That customer actually did you a solid by calling it out, crazy how people notice those little details sometimes lol. I bet most of us just swap brushes when they feel weird and hope for the best, but having a hard number like every 30 jobs makes way more sense. Must have been awkward in the moment though, getting called out like that in front of other people or whatever. Props to you for checking it and actually changing your system instead of getting defensive about it. Stuff like this is why I always keep spare heads in my kit now, just in case someone gets eagle eyes on me.

Man that tar stuff is the worst... I've seen that exact situation where people just keep piling new flooring on top of old instead of pulling it up, makes everything a nightmare when you finally gotta deal with it.

Yeah I remember reading something from Georgia Power about how lawn equipment barely registers on your bill because the chargers draw such low wattage compared to a clothes dryer or AC unit. Makes sense when you break it down, the batteries hold maybe a kilowatt hour or two total for the whole season. I switched last year and saw the same thing, the gas savings alone covers the minimal electric bump.

Man, you hit the nail on the head with that home fry test. I had a buddy who swore by this one place, said their breakfast was top tier. So we go, and the home fries were basically boiled potato chunks that sat in a puddle of oil. They had zero crunch, just greasy mush. And the toast? That fake margarine that feels like plastic on your tongue. My buddy was so let down he never went back. It's those little things, like you said, that tell you if they care or not.

Did you try cleaning out the lint trap housing and the exhaust vent while you had it apart? That was my main issue when I had the same problem - the vent was clogged with years of lint. I also found it helps to run the dryer on a shorter cycle first, then check the clothes instead of just setting it for the max time. Saved me a good bit on my electric bill too.
