Global regulatory changes and refrigerant price volatility are prompting plumbing, heating, and HVAC (SHK) contractors to reconsider procurement strategies and retrofit timelines. The European Union (EU) and United States (U.S.) have enacted stricter low-GWP refrigerant rules, with ongoing supply constraints driving up material costs and complicating retrofit projects.

Background

The EU's revised F-Gas Regulation (Regulation 2024/573) bans refrigerants with a global warming potential (GWP) of 150 or higher in new packaged air-conditioning units from January 1, 2027. Similar capacity-based GWP limits for chillers and split systems will follow by 2029. The intent is to reduce hydrofluorocarbon (HFC) use by 30% in 2024 and another 30% by 2029, continuing toward stricter thresholds. The updated regulation prohibits high-GWP refrigerants in packaged AC units from January 1, 2027, and applies capacity-based GWP limits for chillers and split systems through 2029 {{cite:}}. The EU Commission targets a 98% HFC reduction by 2048, with a sharp phase-down starting in 2024-2026. {{cite:}} In the U.S., the EPA's Technology Transitions rules prohibit the manufacture and installation of high-GWP systems. Newly installed systems must use refrigerants with GWP under 700, except for certain data-center cooling equipment, which has compliance extensions through 2027-2029. {{cite:}}

Details

Low-GWP refrigerants remain scarce. European markets rely on imports for hydrofluoroolefins (HFOs) and natural alternatives, meeting only 55% of demand. Fluorspar, a key HFO feedstock, rose 22% in price following Chinese export controls. {{cite:}} Market fragmentation has raised HFO-1234yf costs by 40-60% over traditional refrigerants. {{cite:}} Retrofit projects face delays as technician certification for flammable alternatives remains limited, pushing project timelines back by three to six months in markets such as the U.S., Australia, and Canada. {{cite:}}

Forecasts estimate the low-GWP refrigerant market will grow from USD 2.33 billion in 2024 to USD 3.52 billion by 2032, representing a 6.2% compound annual growth rate (CAGR) driven by Kigali Amendment targets and F-Gas mandates. {{cite:}} Strategic investments are growing in low-GWP systems, especially those using natural refrigerants such as CO₂ and ammonia, in industrial and automotive sectors. {{cite:}}

Outlook

SHK contractors must navigate compliance with phase-down schedules, train personnel on A2L and natural refrigerants, secure alternative supply chains, and manage retrofit cost premiums. Market forecasts indicate continued price volatility through 2026 as production capacity increases. Prices may stabilize post-2026, but low-GWP alternatives are expected to remain costlier than legacy HFCs. Procurement optimization and proactive retrofit planning will be critical as regulatory and market pressures intensify.
