lol great job brother

Hello from fellow Iowan, looking to do this myself very soon, any worry about the system being high than the .4 WC max? Thanks

all that video and you can't include where to buy it from.?????????????????

Doesnt it make the house hot and the ac to work harder? And what if it dries out the a coil when system is off because sucking the moisture from it..?

Thanks for the video. Why didn't you just stick the base of the tool in your large vice?

Thanks for the second video excellent and very helpful. Looking forward to installing one in the attic of my 2016 house here in South Louisiana.

Thanks for the video looking at a whole house dehumidifier here in South Louisiana

Such a waste. I put a blade in a vise and use a 40-grit flapper wheel ($23 for 10 on Amazon) in a drill. It takes very little material off and sharpens razor-sharp. A grinder removes way too much material making balancing more difficult. I do sharpen my blades often in this manner. if you're sharpening once a year you're not doing it enough.

Another Chinese knock off hurting an American company. Sure you saved some money but hurt your fellow American workers.

I had the same result! I spent $5000 for nothing and it increased the humidity in my house! so for 12 years I have a brand new April air sitting in my HVAC room doing nothing just laughing at me for being stupid enough to have bought that piece of shit

Have same issue. Unit is running 24/7 but barely reduces the humidity. I hope this method works. Will try this weekend and share the results. Thank you!

What is the blower door air exchange rating on your house?. It doesn’t matter if it’s quiet and you have double doors and double windows The leakage blower test will tell you the truth . When they build the house before the foundation goes down many times, the vapor barrier of plastic is left out, allowing ground source water to come up through the concrete because concrete is like a sponge to infiltrate into the house that you’re trying to dry . As fast as you’re trying to dry it, the moisture comes up . Immediately noticed that 90° hard metal fitting right out of your Dehumidifier that is a no no ., Do not come out directly into a 90° fitting that reduces your airflow that will reduce your output of water. Your output of airflow for every 90° fitting that reduces airflow. And you never put one 90° into a second 90° if you have any installed like this that completely kills the output of any system. Xtreme case I doubt it that you have 10 fish aquariums or 100 plants inside your house . It’s definitely not going to take care of that.. have seen people complain didn’t work, but they literally have a forest inside their house 🤣 It is only rated at the indoor and outdoor temperature specified in the literature at the rated indoor temperature that they require to get that full water removal to their specification . If you attempt to go lower than what they specified for every degree that you go down in temperature, it decreases the amount of water it’s capable of removing . The unit can do it But not if it’s not set up correctly in the right application Get a blower door test and find out where you’re air infiltration is happening.

Thank you for making this! My home is just under 3K sq feet and I was debating which one to go with. I am going with the E130 now. Thanks!

I saw one ofnthe comment below you mention about UV system in your furnace to deal with mold and mild-dew issue. Would you kindly made a video to show us how do you install them

You’re the man 💪. Thank you for the insight buddy.

How do I check if this thing works. It came with the house.

How do you damp it off in the summer?

Dude it says it right on your first drawing that it is hook up wrong. Air is pulled from the supply you have it on the return. Thats why it didn't work

Wow what was the thinking of that first installer? Thanks for the heads up!

Apriair is also junk

This was very helpful, thank you!

Isnt the flex pipe from humidifier supposed to go into the hot air duct?

Great video! for me, if possible, I use the return duct but try to cut in a dedicated supply boot in a central room separate from the supply duct system.

Aren't the All American Bade Sharpeners BLACK? Looks like the chi-com-zon knock-offs are RED. Pretty simple, even for the "enlightened" among us!🤡

A properly sized A/C and build air leaks sealed you wouldn’t have to worry about humidity

Forgot to ask you. When you remove the Honeywell unit was the opening a perfect fit for the Aprilaire 700? Or you need to cut more of the ductwork? Asking cause I have to Aprilaire 600 and want to upgrade to 700 unit

I’m in same situation. I have Aprilaire 600 and solinoid goes bad almost every 2 yrs. 800 model is steam but at almost $2K PLus needs $100 cannister replacement every yr so 700 model seems a great option. But won’t you have same problem with solenoid in 2yrs?

It's interesting that Aprilaire's alternate method is Santa Fe's recommended method. With my Santa Fe dehumidifier it's recommended to either have a separate return for the dehumidifier or connect into the HVAC return, and then provide the dry air to the HVAC supply air in order to bypass the AC coil.

I noticed that HoneyWell have discontinued some models. This may be the reason why. Home Depot still sells them, though. What particular model what this one?

thank you for saving me from buying honeywell

I can live with 200 buck saving just got one for 45 bucks works great well made cant tell difference to the American

Thank you for posting! We have the Aprilaire model 760 and yes you are indeed correct no additional ducts needed. Very simple and works great!

On new builds I’d not even mess around db with the hvac return duct. I set a simple separate return duct system to a;rialirae with maybe 2-3 strategic regsisters in basement areas, and trigger the havc fan to run when aprilaire humidistat triggers so you are confident you are overcoming static, plus you get additional tiem of while hosue fiktration.

Is the a[rilaire fan REALLY strong enough to get through the entire house ducting? What is it about 150 cfm?

