Oasis D-165-HG GST Commercial Grade Dehumidifier

I ordered the Oasis D-165HG after two Chinese manufactured dehumidifiers died, each after only two years of operation. Both were made by LG (one Kenmore and one GE) and suffered refrigerant/oil loss.The D-165HG is a bit pricey and not terribly efficient but if it lasts a long time it'll be worth the expense. It's old technology using a Tecumseh piston compressor made in Brazil and a sealed Morill fan motor made in Tennessee. I know both of these major parts to be of high quality. The remaining materials and workmanship appear to be good.Packaging for shipping wasn't so great. It was covered by a cardboard box and strapped to a tiny skid. When it arrived the bucket full light was pushed out of the front panel. I pushed it back in. When powered up it worked perfectly with one exception, a rattle when the hot gas defrost cycle kicked on. I found there are two rows of expansion coils and the rear most row was pushed in, so it tapped against the front row when the solenoid opened. I gently pulled them apart and no more knocking.It's a very quiet unit and it pulled the cool basement humidity down as quickly as the two 65 pints/24 hours rated LG models, although it's rated at 30 pints/24 hours. Under what conditions do they rate these things? Frankly, I find the LG units ratings hard to believe.The warranty is one year, customer pays labor and transportation. There is a five year warranty on the sealed refrigeration system, customer pays labor and transportation. So the warranty isn't very good but I expect this unit to last a very long time given past experience with similar designs if being made in Poland means quality workmanship- we shall see.Added 8/20/2012After some reflection I believe the reason the bucket full indicator was pushed out and the evaporator coils had shifted is due to the tiny skid raising the center of gravity of the package, making it prone to toppling and increasing any resulting damage. I also noticed a series of dings in the condenser coil fins that line up with the bottom ends of the innermost section of the evaporator coil. I believe that during shipment the package tipped over onto the face side of the dehumidifier.Still working great after 4 years of continuous service.

I ordered one of these dehumidifiers and it did not work. Because of my long search for a good dehumidifier I ended up learning about them. So I decided to troubleshoot it a little. I found out that the coils were not cold behind the filter on the top back of the unit. I opened the front cover (three Phillips screws underneath) and found that when I turned the unit on the compressor did not turn on. Fan and Compressor make very different noises, so If you can only hear air blowing, the compressor is not on. I saw in the bottom back left corner that one of the wires was off of its receptacle. I unplugged the the power and plugged in the loose wire. Then plugged the power cord into the wall and fired it up and the compressor coils instantly chilled.So far after that issue it has been working nicely. This was almost a 1 star review. While I was poking around the insides I could see the nice workmanship and good quality materials. No Plastic parts internally. Hopefully it will last a long time, my last dehumidifier broke in a year. This is why I figured I should spend more to get a well made unit, because $200 every year gets more expensive if I live longer than 3 years. Which I plan to do. Will revise in the future if anything changes.Update: March 2018 Unit is still working fine. Some dust buildup in areas that are not the filter, but i just need to blow it out.

I received the unit, packaged fairly well. Others reported damage from shipping, mine wasn't damaged. So far the unit runs quietly, is removing a lot of humidity from my damp basement. After only a few days of running, it has almost eliminated the damp, musty smell from the basement. It took me three months to find a replacement unit for the cheap units I've been using, so the moisture build up was driving this purchase. I'm currently using crutches to get around, so trips to the basement are seldom. Because of this, I attached a hose to the unit to drain into my sump pump directly out of the box. I noticed some water on the floor around the unit. Turns out it was the fitting on the hose. Bought a new hose and I still see water puddling up on the floor around the unit. Quick peek shows the water not draining from the drip pan into the drain hose, but overflowing the edges of the pan. I turned down the sensitivity of the unit to see if it was drying faster than it could drain. When I'm a little more mobile, I will take a look at the drain pan and try to find a solution. Otherwise, pleased with the unit. Quiet running, and solid build quality. I hope it will provide me more than a few years of service.=======================After another trip downstairs, I still found water around the unit. I noticed the unit was on a slight slope in the floor. Leveling the unit has solved the overflow from the drain pan. While I'm impressed with the unit as a whole, I'm disappointed by the shallow depth of the drain pan. The unit is sensitive to the slightest variation in the angle of the floor.=======================Five year update.After five years, almost to the date of purchase, the unit is still running. The humidistat seems to be sticking, which keeps the unit running all the time. Tapping the switch allows me to adjust the sensitivity and the unit goes off. Kind of disappointed I can't find contact information on the Oasis website. Would like to talk to a technician to diagnose problem, and order parts. Still happy with the purchase. Does a fine job of controlling the humidity in my basement.

At a little over $500 bought in 2015, the material cost was over $100 a year. The typical $200 dehumidifier generally last two years, about $100 per year.The compressor was drawing 40 amps when it kicked on and the built in overload would kick out in about a second. The overload would automatically reset in about 10 seconds and the cycle would continue. I was surprised it never popped the breaker as it is a 20 amp circuit.
