Adams: About 85% of HVAC systems are replaced during emergencies
“It's almost all air conditioners and furnaces are replaced on an emergency basis. They go out when it's hot or it's cold. So it's about 85% Is the number for that?”
Adams: Heat pumps cost just $300 to $600 more than standard ACs
“And so a heat pump is only marginally more expensive than an air conditioner with, you know, 300 to 600 bucks for the same model if you're looking at the same piece of equipment.”
Rivest: Air conditioning emissions are 60% electricity, 35% refrigerants, 5% embodied
“There are three major components. One is having to do with the manufacturing and transport of those, and sort of the embodied emissions. And that's about five percent of the emissions that we see coming from air conditioners. There's another 35% that comes fro…”
Rivest: Commercial ACs overcool air to 50°F before reheating to 70°F
“So what air conditioners do today in a nice commercial building in the U.S. Is they cool air from 90 degrees down to 50 degrees Fahrenheit to get it really, really dry, and then they heat it back up to 70 degrees to make it a comfortable temperature.”
Rivest: Humidity management uses over half of AC electricity on average
“But it turns out that humidity is using on average a little bit more than half of the electricity of our air conditioner.”
Rivest: Air conditioning is the leading cause of electrical grid blackouts
“I don't know if ice solves the electricity consumption and CO two emissions part of the problem, but it certainly solves a really important problem about air conditioning, which is that air conditioners are the number one cause of blackouts on the electrical g…”
Rivest: Heat pump mandates accelerate the retirement of inefficient air conditioners
“What I think is really interesting about all these heat pumps coming online for heating purposes to replace natural gas is that this disrupts the sales cycle of air conditioners as well as a side benefit. So now you have air conditioners, which would last for …”
Rivest: Air conditioning causes roughly 4% of global emissions, twice aviation
“So I mentioned at the beginning that we're around four percent of greenhouse gas emissions for air conditioners globally, and that's a big number. I think most of the people who are listening to this podcast will be well calibrated to that number, but It's clo…”
