Maybe this can answer your question in the meantime: Today, it is 15 degrees out side, and the thermostat is on 70 degrees. We don't have the heat strips hooked up at the thermostat. If the HP goes into defrost mode it will shut the indoor blower off. The blower will not come on until it gets to a certain temperature. This eliminate a blast of cold air from blowing in the home
They say the pressures from 410a to 454b are only slightly different, are they slightly higher or lower? Also are rtu's going to have the same requirements of new refrigerant?
We believe the operating pressure for R454B is slightly lower. The R454B will be in all NEW equipment including new rooftop units. RTU's that use older refrigerants can still use old refrigerant!
@blueridgeheatingair24 ok thanks slightly lower is a good thing because some of these evap coils can't handle the 410a pressure, I'm getting mixed info about rtu's from some local supply houses saying that 410 units will still be sold for many more years unlike resi units just finishing out their stock pile throughout 2025
More than likely, if you're looking to purchase before the end of the year, you'll be considering an R410A ('Freon') unit. Opting for an R410A system could save you money in the long run, as it’s a proven, reliable option with established technology. Plus, you won’t have to worry about potential hiccups that may arise with the newer R454B equipment, which is still in its early stages of use. However, if you'd prefer to stay ahead of the refrigerant mandate and prioritize environmental initiatives, R454B units are a great choice. Just keep in mind that they may come with slightly higher upfront and maintenance costs as the technology and industry adjust to this change. Ultimately, the best option depends on your unique home and situation. I would be more inclined to purchase an R410A unit personally due to the fact it will probably end up saving you money over the next few years. We recommend speaking with local HVAC professionals to discuss what brands and models suit your needs best. Trusted brands like Trane, Goodman, York, and Armstrong Air are solid choices no matter which refrigerant you decide on.
I had the carrier 25vna60a003 It leaked freon and now the dealer wants to disconect the high effenciey side. how does that effect the 24 sear efficency.
Hey without knowing more details about your situation, perhaps this response will somewhat help: To Disconnect the high efficiency side of a system is to run at low speed all the time. I don't know the system break down but it Probably will run at 60%. And if it is a refrigerant problem, it will eventually leak out and run on emergency heat causing the power bills to rise.
I have heard mixed reviews about the last change in refrigerant. Generally you don't want to hear anything bad but it seems like there will be some inevitable kinks. Some people have made the analogy of brand new car series which sometimes have mass issues that need to be fixed at the dealership. This chat exchange might shed some light on your question: hvac-talk.com/vbb/threads/2272707-R-410-to-R-454b-transition-(problems-)
Luckily a lot of the new technology is very similar to the tech that handles the old refrigerant. There maybe a learning curve but we are sure they can handle potential initial kinks quicky.

@@blueridgeheatingair24 Propane heat pumps are about 100 years old .. how much time to regulators need? They hold about a tea pot of propane.. my bbq has 20. In an air to water system no propane enters the house. It is sealed. This smacks of either incompetence or corruption.

Awesome!
Are they calculating in the defrost cycle where you going to cooling mode or is that without the defrost cycle?
Hey Dave, thanks for the question! Are you talking about the refrigerant change in general or the part where we were talking about Heat Pumps?

Will you be able to install the flammable refrigerant ontop of a 80 percent furnaces
Yes sir!

Were there issues with the transition to #R410A years ago?

10 years ago 410a was the answer to r22
They called 410a Puron and now they say it’s 3 times worse for the environment than 22. Money grab they don’t care about the environment.
The consumer gets screwed again !
I don’t think all manufacturers are using 454b.
They are already planning on phasing out these new refrigerants in 8 -9 years.
Good sales meeting for your mini spit systems. I hope they’re Mitsubishis .
Will technicians be ready to service all aspects of the new R454 equipment?

the instructor did not know what AHRI stood for? thats scary.
Conceptual understanding without lexical recall :)
I really wish they would leave our trade alone for a while
Haha that would be the dream, right? I fear we will go through another change in about 10-15 years
I want R290 A/W monoblocks for cold regions. Pathetic how Europe and Asia are so far ahead of us.
It seems like they are BETA testers!

What kinda questions are these? Are these guys even in the industry?
My thoughts exactly, "how would we know what type of gas is in our existing system?" Like obviously there will be a label on the unit.

This is gonna be such a shit show with 454b!
Haha! We will attack this change with enthusiasm and optimism!
Equipment training or training retired homeowner to try and bully me ? Not repping thatv
