In the late eighties the senior service technicians (SST’s) developed the "Superior HVAC Service Technicians Creed", the idea was to set goal’s for themselves on how best they could serve their customer’s, their industry, fellow employee’s and their apprentices.

The Ten Commandments of the Professional  

HVAC Service Technician


#1 KNOW that you must ALWAYS use the appropriate Safety Gear!

#2  KNOW that 95% of all unit failures is from some form of DIRT or contamination!

#3  KNOW that you must ALWAYS check the disconnect!

#4  KNOW that you must ALWAYS double check the wiring!

#5  KNOW that water freezes @ 32 degrees Fahrenheit and 0 degrees Centigrade!

The benefits of all of this are too numerous to mention here but the most important are satisfied customers and an extremely low warranty and call back costs. In 2001 the service department experienced, in labor hours, a warranty call back rate of .0039%, an outstanding performance by an outstanding group of people.
