Which of the following is true of chlorofluorocarbons? Answers: The CFC molecules react with ultraviolet light to release chlorine which then destroys ozone. The CFC molecules react with ultraviolet light to release fluorine which then destroys ozone.

If you add R-134a to an R-22 system, you will blow the compressor. R-134a works up to 450 psi (typical hot gas condensing pressure). R-22 systems are typically about 300 psi maximum. If you add R-22 to an R-134a system, you will not get close to the rated cooling capacity of the A/C system.

Mixing R22 with R407C or any other refrigerant. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined. If your system is running on R22 most likely is using mineral oil to lubricate the compressor.

Understand this: The mineral oil in a compressor has a vapor pressure. If that’s so, then what R22 there is in the system can never evaporate under the higher suction pressure of R410a. It will just flood back to reduce the compressor life and will greatly reduce the system capacity.

The cost to convert a central air conditioner from R-22 to R-410A can range anywhere from $2,000 to over $4,500 in the New Jersey area. The bottom line? If your AC unit is 8+ years old, it’s usually not worth the cost to convert and you should just replace the entire R-22 unit with an R-410A unit.

R22 uses 1/4″ Schrader access valves. R410A uses 5/16″ access valves. The refrigerant type is usually on the compressor label or nameplate. Additionally the oil type is usually noted.

410A operates at a much higher pressure than R-22, between fifty to sixty percent higher. To accommodate this increased pressure the compressors and other components are built to withstand the greater stress. R-22 oil will not flow through a 410A system and will most likely end up accumulating in your evaporator.

The lower critical temperature of R410A versus that of R22 (70.1 °C (158.1 °F) vs. 96.2 °C (205.1 °F)) indicates that degradation of performance at high ambient temperature should be greater for R410A than R22. The R22 system cooling capacity decreased by 14 % at an outdoor temperature of 51.7 °C (125.0 °F).

No. You can’t do that. It probably wouldn’t work. Even though you put a compressor in there that’s R410A, the rest of condenser probably isn’t tested and rated for operating at R410A pressures because R410A has to operate at a higher pressure.

While an R-410A system still uses harsh chemicals, it is not as damaging to the environment. It does not harm the ozone layer or cause cancer like R-22 refrigerant does, and will help your system work efficiently with less environmental impact. It is still not perfect, but it’s the best the industry has for now.

Improved efficiency: R410A is able to absorb and release heat better than R22, making it more energy efficient. Plus, because it’s more fluid in temperature changing abilities, it does a better job heating or cooling your house quickly.

The leading replacement for R-410A refrigerant is a pure, single component refrigerant called R-32, which has one-third the global warming potential of R‑410A. Some products with this next generation refrigerant have already been introduced in the United States.

On January 1, 2010, the Environmental Protection Agency (EPA) implemented a ban on the production and import of R22, except for continuing servicing needs of existing equipment. The EPA also banned the manufacture and installation of new R22 AC or heat pump systems.

All new home AC units in North America uses R410a, also known as Puron. But this refrigerant will consequently be phased out. This is due to a continued focus on reducing compounds known to have an effect on the environment. To find out the “why” that causes AC restrictions, it’s useful to put it into perspective.

R410a is actually a blend of two different refrigerants, one of which is called R125. There’s currently a world shortage of R125 because there aren’t enough plants to produce it. Without enough R125, producers can’t make enough R410a to keep up with the increasing demand.

Genetron® AZ-20® (an azeotropic mixture of HFC-32/HFC-125, assigned R-410A by ASHRAE), has been developed by Honeywell to serve as a long-term, non-ozone-depleting replace- ment for HCFC-22 in a variety of new-equipment applications. Because it behaves like an azeotrope, Genetron AZ-20 is easy to service in the field.

You are required to have an EPA Section 608 Type II or Universal certification license to handle R-410A but no license is legally necessary for purchase.

ANYONE can purchase and handle 410a. NO certification or license needed.
