Installing new systems sure. But diagnosing and repairing problems is far from it. You are mixing gas fired devices, compressors and refrigerants, pressurized water systems, electrical systems, and mechanical systems tieing all together. And just junking all those systems because a $5 part wore out as expected and the owners of the system are lied to that it is unfixable is a colossal waste of money and human labor. All just so corporate owners have more money to scrape off the larger margins of a full install of a new system which are going to break down just the same in a few years again.
