Wayne The HVAC Guy

Hi I'm Wayne. Twenty-eight years ago, before I knew what a capacitor was, a contractor quoted me $6,800 to replace an AC system that turned out to need a $12 part and ten minutes of work.
I didn't have $6,800, so I spent that summer reading old service manuals and calling up retired techs until I figured it out. Fixed it myself for fifteen bucks.
That was the day I decided to learn this trade for real. Since then I've spent twenty-five years running service calls across three states, watching homeowners get the same treatment I got. Here I share what I wish someone had told me back then. 
The old-school diagnostics, the brand-name failure patterns, and the simple checks that turn $400 service calls into Saturday morning fixes. No upsells, no replacement quotes you don't need, just practical HVAC truth from someone who's been on both sides of the bill.
