Air conditioners are essential, especially during the hot months, but not everyone realizes that the real magic behind your cool home is the home AC refrigerant working inside the system. Without the right AC refrigerant, your AC wouldn’t be able to pull heat from the air and keep your space comfortable. But here’s what most people don’t know — not all types of AC refrigerant are the same. As technology evolves, environmental concerns grow, and regulations tighten, choosing the right home AC refrigerant has become more crucial than ever.

Let’s dive into the basics of AC refrigerants, why they matter, and how to make sure you’re using the best one for your air conditioning system.

Why Refrigerants Matter More Than You Think

Refrigerants are chemicals that flow through the coils of your air conditioner in Canada, absorbing heat from inside your home and releasing it outside. It’s a simple process that keeps you cool when it matters most. However, not every AC refrigerant does this job equally.

Some, like the once-popular R-22, are being phased out due to their environmental impact, while newer, more efficient types of AC refrigerant are designed to minimize energy use and lower emissions. So, choosing the right home AC refrigerant can affect everything from how cool your home stays to how much you pay in energy bills and how environmentally friendly your system is.

The Different Types of AC Refrigerants You Should Know About

When choosing a gas furnace for your garage, it’s easy to get overwhelmed by all the specs and features. But here are the ones that really matter:

R-22 (Freon)

You’ve probably heard of Freon. It used to be the go-to refrigerant in pretty much every AC system. But here’s the thing: Freon, or R-22, is no longer manufactured or imported in Canada or the U.S. because of its harmful impact on the ozone layer. If your AC system still uses R-22, you’re running on borrowed time. Once your system needs a recharge or repair, it’s going to cost you more because the supply is limited and prices have shot up.

Even though you can still service older units that use R-22, it’s only a matter of time before the high costs of keeping it running outweigh the benefits. Most people are now switching to more eco-friendly and efficient options.

R-410A (Puron)

R-410A, often branded as Puron, is the most common refrigerant in newer AC systems. It’s a much greener option than R-22, both in terms of environmental impact and efficiency. R-410A doesn’t harm the ozone layer like R-22 does, which is why it’s become the standard for residential AC systems installed after 2010.

But here’s what really makes R-410A stand out — it operates at a higher pressure, which helps your air conditioner cool more effectively while using less energy. This means lower utility bills, and who doesn’t want that? Plus, systems that use R-410A tend to last longer because the refrigerant itself is more stable.

If you’re thinking about upgrading your AC system, this is likely the refrigerant you’ll be using. However, as good as it is, there are newer, even more efficient refrigerants coming into the market.

R-32

R-32 is one of the newer players in the game and is becoming increasingly popular, especially in energy-conscious countries like Canada. Why? It has a lower global warming potential (GWP) than R-410A, which means it’s an even more environmentally friendly choice. In fact, it’s about one-third more efficient than R-410A when it comes to cooling, making it ideal for people looking to lower their carbon footprint without sacrificing comfort.

Another great thing about R-32 is that it uses less refrigerant to achieve the same cooling power, which translates to even lower energy costs. The only downside? It’s not as widespread in North America yet, but that’s changing fast. More HVAC manufacturers are shifting to R-32 due to its environmental benefits and efficiency.

R-134a

While R-134a isn’t as common in residential AC systems, you might still find it in smaller units, such as portable air conditioners or dehumidifiers. It’s worth mentioning because, while efficient, it doesn’t offer the same energy-saving benefits as R-32 or R-410A. Its global warming potential is also higher than R-32, so it’s slowly being phased out in favor of better alternatives.

If your system uses R-134a, it’s not necessarily bad, but it might be worth considering a change if you’re looking to upgrade for efficiency or environmental reasons.

R-32 is a newer refrigerant that is gaining popularity because of its lower global warming potential (GWP) and higher efficiency compared to older refrigerants like R-410A. It is about one-third more efficient at cooling than R-410A, meaning it uses less refrigerant to achieve the same cooling power. This not only reduces energy costs but also makes it a more environmentally responsible option. R-32 also has a lower GWP, which reduces its contribution to global warming. While it’s not yet as widespread in North America, it’s quickly becoming the refrigerant of choice in energy-conscious markets, especially as HVAC manufacturers shift to more eco-friendly options.

In some cases, it’s possible to retrofit an older AC system that uses R-22 to work with a newer refrigerant, but it’s not always recommended. Retrofitting involves modifying the existing system, which can be costly and might not provide the same efficiency as a new system built for modern refrigerants like R-410A or R-32. Additionally, not all systems are compatible with retrofitting, and the performance may be compromised if the new refrigerant doesn’t match the system’s pressure and design specifications. In most cases, upgrading to a new, energy-efficient AC system is a better long-term investment, especially when considering the rising costs of R-22 and the improved performance of newer refrigerants.

Global Warming Potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere compared to carbon dioxide over a specific period, usually 100 years. The higher the GWP, the more the substance contributes to global warming. When choosing a refrigerant, it’s important to consider GWP because refrigerants with a lower GWP, like R-32, have less impact on climate change. Older refrigerants like R-22 and R-134a have higher GWPs, meaning they contribute more to global warming when leaked into the atmosphere. As environmental regulations tighten, choosing a refrigerant with a low GWP helps reduce your carbon footprint and keeps your AC system compliant with future standards.

If your AC system leaks refrigerant, it can significantly impact its cooling performance. The system won’t be able to effectively absorb and release heat, making it harder to cool your home, and you may notice higher energy bills. Leaking refrigerant also poses environmental risks, especially if your system uses older, ozone-depleting refrigerants like R-22. If you suspect a refrigerant leak, it’s essential to contact an HVAC technician as soon as possible. Depending on the type of refrigerant, recharging or repairing the system could be costly, especially for systems using phased-out refrigerants. In some cases, it may be more cost-effective to replace the system with one that uses a more efficient and environmentally friendly refrigerant like R-410A or R-32.

Yes, using the wrong refrigerant in your AC system can cause significant damage. Air conditioners are designed to operate with a specific refrigerant, and using a different one can affect the system’s pressure levels, cooling capacity, and overall performance. For instance, switching from R-22 to R-410A without proper modifications can lead to mechanical failure because the two refrigerants operate at different pressures. Even worse, it could void your warranty or lead to costly repairs. Always consult a professional HVAC technician before attempting to switch or recharge refrigerants to ensure your system remains in good working order and operates efficiently.

To determine which refrigerant your AC system uses, check the label on the outdoor unit of your air conditioner. This label should include details about the refrigerant type, such as R-22, R-410A, or R-32. If you can’t find the label or if it has worn off, you can also refer to the user manual or contact the manufacturer with your model number. If your system is older and installed before 2010, it’s more likely to use R-22, while newer systems typically use R-410A. If you’re unsure, a professional HVAC technician can also inspect the unit and confirm the refrigerant type for you. Knowing which refrigerant your system uses is crucial for maintenance, repairs, and potential upgrades.
