mk cant log in I have 3 Frigidaire 50 pint units, one in my office basement, one in my detached garage, and one in my crawl space at home.

All three are 10 +/- years old, bought at Lowes, no problems. I run them about 7-8 months, turn them off in winter. Clean them every year or two.

Bill Krejca Thanks for all the suggestions/thoughts. In two years, I will probably need another one, so, I'll rephrase my question to ask how those suggested (or others)have held up, and go from there. The folks on WC never cease to amaze me with their friendliness and willingness to share!

Pooch Most basements have limited air circulation and it doesn't have to be a wet basement for there to be a dampness trapped down there. Mustyness follows humidity.

I actually run two dehumidifiers all year around. During AC season they will run. During winter heating season they seldom run. It is during the in between seasons that they are invaluable.

Our basement is unfinished and over a hundred year old poured concrete walls and eight foot deep. Being that deep in the midwest, dampness constantly wicks through the concrete. Walls are never wet, but you can smell the evaporating dampness. Dehumidifiers very much reduce that while protecting everything I use the basement for. Small wood working shop, a reloading bench, a fishing bench, a room full of model railroad and every thing else that a basement is used for.

Years ago I learned a trick by accident about our HVAC system. When we totally rebuilt our home over twenty years ago, the HVAC guy undersized the return air causing the furnace to short cycle. I cut a hole and installed a vent in the main return plenum to allow the furnace all the return air it needed. By doing this, much of the return air is drawn from the basement and redistributed to the upstairs. In the winter this brings some humidity from the basement to the upstairs and in the summer the return air is picking up cooler air from the basement to the upstairs. This setup does not seem to have effected the balance of the system. Leaving the door to the basement slightly ajar for the cat actually helped overall. Now don't all you HVAC guys get your britches wadded up as this works well for me, but doubtful for others.

If all of the respondents about dehumidifier's do not have an all house air conditioner - no comment.



But if any of the respondents have an all house air conditioner, let the air conditioner take care of your humidity issue.



This does require that the air conditioner can move air into and from the area that needs to be dehumidified.



But any full house air conditioner that is correctly sized for a home will remove virtually all of the humidity in a home with no issue what so ever.



I know that in our home here in central MN. we will often drain (a guess) 10 gallons of water a day out of the air in the home.



The amount drained is a guess because the outlet of the air conditioner goes directly into the floor drain, so I can't be sure on the amount of moisture leaving the air conditioner.



Take care
The first house my wife and I bought was a ranch with hot water baseboard heat. With no ductwork, when we had AC installed, they installed the airhandler in the attic space with the ductwork in the attic and the vents in the ceiling. The ductwork was 8" round, flexible insulated tubing. The ceiling vents were circular. All of the vents were towards the exterior walls and the return was in the hallway ceiling.

In any event, with no ductwork or return in the basement, when we finished it we needed to run a dehumidifier down there, especially with the washer and dryer down there.

Not sure if thats why anyone else runs one, but that's why we had to.

In short, no REW.

Lazy Ike I have the following unit, https://www.sylvane.com/santa-fe-adv...umidifier.html . I was getting a few years on cheap units and always feared the fire stories. Thus one works well. Less runtime and on a lower setting. One filter a year.

gbin I likewise got tired of overpaying for cheap Chinese-made [email protected] that lasted only a year or two - and the compressors of virtually all of the dehumidifiers for sale in the U.S. are made in China, even if other components and/or the casing aren't - so a couple of years I tracked down a REAL made-in-USA dehumidifer with a stellar reputation. More expensive up front, absolutely, but not designed or built to be anywhere near so disposable so it should ultimately much more than make up the difference:

Quiet, but fairly heavy. It really brought the humidity down in my basement more than any of the cheap big box units ever have. Time will tell, but so far it is outstanding.

Man, looks like a mega heavy duty unit. Share a working history on the unit as years go by, I'm not due for another new one 'til 2023!

REW Pokey,
Thanks for the picture.

Bill.
Correct on the assumption.

Inside the tank is the motor and the compressor pump - as well as the weight of the sealed tank as well. Thus you have a heavy assembly.

Also, as other posts have said - if you are having trouble with the motor, compressor, or a leaky tank - the typical venue to pursue; is to scrap the current dehumidifier and purchase a new one.

The motor/compressor/ tank assembly is 90% of the cost of the dehumidifier.

Best wishes.

-------------------------------
Many years ago, my father had purchased a window air conditioner that contains essentially the same sort of sealed tank, compressor motor assembly.

Due to the location and the location of power a different power cord needed to be installed on the unit. At that time I had done a lot of wiring so my father asked me to take care of the job.

I was in a bit of a hurry due to other jobs that needed to get done and I went to work. However, I had not unplugged the unit from the 110V ac. As a result, after disconnecting the first wire from the power bus, that wire was loose accidentally landed on the tank containing the motor and pump and refrigerant. The resulting spark became a mini welder and burned a hole through the tank. The hole resulted in a loss of all of the coolant on the brand new Air conditioner unit. As expected, my father was unhappy. So, the next time we was going to town, he loaded up the AC into the truck and took it into the electrical / refrigerator shop in town. They welded up the hole, and reloaded the A/C unit with freon.

When the A/C unit came back - with a longer cord, my father suggested that I not repeat the same mistake again. I assured him that I had learned from my mistake. In all of the years since, I have never ever failed to disconnect power - before working on anything powered by electricity.

That was one thing that I really appreciated about my parents. We were given the tools and the instructions on how to start the job and gave us free rein to get the job done. We did make a mistake from time to time, but as my father said - just part of the cost of having the children educated.
