This is my neighbor. It tripped me out the first time I saw them pull into their driveway with your Risinger logo on their truck.

*We liked it **Fastly.Cool** so much in the basement, we bought a second one for the main level. The amount of moisture it pulls out of the air is astonishing.*

Be glad you're building in the south where _MOST_ of the time you only need to worry about high heat and humidity. Here in Michigan we get:
November through March: COLD temperatures and generally dry air, so a humidifier is _needed_ especially if you have forced air heat.
April, May, September and October: Warmer temps (some days you want heat, others you want the AC) and higher humidity where you're going to want the dehumidifier.
June through the start of September: High heat and high humidity.

Yes yes yes! I am setting this up in my home soon. This is such a huge deal that no one realizes. Thank you! Please everyone get your ventilating dehumidifiers!

I once saw it on This Old House - but you take a much deeper dive and would love to see you review a swimming pool - air conditioning cross connect. It basically uses the pool as heat sink to eliminate the need for the a/c compressor most of the year. With the added benefit of heating the pool. Even in AZ, where I am from, it would work almost all year long.

I did this years ago in my own house. Huge difference in comfort. If you’re going to have an air exchange system, you have to have a dehumidifier.

I got an aprilaire dehumidifier last year, added it to my variable speed hvac. To warn you, before you go buy one, you can tell on your electric bill the second you install it! Every rh% makes a massive difference. Ideally you set it at 50% and just go on with your life, but it never shuts off! I live in Houston by the way. My variable speed also has a dehum function, my humidity was over 90% upstairs in summer, the variable speed hvac brought it to 70%, the aprilaire brought it down below 60%. Our average humidity in Houston is over 90% all summer, so if you dont live in similar situation, you probably could set it at 50% and be golden. Overall I have been happy with it, I can't imagine it would cost over 1000$ for someone to install it, its probably 2 or 3 hours of labor, depending on your setup. I also have a fresh air vent, but just close it in summer. Its too much humidity

I had an UltraAire installed a few months ago up here in MN. It's been great for those humid days when it's not quite hot enough for the AC to kick on. Wasn't cheap but the comfort is worth it.

I have a new build and my HVAC contractor is using this. Excited to see this in use!

[zman]

Yup did few months ago, couldn’t be happier. South humid winter it’s horrible.

[masuhari]

I bought this brand new version literally the day it got released. Can’t wait to get it installed!

[johnio]

I added a dehumidifier to my house and it fixed my dust mite issues when it was not hot enough for the A/C to run.

[phxtonash]

Gravel driveway? I got pavement that’s all I got on this house. Very nice. Thank you for the information Matt, as always.

Here in Dallas, Texas, with a one story ranch with oversized but almost brand new HVAC system by remodeler - so humidity stays far too high consistently in spring, summer, and fall. HVAC companies want to “right-size” the HVAC system for $10000+. Not a one of at least 4-5 companies have suggested a whole house dehumidifier. Thanks for this idea.

[BirdDog.]

I figured it would work great for Texas summer to help bring the levels down.

[russcayse]

Did I understand the inlet side of the dehumidifier was connected to fresh air and the furnaces return, and the outlet side of the dehumidifier was connected to the furnace outlets? Wondering if the dehumidifier blower is wired to always kick on the furnaces blowers when it is running? Would not make sense to run the dehumidifier without the furnace blowers on, would not circulate air in the house very well. So, if the furnace blowers are running wouldn't there be higher pressure on the furnace outlet side, fighting the dehumidifier blower? Also, when the dehumidifier blower isn't running, wouldn't air flow backward through it (that is probably not good)?
Shouldn't the dehumidifier outlet be plumed to the furnaces inlet, at a point downstream of where the dehumidifier inlet is plumbed? That way the dehumidifier would condition the air before it hits the HVAC and when the dehumidifier isn't running air wouldn't be pushed through it forward or backward due to equal pressure on both sides (both hooked to inlet)?

I am fascinated by all of the serious thinking and technology. And, I love your videos, Matt! However, I can not help but to also wonder if we could be hurting ourselves by living in completely artificial environments. I have lived in the south and understand how heavy the air feels when hot and humid. However, I also noticed how many people seemed to be unable to function outside of their air-conditioned cars, houses, workplaces. I stayed away from a/c as much as I could for the years that I lived in that beautiful heat and humidity and never seemed to be made dysfunctional by it. Who knows...just sharing : )

You always have great information. It took me a while to find a contractor, but I'm finally getting a ventilating dehumidifier integrated into my hvac system in my new house. The contractor the builder used didn't have the knowledge, so, I went with a two stage compressor and variable air handler since he was well versed in that. So far it seems for at least 4 months out of the year our air conditioner and heat barely run at all. We're down here in Florida. It's great how comfortable our house is, but I've been using a portable dehumidifier for months. I'm ready for the upgrade. We also have a bit of an issue with VOC's in the house. It's pretty well sealed. I crack a couple windows to let fresh air in most days. I'm looking into the RGF Reme LED or Reme Halo products to help reduce VOC's in the house also. Very interesting learning about AQI indoors.

[robwright]

Great info. Our house is new and the humidity inside is high. Never even thought about the fresh air being pumped in. Probably why our humidity level is so high. Wonder if I can reduce how often the fresh air is pumped in?

I need to add a humidifier to my house for the winter.
