I checked the Owners Manual for my 2014 and the description of the Max A/C button is:

Turns on the A/C, selects airflow
from the dashboard vents, and
switches the mode to recirculation.

Nothing about increasing the fan speed, which is a separate control.

I've never owned a vehicle that selecting "max a/c" changed the fan/blower speed. Does selecting HI fan speed work?......if so, you are good.

Econ off makes a difference in AC performance. Setting to automatic helps a little as well.

Funny you should say that because every car I've owned including my current Mustang (2012) when on Max a/c blows at a higher speed.

I'm just stating my a/c experience which is the same as post #2 and the 2014 Honda manual. Basically, max a/c is recirculate.......air is taken in from the cabin and passed thru the evap (recirculated). Max a/c, or max cooling, is simply recirculated cabin air. Fan speed can be set to low, but the system can still be in max (recirculate).

What matters here is what do Hondas do.

For Hondas...check the actual blower setting display. MAX simply changes from external air to internal air recirculation (and may or may not increment the blower setting too when in Auto .... unless it is already at MAX) ..... which sounds louder as a result.. but does not actually represent a higher fan setting.

As already noted by someone else ... ECO will degrade AC settings.. but mostly with respect to the compressor I believe.

Auto is the way to go with newer Hondas... as the car does all the work of monitoring and calculating what is needed... including switching in and out of MAX (which again... simply changes the source of the air).

2015 EX does not have Auto. When do you go on vacation? PLEASE

2015 EX does not have Auto. When do you go on vacation? PLEASE

I know it doesn't I just figured why bring it up it would just lead the conversation in a different direction ?

Wondering what “ECO” mode changes regarding a/c? I see no change in vent temp whether in “ECO” or not.

The Owners Manual for my 2014 CR-V doesn't have any details, it only says:

The ECON button turns the ECON mode on
and off.
The ECON mode helps you improve your fuel
economy by adjusting the performance of the
engine, transmission, air conditioning system,
and cruise control.

One of life’s mysteries........how “ECO” mode changes a/c.

One of life’s mysteries........how “ECO” mode changes a/c.

Honda's ECON mode is – as you might expect – a sophisticated answer to a relatively simple question. Here's what Honda reported:

"When the ECON mode is activated, several operating characteristics of the vehicle are modified for enhanced fuel efficiency. The drive-by-wire throttle system provides more gradual response and, to save additional energy, the climate control's fan speeds are lowered incrementally, while other climate control system characteristics are altered based on the conditions. So the climate control will be slightly less aggressive in maintaining a set temperature (this saves energy) and the cruise control will also be slightly less aggressive in maintaining a set speed. Allowing more variation saves energy as well."

Honda won't attribute a percentage improvement because, as they indicate, there are simply too many variables.
