Input:
Question: Does the fan run constant when in AC mode, even when the compressor is off? Or can the fan be set to turn off, like "energy save" mode on window unit?
Document: It claims to run quiet, and it does - in comparison to a box fan or a window AC unit. If I load a voice chat program, however, I have to turn the fan down to its lowest setting, or it overwhelms the microphone. It's not exactly deafening, but you're going to notice it.Efficiency. As others have said, neither the vent hose nor the window sealing are insulated, allowing a decent amount of radiant heat to be shed back into the room.
this item has a thermostat which I would expect to turn the unit on and off but the fans runs all the time with the compressor turining on and off with the thermostat. I just neede a backup AC for a computer room to kick on the once in a blue moon when the Liebert gives out for one reason or another.
Similarly, there's no indicator of fan speed settings - you toggle through it, and hope you remember accurately how loud the 'low' setting was.Overall, four stars. Drawbacks are superficial or annoyances rather than functional, and in most cases are simple enough to mitigate or correct. Functions as intended, good price for the output, easy to set up and run.
The portable unit seemed like a great solution and would allow me to move the unit into the bedroom on hot nights also.According to the sizing chart, the Honeywell MF08CESWW should have been more than adequate for my office. I installed it, even wrapping the exhaust hose to the window with insulation in order to improve the unit's efficiency. But the unit simply could not do the job.
When there is excess water condensation the unit will stop. There is a drain plug on the back of the unit to drain the water. Not sure how often that will need to be drained. And, a five year warranty.All in all a very easy portable AC to set up and use. I can move it to other areas if need be, and when not needed roll it into my closet until it is needed again. The noise is fine, softer than my old Window AC.
I bought this to use in my pop-up camper, which is a small model that isn't braced for a roof AC unit (8ft box).This is a large unit, but I'm using it on a counter near the door and run the exhaust to the screen on a bunk, and zip around it.It actually does cool the camper! In 100 degree heat it can't really keep up, but it makes a difference.
Purchased this unit on the strength of other reviews however, after 3 months of use I can say that this unit is not all that it is reported to be. Yes, is does blow cold air, if you set right in front of it, otherwise the exhaust heat radiated from the hose cancels out any overall cooling effect and actually raises the room temperature. Insulating wrap does help some but is an added expense. My biggest complaint is the claim of the dehumidifier mode, it doesn't work.
We don't know yet,what this will do to our energy costs,but Honeywell claims this unit will run only about $37.00 dollars a month,with regular use. I will add that Amazon sells this for alot less than Lowes and it came highly recommended to us. Fingers are crossed,but,at this point we are totally pleased with our purchase and recommend it to friends.
We bought this unit in July, 2013 to cool a medium size closet. The unit was  easy to install  and reasonable quiet. It cooled well for about two months, then stopped cooling (the fan and compressor were still running, but the output air was no longer cool). I called Honeywell, and the representative there was very courteous. He asked me to send him a photo of the product label, which I did, and Honeywell immediately shipped me a replacement unit (they paid for shipping).
Overall this AC unit is okay and I like it. I purchased it to cool a network gear closet. It replaced a Solaris model that we have had in their for almost 5 years.Pros:- Inexpensive.- Short height - it needed to fit below the swing out of a wall mounted equipment cabinet.- Cooled the closet down quickly. The closet is about 50 sq feet with an 11 ft ceiling.
Answer: I Don't think there is a way to not use the fan
