Typical Installed Price For an Infinity 21 24ANB1 in a Single-Family Home
Expect a total installed price of $3,200-$8,500 for the Infinity 21 24ANB1 depending on tonnage and installation complexity. A common average for a 3.5-ton replace-in-place installation is $4,500-$6,000 installed.
Assumptions: Midwest labor rates, matched indoor coil, standard 2,000 sq ft home, accessible equipment location.
Materials, Labor, Equipment, and Permit Cost Breakdown
Typical quotes group costs into materials, labor, equipment, permits, and disposal—each can shift the final price considerably.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $1,200-$3,200 (unit) | $900-$2,500 (install labor) | $200-$900 (crane, rigging) | $50-$400 | $75-$300 |
| Coils, linesets, pads | 4-12 hours × $75-$125/hr | Lift, vacuum pump, gauges | Local code fees | Old unit haul & disposal |
Which Specs Affect the 24ANB1 Price Most: SEER, Tons, Ducts
SEER rating, tonnage, and duct condition strongly change the price; choosing a higher SEER variant or larger tonnage raises unit cost and possible permit needs. Expect unit price increases of $200-$800 when upgrading from base SEER to higher-efficiency models per ton.
Specific numeric thresholds: smaller 2-2.5 ton jobs often fall near the low end ($3,200-$4,000 installed), while 4-5 ton systems push $6,500-$8,500 installed, especially with duct repairs. Poor ducts can add $1,000-$5,000 depending on extent.
Practical Ways To Reduce the Price on a 24ANB1 Purchase
Control scope: replace only the outdoor unit if indoor coil and ducts are in good shape, and schedule installations off-peak to lower labor rates.
Other tactics: get three written quotes, accept contractor-provided standard brand-matched coils instead of premium aftermarket coils, bundle with furnace replacement for labor savings, and complete prep work (clear access, remove obstacles) to reduce crew hours.
Regional Price Differences for the Infinity 21 24ANB1
Prices vary by region: expect 5%-15% higher pricing in coastal urban markets and 8%-20% lower pricing in rural Midwest or South-Central markets. Typical regional delta: Northeast urban +12%, West Coast metro +10%, Midwest rural -10%.
Assumptions: labor share, permit costs, and market demand influence these deltas.
Installation Time, Crew Size, and Typical Labor Rates
Basic replace-in-place jobs take 4-8 hours with a two-person crew; complex swaps with duct work or coil changes take 10-18 hours. Labor rates typically run $75-$125 per hour, so labor line items commonly total $900-$2,500.
Plan for additional same-day diagnostic and startup time of 1-2 hours and an extra service call fee if scheduling outside normal business hours.
Common Add-Ons, Zoning, and Warranty Options That Raise Price
Frequent add-ons include upgraded thermostats ($150-$400), zoning systems ($500-$3,000), extended warranties ($150-$600), and surge protection ($100-$400). Zoning with motorized dampers usually adds $1,000-$2,500 for a modest multi-zone job.
Factory warranty is typically included with the unit; extended labor warranties or transfer options increase the total cost but can lower long-term expense risks.

Questions That Will Change The Quote When Requesting Estimates
Be ready to answer questions about home square footage, attic access, existing duct condition, desired SEER, and whether a matched indoor coil is required. Answers to these typically move an estimate by $500-$3,000.
