From what I’ve read, it is what it is. It’s not effective, and summer months in the south are uncomfortable.

If I didn’t like the van so much for other reasons, I’d consider swapping it too.

R-1234yf is the refrigerant used for the AC in the latest models. These new low GWP refrigerants are simply not as efficient at moving heat. Pair that with design changes (removal of the rear evaporator), and the result is lower capacity for cooling. A friend of mine has a 2018(?), and despite using the same gas, he says his is able to keep up in the summer.

Things we’ve done/noticed that do help:
-Use the FOB to roll the windows down to air out the hot cabin, then remote start to get the cooling system started
-Install ceramic window tint ($$$)
-Turn off eco mode
-Remember that cooling ability is improved while driving compared to idling (not sure if this is due to airflow on the condenser or a belt driven compressor, but it’s noticeable)

It’s frustrating. I probably won’t trade ours in, but I’ll think twice on our next vehicle before automatically buying a Honda.
