I installed this with the optional hanger kit in a dry (but damp) 1800sf crawlspace that was averaging 75-80% all the time. I foam board sealed the foundation vents, set the dryness to 50%, added 10' of flexible duct to each end, including a Y on the out to divide air direction. It ran continuously for several days, but now that I'm a couple months into it it only runs once or twice a day for an hour. I did not notice a spike in electric bill. Crawlspace only has black plastic down, but it is full coverage and taped at seams, on a bed of fine gravel screening. The musty smell is gone, comfort and quality of air in crawlspace and house is wayyy better. I had some issues with a "droning" sound coming up into the house from the unit, but played with the ductwork a bit and it seemed to help. Not sure how long the unit will last, hopefully a long time given the price. I like to think you get what you pay for.

Purchased the 90 pint dehumidifier and pump. Wood moisture readings previous to encapsulation were 18-25% with humidity readings of 80-85% . Wood readings post encapsulation are now as low as 6% some places and cant find a reading over 15% anywhere. Humidity is now steady at 53% with the dehumidifier cycling on and off. Highly recommend the fan kit to improve dehumidifier efficiency as my 90 pint is on the edge for my 2400 square feet crawlspace but it seems to be working well and cycling on and off instead of running constantly. Great product!

I'm a small contractor in East Tennessee. After installing no less than 60 units, I called AprilAire one day and asked "What do we do if we ever have a problem?"

In short, the he said "If we replace it, the 5-Year warranty starts over.

Change the filter in June and December and expect 15-18 years of service, minimum. Best unit on the market, Period !!

Item was priced reasonably, compared to two other units that have failed in less than 2 years. Adam was shipped quickly and arrived in good condition. Set up was easy. Warranty for 5 years is the best.

I purchased my Moisturizer Medic HC70 to replace my Santa Fe Impact that started needing recharging every year after the warranty ran out. I have had just over a week and am very happy. It is a little more noisy, but I can live with that. Performance is what impresses me.
