Why R-22 and R-410A Refrigerants Are Being Phased Out – And What It Means for Ontario Homeowners

Let’s start with the good news: if you’re reading this, you probably care about what goes into your HVAC system—and what comes out of it. That awareness matters, especially as older refrigerants are phased out across Ontario. 

Now, for the not-so-good news: if your air conditioner or heat pump still runs on R-22 (or even R-410A), you could soon be facing skyrocketing repair costs—upwards of $100 to $250 per pound of refrigerant—or worse, a full system replacement. 

That’s because two of the most common refrigerants used in older HVAC systems—R-22 and now even R-410A—are being phased out due to their environmental impact. While the reason behind the shift is important, what really matters for homeowners is this: you’ll be paying more and getting less if your system uses these outdated refrigerants. 

So, what does this all mean for your comfort—and your wallet? Let’s break it down. 

What Is R-22 Refrigerant, Anyway? 

R-22 is a type of hydrochlorofluorocarbon (HCFC) refrigerant used in air conditioners, heat pumps, refrigerators, and freezers. It’s a chemical compound that rapidly evaporates and condenses, making it effective at absorbing heat and cooling your home—especially on those sweltering summer days in Mississauga or Kitchener. 

Sounds useful, right? Well, not so fast.

The Problem with R-22: It’s a Climate Villain 

Here’s the issue: R-22 is terrible for the environment. When it leaks into the atmosphere, it releases chlorine, which destroys the ozone layer—that thin, vital shield protecting us from harmful UV rays. It also has a high Global Warming Potential (GWP), meaning it traps heat and contributes to climate change. 

Over time, this silent saboteur helped punch a hole in the ozone layer. R-22 and its chemical cousins (like CFCs and other HCFCs) are largely responsible for the infamous ozone hole over Antarctica. 

Why Is R-22 Being Phased Out? 

The short answer: Because it’s toxic for the planet. 

The long answer: A global environmental movement led to the Montreal Protocol, signed in 1987. Canada, the U.S., and nearly every other country committed to phasing out ozone-depleting substances like R-22. And in true Canadian fashion, we followed through. 

Key Phase-Out Dates: 

• 2010: Canada and the U.S. banned the production of new HVAC systems using R-22. 
• 2020: Production and import of R-22 refrigerant were officially banned. 
• 2030: All use of R-22 in Canada—including recycled stock—will be completely prohibited. 

If your AC or heat pump was installed before 2010—especially in older homes in Hamilton, London, or Toronto—there’s a chance it’s still running on R-22. And that’s a problem. 

What Does This Mean for Ontario Homeowners? 

Here’s where it hits home: While R-22 isn’t illegal to use yet, it’s only available through recycled stock, and the prices are sky-high—think $100 to $250 per pound. 

If your older unit leaks refrigerant, topping it off is going to cost you. And soon, you may not be able to find R-22 at all. 

Plus, servicing these older systems is expensive and requires certified HVAC professionals. Even then, it’s like patching a leaky boat—you’ll be sinking again soon. 

Should You Repair or Replace? 

We get it—replacing an entire AC system isn’t exactly on your dream-spending list. But if your unit still runs on R-22, the clock is ticking. 

Here’s a quick guide: 

✅ Repair if: Your unit is relatively young (under 12 years), the issue is minor, and you have access to R-22.
❌ Replace if: It’s over 12 years old, inefficient, or repair costs are piling up. Upgrading to a modern, energy-efficient unit will save you long-term. 

The good news? LG Home Comfort makes that switch easy—and eco-conscious. 

What About R-410A? Isn’t That the Safe Replacement? 

Yes—and no. 

R-410A, a common R-22 replacement, is chlorine-free and has zero ozone-depleting potential. It was the gold standard for over a decade. 

However, under the Kigali Amendment to the Montreal Protocol and the American Innovation & Manufacturing (AIM) Act, R-410A is also being phased out due to its high GWP. The global HVAC industry is now transitioning to even greener alternatives. 

⚠ R-410A Phase-Out Timeline: 

• 2025: New residential and light commercial systems can no longer use R-410A in the U.S. (Canada is expected to follow a similar path). 
• 2030–2036: Full phase-out of R-410A in all new equipment. 
• Existing systems: Can still be serviced, but R-410A will become more expensive and less available over time. 

The Alternatives: Meet the New Cool Kids 

Modern HVAC systems now use eco-friendly refrigerants that are cleaner and more efficient: 

🌿 R-32
67% lower GWP than R-410A. It’s quickly becoming Ontario’s preferred choice for new installations. Cools faster, uses less energy, and leaves a lighter carbon footprint. 

💧 R-454B & R-290 (Propane)
Ultra-low GWP and zero ODP refrigerants. These next-gen coolants are leading the future of sustainable cooling. 

🧪 R-466A
A non-flammable HFO blend with low GWP that’s gaining traction as an R-410A alternative in commercial applications. 

At LG Home Comfort, we don’t just follow trends—we lead with green solutions. That’s why none of our systems use R-22, and we’re already embracing the most advanced refrigerants available today.
