Waykar 158 Pints Crawl Space Dehumidifier with Remote Control up to 6,500 sq. ft., Dual Duct HVAC Commercial Whole-House Dehumidifier for Basement, Industry Water Damage Unit - 5-Year Quality CoverageRecycled Claim Standard Blended

I purchased this unit in March 2024. It ran great for 1 season. I started it up for the humid season in April 2025 and it did not work, it would turn on but would not remove humidity from the air. After emailing customer support and going through a few troubleshooting processes, it was determined the unit was no longer removing moisture from the air. They sent a new one and asked that I leave a review of my experience. Because they did honor their 5 year warranty and promptly sent a replacement unit, I'm leaving 5 stars...now let's hope I get more than one season out of the replacement unit. The replacement unit is working great and dropped the humidity from 64% to 49% inside of my 1500 square foot home overnight, while humidity outside remained at 100% overnight. Humidity continues to drop the longer I leave it on as now everything in the home must dry out.

This dehumidifier is a great buy. Easy to install and you are able to keep it a stand alone unit or pipe itInto your existing hvac system. Can see a big difference in the humidity in my house. Also customer service is great!

Bought this Waykar 158 Pints Crawl Space Dehumidifier for my basement. I like that it can be ducted to blow in multiple room. It worked great for 22 months but has stop working. Waykar customer support team has been a great help to find the problem. They reply promptly with clear solutions. Unfortunatly I'll have to change the unit but they will send a free replacement.

** See updated review at the end, Waykar has said that they are changing their policy on how they work with customers needing help replacing defective parts**— Original Review = 3 Stars —I have a super low ceiling crawlspace, about 12” in some places. It has a dirt floor with vapor barrier on it. The crawlspace about 900-1000 sq ft and it has a wall down the middle splitting it approximately in half. So it was a tricky situation that this unit seemed perfect for.I purchased this unit in November and I was able to manually turn on and off the unit. The dehumidifier seems to do a good job removing humidity from my crawlspace. It is not super loud. I was able to locate the unit in my basement and run the ducts for the intake and exhaust ducts in through access holes that were on either side of the dividing wall of the crawlspace. My hope was to be able to have the unit outside the crawlspace with the sensor inside the crawlspace and that way I could service the unit. And also my crawlspace was too small to fit the dehumidifier in the crawlspace.But unfortunately it was not able to work automatically which was why I purchased it. I could turn on and it would run but the remote thermostat would say that the humidity in the crawlspace was 99% and because of this the unit would constantly run. It was also displaying an E4 code from the first time I started up the unit to know. As I understand it that means the sensor is bad. I did place a separate hygrometer in the crawlspace to see what the levels actually were and as expected they were never 99%. And I could see that the dehumidifier was actually working and lowering the humidity in the crawlspace.I did not prioritize reaching out to Waykar about this issue as we had quite a lot going on in our family.I finally reached out in February and they explained that my sensor was bad and requires replacement.They also told me that as my order had been over 30 days that I had two options:#1 “The price of the humidity sensor is $25 and the shipping fee is $15. If you want to buy one from us, you need pay to our PayPal account. After that, please send us a screenshot of payment and your PayPal account to confirm. Also, please email us your shipping address, then we will arrange the replacement to you as soon as possible”#2 “ We could send you a replacement part for free if you would like to write a review to share your feelings and thoughts about my service on Amazon.Also, please send me a review screenshot to check, then I could have the right to apply for a free replacement accessory to you from my company.”As #1 made me a bit uncomfortable I’m going to try #2.I will say that I was able to get ahold of customer support via phone and they were responsive via email.So we shall see what happens after I leave this review.I’m hopeful that I get the replacement sensor, install it and the whole setup works automatically as I hope. I do wish that I didn’t have to jump through these hoops.**UPDATE**Waykar reached out to me after posting this review and apologized for the complicated process to receive replacement part. They said they are planning to make changes to their process to eliminate some of the confusing steps.They actually sent me 2 replacement sensors in case there was ever an issue.When they arrived the replacement was very easy. I crawled into the crawlspace to the access the defective sensor, unscrewed the screws and unplugged the old sensor. Then I plugged in the new sensor and put it back together. The thermostat began working correctly immediately. And it has been working ever since.The one thing I have noticed is that the humidity level rises about 5% above the set level before the dehumidifier kicks in. No big deal, I have just set it 5% below the highest level that I would want the crawlspace to rise to.Overall I think that this is good choice for this application and I am going to give it 4 stars

This is the best dehumidifier I've ever used. After three years, I encountered some issues, but Waykar's customer support was exceptional—quick to respond and genuinely attentive. They resolved everything, and now the unit is running smoothly and is remarkably quiet.

They do make a lovely metallic pinging noise when struck by a projectile of any caliber., even a .22.As seen in photo, I had 2 of these heavy @$$ machines. Each, I dollied allll the way to the 3rd floor.1st unit worked for a year, tops (though I suspect much shorter)Seller replaced it as long as I left a good review. It was right around a year when i contacted them.2nd unit never worked as far as I can tell.FYI- if the unit powers on, that only means it’s using electricity, nothing more.2 easy ways to know if a dehu is working:- if the unit is set to a lower humidity than ambient air, and it’s running, there should be water accumulating wherever the drain hose is ran. No water= not working. Just using an @$$ ton of electricity- when the unit is turned on; within a minute, you should hear the compressor kick on (like a refrigerator). It should click and then you should hear a mechanical humming noise that continues until the unit cycles off. If you only hear air blowing, it’s not doing anything but sucking up air and blowing right back out.And that is all both of these units would do for me. Great workout getting the beasts up and down to the attic.Once I’m done shooting them, I’m going to use the loader to lift them as high as possible…the release and watch them smash to the ground.They ARE heavy units and APPEAR well built from the outside.I replaced it with the competitors model that is similar stated specs but costs $500 more.Pay the extra $500 and go with a more well known brand. From my experience.
