Yes, it is possible to convert an R-22 system to 410A, although it is not without its complications. Conversion from one refrigerant to another requires several changes in the air conditioning system, including adding or replacing certain components and/or parts.
The most important factor when performing the conversion from R-22 to 410A is the lubrication type. During the conversion, the lubricant inside the system must be changed from mineral oil to a polyolester or polyalkylene glycol oil.
It is important to caution that incompatibility between the two types of oils can cause serious damage to the system.
In addition, the condenser and evaporator coils need to be replaced with 410A friendly units. The existing line set and filter drier should also be replaced, as sub-cooler and/or accumulator changes may also need to be implemented.
The system will also require proper charging to ensure the optimal performance of the newly converted system.
Ultimately, despite the efforts and expense involved, it is still possible to convert an R-22 system to 410A. It is advisable, however, to consult a professional to ensure that such a conversion is done in a safe and proper manner.

How much does it cost to convert R-22 to R-410A?
The cost of converting an existing R-22 system to R-410A depends on a number of factors, including the size and complexity of the system, the accessibility of the equipment, the installation costs, and availability of parts and materials.
To completely convert an R-22 system, expect to pay between $2,500 and $5,000 in materials and labor. This cost can vary depending on the specific components needed for the system, such as coils, fan blades, condensers, valves, and other parts.
The cost can also vary from contractor to contractor, as different contractors may have different labor rates and access to different materials. Additionally, if the existing system is aging and requires additional services such as duct sealing, insulation, and air filtration, these additional services can add to the overall cost of the project.
Can a R-22 unit be converted?
Yes, a R-22 unit can be converted. The conversion process requires changing the components in your current cooling system to one that is compatible with a refrigerant other than R-22. This involves replacing your evaporator coil, outdoor condenser unit, and line-set and complete flushing of the air conditioning system.
Additionally, you may need to replace and replace the thermostat – depending on the type you have. After this renovation process is complete, the air conditioning unit should be recharged with the appropriate replacement refrigerant that is compatible with your unit.
To perform a safe and successful conversion, it is important to obtain professional assistance in order to ensure that the system is correctly changed and charged.
What is the replacement for R-22?
The replacement for R-22 refrigerant is R-410A, also known as Puron. R-410A was designed to replace R-22 as the refrigerant of choice for use in residential and light commercial air conditioning and heat pump systems.
R-410A is a blended refrigerant comprised primarily of hydrofluorocarbons (HFCs) and refined hydrocarbons (HCs). While R-410A is not ozone-depleting, it does contribute to global warming due to its high GWP (Global Warming Potential).
R-410A operates at higher pressures than R-22, and the use of R-410A requires the use of cabinets, condensers and other components that are compatible with R-410A. To ensure proper replacement of R-22 with R-410A, the system should be serviced with certified technicians as per ASHRAE standards.
What freon can you replace R-22 with?
R-22 refrigerant can be replaced with R-410A (Puron) or R-407C (AZ-20) refrigerants. Both of these refrigerants are a zeotropic blend of two refrigerants; R-32 and R-125 for R-410A, and R-32 and R-134a for R-407C.
The biggest advantage of using these refrigerants is that they are not a single component of the ozone-depleting HCFCs like R-22, making them a more environmentally friendly option. Additionally, these “drop-in” refrigerants are designed for use in systems that originally used R-22 to work without a significant level of retrofitting.
However, it would be recommended to consult with a certified HVAC technician to be sure.
It is important to note that the use of any refrigerant, including the newer replacements, are subject to the local laws governing the handling and use of refrigerants in your area. In addition, changing the refrigerant often requires different lubricants and sometimes more space in the condenser coils to account for the higher volumes of these newer refrigerants.
Can R22 be recovered and reused?
Yes, R22 can be recovered and reused. This is done by a process called refrigerant recovery. Refrigerant recovery is a process in which the R22 is condensed in a machine and removed from the system it is in.
The recovered refrigerant is then stored in a tightly sealed container, typically a cylinder or drum, away from any source of heat. Recovering the R22 not only allows you to reuse it, it can also help protect the environment from the R22 being released into the atmosphere, as it is a hydrofluorocarbon (HFC) that is known to contribute to ozone depletion when released.
Can you put 407c in a R22 unit?
No, you cannot put 407c in an R22 unit. 407c is an environmentally friendly, non-ozone depleting replacement for R22, so the two are not compatible. Additionally, R22 is a single-component refrigerant, while 407c is a mixture of four components.
Not only would the different chemistry of 407c potentially cause damage to the system but the use of the wrong refrigerant could also void the equipment warranty. For these reasons, it is imperative that only the recommended refrigerant be used in a unit, and therefore, 407c should not be used in an R22 system.
Can you replace R22 with propane?
No, R22 and propane are two different refrigerants and are not compatible as substitutes for each other. R22 (chlorodifluoromethane) is an HFC and a potent greenhouse gas, while propane (R290) is an HC and considered a safe refrigerant with a negligible contribution to global warming.
For this reason, R22 is being phased out and can no longer be used in new equipment. Propane cannot be used to replace R22 in equipment that was designed to use R22 because the two refrigerants have different chemical compositions, and will not work together in the same system.
If a system needs to be serviced or upgraded to utilize a different refrigerant, a qualified technician must confirm the compatibility of the system components, then retrofit or replace components as necessary for the new refrigerant.
