Can I use R290 instead of R134a? In short, yes. You can use R290 instead of R134a because R290 serves more advantages than R134a. For example, R290 has a lower GWP. It is more energy efficient. It also has less impact on the environment and higher coolant capacity.
Here, I will discuss all the details of R290 and R134a, their pros and cons, and the other relevant things. So keep reading.
Can I Use R290 Instead Of R134a?
The answer isn’t easy to give in a few words, or with a yes, or no. Theoretically, you might have a chance to use R290 instead of R134a.
They are both coolants, but they have different features. R290 is good for the planet, but it is dangerous because it can burn.
R134a is not dangerous, but it is harmful to the air we breathe. You need to change your cooling system if you want to use R290 instead of R134a. You also need to be careful with R290 and follow the rules.
Is R290 The Same As R134a?
No, R290 and R134a are not the same. They are both refrigerants, but they have different chemical formulas, properties, and applications. R290 is also known as propane, while R134a is also known as tetrafluoroethane.
Comparing Refrigerant Options: R290 vs R134a
Refrigerants are essential substances used in cooling systems, but they can vary greatly in their properties and environmental impacts. Two common options are R290 (propane) and R134a, which have key differences that equipment owners must weigh up.
R290 vs R134a
Before further discussion, let’s see the comparison between these two coolants.
| Properties | R290 (Propane) | R134a |
| Type | Hydrocarbon (HC) | Hydrofluorocarbon (HFC) |
| Global Warming Potential (GWP) | Very low – 3 | High – 1300 |
| Energy Efficiency | More energy efficient | Less energy efficient |
| Flammability | Flammable, requires special precautions | Non-flammable, safer to handle |
| Availability | Available but might require specific sourcing | Widely available, but getting phased out in some regions |
| Environmental Impact | Lower impact, but flammable nature raises safety concerns | High GWP and ozone depletion potential leading to phase-outs |
3 Notable Advantages of Using R290 Instead of R134a
As I said earlier, you can use R290 instead of R134a. So, let’s see what advantage it can offer.
1. Energy Efficiency
R290 offers superior energy efficiency over R134a in most cooling applications. R290 is a refrigerant that can cool things better than R134a. It also makes the system use less electricity and stay cooler. This can generate substantial cost savings over years of operation.
2. Environmental Impact
A major advantage of R290 is its far lower global warming potential (GWP), at just 3 compared to 1300 for R134a. With environmental regulations phasing out HFC refrigerants like R134a, R290 provides a much more sustainable solution. However, R290 is highly flammable, requiring additional safety considerations.
3. Impact on Lives
R134a is a coolant that is used in many places. But it is bad for the air we breathe. So many countries are stopping its use. R290 is another coolant that is better for the environment.
3 risks of Using R290 Instead of R134a
Using R290 instead of R134a may cause some harm to your refrigeration system and your safety, depending on the situation. Here are some possible harms that you should be aware of:
1. Flammable
R290 is flammable and requires special safety precautions when handling and installing. You need to ensure to meet the safety requirements for flammable refrigerants in your system.
For example, proper ventilation, leak detection, and labeling. If R290 leaks or ignites, it may cause fire or explosion hazards.
2. Reduce Efficiency
R290 is not a drop-in replacement for R134a. Because it requires modifications to the system components.
For example, compressors, valves, piping, and electrical wiring. If you use R290 without changing your system, you may damage your equipment or reduce its performance and efficiency.
3. Expensive
R290 is more expensive than R134a at the moment, and it may not be widely available in your area. You may have difficulty finding a qualified refrigeration technician or engineer who can help you.
Considerations Before Using R290 Instead of R134a
Before you use R290 instead of R134a, you should consider the following aspects:
1. Safety
R290 is flammable and requires special safety precautions when handling and installing. You need to ensure that your system meets the safety requirements for flammable refrigerants. For example, proper ventilation, leak detection, and labeling. If R290 leaks or ignites, it may cause fire or explosion hazards.
2. Compatibility
R290 requires modifications to the system components. Such as compressors, valves, piping, and electrical wiring. If you use R290 without changing your system, you may damage your equipment or reduce its performance and efficiency. You need to check the local regulations and standards for using R290 in your country or region.
3. Availability
R290 may not be widely available in your area. You may have difficulty finding a qualified refrigeration technician or engineer who can help you with the conversion or maintenance of R290 systems. So, think before you swap the coolant.

FAQs
Here are some more responses to your query.
Q. Is R290 Equivalent to R134a?
You can call them equivalent as they serve similar purposes. But their chemical structures are different. And they are different.
Q. Can I mix R290 and R134a?
No, you cannot mix R290 and R134a. Mixing different refrigerants is impractical, illegal, and not economical. It can also cause damage to your system, reduce its efficiency, and change its operating pressures and temperatures.
Bottom Line
R290 and R134a are different. R290 is good for the environment and saves energy. It has a low GWP of 3. R134a has a high GWP of 1300. But R290 can catch fire easily. You need to be careful with it. R134a is safer to use. But it is bad for the environment. It is being replaced by other refrigerants.
If you want to use R290, you need to change your system. You also need to follow the safety rules. There are laws about using refrigerants. You should talk to a refrigeration expert. They can help you choose the best refrigerant for your system. They can also help you use it safely and responsibly.
