it's not just the auto trade. my sons furnace went out so he calls a HVAC company........they tell him it can't be fixed and it will cost $3000 to replace it.
i replaced the blower control........it cost him $40.
i hate a crook.......
By far, the worst industry for that. No offense to rickairmedic on here, he's one hell of a guy, but he's a rarity in his field.
My a/c ***** (what I was on the phone with rick about, when I'm too far to even be a customer

). I called around and EVERY shop in town had the same line:
"How much do you charge for freon and to service, my evaporator is freezing?"
"Well, that depends on how many hours it takes."
"How many HOURS?"
"Well, we have to replace the furnace filter first."
"I just put a new one in a few days ago."
"Well, we have to do it."
"Ok, that still doesn't take hours."
"Well, then we have to clean your condenser and evaporator."
"Yeah, that was the first thing I did when it acted like that."
"We have to clean it ourselves."
"Then what?"
"We have to make sure the expansion valve is adjusted properly."
"It's been that way for 28 years, I'm pretty sure the adjustment is fine."
"Well, it could have came out of adjustment."
"What am I looking at for a total charge here?"
"$350-500 to get it service."

That was the standard answer for 30 shops.
Igniter went out midnight on a Friday night. I finally found a mobile tech that was out...
"I should be done here in 5-6 hours and can put it in."
"Yeah, the furnace has been off all day while I was at work apparently, it's cold in here. I already have the old one out, I can just pick up the new one and pay you for it."
"Well, I have to install it."
"What?"
"It's policy."
"How much for that?"
"Well, it's $75 for the igniter, but it's a minimum one hour charge, but since it's after hours, it's double time, so it'll be about $250."

I lit the damn furnace with wood matches and long needlenoses that weekend, found a part on Monday for $60.
The recent one was the furnace combustion fan...
"How much for a combustion fan for ******?"
"Well, the fan is $200, but we have to install it, that will be at least one hour labor."
"What? It's 4 screws and 3 wires. I already have the old one out, it took me 5 minutes, I'm not giving you $80 for that!"
I finally found out who supplies them with parts, woke up at 10 am, went there and got a fan for $145, and had the furnace running by 11:30am.
I REALLY hate (most of) the HVAC industry.
