York YMC2 chiller "Our York YMC2 chiller continues to gain market share. It currently is at 17%, and we're hoping to get 20% to 25% of that segment. It's more efficient, and you win when you can provide a more efficient chiller that reaches a broader audience," Jackson said. JCI's new VRF product, SmartFlex — the first fruit of the Hitachi joint venture — is a ductless and modular HVAC solution that heats and cools multiple building zones to increase energy savings, improve occupant comfort, and lower construction costs. "We've developed new digital selection and configuration tools to help owners, operators and consultants compare heating and cooling solutions," Jackson said.
