Refrigerants

The proposed Significant New Alternatives Policy Rule 27 would list several lower-GWP substitute refrigerants as acceptable, subject to use conditions, for residential and light commercial air conditioners and heat pumps, chillers, household refrigerators and freezers, motor vehicle air conditioners, and fire suppression and explosion protection.

Here’s what HVAC contractors and techs had to say on social media in our latest HVAC Talkback regarding the extension of the R-410A deadline.

Starting next year, R-410A VRF systems will be phased out as new equipment transitions to low-GWP refrigerants. Contractors will play a vital role in helping end users understand their options.

Another refrigerant transition is inevitable, as innovation drives HVAC forward. But without clearer communication and coordination next time, contractors’ patience — and trust — may finally run out. 

A recent study has uncovered significant opportunities for year-round energy savings on CO2 refrigeration systems through the use of low-side strategies. 

The refrigerant shortage is over. Its aftershocks are still rippling through the industry. 

As A2L VRF systems roll out in the U.S., contractors can save time and headaches by applying proven lessons learned from Europe’s earlier transition.