Great video-these instructions are nuts.for the reasons you point out.makes you question aprilaire engineering department.

You make great points. Another thing to consider is that warmer air is able to soak up a lot more humidity. Therefore, if you hook up your dehumidifier to the return duct, the warmer-than-room-temperature air coming from your dehumidifier is going to soak up more moisture from your HVAC A-coil compared to the room-temperature air that normally passes through your A-coil.

Your video was very informative. I learned quite a bit from watching it so I do want to thank you. I’m currently running the E080 model and it appears to be struggling quite a bit. My home is approximately 2700 sqft. I connected the return line to the return side of the furnace and the supply side well above the a coil. However, the dehumidifier has been running for more than 24 hours and is stuck at 51% relative humidity. I have no idea what to do.

By hooking it up to the hvac duct work, it seems to me that the dehumidifier is doing the dehumidification the airconditioning would otherwise do, at least to some extent. So, instead of adding a unit that dehumidifies and thereby increase your total capacity to dehumidify (including the air-conditioning's capacity to do so) you are no longer using the airconditioning to its full capacity to dehumidify. Had you installed the dehumidifier separately, you would have had two separate systems dehumidifying. What am I missing here?

I'm going to buy one and if there is anything wanky with it I will send it back. I just can't justify spending $220 for the All American.

What about mold and mildew forming these units? That’s what worries me.

There is no such thing as scam on Amazon. They have the best return policy. Do not like it then return for refund simple as that. I see the same item 1/3 the cost somewhere else. Amazon is NOT always the only place to buy. It pays to shop around and compare.

I got one and it does a great job my blade's stayed sharp for a long time.

I've spoken with Aprilaire about my E100V + 8190FF (fresh air) configuration in the attic, and they continue to recommend a supply-to-return installation. I currently have this setup with a dedicated return for the unit centrally located. I'm experiencing the same issue you've described: warm, dry air pulling moisture from the evaporator coil and redistributing it throughout the house. Between AC cycles set at 72-74°F, I end up with air that is both warmer, around 75°F, and more humid, at 75%+ relative humidity (RH). The system runs almost constantly but never reduces my indoor humidity to the 45-50% RH range; it instead spikes to 55-60% RH after cooling cycles and stabilizes around 52-55% RH. Aprilaire cited two primary reasons for their recommendation: 1) Better air mixing to prevent warm air from being distributed into specific rooms nearby. 2) Utilizing a high-quality filter (in my case, a 4" MERV 13 filter) to ensure that fresh air brought in is well-filtered. I believe the first issue is addressed by wiring the air handler fan to the dehumidifier, triggering it to run whenever the dehumidifier operates-I've already done this. During a cooling cycle, this setup mixes the AC's cool and dehumidified air well, thus not negating the AC's own drying effect. Even when the AC is not running, the fan continues to circulate air, ensuring proper CFM distribution to all rooms. Perhaps I can turn that off so after a AC cycle it work run even room temp air over the coils (like Nest Airwave). I'm a bit worried about the static pressure on my system so will need to use that to guide me. For the second issue the built in MERV 8 washable filter is not the best, but I could easily install an inline MERV 13 filter for the fresh air portion of the return line on the dehumidifier, which has a 6" diameter. As another poster pointed out, in Florida it's actually building code to wire supply to supply; this is specified in R403.13.1. This approach is also backed by experts such as on the "Home Performance" channel with Corbett, Teddy Bear on the HVAC-Talk forums, among others. I'm frustrated that this remains a pervasive issue. Both DIY and professionals are installing these systems in configurations that are less than optimal. Now I'm left with a decision: should I fix this myself or try to get the installer to correct it? Ugh!

Personally, I would have installed a single, dedicated return and supply duct for the dehumidifier. It’s not necessary to supply the dried air to every room. Humidity will move from those spaces to the driest air, especially if the HVAC system is circulating the air.

Brilliant. Thank you!

Interesting. Original desing would work if not at the same time as AC

I just ordered one also. American companies need to stop overpricing products. America’s greed keep us funding China.

Thank you so much for sharing this video. I’m currently dealing with higher humidity than I’m used to inside my home. We’ve just got a new forced air furnace & AC installed to replace our 2006 (original to the house) system. The old AC had R22 refrigerant and it developed a leak, I now know that system did so much better at dehumidifying the home then the new one, likely because of being less efficient and running longer. It has been about a month since new system install and I’m trying to acclimate to it but I can’t stop thinking about it. We were used to having humidity in the low 40% and would run the fan only mode for a few hours to move air around. This would raise humidity but still be under 50%. New system will lower humidity to around 45% at the thermostat and near ducts areas but not entire home, and will settle at around 51. If we run the fan, it will get up to 58% and feel uncomfortable, even at 72°. I should also mention, the new system has a V coil (it’s some new crap technology from ICP)-it’s more efficient at moving air but maybe doesn’t trap enough moisture during operation. We will likely install one of these systems in our home and now know to stay away from moving air for it through the coil. Thanks and sorry for long text here!

Thank you!

Its alway nicer to have a nice knob 😂
