This page was designed by me not just as a recycle bin for old quizzes, but as a training tool for anyone who considers himself as a pro or hoping to become one in near future. So, now, when I’ve got 12 quizzes on this page and one on the parent page it’s time to unveil my idea.
Maybe I’m wrong but I’m thinking: - if you have found this page on my website you are serious about profession of the HVAC installer. And maybe you would like to have a little test to find out how really good you are!
So, here is my vision how it can works:
You will send all 13 answers on my e-mail address, and I will evaluate the score for each one. So far you can get from 13 to 65 points, and if you get 65 points you are the winner and I will send my congratulations to you and you can consider yourself as a great pro in this field!
If you get less then 65 points I will post your answers with the smileys attached to them so you can understand how close you were to the right answer.
If some of your answers are right I won’t post them at all.
If you think that you know the right answer after you see on this page that one of your’s is wrong you can submit another one, but not before I will publish the next quiz!
Also, some of you have a lot of experience and probably have own tips and tricks, so you can share it with us in a form of quiz which I will publish on the “How Did I Do It Quiz” page.
But some of you may need the answer for any of the quizzes right now because it can help you in your every day work. So, for the price of only  1.99 I can e-mail you the answer!
I know that this page has been visited by professional installers. But no one so far expressed any desire to purchase anything, asked any questions or submitted any answers for the quizzes on this page. In my surprise I never sell anything on this page! Can anyone to explain why?
I know from my experience that tips and tricks represented on this and “How Did I Do It Quiz” pages aren’t much known among HVAC installers. There are no books available about ductwork installation and people don’t stay for too long in this trade because physically it’s very difficult. It’s why if you are an apprentice you have guys around you with little or no experience at all.
So, if you are an apprentice and decided to stay in this trade for a long period of time you have to know everything what I have here, on this page. It will make you much more valuable for the company you are working for. It will reduce risk that you will be laid off if your company doesn’t have enough work for everybody.
The price for all answers so far less then $24 – you barely can buy good snips for this amount of money. But I suggest you to do following:
Copy all the quizzes from this page and paste them in the Microsoft Word, print it out and show it to your coworker who actually training you. Ask him if he thinking you may need this kind of knowledge in your work. Let him answer the questions represented in the quizzes and email it to me. I will evaluate his knowledge and understanding and tell you if you need anything to purchase from me. If you do we can negotiate a wholesale price for the tips and trick you are really needed.
Spiral Duct Quiz
 Our company is doing light commercial as well, so I also have an expertise in this field as well.
What you see on the picture is a 16” spiral duct 18’ long with four register boxes cut in.
The questions for this quiz are:
1. What did I do to put all four register boxes strictly in line?
2. How did I calculated the distance between them, so they was set so perfectly even.
3. Why did I seal with the duct sealer all around the register boxes and every connection of the pipes?
All three questions above aren’t difficult at all, but only if you are right from the school! Otherwise, nobody even in my trade meet this kind of issues too often: especially first two. So, if you have this kind of issue ahead of you I can help. Price for my help is 1.99.
Leaking PVC Pipe Quiz
 Unfortunately it’s doesn’t matter how good you use a cleaner and PVC cement, from time to time those pipes are leaking. The last week my boss sent me to do just that: to fix a leak in the PVC exhaust pipe.
When I arrived at the house I found a new guy hopelessly trying to fix the problem for at least an hour. He was applying layer after layer of the PVC cement on a leaking spot but it obviously didn’t work. When he saw me he said that he needs two couplings, two pieces of pipes and a new elbow to replace the leaking one. I said no, this is not how we fix such minor problems in our company. Nowadays it’s easier to fire your sorry a.. then spend time and materials for nothing! So I’ve fixed the leak in less then 3 minutes!
How did I do it?
 The problem which was resolved by me in the quiz above can occur in any house at any time. If you want to save money and time instead of calling for HVAC tech or plumber (60 only for a knock at the door) you can fix it very easy by yourself. With the tools which you already have and materials you can buy you can fix it for the less than 10. So, send me an e-mail with explanation of your issue and a picture of the leaking spot and if I can help you the price for my help will be only 1.99.
Heat Runs in Floor Trusses Quiz
The other day I was running 6” heat runs in the floor trusses and it was pretty difficult job. The distance between the trusses is 8” – 8 ½” and trusses themselves made from 2 by 4 so they 3 ½” wide. But anyway I’ve managed to run 30” long pieces of the pipes!
How did I do it?
For this one I’m actually received the most answers none of them was right! But here is one little trick which helps me to make the job done! So, for only 1.99 I can explain how to do that.
7” Duct Fabrication Quiz
 
Bundle of 6" pipes 7" pipe 4' long
Recently my boss sent me to do a minor repair in Ann Arbor. He called on my telephone and said that 6” round duct in a house we have finished two month ago is smashed and I have to replaced it. He asked if I have any materials, I checked it out and found a bundle of 6” pipes in my truck. One hour later and 45 miles away from any supply house I found out that actually it was 7” pipe smashed! I came back to my truck and found a piece of 7" pipe 4’ long, but I was need a five footer! After using several words mostly four letters long toward the superintendent who couldn’t distinguish between 6” and 7” pipes I made 15” long piece of 7” pipe from 6” pipe in less then a minute!
How did I do it?
An answer for this quiz would be very useful for DIY-er and also for anyone working in the ductwork installation field. A simple knowledge how to reduce or increase size of the duct can save some time and finish job on time! So, for only 1.99 I can explain how to do that.
Broken Elbow Quiz
Last week I was working in the basement doing heat runs, when I found out that I’m out of 6” elbows. After searching in boxes I found a couple of them but they were broken. It was what I need! In matter of seconds I fixed them and finished the job!
