Tools and Hardware Reviews of Frigidaire Dehumidifier, 70-Pint Capacity, FAD704TDP

Customer Review: A note on noise level and heat generation
Summary: 5 Stars

Have had the Frigidaire 70 pint unit for about 3 weeks now, and am quite happy with the purchase so far. I got it for the fairly large basement of a 150 year old house in Upstate NY. The first day I ran it in the bedroom just to see how it worked.

Noise: It is definitely not silent, but I'm used to a 12000 btu window a/c unit running all the time and compared to that this dehumidifier is quieter. On the other hand it is quite a bit louder than a refrigerator. It really boils down to your tolerance for white noise. I prefer white noise while I am sleeping, but some do not. You can cut down on the noise some by selecting the low fan speed, but the compressor noise is the same (while the compressor is running) regardless of the fan speed. The compressor cycles on and off depending on the humidity set point you input, or you can set it to run all the time.

Heat: A note on how dehumidifiers work and why they heat up the room they are in; they have an internal refrigeration compressor exactly like the one in an air conditioner or a refrigerator. Depending on the capacity of the unit (pints per day it is rated to remove) that refrigeration system will be bigger (ie draw more power and likely be louder) or smaller, but they ALL have a refrigeration compressor. During part of the refrigeration cycle the compressor, as the name says, compresses the refrigerant gas inside the system. That creates heat. All compressors do this, whether in a refrigerator, freezer, air conditioner or dehumidifier. With an air conditioner the heat is ejected to the outdoors, along with the heat collected from the room, hence the room gets cooler (and less humid). With a refrigerator and a dehumidifier there is no connection to the outside so the heat created by the compressor stays in the room. Put your hand by the bottom of your refrigerator when you hear it running and you will feel warm air coming out. Dehumidifiers work EXACTLY the same way. All of the comments I see (not just for this unit) about some dehumidifiers NOT heating up the room are, for want of a better word, ignorant. There is no magic dehumidifier that does not produce heat, just like there is no car that does not require fuel. It is physics.

The main difference between dehumidifiers, then, is how much power their compressor draws which depends on what the humidity removal rating is. That heat, however much it is, is going to go into the room the dehumidifier is sitting in and warm it up. This unit is at the high end of portable dehumidifier capacity, at 70 pints per day, so it has a larger than average compressor inside. That means that while the compressor is running it will put out more heat than a lower rated compressor. Keep in mind that the compressor does not necessarily run all the time. If you set it to turn off at a certain humidity the compressor will turn off once that humidity set point is reached. However, the fan will continue to run at whatever speed you set it at, high or low, regardless of the compressor being on or off. The only time the fan turns off is if the unit shuts off due to a full bucket.

All of that said, this unit in my fairly large bedroom raised the temperature from 75 to about 80, BUT it dropped the humidity from 65% to 45% in a short time and I FELT less hot, even though the room was warmer. (Your body gets rid of heat by sweating. The lower the humidity the more efficient the heat removal by sweating is. With very low humidity your sweat evaporates so quickly you may not ever "feel" sweaty, you will just feel cooler.)

As noted by others, the internal bucket is only about 2 gallons while 70 pints is nearly 9 gallons. If you plan on using the internal bucket you will need to dump it at least a couple of times a day if you are in a high humidity environment.

After my bedroom experiment I put the unit in the basement and hooked up the drain line to run into my basement sump. All it takes is a hose with a standard garden hose female connector on it. I made one myself using a section of old garden hose and a female adapter from the hardware store. It took a few days and MANY gallons of water pulled from the air, but my basement has gone from over 85% humidity to under 60%. It would go lower, but my research says that mold won't grow under that amount, so you aren't really getting any more benefit of the power it draws to lower the humidity any more. The temperature down there went up a few degrees from around 68 to 71 or so. The damp smell, which had even been making its way up into the house on the hotter days, is completely gone. I am also no longer afraid to use the basement to store stuff for fear of mold damage.

One thing I'm not sure of is longevity. Searching through reviews, every single manufacturer out there seems to have a tale of early failure for every tale of long life. Only time will tell on that point, but so far I am very happy. Especially since this unit costs less on Amazon than units of half the capacity at the local home supply stores.
