I bought the AlorAir HD 90 in October, 2021, to replace a 10 yr old Santa Fe unit that died for my sealed 1500 sq ft crawlspace. I did a lot of research before buying this so hopefully it will pay off. In no particular order, here are some of my initial observations after running it for 6 weeks:
1. It appears to be made of good quality materials and it is definitely not underpowered for my purposes. I like the digital controls which my old unit lacked.
2. There is no drain tube included so I reused the flexible plastic line I already had, just make sure to loop the line over itself per the instructions (helps ensure proper discharge of water from the unit).
3. It was really easy to install, just set it in place, level it (a wrench does the trick), connect the power and drain lines, turn it on and set the humidity level. Took about a day to drop my humidity level from 80% to about 55% - just above what I had it set at. I did set the unit on some scrap 2x4 wood pieces to elevate it so it would adequately drain to the sump pit. Don't expect any unit to push water uphill to a drain or sump pit.
4. It is very quiet. I have it sitting under the living room and I never hear it running. It seems to be pulling about the same or slightly less power than my dead Santa Fe unit.
5. The exhaust fan on the unit is pretty powerful. I initially thought that I might duct the exhaust air away from the unit to increase circulation in my crawlspace which is only about 3 feet tall but the unit seems to have no problems keeping the whole area within tolerances.
6. I have a separate remote temp and humidity sensor set up about 15 feet away from the AlorAir unit. I recommend having one so you can monitor your crawlspace and verify that the unit is working properly. The unit seems to keep the humidity with a few degrees from what I set it at so I am pleased with that. The AlorAir unit says it will keep it within 5% humidity from what you set it at.
7. Lots of people seem to complain about the unit dying early in the one star reviews. While mine is new and working fine I will note that even if you were to buy this unit from a professional installer or specialist, they often do not service the units beyond basic diagnostics. So, when these spendy dehumidifiers quit working, you can often be left on your own unless regardless of the model purchased or who you purchased it from. I hope my unit lasts at least 5 years but time will tell.
8. Amazon advertises extended warranty protection for additional fee on this unit for up to 4 years which seems pretty good until you start reading the fine print. From my research, it doesn't seem like this unit qualifies as “houseware” and some customers who buy the Amazon warranties say that Amazon will offer these warranties on products that do not qualify. If your product doesn't qualify for protection then it seems like a crapshoot as if you can even get a refund on your warranty purchase. I skipped the extended Amazon warranty.
9. I bought this unit in part because unlike AprilAire and Santa Fe, you can install this yourself without voiding the warranty. Those other two units require a pro install. It is an expensive unit but I wanted something more commercial grade and hopefully long lasting since no one likes messing around in their crawlspace more than they have to.

AlorAir Demonstrates Exceptional Customer Service: Swift Replacement Resolves Dehumidifier Woes
I was initially disappointed with the AlorAir Basement/Crawlspace Dehumidifier as it failed before the first year concluded, despite promises of durability and a 5-year warranty.However, I'm pleased to report that the company responded promptly to my concerns. They quickly sent out an entirely new working unit, demonstrating an impressive level of responsiveness, assistance, and willingness to work with me.I greatly appreciate their proactive approach and commitment to customer satisfaction. With the replacement unit in place, I'm optimistic about its performance. I'm grateful for the resolution provided and look forward to a better experience moving forward.

Excellent Customer Service for a very good unit. It does the job.
Reviewed in the United States on January 18, 2024
I ordered this dehumidifier in hopes of reducing the humidity in our crawl space. I really like the internal pump so it can easily send the water to an outside drain. The unit shut off within a couple of weeks of installation. Eileen at Aloaire support was excellent in responding very quickly (by email) and guiding me through troubleshooting the unit. When the final test pointed to a failed component, she made arrangements for a return and replacement. The replacement has been operating very well for several weeks now. Our crawl space area was at the upper end of the range for this unit. It has kept the crawl space at the setpoint (55%) with ease it seems. I can hear it cycle on and off, which is comforting. Nice!

