$4,500 to $9,500 is a useful planning range for a standard residential furnace replacement in the Twin Cities as of September 2026, before unusual duct, venting, electrical, or structural work. Basic equipment swaps sit toward the lower end; high-efficiency, two-stage, variable-capacity, difficult-access, or code-correction projects move higher. The estimate should identify capacity, efficiency, thermostat, venting, condensate, permits, disposal, labor, and warranty. Do not compare an equipment-only price with a complete installed proposal.
What to ask next
The right next step depends on the system, the urgency, and the building. Keep the model number, symptoms, age, and any previous service notes nearby when you request an estimate. A professional should explain the diagnosis or sizing basis in plain language.
| Cost driver | Why it matters |
|---|---|
| Capacity and system type | Equipment and commissioning requirements vary. |
| Access and existing connections | Labor, venting, electrical, and disposal can move the total. |
| Permits and corrections | Required work should be visible in the written scope. |
