Looks well made and was very well packed!

I've got a sealed crawlspace under my home that needs dehumidification. I bought this unit because it is short (not a lot of height in the crawlspace) and had a ducted option, which helps me circulate dry air around several large obstructions in the space. The unit was double boxed (dehumidifier w/ 4 foam corner brackets in a box, then that box was padded and inside another box). There was a hole punched in the outer box during shipping, but the inner box was still intact and undamaged. The unit itself was in perfect condition and started right up. The unit felt very industrial and was well made. I opened it up and took a quick look around. Components were well made, and electrical connections were solid. The filter is easy to remove and reinstall after cleaning. The controls were intuitive. I also bought the additional remote control (on a 25" wire, provided with the unit). I was happy with that (it allows me to check on the humidity level and change settings without crawling on my belly to get under the house).
Nice dehumidifier!

A remote controlling sensor is available with a 25-foot cable to enable full separation from the sensor from the evaporator coil. The unit has a MERV 8 removable filter to keep the coils clean. It is very quiet when operating. The only way to tell if the unit in the crawl space is running is to put my ear against the floor to hear it as the sound is too faint. Additionally, I highly recommend the hanging unit when installing. The rope system minimizes the conduction of vibration, and it raises the unit to get more height when running the gravity drain pipe.
Great well designed unit!

I finally decided to quit buying junk and started researching crawl space dehumidifiers. Most crawl space dehumidifiers are overpowering for my needs (100 ~ 200 pints per day). The Alorair HD55 is one of the smallest crawl space dehumidifiers on the market. And it is a quality design. This unit has a coated coil (in which the aluminum fins and copper tubing are coated). It is held together with stainless steel plates, protecting against premature evaporator coil failure due to formicary corrosion. Secondly, the humidifier sensor is separated from the evaporator coil and is located on the lower end of the unit to minimize triggering by evaporating moisture from the evaporator coil.
Get this unit!

I was initially terrified to buy a commercial unit for my crawlspace, but the household ones don't last longer than 18 months. I did a lot of research and just wanted an essential resolution to my problem. I'm so glad I got this unit! Initially, experiencing sticker shock, I was afraid to purchase online, afraid it would arrive damaged. But I didn't find this style unit locally, and any other merchant was scarier than Amazon, which always makes things right. This thing was packaged well and a breeze to install. I gave it two hours to rest from shipping before I put it to work. I have a 1200ft crawlspace with partially buried concrete walls and a poorly installed plastic vapor barrier that doesn't cover the entire floor. Humidity was saturated for months at >70%. This unit got the moisture under control in under a day! It's maintained beautifully a month later, coming on about 3x per day. It contrasts the household unit that was 3x-5x per hour. I know there will be energy savings on that alone, and I hope it lasts a long time. I'm irritated I didn't buy this sooner!
Just installed - looks well made and was very well packed - fired right up.

I have a decent-sized home which includes a 1500 sq ft finished basement and a garage built on a concrete slab that is about 500 sq feet. The concrete in these areas, plus the basement is below ground level, creates a substantial moisture issue. I have run 2 dehumidifiers Simultaneously in the past in my basement alone. In comparing the performance, the sentinel amazed me by pulling more moisture in a shorter amount of time all with running less often. I’m going to save on electricity as well by running 1 vs 2 at a time. My mother-in-law lives in our basement and she is pleasantly surprised with how quiet it runs. I’m very satisfied with the product. The sentinel is lightweight and easy to carry/move. Comes with a very nice drain hose and easy to remove / clean filter. One other side note- I’ve had a dehumidifier and other mail packages arrive at me In the past damaged - I highly doubt you will experience this with the sentinel as it is very well packaged. Overall very impressed.


Would it collect water outside?

The unit comes with a drainpipe, and it only drains through gravity.
Is it a limited warranty? What are the warranty terms?
