Our diagnostic fee, up front
We charge a flat $110 diagnostic for a Summerville service call, and you hear that number when you book, not after. The technician finds the actual fault, gives you a written flat-rate price before touching anything, and if you approve the repair we apply the $110 to the job. Comfort Club members pay $0 for the service call. No surprise trip charges, no guesswork.
When a permit is required, and which county pulls it
Small repairs like a capacitor or contactor do not need a permit. Once a repair passes a certain dollar amount, and always for a full system replacement, a mechanical permit is required. A licensed contractor pulls it for you, schedules the inspection, and builds the fee into the quote. Which building department issues it depends on your county, and the Summerville area straddles two.
Dorchester County
Summerville proper, Knightsville, and Summers Corner.
Berkeley County
Cane Bay, Nexton, and Carnes Crossroads.
The two questions homeowners ask
The $5,000 rule
Multiply the age of your system by the cost of the repair. If the result is over $5,000, replacement is usually the smarter money; under that, a repair makes sense. A 12-year-old system facing a $450 repair lands at $5,400, which leans toward replacing, while that same repair on a 4-year-old system is an easy fix.
Full system replacement
A complete replacement in Summerville typically runs $7,000 to $14,000 installed, depending on the size of your home, the efficiency rating you choose, and whether the ductwork needs attention. We put the repair and replacement numbers side by side, and financing is available. See our Summerville repair vs. replacement guide.
