Same in German too. It seems that in medieval times cobblers were often poor people which have to sell their shoes to make a living before they could give some to their family.
Loving this video series. My dad was a contractor while I was growing up and it's very much a "the cobbler's children have no shoes" situation. I'm sure the last thing you want to do after working on AC units all day is to pull apart your own :)
I think you've started a great series. "Technicians revamping their own systems." I've been in the industry 45 years and teaching for the last 20+ and I can attest the best teacher is experience. You will learn so much as a technician by making your home system near perfect. You'll appreciate the nuances of duct fittings and what they do to airflow. You'll make changes to reduce indoor air noises and increase your quality of living. You'll be a better tech. And your family will love you even more! And if you don't wanna do that, and live with a system that is super noisy, someone needs to invent a device that turns the TV volume up when the AC comes on. :)
First off I think you are one of the top hvac channels. It takes more time and the track house guys will shot me down. I really think you should install hard pipe instead of flex. I've had years of experience in solving airflow,draft and stream problems. Trust me. A video with testing with flex then pipe would be cool. Keep up the great work.
A manual J isnt much without Manual S D T and soemtimes ZR. This is a great eye opening series for all technicians out there. I agree, I cannot find any registers I want.
Your a trip Chris, when it comes to do with your skills, But it all good, just cleaning the evaporator and condenser unit makes a big deal. Good job. No one has an idea if it's better, unless someone try's.
If the coil was that bad, I can't imagine what your blower wheel looks like. I'd like to see the airflow increase after you clean that off. Also, you must have a breach between the filter and the furnace if you're sucking in that much debris.
Agreed! That nasty ol squirrel cage is so chronically overlooked, and next to a furry coil like that, the main reason for bad airflow. Probably boost the cfm another 100 pts or so.
@@MrOlaf1972 I cleaned a mini split in a commercial kitchen recently. The blower wheel fins are a bit tighter than a big central unit, and I think airflow was at least 60& improved, maybe more. I had never seen a blower wheel so plugged up
Your house looks nice so far and with all the work you are doing on it, its going to look even nicer. Those croger registers gives the home a more modern look. I love the idea for a gaming room where the couch used to be. Maybe a video tour of the house after all the work.
Chris, I also own a 90s tract home in SoCal too. The fart fans that came with the house were awful. I changed out all four and discovered that the idiots who built my house didn’t even hook the vent line up to two of them. They were just exhausting into insulation
Good to see thought being put into the minimum viable system size for the property, and energy-neutral tactics (e.g. reducing vent size) to make things more effective. When the majority of systems are oversized by 20% or more, that really adds up over the scale of a whole city or country. Obviously it's a waste of energy, with all the problems that entails, but it also increases the peak power draw on the grid which leads to higher operational costs for everyone. There's a lot of unjust deflection from industry to individuals on the subject of waste, but individual choices around residential heating and cooling do really add up over millions of homes and years of operation.
A bit over the top with the new duct size. More modern vent covers would do the trick. Returns installed further away from the fan would make a big difference in noise. 2 ton would never work for my temperature preference. Better get the mini split for the office. That place is going to be at least 80 degrees in the heat of summer.
If you think caulking around it does much more than reducing the leakage. Fast moving air would drag air from the attic with the dust through the holes - which I would be much more concerned than leaking air.
I also find clogs at the secondary heat exchanger on 90 % furnaces in this situation where the filter lets dirty by. Got to pull the blower wheel out and look up.
Looks awesome! One thing in the kitchen - just watch blowing air right at the stove; tends to blow cooking smoke around. I had to re-do the grill in my kitchen as it blew right at my cooktop and made a mess.
Love your content! Every time I see one of your videos I either learn something new, refresh something I learned a while ago, or both. You're not weird or odd! Far from it. You're conscientious and attentive to detail. There's nothing wrong with that at all and others should pay more attention to what they do and how. If I was doing what you've shown in this video I would have CAD software open on the computer and designed and dimensioned everything, measuring the house to the nearest millimetre! I'd be calculating everything based mathematical ratios as well as practical considerations. To use something from this video, for locating the front entry room register I would have applied natural ratios so that even if was not located centrally over the doorway it would have looked 'right'. I usually have to plan and test theoretically before I create something physically. I don't do anything I can't undo unless absolutely sure about it. I also consider serviceability with projects I work on, trying to make everything as serviceable as possible with the least amount of hassle to do so. I prefer to use screws and removable or serviceable fixings rather than adhesives. For this reason I was less than impressed with the decision to spray-foam the boots rather than a solution that would make servicing or alteration easier, even though it's something that in theory should not need servicing. I suppose I am in some ways a bit extreme in my methodology. On the upside I think I have the best chance of finding fault with my ideas before spending a ton of cash on a large project followed by a ton more to fix it. I also don't know whether I'm giving too much information or too little. But then that's part of me, as someone diagnosed with autism who also happens to have HVAC as a special interest. For what it's worth, Chris, your videos help me a lot in giving my brain something to work on as well as being a great inspiration out of feeling useless and exploring avenues for a future. Many thanks.
