HVACR VIDEOS HOUSE PROJECT PART 7

[@lobehold2263]

This is the thing with high efficiency units. Do what you did, and you’ll get your money’s worth. Unfortunately most do not do what you did

[@brianjones5935]

dude does not fuck around when it comes to the family. i love it

[@ChaseCares]

This was a very informative video series, I really enjoyed seeing how well the work was completed and why you did certain things. Any updates?

Me doing the side-eye as you mention your couch hippo of a dog being 80lbs, while my couch hippo is 115 lbs lol. I should take him for more walks too

[@coreycook2097]

Carrier infinity used to be a nice system like yours but lately I have had so many problems out of the box with these systems. Not sure what’s going on with carrier but the quality control must have taken a hit.

[@isaacwall9514]

Have you considered an ERV for fresh air? Carrier makes one that connects to the infinity system. I have that in my house and it works great. Getting the exhaust air from the bathrooms, eliminated the need for noisy exhaust fans.

[@HVACRVIDEOS]

Yeah I am probably gonna install an erv but I haven’t decided which one yet

[@julesc.9449]

You nailed the balancing method perfectly! Amazing! For a fixed duct design (as in no VAV's changing the restriction of different paths), I prefer calling the method "proportioning" rather than "balancing". Getting the right proportion of air in each room percentage-wise like you did while keeping the most restricted path fully open to reduce static is the way to do it. BTW, in commercial balancing, the job is considered balanced when within +/-10% of design. Also, VAV controllers usually control airflow with a deadband of +/- 5% of maximum design airflow to prevent hunting. As such, your percentage discrepancy numbers are terrific! I agree with you on communicating systems not being nearly as configurable as what the hardware has the potential to do. Been doing commercial HVAC controls for almost 10 years including balancing, programming, installing, etc. Your channel is the most on-depth on YT when it comes to practical application of buolding science. Thank you so much for your high quality work and entertainment!

[@julesc.9449]

Oh, and as for bringing in fresh air into the house, are you considering an HRV/ERV? I could see you needing an ERV to conserve humidity inside the house in your dry climate but if exhausting bathroom air, you might over humidify with a tight house. An HRV might be a better fit then. You could have it ducted such that the exhaust is being pulled from the bathrooms and the fresh air gets pulled into the return of the air handler. On the control side, HRV/ERV can usually come with a timer switch for bathrooms to force maximum ventilation. As for air quality control, you'd have to check what your future IAQ sensor has in terms of auxiliary contacts and programming, what the Infinity air handler board can do and what types of main HRV/ERV controller are available for IAQ control. You'll have to do some reading to determine your preferred sequence of operation available from those different options. Of course, you'd have to call for the air handler fan to run when the HRV runs unless you duct the supply of the HRV directly to dedicated diffusers. Building pressure could be maintain that way when running the bathroom exhaust. And while less of an issue in your climate, make sure you can configure the HRV with exhaust only defrost and not recirculation. You wouldn't want bad smells throughout the house!

[@HVACRVIDEOS]

Yes I am looking into the erv/hrv route trying to decide how to configure it. I will likely use Haven air quality monitor to trigger some sort of action based on building conditions….. funny thing is all this work and my wife and I are already talking about moving in 4 years when my youngest finishes High School but if anything all this work just keeps me busy in the mean time

[@ericlederman3516]

We're making the move to IE, moving into my grandmother's old 74yr old house. Entire house needs a repipe. Definitely not a complaint! And of course I'm the one who's tasked for the job... Who else? However, I do miss the ease of commercial buildings vs residential though.

[@Mikecianfrocco]

Amazing video!!!!! The guy who did your manual Jan duct design must be so proud !!!!!

[@Guillotines_For_Globalists]

I've read that you can simply bend the stamped grille louvers to be more flat to increase airflow and decrease the noise.

[@timcat1004]

That Infinity t-stat is super sensitive to leakage in the wall cavity. I have one. It was over and under shooting depending on the way the wind was blowing. Seal the wire hole behind it.

[@MariosACandRefrigeration]

The most efficient way,is to install the returns above the door,adding return ducts adds heat.2 cents,also don't forget to cap the gas valve.thanks for sharing.

[@Byron88]

Its more efficient but its not ideal because of sound. doing an acoustically lined and exterior insulated transfer duct through the ceiling is better to dampen sound transfer from one area to another

[@MariosACandRefrigeration]

most homes have the return under the door,i have never had a noise complaint,but i have had a problem ,the house going negative for not enough return.@@Byron88

[@lillian6023]

Those are your supervisors! And the only thing I miss about doing retrofit jobs.

[@flyinghigh5531]

It’s not just me, your shut off has no cap after the valve, I left mine like that for long time too 😂 if we leave a job site it has to have it, but our own home is like ehh

[@HVACRVIDEOS]

Exactly, I will put one on it eventually

[@Metalcastr]

The thermostat at 12:16, I have the same one (Carrier Infinity Series B), it doesn't like powering back on after a short power outage. I have to shut power off to the furnace for 5+ minutes to power it back on. Anything shorter and it won't power on. It was always like that. I've tried updating the firmware via SD card (WiFi says something like firmware update not available), but it's stuck on 3.40. Maybe the latest release will unstick it.

[@nickwalston1322]

I do this for a living also. More residential. I was waiting for this. Your videos are informative. I consider myself really good at this trade in south tx. But you can always learn. You have taught me sir more about being thorough

[@nickwalston1322]

Do you like the carrier communicating system. We do Lennox and trane only when it comes to high dollar equipment

[@nickwalston1322]

Nevermind I finished your video

[@joshoneill2584]

Add dampers to the collars to adjust the airflow.

