Some data to ponder:

R-22 - 1800 GWP

R-410 - 2000 GWP
------------------------------ flammability threshold
R-32 - 675 GWP

R-454 - 457 GWP

R-290 - 3 GWP (propane)

R-600 - 3 GWP (butane)

So, if the goal is to save the planet/atmosphere/all life as we know it, why are we now switching to an expensive chemical company produced refrigerant with a much higher Global Warning Potential rather rather than one of the two inexpensive oil refinery produced refrigerant with essentially zero Global Warming Potential? Any ideas?

Almost every vehicle on the road today is carrying gallons of highly flammable and potentially explosive fuel. Every day regular untrained people cheerfully slosh their fuel tank full with their children sitting right on top of it. And nobody so much as raises an eyebrow - but highly trained and skilled professional HVAC people apparently cannot be trusted with R-290 or R-600.

Let me predict right here that inside of 20 years we will all be getting rid of the 'by then horrible' R-32 and R-454 and . . . . installing all new equipment for it. Just like we did for R-12 and R-22 equipment. Again. <g>

And who will pay for all of it? The hapless Consumer.

The gov. does not want us to use fossil fuels anymore. Crude and Natural gas processing is a big no no.:grin2:

Maybe 20 years from now Thermoelectric cooling will replace refrigerants.

Maybe 20 years from now Thermoelectric cooling will replace refrigerants.

And electricity will generate itself.

And the rest of the HVAC people can't be trusted with it either. There are a lot of YouTube videos of some of those not so highly trained and propane.

world wide? most of the world uses ISO 5149 or EN378, these codes not only allow the use of A2L and A3 in residential and commercial applications but also the use of B2L, the codes are also a decade old now.

It's not the highly trained and skilled professional HVAC people that are the problem. It's the hacks, butchers, and scumbags who make up the other half of the people in this business. You know, the ones who do service but don't own a meter. The ones who install units without ever cracking the manuals. The ones you see on the TV every time the news has one of those "stings" where they catch bottom feeders ripping people off.

I know licensed contractors that I wouldn't trust with a 6-in-1 screwdriver, much less a jug of flammable refrigerant. Remember all the idiots buying R22A and topping units off with it? These are the people that give HVAC a bad reputation.

BTW the NFPA says that there are an average of 5,000 gas station fires every year, which result in an average of 2 deaths, 48 injuries, and $20 million in property damage per year.

I'm a little confused. Is the tech saying that when your dual capacitor went bad the motor was overheating? Or is he saying it overheated while he was working on it? Did he measure the motor amps while it was running? If the amp draw is normal and the motor is running and not making noise I'd say leave it alone.

How old is your current system? 12? If its running well and not leaking refrigerant then you should still be able to get plenty of use out of it. Replacing it because of the 410A phase out is pointless anyway since no one is selling units that use the new refrigerants yet. You'll just end up with another R410A unit. As for the phase out, it won't happen for years and R410A will be readily available for years to come.

I think you need to find a new service company.

I used to tell my technicians if you are looking for answers as to “why” simply follow the dollar &#55357;&#56501;. This will answer your question 100% of the time. This latest refrigerant merry go around is no different.