Obviously, you are videotaping all the labor and material but what I think you should do is put a dollar figure to all these improvements to see what the total cost that you would have to charge a homeowner to make these system improvements. That would be very interesting to find out. Also, hope you will do that. Thanks.
Your not "just learning something with 20 years in", it's about putting together the things you already know into a variable. The name of that variable is "The Job".
I have a Pac-Man, Baseball, Track and field and Galaga in my house. All full size old school machines. A repairman who worked at Magic Mountain sold them to me when they removed the arcades. Push to get the games, it doesn’t suck.
If you want smaller vents for the ceiling also you should put in 6 by 6 four-way diffusers cuz they actually work really good and there's a bunch in my basement and they seem to blow a lot of are cuz they're really small
When I was in a contracting company 30 to 40 yrs ago the approach the domestic sales based sizing on standard figures (and still the same today) where commercial building were heat load calculated.
I agree with spray foaming round your boots AND caulking between the boots and drywall. Everything you are doing is how I was trying to do things when I worked in residential. It’s so hard trying to do things a new and potentially better when people just want to do what they have always done. I think you’re going to really like the performance and savings of the new unit. Question, are you adding fresh air/make up air to the system? Keep up the great work, Chris!
The house used to live in had no attics, two stories with two separate AC units and the ducts were sandwiched between the floor and the ceiling for downstairs and between the ceiling and the roof for upstairs. Its cool to see a project like this because it feels so impossible to me after living there so long I can't imagine moving registers and putting in new ducts, you'd have to rip out all the ceilings on boths floors... Directly on concrete slab so no crawlspace, that house was designed to never be repaired, the plumbing was all cast into the concrete slab and the wiring and ducts were all totally inaccessible
I think it would be cool if air conditioners had a monitor system that checked refrigerant pressures, air pressures, temperature differentials, ect. Then the monitor system could warn the home owner is something stops working correctly, so they could call an hvac guy before the system starts having major components start failing.
When you down sized, you run a heat load calc? The supply air grilles in residential are awful. Never seen such garbage. Your old SA grilles look like floor grilles. Will get minimum if any throw out of them. I always used the air guide grilles. Sidewall and ceiling. OBD as well. Little more but at least you can balance the house when your done. I use Wrightsoft on changeouts, always. Really helps. You do get to a point where you really don’t need it for duct sizing once you do enough of them for your area. It gets pretty typical. On the equipment size, it is necessary. That cfm read was off to. Looks like you gained a couple hundred cfm, but still short of 1600. Enjoyed the vid. Nice job.
Smaller registers? = Lowder air flow? Ususall, but you're variable, so. Are you going to paint to match the registers? Why have these WHITE squares stand out on your brown walls? When cutting 2X's like that it's good not to cut all the way through the 1st cut so that tail isn't thrashing around as you do the 2nd one. Get some acoustic foam to line the inside of the return plenum. There is some made just for that.
If it was possible, I would encapsulate the attic and condition it. insulate the roof, etc. with rock wool and relocate the new air handler to the attic with 1 or 2 ceiling filter grilles. It will free up that space and decouple the noise from the house. Probably a little too far along with your current design now, but I think it would be pretty nice.
My girlfriend's place got reduced from 3 ton to 2.5 ton, but the ductwork and attic air handler location really works against it. Hoping to rectify the duct situation and get better registers/fix up the existing ones. This was a retrofit as many homes have been which built before central AC was the standard, and you can see that the condenser/evap part works, but the ducting is all wrong. I suspect it's the case in thousands of retrofit homes. Many still use the in-wall units, and would probably benefit from having a few mini split heat pumps instead of a boiler/furnace and a huge retrofit central air system with messed up ducting. It's a mess!
You have to clean the blower wheel if the coil is really plugged. And put some self rinsing evap cleaner to get into dirt inside coil. Good tech but youre doing the job 50 percent. Without going through changing all those boots try upping the blower motor a fraction you will get 10 percent more air. And try taking bigger takeooffs off the branches. Then go from there
And if the coil is that dirty you need to pull the blower remove motor and board and take it to the car wash there's no way air or hand cleaning will do an adequate job.
