It is not acceptable to substitute R410A, which operates at different pressure levels than that of an R22, without major changes and engineering analysis. And, safe disposal of refrigerants regulated by the EPA is mandatory.
R-22 uses simple mineral oil, non-toxic, safe, stable, etc. while R-410a uses a somewhat exotic Poly o Ester (POE) oil typically found in jet turbine engines. The refrigerant used MUST match the oil present in the system, which is one reason why you can't replace the R-22 with R410a in a system.
Freon MO99 (R-438A) is the Preferred Alternative for Retrofitting. Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22.
Since R410A refrigerant is charged under higher pressure, charging an R22 system with it will increase the force within the coolant lines. The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either.
The operational pressure of the refrigerant R410A becomes higher compared to R22. In the worst case, a lack of compressive strength may lead to piping explosion.
So what the manufacturer recommends, the best option, is if you're going to go from an R22 unit to an R410 unit, that you should have your line set replaced at the same time.
If you're going to convert from R22 to R410A refrigerant, the best thing to do would be to flush the lines you have, and put in units, an air handler and condenser that is meant to use R410A.
You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force.
In fact, R410A can cool a room slightly faster with less energy. Efficient performance is a significant benefit of R410A. However, it works the same way as R22 in absorbing heat to provide cooling. But R410A doesn't make a room any colder than its predecessor.
Tube-side materials in R-410A coils need to be thicker due to the higher operating pressures associated with R-410A relative to R-22. We're not arguing that there's not a difference in operating pressure between the two. There is – roughly 130 PSI for R-410A evaporators compared to about 70 for R-22.
R410A is the most common, but others include R134a, R407C and R407A. These refrigerants cool interior spaces just as effectively as R22 with no ozone depleting characteristics and relatively low Global Warming Potential (GWP).
Understanding the Current HVAC Refrigerant Guidelines
Most HVAC brands have started to swap out their older AC and heat pump units over the year, preparing for the 2025 deadline, when they will have to completely stop the production of systems with R-410A.
Final answer: Of the provided options, R-407C is the approved 'drop-in' replacement for R-22, commonly used in air conditioning systems. However, despite this 'drop-in' status, it may still require some changes to be implemented in the system.
When you replace an air conditioner or heat pump and upgrade from R-22 to R-410A, the ideal solution is to replace your refrigerant lines. This is because the mineral oil used in R-22 systems is not compatible with the new R-410A refrigerant and oil.
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.
Regulatory Changes: As the phase-out continues to restrict production levels and importation, the R-410A price will likely increase. Manufacturing Costs: Fluctuations in the cost of raw materials and manufacturing can also influence the price of refrigerants.
R410A or Puron
This eco-friendly refrigerant gives you a much higher cooling efficiency with very little power consumption.
The chief drawback of R-410A is its Global Warming Potential. While the Montreal Protocol sought to eliminate substances with the potential to deplete the ozone layer, most refrigerants developed in response to the treaty are not altogether environmentally unharmful.
What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant R-454B due to its excellent performance for ducted systems and zero ozone depletion potential. For mini-splits, we selected R-32, designed to optimize efficiency and reliability in ductless systems.
Since the pressure generated by R410a refrigerant is 1.6 times that of R22 refrigerant, it requires that the copper tube has a large density, strong compressive resistance, high copper tube cleanliness and uniform copper tube wall thickness, so the air conditioning system of R410a refrigerant must use special R410a ...
Beyond being the more Earth-friendly option, R410a also performs better than R22 refrigerant. R410a absorbs and releases more heat so that your air conditioning compressor runs cooler and more efficiently.
The answer is an undeniable and indisputable yes. Though you may hear several opinions to the contrary, we know from experience that it will cool equally as well as the old unit. When tuned properly, it will produce at least as cold of air as the R22 counter part being replaced.
An R-22 Refrigerant Replacement for Direct Expansion Refrigeration. Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22.
The air-conditioning copper pipe is mainly connected to the indoor unit and the outdoor unit. The refrigerant flowing inside is the refrigerant (Freon). If the copper pipe line is too long, the refrigerant will flow at a slower speed, resulting in no refrigerant in the air-conditioning compressor.
