If you put the ac on auto, it goes to recirculate. I always turn it off if the car has been parked in the sun and is hot inside. 95 degree air cools a lot faster and easier than 125 degree does. And open the windows and put the fan on high. After a minute or so I just press the auto button again. Just be careful, if you leave the fan on low speed, and have a low temp setting, you could freeze up the evaporator. You'll by it getting hotter, and no or little air coming out of the vents. Turn the compressor off, turn off recirculate, and put the fan on high speed. You'll have air coming out in less than a minute. Give it another minute to melt the ice.
It's really only about 90% recirculate. 100% outside air. The ionizer is supposed to clean the air. But it only take the outside air. Seems it would be smarter and better to clean the recirculating air. Maybe it just cleans the evaporator.
What's the ill effect if we leave the ionizer on? I've heard specualtion...but it's not an ozonator after all. That is bad for sure even for short periods. Any help understanding is appreciated. I live in FL where there is high high high humidity. Recirc lets me dry it down. Mucho essential. I will say the car does auto set recic/fresh well for most people. I just demand low humidity. If it's over 45% I'm quite uncomfy. I'm shooting for 30-40%. I'm like a walking hygrometer.... Got my house dried down to that too
I was stationed in Texas. It get HOT there! It's 90-95 degrees outside. But inside a closed up car, it will get 125-130 degrees. Which do you think will be easier to cool? And which is faster? Once it starts cooling, you can turn on the recirculate. If you have the temperature to the coldest setting, and the fan on the lowest speed, the evaporator will freeze up.
You can demand all you want, in Florida in the summer time it just AIN'T gonna happen. Start the car 10 minutes before you get into it with the AC on. That's about the best you can do. And.....what is an "ionizer" ??
