Do you have a choice of replacement for the R-22 Refrigerant in your HVAC system?
Yes…and here is a chart of alternatives:
First, I am not an HVAC expert and I didn’t sleep at a Holiday Inn last night, but are we being duped into replacing out HVAC systems in our homes instead of simply replacing the existing R-22 in our systems?
Second, aren’t HVAC systems supposed to be “closed systems”? This means that there “SHOULD NOT BE ANY LEAKS” in the refrigerant lines….so why are there…
LEAKS IN HVAC REFRIGERANT lines? They are normally copper lines which really shouldn’t leak…
I was told by an HVAC technician years ago that HVAC systems use different metals to connect the circulation system and over time, those metals interact to develop leaks. I can’t verify that statement, but several older systems, designed as “closed systems”, mysteriously develop leaks in copper tubing or at connection points within the system.
Watch this video: What is RS-44b ( R453a ) Refrigerant and Should You Use It?
RS-44b Refrigerant is an R22 Replacement.
Also, After many years of testing and investigation, R407C is recognized as a suitable alternative refrigerant for R22 in medium and high temperature applications such as residential and light commercial air conditioning.
RS-44b Refrigerant: RS-44b is a non-flammable HFC blend. It is compatible with both traditional mineral and synthetic lubricants so that a retrofit to a different refrigerant oil is not required. The small amount of hydrocarbons in RS-44b improve the oil return to the compressor to extend the life of the compressor. (Source: rs-44b-refrigerant-r22-replacement)
407C Refrigerant: R-407c is a mixture of hydrofluorocarbons used as a refrigerant. It is a zeotropic blend of difluoromethane, pentafluoroethane, and 1,1,1,2-tetrafluoroethane. Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. R-407c cylinders are colored burnt orange. (Source: Wikipedia)
R422D, Another R22 Replacement.
So, are there alternatives to HVAC companies “scaring you” into selecting new HVAC systems and changing out your older system to a newer one? It appears so, but if you want a more efficient HVAC system in the future, you may need to replace your current system to achieve those benefits.
