- Air to Air Exchanger (HRV or ERV) and Humidifier Summer Setting. In this video I briefly go over what the air to air exchanger and humidifier settings should be during the summer along with some basic maintenance on the air to air exchanger. How to clean the filters inside the exchanger box and the inlet screen outside. I did not mention this in the video but the humidifier also has a water panel in it which is sort of like a filter that needs to be replaced once a year if you use your humidifier often during the winter.

Thank you so much for explaining the basic knowledge of operating HRV and humidifier. I have the same setup in my house but this is my first time knowing how they should be operated during summer.
I am pretty sure my builder walk through said EVERYTHING exactly opposite . Thank you for the clear instructions and explanations.
I learn a lot from your videos. Usually I am in favor of getting things done by pros cs I am an Engineer myself busy with job but honestly there are too many
fake and non qualified folks who don't know nothing and forcing me to do furnace and AC Unit service myself.
I'm happy to hear that my videos have been helpful and sorry to hear about the bad experiences with companies! May your repairs be successful and infrequent, stay cool!
Well Jay, you showed me something I’ve never seen, and I’ve been doing hvac for many years. Cool.
Another great video, Jay! You're channel does not get the recognition it deserves. I have tried to share your channel with anyone who needs HVAC advice since your videos are well done. Cheers!
Thank you! I appreciate the support and am glad to hear that you are finding the videos helpful! Thanks for sharing, stay cool and have a wonderful week!
Thanks for the awesome advice!
This changes everything I thought I knew about HRV’s
I hope it is a positive change 😅
Great tips!
Jay. It's been so long since I've seen one of your videos! I don't know why. I lived for them. Last ones I saw were in Hawaii. You folks still there? Hope you're all well and happy. So glad to see you again!!!
Aloha Patrick! Good to see you again! My schedule got a little messed up (I used to post at 8:45am every Saturday) and the last month or two I have not posted every week and not always on Saturday. We are indeed still in Hawaii but the next few videos will be from Minnesota as we just went there for 3 weeks and I had the opportunity to film some videos using my in-laws' units. 😄 Everything is well and happy for us on the island! I hope you and family are doing great as well! Stay cool out there 😎
@3:15 your advise it perfect for the humidifier featured in this video (Aprilaire 700), it should be mentioned though that this model is not a bypass humidifier so simply turning down/off the humidistat is adequate... however... Most humidifiers I encounter are bypass humidifiers. On a bypass humidifier we also want to close the bypass duct during the summer season if you operate AC in addition to turning down the humidistat. Failure to close the bypass duct could contribute to a high temp split and freezing of the evaporator coil. Humidifiers like this one (Aprilaire 700) have a built in fan, humidifiers without a built in fan will likely have a bypass duct that should be closed/blocked during AC usage. Great advise though as usual, thanks!
Intake and discharge should be 10 feet apart. Other wise HRV will be recirculating same bad air.
Thank you for the info! I was not aware of that. I see many, many intakes and exhausts that close to each other.
Yeah, its so close that the exhaust air is going back through the intake. Home inspectors say at least 6 feet apart, 3 feet for other vents. Also better if the exhaust has a damper.
My intake and exhaust are far apart
Specs shows at least 36” away but yea this looks like 12”
10 ft away from gas appliance exhaust.
6ft is recommend
3ft is ok.
Wow. Very informative videos. I’m originally from California and now live In Minnesota so all this is been so foreign but your videos make sense. Do you have a video on what a dehumidistat is for? Going to turn off exchanger right now lol
Great tips 👍👍
Thanks Harry! Appreciate you stopping by! 😎
Hey Jay,
Great videos! Curious about this one though. Don’t ERVs exchange some of the moisture w the outgoing exhausted air. Turning them off seems to defeat the point of installing them to pump fresh air into the house. Turning off an HRV makes sense to reduce humidity levels in the home.
Good job. My advice to you all - if u wipe the hoods on the outside of the house with viniger u can paint them to match ur siding.
