That is cheap. What area is this?
When I say appliance I mean, Stove, oven,washer, dryer, dishwasher, fridge, freezer.
And in Brooklyn, Flatbush/BoroPark.
$50-$75 is very reasonable, you can't charge more for just coming to look at the problem, and it's usually something that can be fixed so it's included in the total repair cost, whether it being an Igniter on an oven for $125 it would be included.
