What can you use instead of R22?

A few popular R22 alternatives are R410A, R134A, R407C, R407A, MO99, and RS-44b. This type of refrigerant is safe for the environment, affordable, and easy to store, use, and transport.

What can be used in place of R22?

R410A as substitute for R22. In addition to R407C, the near-azeotropic mixture listed by ASHRAE as R410A is available and widely used for medium-sized capacities in air conditioning and heat pump applications.

Is there a drop-in replacement for R22?

Description. RS-44b (R453a) is the newest R22 drop-in replacement refrigerant in the U.S. market. RS-44b has been sold worldwide for the past 5 years, branded as RS-70 outside the US. It is the closest replacement to R22 that operates with very similar discharge pressure, cooling capacity and flow rate as R22.

What is the closest refrigerant to R22?

Freon MO99 is the closest capacity match to R-22 compared with most other no-oil change refrigerants.

Can I use R410A instead of R22?

No, you cannot. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system.

Converting a R22 system to R407c

Can I use R32 instead of R22?

Relatively, R32 has very low GWP compared to R22, and therefore leading R32 to be a potential substitute for R22.

What happens if you use the wrong refrigerant?

You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you're not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.

Can you use 407C in place of R22?

The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants.

Does Home Depot sell R22 refrigerant?

Wilmar - The Home Depot Pro Multifamily - Maintenance, Repair and Operation Supplies - R-22 Phaseout. Only EPA-certified technicians can purchase refrigerants. You must provide proof of an active certification prior to ordering any refrigerant cylinders.

Can I use 134a in a R22 system?

Using R134a in Systems Designed for R22

R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger. A system circulating R134a needs a dryer, because of the propensity of the refrigerant to absorb water.

Can you use 404a in place of R22?

R404A and R507A as substitutes for R22 and R502. These blends are chlorine free substitutes (ODP = 0) for R22 as well as for R502 in medium and low temperature ranges.

Can I still buy R22 refrigerant?

R22 refrigerant is illegal to import and manufacturer in the U.S. But it's not illegal for anyone to buy R22 freon. And it's not illegal to sell it IF you have a license. As long as the stocks last, you will be able to continue purchasing R22 from specialized dealers and form your air conditioning company.

How much does R22 freon cost per pound?

Your HVAC specialist can snag R-22 freon for $20 to $50 per pound wholesale. However, when you call on a repair team to replace it, expect your bill to run from $90 to $150 per pound.

Why is R22 so expensive?

R-22 refrigerant is so expensive because there's such a limited supply of it left. You see, R-22 is an “ozone-depleting substance” and is extremely harmful to the environment. Because it's so dangerous, countries around the world have been slowly phasing out this refrigerant since 2010.

IS 407C more efficient than R22?

The R407C compressor shows exergy efficiency higher than the R22 one due to its better isoentropic efficiency. R22 condenser exergy efficiency is higher than the efficiency ofR407C. Exergy efficiency of the R22 expansion valve is much higher than exergy efficiency of the R407C expansion valve.

Is R407C still legal?

There are currently no restrictions on equipment or use of the following refrigerants: R134A, R407C, R410A, and R417A.

Are 407C pressures compared to R22?

Devotta et al. (10) informed that R407C had higher pressures than R22 with discharge pressure of R22 being at 2193 kPa for the lower outdoor conditions and 2784 kPa for the higher outdoor conditions. For all operating conditions, the discharge pressure of R-407C is varied in the range 11-13% higher than R22.

What happens if you put R-410A in a R22 system?

If you put R410-A into an R-22 system, the parts will rupture due to the increased force. You can convert your current system to one that runs on R-410A, but the cost will be high.

Can I use car refrigerant in my home AC?

No, they are not interchangable. The gauges are marked with specific temperatures and pressures that correspond to the refrigerant you're using. You can't check the charge on a home unit with an auto gauge set, and vice versa.

Can I use the same gauges for R22 and R-410A?

R-22 and R-410A, while intended for the same type of appli- cations, are indeed very different refrigerants. Therefore, they cannot be mixed, and the equipment they are used in will be different.

Which gas is best for air conditioner?

The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.

Which gas is better R32 or R22?

However, they are better compared to R22. The R32 refrigerant has three times lower GWP and is also more energy-efficient as compared to R410A. Most well-established companies such as Mitsubishi, Hitachi, Fujitsu, Panasonic and Toshiba are opting to use the R32 refrigerants in their AC conditioners.

How much does R-22 cost now?

R22 Freon costs $90 to $150 per pound installed or $13 to $21 per pound wholesale. R22 refrigerant is the old standard for residential air conditioners, which is now banned and no longer produced.

How many pounds of Freon does a 3 ton air conditioner hold?

The 3-ton AC or Heat Pump with a 35 foot lineset will need a total of about 12 pounds of refrigerant.

Is 2 pounds of Freon a lot?

Amount of Freon in Units

As for how much Freon is in each unit that could be lost due to damage, the general rule of thumb is 2 1/2 pounds of refrigerant per ton of cooling. The tonnage of an A/C unit determines its size and the amount of space it can cool, with larger tonnage units providing greater cooling abilities.