Thank you! We appreciate the tip!
So I learned something new: I was running my Air Exchanger during the summer.
Great info Jay ... Dang them math teasers ... Lol ... Aloha my friend ...
Aloha Eddy! Glad to hear you enjoyed the math teaser 😄 If you were like me, you probably were not even close. 😂
Have a great weekend!!
Hello my number one good buddy 👍👌👊🤙🤟 jay. Good to see you again my friend 🙏 well my Dr had got me an appointment the twenty fourth of this month I'm dreading it buddy I was up all night last night with arnold he was in a lot of pain but he is doing pretty good today and I'm very thankful for this..I was hoping to get in sooner but they didn't have any cancellations... BTW happy father's day tomorrow my good buddy 👍 I pray you all are doing well and safe and I always have you all in my prayers 🙏 God bless you and your family jay me and Arnold love you all
Hey David!! Good to see you made it to the comments section 😄 I get concerned if you don't show up for a while. Oh man, so Arnold's health is still going up and down.. Which I suppose is better than only down... I'm happy to hear today was a good day for him. Hopefully both of you will be able to get some good sleep tonight! It's already the 20th so the doctor's appointment is right around the corner.. And thank you David! My son has been growing up and getting smarter at a scary fast pace! My wife and I celebrated our 11 year anniversary today too, time flies! We came back to Minnesota for her brother's wedding and I was able to make some MN videos while I was here. Thank you for the kind thoughts and prayers David, you are a good man! God bless you and Arnold as well! Stay safe and may your health see more ups than downs! Aloha from Minnesota! (will be going back to Hawaii in 2 days)
@@WordofAdviceTV I sure wish I could meet you all that would be like heaven on earth to finally meet you all but I'm not in good shape to travel I always get someone to take me if I have to go very far because my legs go numb after a while from just sitting very long it has to do with my back troubles but I tell you what buddy 👍 I'm scared sick about arnold because he is like my own kid and I know something is going to be bad wrong when the results come back I just feel it I can tell I hope and pray 🙏 not he is all I have left he is having a episode now so I am fixing him some medicine as we speak.. thanks Jay you are a very good man and friend to me you have always had just the right thing to say to me and I thank you for your help being my friend through this very uncertain times..
@David McKinney Oh man, sorry to hear about Arnold David.. I can't say I know how you feel since I have been fortunate enough to not go through something like that. I really hope things will not be as bad as you feel they might be. May the Lord bless you with peace and wisdom during your uncertain times. We will pray for you and Arnold, don't forget to take care of yourself during this time as well...
@@WordofAdviceTV I love dogs better than anything but they have a very short life span and it's very hard to have to give them up and if you try to keep them going it's very expensive I have spent several thousand dollars on bigfoot over the last couple of years and untelling how much I will have to spend on Arnold I don't care about the money though it's not about it is why I mentioned it but yeah it's awfully bad to have to let them go I wish everyone could have the experience I have had with my two dogs Bigfoot and Arnold but definitely not the being sick and emotional part of it so I say that they are probably not for everyone I guess it depends on the person but believe you me they are a true blessing I put bigfoot away like a person I ordered him a casket from the Batesville casket company and a very heavy duty steel burial vault it's supposed to be watertight for a hundred years I hope so anyway
@@davidmckinney6577 Oh I believe it! My sister has 3 cats that she really loves and she spends a lot of money on them too. (Especially in special cases like when one of them got hit by a car and needed surgery and all) Things are only as valuable as we the value we attach to them right? For many people the value of their pets are higher than the value of money. You are a kind soul David, I hope you will be rewarded with Arnold getting better.. God bless and Aloha from Hawaii!

Welcome!! Good to have you with us 😄 Have a great weekend Timothy!
@@WordofAdviceTV thank you
@@WordofAdviceTV you also have a great weekend
I think that might be my problem. Live in a semi detached and the humidity levels on the VanEE hrv is over 60% which I think is too high. Maybe I should just turn it off even though the builder says to keep the fan always running.
