This was a really awesome video. Kinda helped me understand the process for choosing the right capacity. I have one question tho. How do you know which brand or model of equipments to use. Do you get these specified by your architect/builder/client or do you have some method behind it. Plus can I get the manual s speed sheed aswell as the manufacturer's data for practice. I don't know where you sourced these from
If your outdoor air temp is 90 degrees, why do you use the 105 degree data instead of 85? seems like it would make more sense to choose data that are above and below your actual design temp instead of both that are above. Or it just doesn't make a difference?
I use CoolCalc for loads, Sketchup for modeling duct design, then manual-s & d speedsheets. Basically all the same workflows that are documented on this channel is currently what I still use.
Yes, I do like this bag. I had to pay to have it shipped from the UK as they're not available in the US. The back pocket does not fit my larger iPad very well (but I have the magic keyboard attached), it would fit an iPad-mini well. I think a veto TPXL is probably better for us in the states because of the shipping costs / hassle to get them over to the states.
Cool-Calc is Manual-J 8 compliant, so it uses values that are found in that edition of Manual-J. I'm not sure that it goes up to R-60 for attics, but R-40 on walls may be able to be accomplished when modeling with exterior insulation + cavity insulation.
@@mhoush I believe Wrightsoft allows you to enter actual R and U values and is also MJ-8 compliant. Frankly, in this age it'd be silly to not allow it.
This from Cool Calc: You have to change the wall type in order to get higher r-value options. For example, a 2x4 wall is going to be limited to R-15 due to the amount of insulation you can fit in a 3.5" cavity, but if you change it to a 2x6 wall, it allows up to r-21. Then you can add additional board insulation on top of that to achieve higher r-values. Getting the r-value close is more important than matching the exact construction type. I believe the highest wall r-value in the Manual J tables is achieved by selecting "Insulated concrete forms", which will get you to about r-36. We allow custom u-values to be entered for windows so that should not be a problem. If you select "ceiling under attic" you can enter r-values up to R-56. The R-33 limit you were seeing was probably on a vaulted open beam ceiling. Our next release will allow custom r-values to be entered, but you will most likely need to make a manual adjustment on your report to account for the difference between R-36 and R-42 walls as well as R-56 to R-62 ceilings. I think you will find that when homes become that efficient the cooling/heating loads are so low that the r-value adjustments are going to be minimal. We can assist with those adjustments if you send us your final report. Best Regards Bill
Thank you for this video. I am trying to get a load calculation for a tricky house, very fancy one and the results look a little bit scary to me. I went through every single detail. I took measurements of the windows, doors, ceiling heights, Floor dimensions, etc and I am still very hesitant about the results. I tried to call them to ask them questions, but they direct you to the email and that, to me, is bad, because there should be more customer support to answer some questions in order to familiarize with the software. When they say HVAC System, are they referring to the system already installed or the one that you are going to install?
I have not had great success with their tech-support (they essentially ignore me), however I'm guessing because they're a software company they may not know / understand all the details of Manual-J and so they probably try to field questions as some of them may be better directed to people / trainers who have a better understanding of Manual-J... It is not uncommon when used to using rules of thumbs for sizing vs. using Manual-J to be uncomfortable with results. Sorry for the delayed reply. I did not see your comment earlier.
Mike, did you ever get an answer as to what needs to be put into the Wind velocity winter/summer (MPH) field? Or where that data is found/gathered? Thanks for the video's man.
nice👍🏼 I carry a magnetic parts bowl also. I recently switches from the metal one like you have to the collapsible craftsmen silicon magnetic tray CMMT98343. I like it because its lighter and flexes when I close my over stuffed bag.
I like the magnet idea. I got the Klein tradesman master (48 pocket) tool backpack w/removable caddy. That thing is amazing. Lol, the family gets pissed at me every time I say, “my tool bag is the only thing in my life that has never let me down”🤣😂…. Except I don’t like how they designed the caddy. I’ve been looking for ways to do the same thing. I wanna customize the caddy in that bag. Anyone know who would sew together really thick plastic??? I wanna remove one of the inner walls from one of the old Klein backpacks by pulling out all the stitching. Taking that and doing the same to the caddy. Remove the threading. Then take the liner from the old bag, and replace one of the sides of the caddy. Anyone got any ideas??? 🤷♂️If what I said makes any sense…
Compared to what we used to carry 30 or 40 years ago we could just about carry everything in our oversize pockets in a pair of Charhart construction pants or overalls.
@@mhoush I always like too much I have the same problem. My better half always tells me I spend too much on tools that I spend more on tools and training every year than many peoples yearly wage
Just stripped one out 3 days ago, upset I didn’t know what works best. Gas valves of Dayton thank you sir! Ordering 2 now, one for myself and one for my Dad.
I thought the same when I bought the coin drivers, it was one of the reasons I purchased but was not as good as I thought, so I went down this rabbit hole.
Thank you for the video. My son and I are learning to use sketch up. I liked your videos with some little tips and tricks on how to apply sketch up if you can do some more of those would be very helpful. Since sketch up is rather easy and they still have a free version for the guys who are just now getting into 2-D or 3-D graphics.
@@mhoush we’re having problems converting sketch up to a PDF to take it to a print shop and blow up the scale to 24“ x 30“ it comes out all pixelated you cannot read the writing and the measurements. We’re not having trouble with the actual conversion part making a PDF. It’s the resolution making the writing blurry. If you have a simple cure for this problem would be greatly appreciated thank you very much. It must be in the settings a simple little fix but have been unable to come across it ourselves.
You said that you found the plans online. Is that a customers plans or it is random plan? If it is customers plans I really would like to learn how to get it.
This was an architecture print I found online... I typically only get prints for new construction or large remodels, you can check out some apps that allow you to build a blueprint style document w/ field measurements. I've been playing with one called Room Scan also have used Magic Plan (not sure how the work on Android).
I mean without more details on your project it's hard to say. If the inputs are correct, then I do trust the loads that come out of CoolCalc, if that's the question.
Bought the testo 1st gen probes a few years back for use in F&B refrigeration at my facility. When the job frowned on tools going in and out the door every day, convinced them to purchase the FP probes. During coronacation had the time to play with them all using MQ on some sidework residential calls. Love that they both play well together and get get those extra readings at the same time. Met you briefly at Kalos in February, shocked that you have so few followers! Hope to see more content when you have the time to create. Thanks.
Definitely plan to implement a proper radius return elbow on my parents upflow Furnace as part of replacement...even with lower airflows I'm sure there're numerous benefits to a return box as well (for lack of a better term)
