Our course is based on the International Codes. Most states have adopted the International Codes, although they may bare the name of a state, such as New York State Mechanical Code or North Carolina Mechanical Code.
Below Is a sample of the type questions you may encounter on the HVAC licensing exam. Our course will prepare you to confidently answer them.
1. Where the minimum size combustion air duct is 6” X 12”, a metal lover with unknown free area, must be at least _______ square inches
2. Calculate the required outdoor ventilation rate for a 1700 sq. ft. office space?
3. When installing B-
4. Calculate the velocity (FPM) of 800 CFM in an 8" x 14" duct.
5. If R-
6. If you purchase an appliance for $1000 and wish to make 30% profit; what would your selling price be? Hint: the answer is not $1300
We make learning easy
Once you've read our sections on Manual J (load calculations) and Manual D (duct design) you'll be looking for a butt kicking machine for not ordering our course earlier. There is simply no easier method for fully understanding these manuals.
Because many states are now adding business questions to their HVAC exams, we have included a section on business practices and math. It is written in a language, we in the trade understand. You no longer have to have the skills of a Philadelphia lawyer, mathematician and a CPA to help prepare for the exam.
BELOW IS AN EXCERPT FROM THE GUIDE TAKEN FROM OUR SECTION ON MANUAL J (load calculations)
This is a number indicating the ability of a substance to resist the flow of heat. The higher the R value, the better it acts as an insulator.
(Learn and understand U value. It is the foundation of a load calculation.)
The U value is the number of BTUs that pass though one square foot of substance in one hour’s time when there is one degree temperature difference. The U value is the reciprocal* of the R value. A U-
*A reciprocal of a number is 1 divided by the number. The reciprocal of 20 is 1/20 or .05.
Suppose you had a six-
Therefore, .0526 BTUs pass through 1 square foot of the batt each hour when there is one degree temperature difference.
If the batt measured 2’ x 8’ we would have a total area of 16 sq. ft. We could then say that .8414 BTUs (16 sq. ft. x .0526 BTUs). Pass through the entire batt in one hour when there is one degree temperature difference.
Carrying our example just one step further, if the temperature on one side of the batt is 20 degrees and on the other side it is 70 degrees, then we would have a 50-
Simply stated, use the following formula to determine the amount of heat gained or lost through any substance:
BTUH = U x TD X AREA
=.0526 x 50 X 16'
Once you know the U value, the square footage and the temperature difference, you can calculate the BTU heat loss or gain per hour through a substance. However, walls, floors and ceilings are not made up of just insulation. A wall may be made up of brick, sheathing, insulation and sheetrock, each of which has its own R value. The R value of each component must be added together to obtain the total R value. Then we simply take the reciprocal (1/R) and get the total U value of the wall. For a list of R-
I would like to inform you that I passed my exam (Master of HVAC). Your prep course was very good. Your knowledge and quick responses were responsible for my success. From here, I would like to shake your hand.

AN EXCERPT FROM THE GUIDE TAKEN FROM OUR SECTION ON THE FUEL GAS CODE
Single appliance -
What size B vent is needed for a 160,000 BTUH, naturally ventilated appliance if the total vent height is 18’ and the lateral 2’?
Under the height column you have to choose either 15’ or 20’. Remember this: The taller the vent the more capacity it has, therefore, if the 20’ row is used the vent may be under sized. Always use the shorter height.
In this case use 15’. Now use the 2’ lateral and select a vent size under NAT. A 5” vent will handle only 150,000 BTUH, while a 6” vent will handle 225,000 BTUH, therefore select a 6” vent.

Have questions ?
After spending hours in a cram course, listening to an instructor rushing to explain the provisions of all the code books, plus teaching you how to perform load calculations and size ducts, vents and piping and then covering business and accounting principles, the average attendee will come out of the class with one question on his mind; "What did he say?"
Most of us have been there before.