I wanted to ask you if you may know why a 12.5 ton commercial unit. Brand new. The fan seems to pull so hard the water isn’t draining. The drain pipe is in a vacuum?
Hey jay once again greatly appreciated info.. my question to you is, how do i know if I need an Air to Air exchanger? 🤔 and where is the duct work connected to?
Most houses are just fine without it. If a house has a stale musty smell to it, then it may benefit from an air to air exchanger. I talk a little bit more about that in the first few minutes of this videos: czcams.com/video/vLksdXMFY4g/video.html
The ducts are not always connected or routed to the same place. It varies from house to house but if you search "air to air exchanger ducts" on google images, you will see some nice diagrams where it shows how some of them are routed. It's nice to be able to see it in a cutaway type of view.
Do you have a previous video explaining what an HRV does? This is not code in every state like you state. This isn't a thing in Kansas and I've done installs on new construction quite a bit in the last year. Thanks, man.
Changing you filter monthly does not prevent you motor from burning out as your motor draws less current with a clogged filter, but a clean filter does protect your heat exchanger from overheating and premature failure. HVAC Electricity 101
I live in Minnesota when should I run my air exchanger I live in a townhouse 1600 square feet. I have heard two different answers I need some confirmation
Please if you get a chance, a video on two stage H/C systems and the role of variable fan system
If I get the opportunity later, I will see what I can do. Thank you for the video suggestion! So far the only video I have like that is on how a 2 stage furnace works: czcams.com/video/iLRHofwyxm4/video.html
As a hvac tech we fix them alot. Hear the same excuses from homeowners. Yes it has filters you have to change/clean, no its not maintenance free. Also there is NO REASON to touch your humidifer at all during the summer. The way they are wired to the control board of your furance it absolutely can not run during the AC season unless you put your heat on. Only thing you touch is to close off the bypass damper to summer if you have that style. The pads need replaced at min every two years
Thank you for the clarification Zack! Much appreciated!
...assumed that the humidifier was wired properly.
@@Jon-hx7pe If a person can read the directions correctly they are wired so the only way it will receive power is during a call for heat. Some models do offer a option to operate without running heat but are rare do to the costs of said systems. Not saying I have never seen them wired wrong but under correct and normal instructions they won't run.
Question: I have a 1991 Lifebreath air exchanger which has aluminum mesh filters. After 30 years, it's time to replace them. Can I replace them with spongy, foamy types? Also, where can I get them? Thank you in advance for the help and insight.
I need to label mine
Summers vary. In some states summers are dry, and in others humid. My duct butterfly valve is labeled, summer/winter. Wouldn't it make more sense to label these as dehumidifying on/off? It's the middle of July. Today Is one of those in-between muggie days, cool, but the humidity is over 90%. Should my valve be set to summer or winter? I try to reason this out: In a humid summer you want the dehumidifier on. But your video said that it should be off in the summer, so I'm confused.
Me too
He said Humidifier should be turned off in summer, not Dehumidifier.
I set the dehumidistat on my HRV to 45% humidity. It was running. The indoor humidity is less than 40%, but the HRV doesn’t stop. It just kept on running, why? The only way it seems to running normally was when i set the dehumidistat to off and set the HRV to run at 20/40. Only then it will run 20 mins and off 40 mins.
It says "Intake" in sharpie in the left vent. Classic original mislabel
Oh is that what it said? I didn't even notice that 😄 Good eye you have there!
Aren’t thos two vents too close together, shouldn’t they be 3’ apart?
Nice Jay 👍😊
(Joke coming)
Thank you Mr. Classic! Always good to see you.
Today all of a sudden my AC (and heat and even just the fan) started to short cycle. The error on Honeywell zone board said "AC Voltage Insufficient". The zone board would lose power for about 15 seconds and start up again, and AC will turn on for about a minute and then the same thing. What do I do? Do you have a video on that, please? We are expecting temp to be in 90s for next week.
I replaced the transformer which seems to have fixed the issue.
