Here if you are in a city (only citys here have codes P&I) you are typically required to have a drain pan and a leak sensor switch to shut the unit off if there is a leak. Still envious of that crawlspace. If you have to have that one it's near perfect. Only way to make it better is to make it a full basement.
You and I discussed this recently, but my Santa Fe died too 🤦♂️. I temporarily replaced it with a Hisense 60 pt from Lowes, then a few weeks ago, that one started getting an error code (E9) 🤦♂️. Hisense is replacing it under warranty.
dehumidifiers is something thats often ignored by erv sales people downunder. i have had people who where not even told of the risks of not having one installed. even a simple gauge just to check humidity levels, especially as they are not testing the house to see if its even worth while. erv's are becoming the new building "fix everything" device :(
My hung @aprilaire EO80 drain pan cracked and couldn’t understand why until I saw the bottom of the unit bowing and I realized that the aprilaire hanging system brackets are not made like the sante fe which has one bracket for each side that runs the width of the unit and thus bears the stress from the hanging of the unit. Did you install four separate brackets into the four feet or two longer brackets similar to sante fe?
Oh nooo 😮 you got one of the old models though. Quest has had the new MCORR tech in them for a few years now, but it's just starting to make it's way to the residential line Sante Fe. Mcorr makes them sooo much more efficient. The Quest 225 uses about the same power as that unit but as the name suggests removes 225 ppd. Oh well, next time.
Not sure if it was ever mentioned in a previous video, but is the flex duct shown in this video without insulation around it? Assuming that is possible because all your ducts are within the conditioned air space. I wasn't aware that non-insulated flex duct was sold anywhere.
I have no ductwork on the dehumidifier in my conditioned crawl space. It is keeping the humidity where I want it. Is there any efficiency benefit in having the intake air a certain distance from the air output?
No, he talked about this in another video. Since humidity sensors detect relative humidity which is temperature dependent, if you put it in before the air handler/heat pump it will be measuring the relative humidity of the air before you cool it down. Since the warmer air can hold more moisture it will read a low relative humidity, then when the air is cooled down to the desired indoor air temperature, the air can't hold as much moisture so the relative humidity will be higher. Thus the dehumidifier won't kick on even when the indoor humidity is higher than you want it to be.
You would want to pass the fresh air through the erv core first; the core will recover the most energy when the delta T is greatest. Then, you can process more if you like. That's how commercial DOAS units work.
@@r.j.bedore9884 This is why you use dew point temperature or grains of water per pound of air for controls; those are absolute measurements of humidity
@@ZergZfTw Unfortunately that isn't how most residential units work, at least not the ones I've seen, probably because human comfort is based on relative humidity not absolute humidity.
@@r.j.bedore9884 This is sadly true... Heck, I'm a mechanical engineer, not software, but I would bet I could build a better control system with some of the shelf environmental sensors and a few lines of Python.
It depends on the local climate (hot/dry all year round). Typically in high performance homes there is good air sealing so the issue is getting rid of moisture released by: humans, pets, plants, cooking, showering. Air conditioning has a dehumidifying effect so if you size it properly you wont need a dehumidifier.
It depends on where you live, how much and how you want to ventilate, air leakage, and lifestyle. Super tight home in Florida? Probably not. Looser home in a high desert environment? You might want a humidifier.
I get low humidity in my house when the temperature outside is low. The humidity can be 100% outside, then you bring that air inside and heat it to 72 degrees. And you end up with 25% humidity air. That is what happens to me in the winter. So I have a humidifier just where I sleep.
A high-performance Home should feel like nothing When you walk inside, you don’t feel the air You don’t feel the temperature You don’t feel the humidity And that’s exactly how a high-performance HOME should feel and I forgot you don’t smell anything
It's like being in a home when the power goes out. That silence is something most people are unfamiliar with in modern times. A high performance home has a similar vibe. It's mostly what you don't feel/hear/smell that makes the experience.
You should get a water alarm or two in the basement for this exact scenario
I agree I have 2 next to my dehumidifier. I like the Govee sensors because they show up in the same app as my Govee temperature and humidity sensors.
The siding on your house has aged beautifully. 👍
Exact same problem with a Compact70 I installed in 2022 having lost refrigerant. Called support last week and waiting for a replacement.

to protect the city?
Awesome! Can't wait to see this.

Interesting- mine is not bracketed, we’ll see if it starts bowing- I’d think the body has structure built in.

the mcorr looks very similar to lgr dehumidifier setups.

For the dehu, no insulation needed, but yes there is uninsulated ductwork in my crawl in general. Check out AC Infinity's duct.
@@HomePerformance Thank you!

What is the ROI now? Should a homeowner escort for equipment replacement every 5 years?
Who said anything about ROI? But I guess if you compare a mold remediation to a new dehu, then yes I can see a pretty great ROI.
Hey brother, what's up with all that staining at 5:27? Install some overflow pans with protection switches on all your equipment.
No idea what you mean about 5:27. Concrete looks like that if it’s not finished to look perfect.
Can you put the dehumidifier in-line with the ERV? Makes more sense to dehumidify the untempered air first.
No, he talked about this in another video. Since humidity sensors detect relative humidity which is temperature dependent, if you put it in before the air handler/heat pump it will be measuring the relative humidity of the air before you cool it down.

What about a humidifier? Are they unnecessary for high performance homes?
It depends on the local climate (hot/dry all year round).