Update:
One year and one month after purchase I noticed this unit stopped dehumidifying the air in my basement. I am certain it broke within the one year warranty but I was careless and did not monitor the unit. As long as I heard the compressor working I believed it was functioning. I called customer service and was advised that despite being one month out of warranty it would be repaired at no charge if I would ship it to the repair station at my expense. Then it would be shipped back to me at no charge. I accepted this offer and although the shipping fee amounted to $230 I felt that this was fair since I was careless in not detecting the malfunction earlier. By the way, UPS damaged the unit in transit and the damage was also repaired free of charge. I am not deducting any stars because I do believe it is a good dehumidifier but if it still does not work properly after testing I will edit my review again. I did learn some lessons. All mechanical devices such as dehumidifiers, no matter how robust will fail at some time- some sooner and some later. I expected 5 years of trouble free service. Shipping on an 80 plus pound unit to North Carolina is expensive. UPS is not infallible and damaged the unit through carelessness. Alor Air did the best it could to assist me and I am grateful. If you buy an extended warranty such as the one sold by Square Trade make sure that it covers all shipping costs. It appears that you can not bring this to your local appliance shop in the event repairs are needed. I would still rate the unit 5 stars (unless I have more problems) due to accommodating customer service even though I expected to get several years of trouble free service from it in view of it’s cost and heavy duty appearance. My far less expensive Fridgedaire unit worked for several years until it was recalled.
Update
After the unit was returned to me it appeared to be working. However, appearances can be deceptive. While the unit cycled on and off as needed, I noticed that there was often a pool of water under the unit. Rather than ship it back to the seller I decided to open the unit and inspect. What I found was the plastic tray under the coils was cracked. Water would escape the unit rather than get directed to the internal pump. Using quick setting epoxy and silicone adhesive I repaired the crack. It should be noted that an ineffective attempt was made to fix the broken tray prior to my discovery. I could see that glue had been applied by someone other than me. Having fixed the tray I was certain that I would now have a functioning unit. However, the dehumidifier coils now freeze up almost immediately when turned on (see photo of coils taken after several hours of continued operation, the white is ice). Once this happened the humidifier no longer removes moisture from the air.
From a purchase that I raved about I have become a very unhappy customer. I rarely leave negative reviews but this dehumidifier deserves no stars if that were possible.
I would caution prospective purchasers to avoid this AlorAir dehumidifier. The build of the dehumidifier inspires confidence. It is robust and has hefty weight that inspires confidence. However, it is plagued with problems. The plastic tray was protected within the unit and obviously broken prior to installation. Quality control is unacceptable. The cost of shipping to AlorAir for repair was $230.00. The removal of the unit from the basement and transport to the shipper required two men and was difficult at best. The time the unit was gone from my basement allowed moisture to do harm to the items stored therein or perhaps the mold occurred while I incorrectly thought the unit was functioning. The repair done by AlorAir (replacement of the pump and addition of refrigerant) was obviously incomplete as the technician overlooked the cracked plastic tray or made an ineffective repair of the tray (impossible to tell at this point).
At a cost of $1300. 00 plus the cost to return for repair ($230.00) I am thoroughly disgusted with this product. I thought I was getting an industrial quality dehumidifier when in fact I was better off with the consumer grade dehumidifier it replaced. I would urge prospective customers to avoid AlorAir dehumidifiers. Better to go to the nearest membership warehouse or home improvement retailer and buy a less expensive but more well known brand. Buying this AlorAir dehumidifier was like taking $1530.00 and tossing it in the trash. Lesson learned.

Dehumidifier On Steroids. IMPORTANT - PLEASE READ UPDATE - DO NOT BUY
Reviewed in the United States on October 13, 2017
Not your usual dehumidifier. Nor is the cost. Heavy and appears to be well made. Works as advertised. Replaced a $300 Fridgedaire unit for residential basement use. Since I have had it for just over two weeks I can not comment on longevity. At this price I expect it to last several years at least. A better alternative to having a moldy basement. I did contact customer service prior to purchase to help select the right model for my application. The rep was polite and helpful. I purchased the 90 pint model with pump upon recommendation of customer service. This was excellent advice. If you are not sure of which model you require give them a call. However, as a general rule with some exceptions upgrading will leave you more satisfied and result in less regret.Reviewed in the United States on October 13, 2017