Additionally, the new refrigerant must comply with all federal, provincial, and local regulations.
What happens if you mix R22 with 407C?
If you mix refrigerants R22 and 407C, it can be very dangerous and should never be done. The chemical makeup of the two refrigerants is completely different, and mixing them can cause irreversible and hazardous chemical reactions, creating a very explosive mixture.
Additionally, due to the difference in chemical composition, the two refrigerants will not have the same physical properties, and the resulting mixture will be unpredictable. It is possible that the mixture won’t function as expected when used in a refrigeration system, leading to poor cooling efficiency and a significant decrease in performance.
This could cause further damage to the system over time. Therefore, it is not recommended to mix R22 and 407C at any time.
What happens when R22 is phased out?
When R22 (also known as Freon) is phased out, it means that the greenhouse gas will no longer be used as a coolant or refrigerant in refrigeration and air conditioning applications. This phase-out was mandated by the 1990 Clean Air Act Amendments, with the full phase-out from production and import slated for 2020.
The main issue with R22 is its high ozone depletion potential. Phasing it out of use and production will help protect the ozone layer and limit climate change. There is both a short-term and a long-term impact of this switchover.
In the short term, it means that fewer R22 units can be put in service. Organizations will, therefore, need to switch to alternative refrigerants – such as R410A – that have much lower ozone-depleting potential and global warming potential (GWP) values.
In the long term, evidence points to a continued switchover to alternative refrigerants. Many countries have already implemented or committed to phase-out dates earlier than 2020, so alternative refrigerants are already being used.
Organizations should also consider energy efficiency when selecting refrigerants. As energy-efficient alternatives become more readily available, businesses can lower their carbon footprint and save money on energy costs.
The phase-out of R22 is an important step to protect the environment and limit climate change. It also serves as an opportunity for organizations to reassess their refrigeration and air conditioning systems and investigate alternative cooling options.
How much does it cost to add 410A refrigerant?
The cost of adding 410A refrigerant can vary depending on the type and size of unit, as well as the local refrigerant supplier. Generally, purchasing a pound of 410A refrigerant can cost around $28-$40.
When dealing with large quantities, the cost will be determined by the supplier. Additionally, the cost to have a qualified technician install the refrigerant can range anywhere from $50 to $100 an hour depending on labor costs in the area.
How much does a 410A cost per pound installed?
The cost of 410A per pound installed will vary depending on a number of factors, including the location of the installation and the complexity of the project. On average, 410A can cost between $4-$6 per pound installed.
However, prices may be higher or lower depending on the specific provider in the area. When planning a project involving 410A, it is important to get price quotes from several providers to ensure that you are getting the best rate possible.
It is also important to keep in mind that installation can add additional costs to the overall project. Therefore, it is important to factor in installation costs when estimating the overall cost of the project.
Can you buy 410A refrigerant without a license?
No, 410A refrigerant cannot be purchased without a license. For starters, the Environmental Protection Agency requires that anyone who purchases, transports, services, or uses HCFC-22, commonly known as R-22 or Freon, or HCFC-410A, require a Section 608 certification.
Section 608 of the Clean Air Act is what regulates refrigerants and the people who handle them. Technicians must obtain a certification from the EPA, inform the EPA they are handling, purchasing, and/or transporting refrigerant, and, in some cases, document the amounts of refrigerant they buy and use.
Therefore, it is necessary to have the right license in order to have access to 410A refrigerant.
Why is 410A Freon so expensive?
Freon 410A (R-410A) is an HFC refrigerant and has been in use since the early 2000s. It is considered one of the most efficient and environmentally friendly refrigerants, making it a popular choice for air conditioning systems and other cooling applications.
Unfortunately, its efficiency and environmental friendliness come at a cost. Since it is a relatively new refrigerant, the cost of Freon* 410A is higher than that of traditional HCFC or HFC refrigerants.
In addition, Freon 410A is classified as an ‘electricity-intensive’ cooling agent, meaning that it uses more electricity than many other refrigerants, therefore resulting in an increase in energy costs overall for any systems utilizing it.
The high cost of Freon 410A is further driven up by the taxes and duties applied to the purchase of equipment or systems containing this kind of refrigerant. In addition, authorities and governments have regulations regarding the handling and installation requirements for systems utilizing R-410A, which can add additional costs to the purchase.
Finally, the price is also linked to the demand and a lack of suppliers in some areas, as many parts of the world still use older refrigerants due to their lower cost and lack of awareness of the environmental benefits of Freon 410A.
What can I use instead of 410A?
An increasingly popular alternative to 410A is R-410A, otherwise known as Puron. R-410A is an HFC (hydrofluorocarbon) refrigerant that contains no chlorine and, unlike R-22 (Freon), does not harm the environment.
R-410A uses a blend of two different refrigerants, which improves its thermodynamic properties, so it works better in a variety of temperatures, including extreme cold and hot weathers. R-410A also has a much higher pressure and requires condensing units and evaporator coils specifically made for the use of R-410A, which need to meet certain manufacturer and safety standards.
The increased pressure is actually an advantage because, even at extreme temperatures, it can maintain the same pressure—allowing the unit to operate more efficiently and cost-effectively, while also consuming less energy.
Additionally, R-410A is more energy-efficient, cost-effective, and doesn’t require any oil blending.
