Is R-410A banned in Canada in 2026?

No. R-410A is not banned in Canada in 2026. Production and import are being phased down gradually, but the refrigerant itself remains legal for service and repairs. New equipment can still be manufactured with R-410A, though manufacturers are transitioning to newer refrigerants over the next several years. Your existing R-410A system will continue to work normally and can be serviced for many years. The R-22 phase-out (which began in 2010) took over a decade to fully impact homeowners — R-410A will follow a similar timeline.

Will my R-410A air conditioner become obsolete?

No. Your R-410A system will continue to work normally. Service and repairs will be available for many years — likely 10-15 years or more. The R-22 phase-out (which began in 2010) took over a decade to fully impact homeowners. R-410A will follow a similar long timeline. There is no reason to replace a working R-410A system because of the 2026 refrigerant changes. Call (647) 550-4220 if you have specific concerns about your system's age or condition.

Should I replace my working R-410A system now?

No. If your system is working properly, there is no reason to replace it because of refrigerant changes. R-410A will be serviceable for years. Replace when your system reaches the end of its natural life (10-15 years) or when repair costs become uneconomical — typically when repair exceeds 50% of replacement cost. At Hawana, we follow the 50% rule: if a repair costs more than half of a new system, we recommend replacement. Otherwise, we repair. Call (647) 550-4220 for honest advice on your specific situation.

What refrigerant should I choose for a new AC or heat pump?

Both R-410A and R-32/R-454B are valid choices in 2026. R-410A is proven, widely supported, and cost-effective. R-32 and R-454B offer lower GWP (Global Warming Potential) and may be slightly more efficient. At Hawana, we install and service all three. We'll help you choose based on your budget, future plans, and manufacturer availability. Call (647) 550-4220 for a free consultation. Rebates are available for all qualifying systems regardless of refrigerant.

Will R-410A repairs become more expensive?

Not in 2026. R-410A is still widely available and competitively priced. Over the next 5-10 years, as production decreases, prices may rise gradually — similar to what happened with R-22. But that's a slow process, and most homeowners will have replaced their systems by then anyway. For now, repairs remain affordable and parts are readily available. Call us for a repair quote if you have concerns: (647) 550-4220.

What are R-32 and R-454B refrigerants?

R-32 and R-454B are the main replacement refrigerants for R-410A. They have much lower Global Warming Potential (GWP): R-32 has GWP of 675 (vs 2088 for R-410A), and R-454B has GWP of 466. Both are slightly more energy-efficient and are being adopted by major manufacturers like Carrier (R-454B), Daikin, and Mitsubishi (R-32). In 2026, they are still relatively new to the Canadian market, with fewer long-term installations in Ontario winters. Both are viable options for new installations.

Are rebates still available for R-410A systems?

Yes. Rebates remain strong for both R-410A and newer refrigerant systems. Qualifying heat pumps are eligible for up to $5,000 through the Canada Greener Homes Grant and up to $7,500 through OHRSP (Ontario Home Renovation Savings Program), regardless of which refrigerant they use. Enbridge Gas rebates of up to $650 are also available for qualifying furnaces. Hawana handles all rebate paperwork at no charge. Call (647) 550-4220 to see what rebates apply to your project.

How long will R-410A be available for repairs?

R-410A will be available for service and repairs for at least 10-15 years. The phase-out is a gradual reduction in production and import, not an immediate ban. The R-22 phase-out began in 2010 and R-22 was still available for repairs well into 2020. R-410A will follow a similar timeline. Your system will not become obsolete overnight. If your R-410A system needs service in 2026, 2027, or even 2030, we'll be able to repair it.

Can I still buy a new R-410A air conditioner in 2026?

Yes. R-410A systems are still widely available and being manufactured in 2026. Major brands continue to offer R-410A equipment alongside newer refrigerant models. If you prefer the proven reliability of R-410A, it remains a valid choice. If you want to future-proof with lower-GWP refrigerants, R-32 and R-454B systems are also available. At Hawana, we offer both options at published prices. Call (647) 550-4220 to discuss which is right for your home.

What should I do if my AC uses R-22 refrigerant?

If your system uses R-22 (older systems, typically pre-2010), you have different considerations. R-22 is now expensive and being phased out. If your R-22 system needs a major repair or is low on refrigerant, replacement with a new R-410A or R-32 system is usually the better financial decision. Call (647) 550-4220 for an honest assessment of your specific system. We'll give you both repair and replacement quotes so you can make an informed choice.

