What a Statesville oven is fitted into
Two entirely separate answers. In the districts, appliances added piecemeal across a century, connections that date from whenever each one was fitted, and the recurring finds that go with that: extended and improvised supply lines, dryer ducts routed opportunistically, and circuits carrying more than they were laid in for. In the subdivision ring, a straightforward modern installation with the usual over-length upstairs dryer duct. It is worth knowing which before quoting.
The reason that matters is that ovens are where the repair-or-replace arithmetic most often misleads people, and the misleading part is the installation rather than the appliance.
The rule people apply is the fifty percent rule: do not spend more than half the cost of a comparable new appliance on repairing the old one. It was written about a machine you can wheel out of a shop. A wall oven is cut into a cabinet. The aperture has a width, a height and a depth, the trim overlaps the surrounding joinery, and the appliance is usually hard-wired rather than plugged. Replacing one means finding a current model that fits an opening built around a unit from ten or twenty years ago, and where it does not fit you are into a joiner altering a fitted kitchen. So a $400 repair on a wall oven in Statesville is not competing with a $700 appliance, it is competing with an appliance plus an electrician plus quite possibly a joiner. We measure the aperture and check the connection before recommending either way.
The other thing worth publishing, because it costs us work to say it: the self-clean cycle is the leading cause of the dead ovens we attend. Pyrolytic cleaning takes the cavity to 800 or 900F for two to four hours, far beyond anything cooking requires, and three things fail as a result. The thermal fuse, which is a one-shot device fitted precisely so it goes before something costlier does. The control board, which lives immediately above the cavity where the heat rises. And the door lock motor, which leaves the oven dead and locked shut.
So the advice is simple. Do not run self-clean the week you need the oven, and preferably do not run it at all. Clean the cavity cold, by hand. It is tedious and it blows nothing.
The commercial position is the same in Statesville as it is at a Charlotte address, because the rate card on this site is not a Charlotte rate card. The diagnostic visit is $89 and it comes off the invoice in full when you approve the repair. Labour beyond that is $95 to $145 an hour. Nothing is added for the drive, and if the same fault returns after we have fixed it the return visit carries no fee at all.

What Statesville itself changes
The kitchens in Statesville
Statesville has been a town since 1789, it is the Iredell county seat, and it carries three National Register districts: Academy Hill, mainly 1885 to 1930, South Race Street, and the Commercial district from roughly 1875 to 1925. Around them sits a newer subdivision ring built since 1990. That gives this town the largest concentration of genuinely pre-war kitchens in the service area, and the defining characteristic of a pre-war kitchen is not its size. It is that it has no dedicated circuits in it. Everything in those rooms has been added to a wiring scheme that predates the idea of a kitchen containing more than a light and a socket.
The water and the power
The City of Statesville runs its own water supply, so the Charlotte figures are not the local ones and the soft-water reasoning is checked against the city report before it is applied. Duke for power. The electrical service in the historic districts is the recurring practical constraint here more than anywhere else in the service area: adding a hard-wired appliance to one of those houses genuinely means a new circuit, and that is licensed electrical work that we hand over rather than absorb.
Permits and who is licensed
Swapping an appliance on an existing connection does not require a permit anywhere in this service area, and we will tell you that rather than adding a line for one nobody filed. What is regulated is the connection itself: new or altered wiring for a hard-wired appliance falls under the North Carolina electrical board, and anything on a gas supply line falls under the plumbing and heating board. Neither is appliance work and we hand both to the licensed trade. Whether the City of Statesville or Iredell County reviews the work depends on the address. In the historic districts a new circuit for a hard-wired appliance is a genuine job and it is licensed electrical work rather than ours.
