Just have your customers sign a waiver not holding you responsible if their house explodes from an A2L refrigerant leak. These manufacturers still can’t build a coil that does not leak after all these years.
An important point was missed. The GWP effect is when there is a LEAK! not while it's in the system. When & IF it leaks when there is a fire, it will propagate the fire!!! Also, very important flammable A2L (R32 or R454B) might and could INTERNALY explode. This is true if the vacuum process (must be higher than R410A an A1 class non-flammable, non-explosive class) is not perfect (presence of moisture/oxygen) as when compressed the temperature could reach the lubricating OIL ignition temperature, and in the presence of flammable refrigerant (any A2, A2L or worse A3) the oil might ignite the flammable refrigerants! This possibility will not exist if A1 class non-flammable refrigerants are present. Neil Afram Director of Space Air Ltd. distributor of AC & Heat Pumps since 1980.
Thank you Mr. Afram for your input. You are correct. We actually offer an 8-hour class on the A2L transition that includes an ESCO certification test. Unfortunately, we can only fit so much info into these video's and I do my best to get the key points out. My intention and hope, is that our industry will start paying closer attention to this and what is happening overall. I am also trying to get folks to understand they should do the research, or get training. Our industry is changing, and will continue to change. A2L's are just the next step, more change is coming!
@@jsoriongroup Still?? why use it when there are A1 non-flammable, non-explosive and freely available?! see ASHRAE 34 table which all have to apply cause its the USER safety and nothing to do with engineers
@@neilafram663 The Kigali agreement is what is driving this low GWP transition. The EPA has set the maximum GWP value at 700 for new AC equipment manufacturing. Pretty much all of the A1's your referring too have a GWP above the 700 allowed value. This means that the equipment will (actually has already begun) be designed and contain the new low GWP refrigerants that are slightly more flammable than the A1's we've been using. You can absolutely continue to use A1's as long as they continue to be available. However, soon you will NOT be able to purchase new equipment that contains an A1 refrigerant. A2L's will be our future. I highly recommend everyone become familiar and seek training. Go to an appliance store and look at the refrigerants used in household refrigerators. You will see lot's of R-290, which is straight propane. This is our current reality. Thanks for reaching.
What a CLIFFHANGER! When do we get episode 2??
Nice work guys!
Stay tuned for next week's training center email!
Friday!

His beard looks awesome 👏
Thank You! I started growing it as a tribute to a great friend and fellow HVAC Tech who lost his battle with cancer.
