HVAC Troubleshooting Part 2

January 12, 2025

In another class from our training series from Polar Bear Air Conditioning, Bryan Orr presents Part 2 of HVAC Troubleshooting fundamentals. Learn about the critical relationship between suction pressure and evaporator temperature, liquid pressure and condensing temperature, and how subcooling indicates liquid stacking in the condenser.

Bryan explains why common practices like running continuous fan operation can worsen humidity issues in humid climates, and shares practical diagnostic approaches including isolation diagnosis for electrical issues. This session includes valuable insights on delta T measurements, the impact of humidity on system performance, and how to properly diagnose transformer and fuse problems.

Key topics:

Temperature and pressure relationships
Humidity effects on system performance
Isolation diagnosis techniques
Low voltage troubleshooting
Delta T considerations in humid climates

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.

This unique podcast episode is a commentary on the phenomenon of “white shirt techs” in the HVAC industry – a term that refers to technicians who focus heavily on sales and maintaining a pristine appearance rather than technical expertise. While there’s nothing inherently wrong with having good sales skills or maintaining a professional appearance, there needs to be a balance with actual technical competency. The episode serves as part of a manifesto series heading into 2025, addressing important industry trends and concerns.

There is a delicate balance between sales and service in the HVAC industry, particularly in residential services. Some companies and technicians may prioritize metrics like average ticket price and five-star reviews over providing genuine solutions to customers’ problems. While it’s important to discuss money and options with clients, we shouldn’t resort to fear tactics or make promises that products can’t fulfill, particularly in areas like indoor air quality solutions and UV lights.

The podcast raises important questions about professional identity and integrity in the HVAC field. Technicians should occasionally step back and think about whether they’ve lost their passion for actually fixing equipment and solving technical problems in favor of focusing solely on sales. He argues that the best residential technicians maintain their interest in the mechanical aspects of the work, even as they develop their customer service and sales skills. The episode concludes with a call for technicians and companies to invest more time in technical training and to maintain their commitment to solving real problems rather than just selling solutions.