I just avoid ducts when I can 😅 Having a gaming PC that puts out 450w of heat nearly continuously has made me appreciate the only residential friendly, zoned, VRF system... mini-splits.
It's nice to see you in the residential world. That added bonus of taking the measurements with the truflow grid was a great insight as to how it works. Although it didn't look too difficult, I'm hesitant to get one before learning more of the basics and how to correct the issues found. Would you say it's more for the experienced technician? Thank you for doing what you do! 18:50
I'm surprised you plan to use flex duct. Metal has much less friction, but elbows need to help change the direction of the air, especially in trunks. Unfortunately, you have to tape all the seams and insulated, so it takes longer. My AHJ requires mastic tape with mastic over the tape, so no tape is directly visible. Also, have you considered variable speed compressor and fan? Most of the time, the unit won't be working in the extremes, and variable speed units allow the system to run longer at a lower speed. It won't help with air mixture, but will help with reducing hot/cold cycles. If you need dehumidification, variable speed works better to dehumidify as well.
thats a lot of work to replace flow boxes. its also will be harder to go bigger if size is wrong. did you think about using blanks/ 50% fillers inside existing flow boxes? or just linear grills(faceplates) with old larger flow-boxes? i’m surprised such clogged coil was killing only 10% of airflow.
It’s better to bend “ears” out on your box so that the register screws into metal. Unless you frame wood or something around the box. If you bend “ears” it pulls tight to the drywall and makes it super easy to seal. Just got to that part👍
I'm really curious why downsizing the system makes any difference overall. You're still going to have the same heat load you need to pump to the outside. Does it matter if you run a 2T system for 40 minutes / hr vs a 4T system for 20 minutes / hour? If you're moving the same amount of heat, I expect it takes the same amount of energy (electricity) to do so in either case. Will be interesting to see what the overall outcome is when it's all done.
Why are heat ducts up high? I would think that heat ducts should be low as hot air rises and cool air (AC) ducts when you are using air conditioning would be up high as cool air sinks. Doing it this way would cause better blending and comfort.
Lol that's exactly why mechanics drive crappy cars too. So busy fixing everyone else's crap we forget about our own/don't want to deal with it anymore by the time we get home
I think it's all about efficiency. Don't let the heat penetrate in house. Optimize the air flow. Let the 2 ton unit run longer times which reduce wear on the components.
Why the reduction in system size/capacity? Never mind! I just got to the point where you state the old unit was over sized. Love the videos. Really like the way you discuss the events of your videos at the end. 👍
why not just bend or flat sheet metal the old boots down to the new size, then just patch the drywall in? seems like lots of extra work and headaches. 🤔
Basically because I'm a nut and have issues... I will discuss this on my Livestream on TH-cam this evening 9/4/23 @ 5:PM (pacific) come on over and check it out th-cam.com/users/liveOz0hgO03xGI

There’s an old Spanish proverb that translates roughly to the saying ‘the cobbler’s children have no shoes’.
in italian it's pretty similar: "the cobbler goes around with brokes shoes". 🤣

Absolutely agree on the leakage. While an individual vent is absolutely negligible, when you add up all the vents in a structure it starts adding up.
First off I think you are one of the top hvac channels.
It takes more time and the track house guys will shot me down. I really think you should install hard pipe instead of flex.

Always remember to check your filter weekly when doing construction and drywall dust will bypass your filter, have seen it in coils to many times
Weekly isn’t often enough.
it loves to get into the motor bearings also and before long they'll be nuked screeching or motor will lock up, no need to ask how I know!

Another good thing to do would have been to get the inside of the boots insulated
I'm surprised you plan to use flex duct. Metal has much less friction, but elbows need to help change the direction of the air, especially in trunks. Unfortunately, you have to tape all the seams and insulated, so it takes longer. My AHJ requires mastic tape with mastic over the tape, so no tape is directly visible.
Also, have you considered variable speed compressor and fan? Most of the time, the unit won't be working in the extremes, and variable speed units allow the system to run longer at a lower speed. It won't help with air mixture, but will help with reducing hot/cold cycles. If you need dehumidification, variable speed works better to dehumidify as well.
thats a lot of work to replace flow boxes. its also will be harder to go bigger if size is wrong. did you think about using blanks/ 50% fillers inside existing flow boxes? or just linear grills(faceplates) with old larger flow-boxes?
i’m surprised such clogged coil was killing only 10% of airflow.
