HFC to HFO refrigerant transition in Quebec

Canada has committed to reducing HFC emissions by 85% by 2034 under the Kigali Amendment. For Quebec HVAC-R techs, that changes how the work gets done.

The Canadian timeline

• 2024 — HFC consumption levels frozen
• 2029 — 40% reduction
• 2034 — 85% reduction

In practice: high-GWP refrigerants (R-404A, R-507A) will become more expensive and harder to find.

Common replacements

R-404A (GWP 3922) → R-449A (GWP 1397)

The most frequent swap in commercial refrigeration. R-449A is a near-direct drop-in:

• Compatible with existing POE oil
• Slight capacity loss (5-10%) — adjust the expansion valve
• Similar operating pressures

R-410A (GWP 2088) → R-32 (GWP 675)

In air conditioning, R-32 is gradually replacing R-410A:

• Caution: not a drop-in, requires a system designed for R-32
• Classified A2L (mildly flammable) — training required
• Better energy efficiency

R-134a (GWP 1430) → R-513A (GWP 631)

For medium-temperature refrigeration:

• Direct drop-in for most systems
• Compatible with existing oils and seals

Impact on technicians

• Training — A2L refrigerants require specific training (flammability)
• Tooling — leak detectors compatible with HFOs
• Logbook — documenting every refrigerant handling is more important than ever
• Opportunity — converting existing systems = service contracts

Practical advice

Start offering R-404A → R-449A conversions to your existing customers. It's a value-added service, it prepares your customers for the regulations, and it generates billable work.
