Tech Tips:

Can Pulling a Vacuum too Fast Freeze Water/Moisture?

First, I want to give credit where credit is due. This post is made possible by the fantastic demonstration video by Neil Comparetto that I embedded below. Before you get bored and stop reading, I want to get the conclusion out in the air. Ice can form in a vacuum, but I still advise pulling a […]

Testing the Leak Rate on Your Micron Gauge Itself

As a technician gains skill, they will learn that regularly testing your tools is a huge part of success. It isn't long in the field before techs find out that just because a meter or gauge gives a particular reading, it doesn't ALWAYS mean it is correct. Vacuum is one of these areas. Everything in […]

How Long Should I Evacuate a System?

This article was written by Jim Bergmann with MeasureQuick. Anyone who has ever picked up a vacuum pump has asked or been asked this question. To be truthful, it is like asking, “How many licks will it take to get to the center of a Tootsie Roll Tootsie Pop?” In the words of the wise […]

What if you Only Have One Large Hose?

When evacuating, the FASTEST way is to use two large diameter hoses connected to two core removal tools and the cores removed. These hoses are then connected to the pump using a tee or evacuation “tree”. However, when you only have one large hose another acceptable method is to connect the large hose to the suction […]

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this comprehensive discussion, Bryan sits down with Brad Cooper, an experienced HVAC instructor from Arkansas, and JD Kelly, a trade school graduate, to tackle one of the most pressing questions in the HVAC industry: Is trade school worth it? Rather than offering a simple yes or no answer, the trio dives deep into the nuanced factors that determine whether trade school provides real value for aspiring HVAC technicians.

The conversation begins with Brad’s unique perspective as both a field technician with over 20 years of experience and a current instructor who transitioned to teaching five years ago. His father’s business background and the common frustration of having to “go behind people and fix stuff” motivated Brad to enter education, believing that proper training from the start could eliminate many field problems. JD brings the student perspective, having attended trade school while working full-time, which gives him insight into both the challenges and benefits of formal HVAC education.

A significant portion of the discussion focuses on what to look for when evaluating trade schools. The guests emphasize that the investment in laboratory equipment and facilities often reflects the school’s commitment to the program – you can tell immediately upon walking into a lab whether the institution truly prioritizes HVAC education. They stress the importance of accreditation, particularly from organizations like HVAC Excellence, which provides regular oversight and ensures schools meet industry standards. The conversation reveals that accreditation isn’t just about having a certificate on the wall; it represents a school’s willingness to submit to external scrutiny and maintain educational quality.

The discussion also addresses the critical balance between theoretical knowledge and practical application. All three speakers agree that the most valuable trade school experiences combine classroom learning with real-world field exposure through partnerships with local contractors, apprenticeship programs, or internship opportunities. They emphasize that instructor quality matters more than having the latest equipment – a humble, field-experienced teacher who can adapt to different student skill levels and learning styles proves far more valuable than someone with extensive theoretical knowledge but limited practical experience.
