HVAC LICENSING EXAM PREP COURSE

“So easy, your dog could pass!”

Question: 1 ton of refrigeration = ____ btu’s?

 a.188,000  b. 12,000  c. 288,000  d. 2,000

This is a Gotcha question.  A “ton of refrigeration” is defined as the amount of btu’s required to melt one US ton of ice  in 24 hours.

When we melt ice, we are in effect, changing the state of water from a solid to liquid,without changing the temperature. Energy required to change the state of a substance is called latent heat. When changing from a solid to a liquid, it is called latent heat of fussion. the latent heat of fussion is 144 btu’s per pound of water. Therefore, it takes 144 btu’s to melt one pound of water (ice). Two thousand  pounds  x 144 btu’s = 288,000 btu’s. If, you divide 288,000 by 12 hours, you will get the 12,000 btuh you were looking for. Nevertheless, it takes 288,000 btu’s to melt a ton of ice. Therefore, 1 ton of refrigeration = c. 288,000 btu’s

“Guide to Passing the HVAC Licensing  Exam

Think about it!

After spending hours in a cram course, listening to an instructor rushing through 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.
The Guide is simply the best way to go.

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. For example, the Guide condenses Manual J from 627 pages down to 11 pages; Now, that’s making it easy

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.