How did I do it?
Fix a broken elbow is a very easy task! But nobody knows how to do it! Why? Because nobody cares! Tin knocker will send it to the shop or just throw it away. But if you are a self-employed contractor you probably don’t have too much time to waste! So, for only1.99 I can explain how to fix a broken elbow!
Offset Calculation Quiz
Some of the HVAC installers who are working in this field know the formula:
 M = O x W : L
Where: M – How much you have to miter a duct.
O – How much you want to offset a duct.
W – Width of a duct.
L – Length of the duct.
But I believe almost none of them know how to calculate M if you are dealing with the full length of a duct as you see it on a picture. The problem is: when you cut M from the duct it becomes shorter and it doesn’t reach the point indicated by figure O.
In order to figure it out you are not supposed to be a super tin knocker, anyone who had C - for geometry and higher able to solve this problem. I’ve resolved it in 5 minutes!
How did I do it?
Answer for this question appears to be a very difficult! I didn’t receive any answers at all. You can do research on the web as I did and found very strange explanation with tons of geometry which even I with my university diploma couldn’t understand! So, for only 1.99 I can explain how to do that.
Jumper Calculation Quiz
 What you can see on the picture is a “jumper”. When I ran a pipe from the joist space on the right to the left, I even haven’t a pipe there (in the joist space on the left). But anyway I have managed to make a right measurement and placed a pipe in the middle of the joist space.
How did I do it?
For a reason unknown to me a jumper always was the most difficult part of the trade, check for example this one out, and from my experience I know that not too many tin knockers know how to calculate a jumper in the right way. So, for only 1.99 I can explain how to do that.
6” Pipe Quiz
 Recently I was working in the basement, doing heat runs, and probably I was thinking too much how to improve my website! In the result I put together too many six inch pipes – nine of them. When the job was done to my surprise I discovered nine extra pipes all over the basement. I said to myself – it’s not a big deal! In less then a minute I took them all apart and put back in a bundle!
How did I do it?
This one is funny! Recently on one of the Forum websites one of the visitors asked how to unsnap a pipe. Any of you should read the answers, one of the EXPERTS  even recommended to use a grinder to cut a pipe on pieces, another suggested just throw them away and buy some new ones for only 7 a piece!!! But you will be just astonished how incredibly easy actually is to unsnap a pipe! So, for only 1.99 I can explain how to do that.
Pipe Length Calculation Quiz
As you probably know in order to connect two pipes or fittings together all pipes and fittings must be crimped. The length of the crimp is 1 ½”. As you see on the picture the pipe is situated between two elbows. But let's say the distance between those elbows were longer then you see on the picture, and it would be 92 ½”. So how long should be additional piece of pipe if the first one has a standard length of 60”. I resolved this issue just in 5 minutes!
How Did I Do It?
Answer for this quiz has its value mostly for the professional installers. If you make a measurement and the distance is bigger then the length of one pipe (60”, 30”), some of you don’t know what to do next! So, for only 1.99 I can explain how to do that.
Dent Elimination Quiz
 What you see on the picture is a dent on the flat 90*. I wouldn’t say it’s a big deal, but in some applications this dent can make a popping noise. Also if you leave a duct with this kind of damage on it, it’s looks sloppy and unprofessional. So I fixed it in less than 1 minute.
How Did I Do It?
I’ve received this email some time ago: “I had my mom (the only one small enough) get behind my furnace to help me run a wire. In the process she had to squeeze against the return. I believe she may have popped it in. Now, when it starts and finishes its cycle the return pops.” If you are having this kind of help from your relatives or maybe you neighbor 7’6” hit your duct with his head you may need the answer for the quiz.
So, if you have this kind of issue in front of you I can help. Price for my help is1.99.
Blocker Installation Quiz
 It’s always fun to talk to a new guy when he got hired in your company! Usually he starts to tell the story how incredibly good he is and how fast he can do any kind of ductwork installation while, let’s say, doing a piece work. What he expecting from you is a loud WOW!!! But I always keep “wows” as a last resort until actual job is done.
This time around when a newbie started to do the blockers installation he spent 6 minutes for each. I looked at him and said that during this time I could’ve 3 blockers get done and I’ve showed him the technique. So, now I was getting a big WOW!!!
So, for only  1.99 I can explain how to do that. See PayPal button below.
Reducer Quiz
Yesterday I was working in old commercial building replacing old heat runs. Almost all of them were 9” round pipes and fittings – odd balls, and my task was to replace them with 8” fittings, pipes and diffusers. At the same time my boss told me that I have to save as much old stuff as possible in order to help him to save money. I‘ve been told that he will buy some 9” to 8” reducers which will terminate every 9” heat run, I able to save, for the 8” flax. When it comes to the time to give me those reducers my boss found out that there are no such things available at all! There wasn’t any supply house in entire Detroit aria caring things like this!
 He was lucky enough to find a few 9” round caps and 8” collars at the shop to make the reducers, but for the rest of the 9” heat runs he come up with another bright idea: replace them with 8” collars, pipes and fittings! As a good employee I’ve said – all right, but for myself I’ve said – no way!
I’m not crazy to take all the 9” take offs off, patch the holes, cut a 8’ collars in and run the pipes with fittings when it’s all already done and I need just a few lousy reducers! Luckily I found some 9” pipes and made the reducers in no time!
How Did I Do It?
If you a self - employed contructor or thinking about ductwork installation seriously you may need to know how to make field made reducer (I’m actually know two ways of making them). At first try to find the right answer or for the price of only 1.99 I can explain how to do it.
