The modeled typical cost is $4,122, with a planning range of $3,092 to $5,565 for 900 sq ft home.
Computed cost breakdown
| Line item | Arithmetic basis | Amount |
|---|---|---|
| Materials | 900 sq ft home × indexed material rate | $2,306 |
| Labor | 900 sq ft home × indexed labor rate × 1.00 | $1,381 |
| Permits | Baseline allowance | $300 |
| Disposal | 900 sq ft home × disposal rate | $135 |
| Typical total | $4,122 | |
Low $3,092 · Typical $4,122 · High $5,565
Difference from the parent scenario
This quantity-specific total is 48.1% below the parent default of $7,945. The arithmetic changes quantity while retaining the parent model’s rates and national wage factor.

Primary cost controls
- Equipment capacity and efficiency
- Ductwork or electrical changes
- Number of zones
- Climate and design load
This worksheet starts with home area to form a furnace-capacity planning scenario, then attaches the modeled equipment and installation budget. It does not perform a room-by-room Manual J load calculation or select fuel, venting, duct changes, electrical work, or combustion-air requirements. Use its capacity result to frame questions; require the installer to document the design load and chosen furnace output.
