The duct run behind a Mount Pleasant dryer
A century of accumulation in the core and a modern standard on the edges. In the older houses the appliances have been added over decades, so the connection behind each one dates from whenever it was fitted rather than from when the house was built, and improvised arrangements are common: extended supply lines, dryer ducts routed through available rather than suitable spaces, and ice supplies tapped wherever a pipe was reachable. Those are usually where the fault is.
That is the context for the one measurement that decides most dryer calls. The North Carolina residential code adopts IRC M1502.4.6: a maximum exhaust duct length of 35 feet, measured from the transition duct at the back of the machine to the terminal outside. Then the deductions in Table M1502.4.6.1 apply: five feet for every 90-degree elbow and 2.5 feet for every 45.
So 22 feet of actual duct with four right-angle bends in it is 42 feet of equivalent length, and it is over the limit by seven. It does not look over the limit. It looks like a short duct.
Below a certain air velocity lint stops being carried along and starts settling on the duct wall, so an over-length run progressively closes itself. Drying times stretch, the machine cuts out on its thermal protection, and eventually the heating element or the thermal fuse fails. That is the part everybody quotes, and fitting a new one into the same duct buys the same failure on the same schedule. The NFPA attributes roughly 14,000 home fires a year to clothes dryers and names failure to clean, meaning lint accumulation in the duct, as the leading cause.
We measure the run in Mount Pleasant, count the elbows, calculate the equivalent length and write it on your paperwork against the 35-foot limit. Where it is over we quote the rework as a separate line you can decline. Where it is simply dirty we clear it and say so, because that is the cheaper answer and it is frequently the true one.
The commercial position is the same in Mount Pleasant 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 Mount Pleasant itself changes
The kitchens in Mount Pleasant
Mount Pleasant has a listed historic district at its centre and newer building around the edges, and the difference between the two is not stylistic. In the historic core the kitchen is a room that was built for a different set of activities, and the appliances in it have been fitted into whatever space existed rather than into space designed for them. That means the practical constraint on any replacement is the room, not the budget: an appliance that is two inches deeper than the one it replaces may simply not close a door or clear a passage. We measure before recommending, and where a repair keeps an existing machine in a space that a modern one would not fit, that repair is worth more than its price.
The water and the power
Water service needs confirming for the specific address rather than assumed, as Mount Pleasant is outside the Charlotte Water area and the surrounding rural properties are frequently on private wells with their own chemistry. Duke for power. In the historic core the electrical service is the recurring caution: these houses have been rewired at various points over a long period, and what appears modern at the socket is not always modern at the panel.
Getting an appliance in and out
The historic core is the constraint. Original door openings, steps between the street and the door, and interior routes with more than one turn in them. Getting a modern appliance into one of those houses is a planned job rather than a routine delivery, and it is worth knowing before a purchase rather than after. The newer edges present none of that and are as easy as any subdivision.
