I was in the appliance service business from around 1980 - 1995, then switched to software development because I didn't want to end up like the guys I worked with who had all sorts of joint damage from getting up and down off floors all day, and moving heave appliances.
24 years later, I left my job as a software engineer because I was losing my mind sitting in a cubicle, and just re-opened my service business. Right now I'm 100% COD and haven't even considered doing warranty work. Is warranty work worth the bother? When I used to do it, by the time I got done with the paperwork and bookkeeping and buying parts and returning them and tracking the credit, I don't believe I actually made any money on it. Is it better now, or still the same?
Also, there are things I've bumped into like the LG Linear compressor, which seems to be a spectacular idea implemented poorly, but at the end of the day, it's still just a normal refrigeration cycle.
Are there other significant changes?
Are electronics a big percentage of the problems or are standard things like clogged inlets/outlets/belts/heaters/damaged or loose wiring/thermostats/dirty-whatever/etc. still a large percentage of the calls?
I know this should probably go in PART, but I don't have access yet.
I'd appreciate any thoughts or opinions.
