for North America.”

Changes to the Carrier ductless portfolio include refrigerant-specific components, new control technologies, and additions to the Carrier Crossover portfolio. Crossover products provide a system that maintains the traditional ducted heating and cooling characteristics while leveraging elements of ductless technology, the company said.

Enhancements made to the ductless lineup include:

• Refrigerant leak-detection sensors, included in most indoor units.

• Enhanced compressors in select equipment.

• One more connection port added to multi-zone condensers.

• New wireless and wired controllers, with a built-in wi-fi option.

• User-friendly and easy-to-read display screens.

• Remote upgrades with over-the-air updates.

Additions to the Crossover lineup include a new air-handler unit with multi-poise design configuration, a single fan chassis for up to 5 tons, and an available larger service port.
