What are you actually seeing on price, availability, and safety in Canada?

Past 60 days (Ontario + AB), here’s what I’m actually seeing:

- **Availability:** A2L (R-454B/R-32) units from the big brands are here; typical **1–3 week** lead times. **R-410A close-outs** are same-day if the match is in stock.

- **Price:** New A2L platforms are **~10–20% higher** than last year’s R-410A. Close-outs can save **$1k–$2k** installed, but future parts/refrigerant will run pricier.

- **Safety on-site:** “Mildly flammable” hasn’t been an issue—follow the book and it’s fine: nitrogen while brazing, A2L-rated recovery, tight leak checks, labeling. No incidents on my crews.

- **Practical gotchas:** Expect a **new matched coil/air handler** and sometimes a **new lineset** ; a few AHJs are fussier on permits/clearances.

**My take:** If you can wait a couple weeks, go **A2L** for future-proofing. If the house is roasting and a solid **R-410A close-out** is sitting on the shelf, grab the discount and get cool now.
