The American Standard Allegiance 13 price typically ranges from an affordable basic unit to a mid-range installed furnace depending on size, venting, and ductwork condition. Buyers usually pay $2,000-$5,500 total for replacement installations; the main drivers are unit size (BTU), labor, and whether ducts or vents need work.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Allegiance 13 Unit Only | $700 | $900 | $1,200 | Single-stage gas furnace, common sizes |
| Standard Replacement (Installed) | $2,000 | $3,500 | $5,500 | 1-story home, existing compatible venting |
| Replacement + Duct/Vent Work | $3,500 | $4,800 | $7,000 | Includes moderate duct repairs or new B-vent |
| High-Complexity Install | $4,500 | $6,000 | $8,500 | Multi-story, new flue, code upgrades |
Typical Total Price For Allegiance 13 Furnaces Installed
Most homeowners see a total installed Allegiance 13 price between $2,000 and $5,500 for a complete swap of a like-for-like gas furnace. Expect the middle of that range for a 60,000–80,000 BTU unit in an average-size U.S. home with existing compatible venting.
Assumptions: Midwest labor rates, standard single-stage unit, basic thermostat, normal access.
Breakdown Of Quote Line Items And Their Costs
Contracts usually itemize materials, labor, equipment, permits, and disposal; understanding each line helps compare bids. Materials and labor typically account for about 70%-85% of the final installed price.
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (unit, filters, vent pipe) | $700 | $950 | $1,400 | Unit price varies by BTU and supplier |
| Labor (installation crew) | $600 | $1,500 | $2,500 | $75-$125 per hour; |
| Equipment Rental (crane, lifts) | $0 | $100 | $700 | Needed for rooftop installs or tight access |
| Permits & Inspection | $0 | $100 | $400 | Local code requirements vary |
| Delivery / Disposal | $75 | $200 | $600 | Removal of old unit and disposal fees |
| Warranty / Overhead | $50 | $150 | $400 | Factory warranty registration and contractor warranty |
How Furnace Size And BTU Rating Affect Final Price
Capacity is the biggest spec that changes the Allegiance 13 price; typical U.S. single-family homes use 40,000–120,000 BTU furnaces. Moving from a 60k–80k BTU unit to a 100k–120k unit commonly increases equipment cost by $200-$600 and labor by $150-$600.
Examples: 60k–80k (small/med) vs 100k–120k (large) and homes over 3,000 sq ft often require the higher capacity.
Site Conditions, Venting Type, And Ductwork That Drive Up Quotes
Factors like required new B-vent, switching to direct-vent, or extensive duct repairs add concrete dollars to the quote. Installing new venting can add $400-$1,200; replacing or majorly repairing ducts typically adds $1,000-$4,000.
Numeric thresholds: add $200-$600 if old unit uses B-vent and code requires new routed vent; add $1,000+ if duct leakage exceeds 20% or ducts need replacement.
Practical Ways To Lower The Allegiance 13 Installation Price
Controlling scope and timing is the most effective way to reduce price: schedule off-peak seasons, keep existing compatible venting, and avoid unneeded upgrades. Choosing a matching-capacity unit and doing pre-install prep (clear attic access, remove obstacles) can cut labor hours and save $200-$800.
Obtain 3 written quotes, request detailed line items, and compare warranties to avoid paying for redundant services.
Regional Price Differences And What To Expect
Labor and permit costs vary by region: coastal metro areas are typically 10%-30% higher than the national average while rural areas are often 10%-20% lower. Expect an installed Allegiance 13 to cost about $3,800 on average in high-cost metros versus $2,900 in lower-cost regions.
Estimate deltas: Midwest/South -10% to -20%, Mountain/Rural +0% to -10%, Northeast/West Coast +10% to +30%.
