Jumper Installation 

In my experience, Jumper installation appears as the most difficult issue to study in this trade.

1. Existing Plenum Transformation Trick

Sometimes, when you’re replacing an old furnace, the existing plenum is larger than a new furnace just for 1”.

In this case you may avoid making a new plenum but unfold one of the flanges on the existing one and screw it right to the side.

However, as you can see it in the picture, the unfolded flange isn’t long enough to be fastened to the furnace jacket. No problem! I resolved this issue in 5 minutes!

2. Broken Elbow Tip

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, but they were broken. It was what I needed! In matter of seconds I fixed it and get the job done! 

How did I do it?

Fixing a broken elbow is a very easy task! But nobody knows how to do that! Why? Because nobody cares! The tin knocker will send it back to the shop or just throw them away. But if you are a self-employed contractor you probably don’t have too much time to waste! You don't need no extra trip to the freakin job! So, for the price of only $1.00 I can explain how to fix a broken elbow in no time!

3. Leaking PVC Pipe Trick 

Unfortunately it doesn’t matter how good you use a cleaner and PVC cement, but from time to time those pipes are leaking. The other 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 for at least an hour hopelessly trying to fix the problem. 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 in our company we fix such minor problems . Nowadays it’s easier to fire your sorry, stupid ass than spend time and materials for nothing! So I’ve fixed that leak in less than 3 minutes!

How did I do it?
The problem which was resolved above can occur in any house at any time. If you want to save money and time instead of calling for an HVAC tech or a plumber ($ 80.00 only for a knock at the door) you can fix it very easy by yourself. With the tools which you already have and materials that you can buy you can fix it for less than $10
So, purchase a solution to the problem just for $1.00 – do it yourself and save!

4. Heat Runs in Floor Trusses Trick

The other day I was running 6” heat runs in the floor trusses and it was a pretty difficult job. The distance between trusses was only 8” – 8 ½” and trusses themselves were made from 2 x 4 so they were 3 ½” wide. But anyway I’ve managed to run 30” long pieces of the pipes through!

How did I do it?

So, here is one little trick which helped me to make the job done! For the price of only $1.00 I can explain how it should be done!

5. 7” Duct Fabrication Trick


Bundle of 6" pipes                             7" pipe 4' long

Recently my boss sent me to do a minor repair in Ann Arbor, MI. He called on my sell phone and said that a 6” round pipe in a house that we finished two month ago was smashed and I had 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! I came back to my truck and found a piece of 7" pipe 4’ long, but I needed a five footer! After using several words one of them just four letters long toward a superintendent who couldn’t tell a 6” from 7” pipe, I made a 15” long piece of 7” pipe from 6” pipe in less than a minute!  

How did I do it?

An answer to this question 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 you some time and help you to finish a job on time! So, for the price of only $1.00 I can explain how to do that.

6. Offset Calculation Tip

Some of the HVAC installers who are working in this field for some time know the formula:

M = ..............
Where: M – How much you have to miter a duct.
O – How much you want to off-set a duct.
W – Width of the 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 can see it in the picture. The problem here is: when you cut M from the duct it becomes shorter and it doesn’t reach to the point indicated by figure O.

In order to figure it out you are not supposed to be a super tin knocker, anyone who has C and higher - for geometry is able to solve this problem. I’ve resolved it in 5 minutes! 
How did I do it?
An answer to this question appears to be a very difficult one! You can do a research on the web as did I and find a very strange explanation with tons of geometrical formulas, which even I with my college degree couldn’t understand! Moreover, I can’t understand how an ordinary tin knocker can use those stupid formulas in the field anyway! So, for the price of only $1.00 I can explain how to do it.

7. "Jumper" Calculation Tip

What you can see in the picture is a “jumper”. When I ran a pipe from the joist space on the right to the joist space the left, I didn't even have a pipe there (in the joist space on the left). But anyway I have managed to make the 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 is 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" the right way. So, for the price of only $1.00 I can explain how to do it.

8. 6” Pipe Trick

Recently I was working in the basement, doing heat runs, and probably I was thinking too much on how to improve my website! As a result I put together too many six inch pipes – nine of them. When the job was done to my surprise I've discovered nine extra pipes all over the basement. I said to myself – it’s not a big deal! In less than a minute I took them all apart and put them 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 have read the answers, one of the EXPERTS even recommended to use a grinder to cut the pipe in pieces, another suggested - just throw them away and buy some new ones for only $7 a piece!!! But you are going to be astonished on how incredibly easy it actually is to unsnap a pipe! So, for the price of only $1.00 I can explain how to do it.
