A Plea for HVAC Industry Standards Written for Technicians 1

Without the guys in the field, our industry would grind to an immediate halt.

Yet the volumes of industry standards published to lead and guide our industry are written in language, concepts, and formulae that are completely foreign to this critical group of people. Let’s take a look at this group’s plea for practical how-to industry standards written and published for use by the guys in the field. 

Why Maintenance Falls Short on Energy Savings
We all believe we save energy, so let's take a look at some reasons why energy savings are not being realized when typical residential and commercial maintenance programs are offered to our customers.
The Powerful Impact of Mentoring

My typical work day includes heartfelt conversations with both successful and wanting-to-be-more-successful HVAC professionals.

How to Plot Fan Airflow  2
Let’s take a look at how fan airflow can be plotted in less than five minutes to open the door to a new level of diagnostics and troubleshooting.
Use the Air Changes Calculation to Determine Room CFM 11
Engineering room airflow may present a real challenge when balancing an HVAC system. Most calculations only use the heat loss or gain of a room to decide on required airflow and often don’t take into consideration required room ventilation needs.
The Darker Side of Variable-Speed Blower Motors  7
Variable-speed blower motors have a variety of benefits, but little attention has been given to the potential of these motors to become energy hogs. Let’s look at precautions you must take when setting up equipment using variable-speed motors.
The Future of Energy Efficiency  2

I have a meeting with a group of energy regulators from Washington, DC tomorrow. My role in this meeting is to represent HVAC contractors who actually work in the field. My presentation at this meeting will describe elements of what HVAC energy efficiency may become in the future.