[@colinstu]

Wow that's quiet. Very nice.

[@ilickspam]

great series. thanks for sharing. i can't wait to see the erv install.

[@PATRICK-zj9xb]

Hi Chris, what an impressive job! Looking forward to more in this series. Keep it going!

[@louiebencriscutto9234]

In some of videos you’ve talked about being bored at times and looking for new ideas of your KZbin channel could turn into. You ever think about turning your website into a forum where people can ask questions and get advice from others. Then you catagorize all of videos by mod and serial number. Kind of like hvac talk but mainly focused on the videos you’ve uploaded on KZbin. I like hvac talk but I find difficult to navigate through because it covers so much. I’d be a way to basically organize all of the work you’ve done helping people learn the trade ranging from troubleshooting equipment to even where you can find manuals and info on the stuff you work on.

[@louiebencriscutto9234]

I would pay a subscription fee for something like that.

[@jasonjohnsonHVAC]

Damn Chris.....nice big back yard....im jealous of that....looks great 😊

Thanks bud I’m trying

[@combrains1]

Just curious as to the effect this project has had on your overall energy consumption for the house? Have you noticed a significant decrease now that everything is running more effeciently?

[@RichB0330]

Chris your missing out on the good weather in Chicago😬

[@HVACRVIDEOS]

I will be there is a few days to enjoy the weather

Next week isn't going to be to bad low 30s to 40s. I sent you a link to a really good pizza place not too far from the show. @@HVACRVIDEOS

[@cayden9224]

Has your office gotten hotter now that you have a smaller system? And if so what is your plan to keep it cooler in there?

[@quietone610]

That is a thick filter, wow.

[@Infowarrior-45]

If you install a uv light, don't put it within sight of that media filter. For some reason, the uv light deteriorates those media filters.

[@garysmith9772]

I retired from business as an air balance contractor and selling what’s left. Small and full sized Alnor flow hoods. Piotr, gauges etc. Half price of current.

Great work. Congrats.

[@willspeed4585]

How’d you like the powered hood? I’ve used low-flow Alnor “baby cone” hoods before, but never a powered one.

[@molabearair]

line your return under the FAU with duct board to quite the blower. Infinity is already quite.

[@nickwalston1322]

He did when he installed the unit

[@MrLaffertyheating]

Awesome job Chris! How many pascals were your rooms testing at? I checked a house I did & had 10 1/2 pascals in all the rooms. They all had almost no undercut. Even with undercuts, I think I’m going to end up needing jumper ducts to get below 3 pascals. Got me thinking about how much money is wasted in the industry with contractors chasing their tails with comfort complaints when the whole time they were pretty much oblivious to over pressurization problems. It’s not like guys installing doors have any training about the door allowing a proper return air path. Although seems like rooms just need return air grilles as well. Can’t ever get away from the fact that ducted systems are only as good as the ducts! As always you give fantastic, thorough content & anyone with a functional brain can learn tons from you! Whoever buys your house in four years gets a hell of a deal, as you solved all the invisible problems for them!! If anything they just need to change the lipstick & mascara!

[@HVACRTECH-83]

I would just cut the flange on back of return grill. Looks like you just need to cut the top flange off, i may be wrong but from the video it looks like both sides left and right will clear the framing. Then just cut a little notch out on bottom for that stud coming down the middle,or better yet cut that middle stud out, honestly if theres no reason for that stud horizontally across the top get rid of that too and then youre good. I spoke kinda soon before watching what you did but i dont see the need for all that framing in that wall. Multi tool would zip that all out flush and your grill would pop rite in flush. Oh well looks fine in the end tho😊

[@AARONJL92]

Great video! I think my master room is over pressurized as well the door will close if open a crack when the system turns on. How does a jumper duct work? Is it just a matter of cutting two grills in the ceiling with a run in between?

[@HVACRVIDEOS]

Yes but there is a specific formula to follow to get the proper pressure relief needed

[@AARONJL92]

@@HVACRVIDEOS I'm going to look into that. Thanks for the brilliant videos and info. Much appreciated.

[@cliveramsbotty6077]

would cold smoke seals around the cupboard door be enough to stop unwanted air ingress?

[@willwise9445]

Hey Chris I just bought my first house and I can already tell there is airflow issues. The supply in our bedroom seems to be way too much we have to turn the set point down to 66 for it to not be brutally hot. Do you think I should add a return or maybe a supply in the hallway to help with that?

[@flyinghigh5531]

For maybe an easy fix, you can try to shut the grill down to 50% or less in that room. See if it changes? More return always helps too!

[@johnbreland4099]

Have you tried or used Camfil green filters?

[@youjiimoji6234]

Does Carrier still have the quality it had in the mid 90s early 2 thousends the old ones just goes and goes some reparations here and there but the gas circuit and the compressor in the old ones are almost bulletproof right. How are the newer ones?

[@TylerHVAC]

Chris, I have to ask. When your children are home and your doing HVAC work and they walk by what do you think they are thinking?

[@shaunkelly9053]

Why are there two outlets next to each other? Is there a swamp cooler?

[@HVACRVIDEOS]

I’m going to use the old register as the transfer grill for the jumper ducts in each bedroom. The old registers in the living room, family room and Kitchen will all be removed and patched