There was also a broken duct on the plenum , I found it when I ripped it all out so as I cleaned the coils more air leaked into the attic
If your coil looks like that check the blower wheel
Great airflow improvement after cleaning, but did you re-install all original registers? They add lots of resistance to airflow...
She walks away then comes back with headphones 😂
Ac Pro Riverside Ca. They can get what ever you need for duct work vents & boots.
Cool video. I like seeing the progress your project......looking forward to the finished product
Are you adding an energy recovery ventilator to the system to bring in outside air? Just curious if you thought about it?
I been waiting on this vid ac guy his own home what would you recommend brand ac heat unit ?
I had pause I work nights
Is there a homeowners insurance incentive to do all of the work and energy efficiency improvement.
Is that 2 ton system going to be able to keep your office at the same temperature or is it going to get even hotter in there?
It’s better to bend “ears” out on your box so that the register screws into metal. Unless you frame wood or something around the box. If you bend “ears” it pulls tight to the drywall and makes it super easy to seal. Just got to that part👍
Bar type return & supply grills. Use duct board to line the inside of the return.
Please do a follow up and let us know how much your electric bill came down after cleaning the evap coil. Thanks for the vids!
As a home owner your like the rest of us that are slow to replace filters and clean our system
That looks like a 5-ton evaporator coil.
I'm really curious why downsizing the system makes any difference overall. You're still going to have the same heat load you need to pump to the outside. Does it matter if you run a 2T system for 40 minutes / hr vs a 4T system for 20 minutes / hour? If you're moving the same amount of heat, I expect it takes the same amount of energy (electricity) to do so in either case. Will be interesting to see what the overall outcome is when it's all done.
Avoid short cycling. Long run times reduce humidity.
would it help to add a return up high to absorb the heat in cooling rather than just having it low near the ground
Why are heat ducts up high? I would think that heat ducts should be low as hot air rises and cool air (AC) ducts when you are using air conditioning would be up high as cool air sinks. Doing it this way would cause better blending and comfort.
Tubing insulation has an optimum limit. If you put too much it will increase heat loss.
Have you tried comparing measure quick's airflow calculation with the true flow grid?
Good decision not to mess with the truss system. Walls and stuff, sure, but if it is pre-engineered do not touch it!
why is oversized equipment bad? wouldnt it cool faster and shut down?
I will discuss this on my Livestream on TH-cam this evening 9/4/23 @ 5:PM (pacific) come on over and check it out th-cam.com/users/liveOz0hgO03xGI
I can't believe it Chris, as much as you complain about people not doing PM and cleaning their coils.
QUESTION??? What are you running for a static pressure?
@12:36 You should be horsewhipped. Really and you KNOW it! LOL
Lol that's exactly why mechanics drive crappy cars too. So busy fixing everyone else's crap we forget about our own/don't want to deal with it anymore by the time we get home
How did that even happen? With the correct filter, it should stay like new for over 20 years
i love your videos, they are soo entertaining! :)
Why not install dampers to balance the system?
A clear case of "the cobbler's children go barefoot".
1:45 scared me bad, had my volume high too
I want to see the dog wearing a shower cap or hair net. Will it be full body?
I am wondering if just evapcoil cleaning could solve the problem of high electrical bills instead of going through this pain 😂
Chris, you got two dogs? i thought you only had luke the labrador i didn't know you had two dogs. And WTF did you do to that poor A coil lol.
Chris with the temperatures in California being so high, will 2 tons be enough to keep your house cool?
I think it's all about efficiency. Don't let the heat penetrate in house. Optimize the air flow. Let the 2 ton unit run longer times which reduce wear on the components.
Why the reduction in system size/capacity? Never mind! I just got to the point where you state the old unit was over sized. Love the videos. Really like the way you discuss the events of your videos at the end. 👍
why not just bend or flat sheet metal the old boots down to the new size, then just patch the drywall in? seems like lots of extra work and headaches. 🤔
Basically because I'm a nut and have issues... I will discuss this on my Livestream on TH-cam this evening 9/4/23 @ 5:PM (pacific) come on over and check it out th-cam.com/users/liveOz0hgO03xGI
boy, that HVAC/R guy needs fired for not doing maintenance! 🤣🤣
maybe you can con the wife into doing the maintenance work. lol
That's the bell cuve wit IT stuff as well, You know nothing, then you think your know everything, then you relise how mutch you don't know and become a expert.
Putting the register that high isn't going towoen that well good luck in that room.
Pro tip: Don't put your hand in a hole by the sawzall. Those are nasty ouchies. Don't ask!
