What refrigerant can I substitute for R-22?

R422D is quickly becoming a popular substitute for R22. R422D does not require changing out the oil! To learn more about R422D visit our landing page at http://stores.johnstonesupply.com/88/ and click on July's News "U" Can Use.

Which refrigerant blend is replacing R-22?

No 400-Series blend is a direct replacement for R-22. Mixing R-22 with a 400-Series blend, or mixing multiple 400-Series blends together, creates a new, untested refrigerant with unproven results. Use of alternative refrigerants voids all manufacturer warranties.

What is a refrigerant blend replacing R-22 in residential and commercial air conditioning applications that can be used in retrofit applications?

Freon™ 407C has been a popular R-22 replacement because of its properties, which include: Similar cooling capacity, energy efficiency, and pressures as R-22 in systems.

What is R-22 refrigerant being replaced with?

Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22.

HFCs and Refrigerant Blends as Replacements For R22 Refrigeration Systems

Can you still purchase R-22 refrigerant?

In 2010, the U.S. stopped the sale of newly manufactured residential air conditioning units and heat pumps that use R-22 because of its particularly harmful impact on the ozone layer when released into the air. On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22.

How much does it cost to convert R-22 to R-410A?

How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.

What class of refrigerant is R-22?

It is classified as a hydrochlorofluorocarbon (HCFC) refrigerant and has an ozone depletion potential (ODP) of 0.055 and a global warming potential (GWP) of 1810 tCO2e. All HCFCs are “Class II” ozone-depleting substances (ODS) subject to the phase out per the Montreal Protocol and U.S. Clean Air Act.

Which zeotropic refrigerant blend is used as a replacement for R-22 in air conditioning applications but operates at a higher temperature and pressure?

R-407c is a refrigerant blend of three HFC refrigerants — R-32, R-125, and R-134a. R-407c was developed in order to replace R-22, an HCFC refrigerant.

Is MO99 a direct replacement for R-22?

Yes. The mass flow rate and operating pressures of Freon™ MO99 are the closest of all the mineral oil compatible replacement products and will likely perform adequately in an existing R-22 system with a capillary tube expansion device.

What happens if you put 410A in a R-22 system?

The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur.

Is r407a a drop in replacement for R-22?

R-407A is a close match to R-22's capacities and flow rates, making it well suited as a retrofit for R-22 in supermarket and food storage applications. Additionally, R-407A is one of the more energy efficient R-22 retrofit options available for refrigeration applications.

Can I recharge R-22 myself?

As of Jan 1 2020, R22 refrigerant has been completely phased out worldwide due to its harmful effects on the ozone layer. It is no longer being produced. If you're interested in learning how to refill R22 in your air conditioner, it is important to know that this is not something a homeowner can do on their own.

Is there a refrigerant that can be mixed with R-22?

EPA regulations prohibit mixing different types of refrigerants.

Can you replace R-22 with R134a?

Also, substitutions are often not without problems. For example, when replacing R22 with R134a, there are many problems that cannot be replaced directly; the cooling power of R134a is 60% lower than that of R22, which means that the condenser of the system must work overtime to achieve the same cooling capacity.

What will replace R-22 refrigerant?

Freon™ MO99 refrigerant is a relatively affordable and eco-friendly alternative for R22 air conditioners. You can use it to revive older systems with little to no refrigerant charge, as well as systems that need replacement components. One of the best parts is that MO99 is a direct retrofit.

Which refrigerant blend replacing R-22 in residential and commercial air conditioning applications can be used in retrofit applications?

Forane® 407C is an HFC refrigerant blend that can be used to replace R-22 in new or existing positive displacement systems, including residential and commercial air conditioners and heat pumps.

Is R-22 a blend?

R-22a is a hydrocarbon refrigerant blend with primary components including flammable substances such as propane and butane. In some cases, it may also contain small amounts of other hydrocarbons or a pine-scented odorant. This refrigerant is a highly flammable, colorless gas that is heavier than air.

What is the chemical name of R-22?

R-22 – also known as Chlorodifluoromethane – is a colorless gas that is commonly used as a refrigerant. Other names for this chemical include R-22 Refrigerant, R-22 Freon, or HCFC- 22 Freon.

Is R22 Freon being phased out?

Because R-22 depletes the ozone layer, production and import was further limited in 2010. In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available. The production (not use) of R-22 is being phased out.

Are R-22 coils still available?

As of January 1, 2020, production and import of R22 refrigerant will be illegal in the United States. Of course, continued use of your air conditioner (AC) or heat pump system using R22 refrigerant is allowed.

Can I replace a R-22 compressor with a R-410A compressor?

The alterations will affect the air conditioning unit. Although they're both refrigerants, the higher efficiency of R-410A requires an upgrade to the equipment. For example, plan to replace the refrigerant tubing, the evaporator, condenser, and compressor. Other components might also need updates.

Can you use the same line set from R-22 to 410A?

To retrofit an R-22 system with R-410A system your line set must not be more than 25-50 feet in total distance. If the line set is longer than this, you will have to replace the line set with larger lines.

What is a fair price for R-22 refrigerant?

R-22 refrigerant prices range from $90 to $250 per pound. Since you'll need between 6 and 12 pounds to refill a home AC, costs can reach between $660 and $2,400 for a refill of R-22 refrigerant.
