Hi, Okay I want to use this in my car w/ the widows rolled-up - no hot air getting in. Will it work like the car a/c, or just blow hot air around?

it will just blow hot air around. It may provide some level of comfort, but will never match the level of cooling provided by the vehicles a/c system

It is just a fan. It blows the surounding air around. It does not cool the air.

It will not work like a/c. It is a strong fan (compared to other battery operated fans), so it will give you about a 10-15 degree wind chill cooling effect like other fans. But no, it will not cool like a/c.

I have used the blowing feature in the garage and found it sufficient to move anything I expected (leaves, left-over road dust from road-treatments during the winter, and small other items.) No complaints in that use. I would suspect (although haven't tried it particularly) that it would be strong enough to blow anything in the confines of a car or even in blowing confined areas of the undercarriage or under the hood. I didn't try the variety of nozzles which, in theory, would even more funnel the air and increase the force at the point. Hope this helps with an additional use of what I have found to be a GREAT product.

It seems to blow the same temperature as the surrounding air. As far as I can tell, this is not a mini air conditioning unit.

It should NOT blow out hot air. Your unit may be defective. I'm very happy with this product.

This ting is great, Was. DC area has mid 90's heat with high humidity - blows air hard with rotary dial controller - cools you off fast ! Strong recommend this for anyone driving in heat. R/Brad MacKenzie, Wash.DC Metro

I think it would be good for that application. The only thing that would concern me is trying to use it for both heat and fumes. Carbon monoxide is heavier than air, so you would want a fan mounted low. Heat rises, so this would require a fan mounted high. If this is just for cars that are idling for short periods, this probably isn't an issue. If you are working on running cars for extended periods, you might want to do a little more research.

You have to leave the unit running. When the evap. Is heated enough then the evap fan will start blowing hot air. Wait for this to happen

Of course any/all A/C units generate heat. Yes, you will need to vent the hot air outside or into the attic. The unit comes with white, flexible ducting, which attacked by screwing the ducting into the discharge port on the rear of the unit. Should all be covered in the instructions. No such thing as an air conditioning unit that does not generate heat.

While I have only used for cooling, you can feel some warm air coming from the fan. You must make sure not to have that blocked. The warm air is barely noticeable but I have never had anyone in the back seat where it is placed. I must place my hand against the fan grill to feel the air. Unit works great. I usually freeze a battle of water to act like as ice cube. Very satisfied.

Hello! The fan blows a strong amount of air but will only be as cool as your AC setting allows. Hope this information is helpful!

I don't think that this A/C unit will operate this way, but I'm not 100% certain about this. I believe that the outside and inside air can't mix, but I'm a little unsure about this, since there is a filter of some sort. (Our filter light came on after a few weeks of use, by the way, but I haven't yet figured out how to change this or even if this is critical.)I think that the "fan only" mode merely draws room air through the unit without any cooling.

I doubt it it sounds like you need an air conditioner if it's "very hot". If you had some cross ventilation it might help, but even with two windows a fan isn't the answer in really hot weather.

All this or any fan will do is move around the air that is already there. The act of air blowing over your skin and increasing evaporation may make it feel cooler to you. A fan does not have the ability to cool the air. If it can be positioned to blow the cool air from the front to the back it may help. Insulating the back of a cargo van will help more than anything.

If it is very hot then this fan will only move the hot air around. You'll probably still need a small A/C unit.

The AC works just as it did before I installed it. My two cents worth: even when my Honda Accord was fairly new, the temperature was never totally consistent in the car when the AC was running. The temperature in the car would vary slightly...a little warmer, then a little colder, then the temp would be what I set it at, etc. Not HUGE swings in temps but hopefully you get the picture. Like I say, the AC didn't work any differently after I installed this unit.

It has a small fan in it but I never really hear it. If you have any music or ac/heat on in the car you won't hear it. At least in my uses I haven't heard it.

You need an extension cord. Set the unit on the floor of the car, turn on the car and run the heater or a/c to provide duct exposure, plug in the unit and let it run a few hours. It didn't damage my rubber, plastics, leather or fabrics.
