What is r22 and why is it phasing out?
R22 was a commonly used refrigerant that is being phased out because of its harmful impact on the ozone layer. If your HVAC system uses R22, don’t panic -- you can still use and maintain your system as normal. But, when it’s time for your system to be replaced, you’ll need to upgrade to a more environmentally-friendly alternative.
How much does R22 refrigerant cost to replace the contractor?
The cost of R-22 per pound is $20 to $50 when purchased wholesale by your HVAC specialist. However, when you call on a repair team to replace R-22, expect your bill to run from $90 to $150 per pound for installation. It's important to note that a high-functioning HVAC system only requires a refill if something is wrong.
What can I 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 is the difference between R22 and R407C?
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.
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.
Can you replace R22 with another refrigerant?
But even if it's possible to retrofit your unit to accommodate an R22 Freon substitute like R410a (or another acceptable alternative refrigerant), it may not make sense to retrofit a system that is already ten or more years old. That's because the retrofit requires a nearly complete overhaul of the unit.

WHAT IS 407C refrigerant used for?
Product summary. R-407C is a non-azeotropic mixed refrigerant composed of the three ingredients R-32, R-125, and R-134a, and was developed as a substitute refrigerant for R-22, used in applications such as air conditioning equipment and chiller equipment for medium temperature ranges.
Do you charge 407C as a liquid or vapor?
liquidR-407C should always be charged as a liquid. Due to its zeotropic nature, it will fractionate if charged as a vapor, causing poor system performance — and, possibly, system failure. Additionally, the refrigerant supply in the cylinder may become out of spec if discharged as a vapor.
