The duct run behind a Salisbury dryer
A century of accumulation. Appliances fitted into spaces adapted for them, connections dating from whenever each appliance was installed, supply lines extended to reach positions that suited the room rather than the plumbing, and dryer ducts routed through whatever was available. In a house of this age the connection behind the appliance is worth more attention than the appliance itself, and it is frequently where the fault turns out to be.
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 Salisbury, 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 Salisbury 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 Salisbury itself changes
The kitchens in Salisbury
Salisbury holds one of the most substantial historic housing stocks in North Carolina, across the Salisbury Historic District, North Main Street from roughly 1900 to 1930, Brooklyn-South Square and North Long Street-Park Avenue, in Late Victorian, Colonial Revival and Craftsman bungalows in real quantity. For appliance work that produces a specific and unglamorous problem: this is the hardest town in the service area to physically get an appliance into or out of. Original door openings, narrow stairs, interior routes with several turns, and kitchens at the back of houses that were designed around a service arrangement nobody uses now.
The water and the power
The City of Salisbury runs its own water supply, so the Charlotte hardness numbers are not the ones that apply here and the dishwasher reasoning is checked against the city report first. Duke for power. In housing of this age the electrical service is the standing constraint: the wiring has been renewed in stages by various people over a century, and what is modern at one socket is not necessarily modern at the panel, which is worth establishing before adding load.
Getting an appliance in and out
The defining feature of working in this town, and it changes the economics of a repair. A refrigerator that came into one of these houses twenty years ago may not come out of it now, because a door has been replaced, a wall has been built, or the appliance was carried in before something else was fitted. Where that is the case a repair is not competing with a replacement on price, it is competing with a replacement that may not be practical at all. We establish the route before recommending either.