⏱️ 8 min read

You've probably heard about refrigerant changes coming in 2026. Headlines mention "R-410A phase-out" and new refrigerants like R-32 and R-454B. As owner and lead TSSA-certified technician at Hawana HVAC Solutions, I talk to concerned homeowners in London, St. Thomas, Strathroy, Woodstock, and across Southwestern Ontario every week. The good news: R-410A is still fully legal, widely available, and an excellent refrigerant in 2026. Most systems installed today (and many being installed right now) use R-410A, and that will continue for years. Let's break down what's really happening and what it means for your home.

📌 Quick Answer: R-410A is NOT banned in Canada in 2026. You can still repair existing systems, buy new R-410A equipment, and service your AC or heat pump normally. Newer refrigerants like R-32 and R-454B are coming, but there's no rush to replace a working system. Call (647) 550-4220 if you have specific concerns about your system.

The Current Status of R-410A in Ontario – 2026 Reality

R-410A is not banned in Canada or Ontario in 2026. It remains the standard refrigerant for the vast majority of residential air conditioners, heat pumps, and mini-splits being manufactured and installed right now. Here's why homeowners and technicians still trust it:

Proven performance – 20+ years of reliable use in Ontario's cold winters and humid summers
High efficiency – works well with modern high-SEER systems
Plenty of supply – parts, refrigerant, and trained technicians are widely available
Cost-effective repairs – no premium pricing for R-410A components yet

✅ R-410A — Still the Standard

Widely available. Proven in Ontario conditions. Most systems use it. Repairs are straightforward. No need to replace a working system.

✓ Best for most homeowners in 2026

🔄 R-32 — Emerging Replacement

Lower GWP (675 vs 2088). Slightly more efficient. Newer — fewer long-term installations in Ontario cold winters. Good option for new builds.

✓ Good for new installations

🔥 R-454B — Alternative Option

Very low GWP (466). Similar performance to R-410A. Still new to Canadian market. Technician training ongoing. Available through select manufacturers.

✓ Future-proof option

What Is Actually Changing in 2026?

Canada (following U.S. EPA rules) is gradually reducing production and import of high-GWP (Global Warming Potential) refrigerants like R-410A. This means:

New manufactured equipment will increasingly use lower-GWP refrigerants (R-32, R-454B) starting in 2025–2026
R-410A will still be allowed for service/repairs of existing systems for many years (similar to the R-22 phase-out timeline that took over a decade)
Eventually R-410A will become more expensive and harder to source — but we're not there yet in 2026

💡 Think of it like R-22: When R-22 was phased out starting in 2010, it remained available for repairs for over 10 years. R-410A will follow a similar long transition. Your system will not become obsolete overnight.

Refrigerant Comparison: R-410A vs R-32 vs R-454B

Refrigerant	GWP (Global Warming Potential)	Efficiency	Availability in 2026	Best For
R-410A	2,088	High (baseline)	Widely available	Existing systems, cost-effective repairs
R-32	675	Up to 10% higher	Growing availability	New installations, Mitsubishi/Daikin systems
R-454B	466	Similar to R-410A	Limited (Carrier, Bryant)	Future-proof new systems

Newer Refrigerants: R-32 and R-454B – Where They Stand in 2026

R-32 and R-454B are the main replacements. They have much lower GWP and are slightly more efficient in some conditions. However, in Southwestern Ontario in 2026 they are still relatively new:

Fewer real-world installations compared to R-410A
Limited long-term customer feedback in our cold winters
Technician training is ongoing — not every company is fully experienced yet
Parts availability is good but not as widespread as R-410A

We'll know much more about their long-term reliability in Ontario conditions in the coming years. For now, R-410A remains the safe, proven choice for most homeowners.

What This Means for London Homeowners in 2026

If your current AC or heat pump uses R-410A → You can repair it normally. No need to replace early. Parts and refrigerant are widely available.
If buying new → You can still choose R-410A systems (still widely sold & installed). R-32/R-454B systems are also available if you want to future-proof.
If considering future-proofing → Newer R-32 or R-454B models are good options, but not urgent yet. R-410A will be serviceable for many years.
Rebates remain strong for both – up to $5,000 for qualifying heat pumps regardless of refrigerant choice.
