Welcome to TECH Method

TECH Method books are written by a veteran hands-on service technician (over 40 years), who has worked on everything from the smallest fractional horsepower systems, to ultralow temp cascade freezers, to 3600 ton centrifugal chillers.


These books offer no frills. No hype. No technical jargon. No complex formulas. Just plain English, step by step, how to find just about any problem (or combination of problems) in just about any system, and fine tune it along the way.


We are not out to impress you. We want to enlighten you. You don't care how smart we are. You care how smart you are.



The procedures we recommend have been thoroughly tested and refined, in the real world, on real HVACR equipment, for both speed and accuracy. The T.E.C.H. Method is not the ONLY right way to trouble shoot. It is just simply the BEST right way.
