Any single article from a good writer is worth reading, and then reading again.
Such is the case for David Richardson, vice president of training for National Comfort Institute (NCI) and a contributor to Contracting Business.
Two of Richardson’s specialties are airflow and the High-Performance HVAC™ approach, which he teaches at NCI and other industry events.
The gallery above describes three of David’s best articles that focus on popular topics here at Contracting Business: Superheat and Subcooling, and Thermostatic Expansion Valve Misdiagnosis. His articles explore how these refrigeration-side topics have a powerful impact on airflow, which directly affects comfort and energy efficiency.
David’s technical advice and commentaries, though geared to the HVAC technician, apply to management and sales as well.
Without further ado, here are three of his top articles:
- Introduction to Superheat and Subcooling Diagnostics: https://www.contractingbusiness.com/service/article/21247583/introduction-to-superheat-and-subcooling-diagnostics