3:40 why are they so close to each other? Isn’t bad air going back in when it comes out ? 😂
The vent should have a flap so when intake kicks in its not sucking air thru it during winter months otherwise youl never get ride of your humidity plus it's shooting your hot air out your gas bill will sky rocket but they know that thats why they play dumb and not show you that
Hey Jay!!! My compressor had finally locked up and of course it happened right before the worst heat wave Seattle has ever had. Its 101 right now and tomorrow will be 10-15 higher! Couple questions. Can I install a new 3 ton condenser using a 2.5 ton coil? Also, instead of brazing the copper lines when reinstalling the condenser is it ok to crimp? What do you recommend? Thanks!
3 ton condenser on a 2.5 ton coil could work as it's usually ok to be +/- 0.5 ton on the coil, does your air handler produce enough cfm for 3 tons though? Airflow is critical and with a smaller coil freezing will be inevitable if airflow is lacking. You need 1200 cfm for 3 tons, don't forget to factor static pressure also... Crimping or brazing are both acceptable is done correctly, depends on your experience/comfort level. also when you say locked up, have you tried a hard start kit/capacitor? for less than $100 they REALLY increase the torque at the rotor during start up, might get another season or two out of it if the hard start cap gets it going again. May be worth trying...
My man has the knowledge of 30 yr veteran and looks 21
vents need to be 10ft apart and also if your house uses the air exchanger to vent your bathroom moisture, turning it off will cause major problems.
Valid point for distance between intake and exhaust (insufficient in this video).
An even better point is if one or more bathroom fan are connected to ERV, they won't work if ERV is unplugged.
Jay.....you say air exchangers should be turned off in the summer. So I'm assuming people who live in warm climates all year round do not need to use air exchangers. They use the AC on hot days and open their windows when AC is not being used.
You didn't respond sir
If you have air to air exchanger do you even need a humidifier
Are you back living on the mainland? MN?
You are half right :) I am indeed back in MN but we are only visiting for a couple weeks (wife's brother had a wedding). I was able to film a few videos here so I feel like it was a productive trip! Will be going back to Hawaii on Monday.
@@WordofAdviceTV Tnx so much for responding. Have a safe flight back home.
@SZretired No no, thank YOU for watching and leaving a comment! You've been a frequent visitor of my channel and I appreciate that. Thank you for the well wishes, my wife is packing up our bags as I type 😄 Flying out tomorrow morning.
A local priest and deacon stood by the side of the road holding a
sign that said "the end is near, turn yourself around before it's too late". They held the sign up to each driver going by. Leave us alone you religious nuts, yelled
a man driving by. From around the corner they heard a big splash.
The deacon said to the priest, Do you thing we should change the sign to just say " Bridge is out" ?....
LMAO
Hahaha I love it! Thank you! I will be adding this one to the list. Along with the 3 elderly sisters 😄
YOU ALREADY KNOW TOO MUCH, Are you planning to get contractor liscence soon? ? How long have you been in the field?

Hi Jay I have some questions for you. Do you have an email I can email you God Bless 🙏🏻
Edit: Sorry, I have a bad sense of humor.
I pre-burn those motors out to let the magic smoke out after installation while all the windows are still open. This way the owner who forgets to change filters will never have to worry about them burning out and smoking up the house in winter when everything is closed up.
The filters stay clean forever without cleaning once the magic smoke has been let out of the motors.
When will those stupid manufacturers learn to make units without the magic smoke, all bottled up? Pre-releasing it adds an hour to labor bill, homeowners pay the price.
🤔
Seems like the days of "KISS"are over ???

It sure does seem like we are headed in the opposite direction... Some of these new units are loaded with way too many un-needed trinkets.
In and out are too close
You're wrong. This is terrible advice. You need to air exchanger to run all year to remove CO2. In my office with the window and door closed I go from 500 ppm of CO2 to 900 CO2 in about 15 minutes. At 900 ppm of CO2 I'm tired. I feel like I need a nap. I can't mentally work at the capacity I need to.
