How long does a typical Furnace Replacement take in Mount Pleasant, SC — and what can delay it?
- How is commercial furnace replacement different from residential?
- Commercial work usually means rooftop or packaged heating units (or make-up air units) that need crane access, curb adapters, and controls integration, and it's priced by unit scale rather than a flat residential range. Look for an installer who documents commercial/RTU experience, not a residential shop scaling a job up.
