5 HVAC Refrigerant ISSUES Homeowners NEED To Know!

I miss R22. Old heat pump lasted 30 yrs with almost no professional service.

R22 ❤️

Maybe if these bureaucrats were working in an office instead of trying to do their job while in their recliner watching I love Lucy reruns they would have thought these things through.

Every change, somebody makes money. More sale scare. Not afraid of change. Follow the money.

Hard to argue

I have a friend who converted R12 to propane on a vehicle, and is very comfortable.

Refrigerants have to change because patents run out. All just $

[@NewHVACGuide]

Does R32 appeal to you being that it's not a patented refrigerant like 455b?

@@NewHVACGuide Daikin owns the patent since 2011 on R32.

[@NewHVACGuide]

That patent was released a few years ago.

​​@@NewHVACGuide Advantages between R32 and R454B R454B is 68.9% R32 and 31.1% R1234yf by weight. GWP 466 R32 is 100% R32. GWP 675 Advantages to to R454B: 1. R454B the properties pressures and mass flow rate are are similar to R410A. Manufacturers didn't need to spend as much money retooling their factories because it's properties are similar to R410A. Advantages to R32 1. R32 uses a compressor that is about 1/3 the size of R454B or R410A 2. R32 uses about 1/3 the charge of R454B or R410A. Manufacturers like to make the claim that R454B is better for the environment with a lower GWP but this is about equil because R32 systems use about 1/3 the amount if refrigerant. Over the long term R32 saves production and environmental costs because compressors are smaller containing about 1/3 the metal of an R454B system. Similar to the transition from R404A to R290 in refrigeration. 3. R454B contains R1234yf, once in the atmosphere it breaks down into trifluoroacetic acid (TFA), which is considered a PFAS (per- and polyfluoroalkyl substances) Europe is starting the process of banning all PFAS due to their health problems. 4. Price R32 is not only cheaper per pound than R454B but it only takes about 1/3 the amount of R32 in the system making future repairs much cheaper. R32 is the clear winner here it is a shame that the US manufacturers decided to look at short term profits over long term gains. In the future we will probably be moving towards mono-block chillers with R290 as the refrigerant kept outside of the building.
