The price and cost to install an Infinity® 21 Central Air Conditioner 24ANB1 typically runs from equipment-only to fully installed with ductwork and controls; main drivers are unit capacity, installation complexity, and local labor. Buyers should expect the 24ANB1 price to vary by region, SEER/efficiency options, and whether a matched indoor unit and controls are included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Equipment Only (24ANB1, 2–5 ton) | $1,800 | $3,200 | $4,500 | Assumptions: base condenser, factory warranty, no accessories. |
| Installed (standard replacement) | $4,500 | $7,500 | $11,000 | Assumptions: 3-ton, matched air handler, 1-day install, suburban area. |
| Installed with ductwork/controls | $6,500 | $10,500 | $15,500 | Assumptions: moderate duct repairs, upgraded thermostat, permit fees included. |
Typical Total Price for a 3-Ton Infinity 21 24ANB1 System
Most U.S. homeowners replacing a 2.5–3.5 ton system pay between $4,500 and $11,000 installed for the 24ANB1 depending on matching indoor equipment and extras. An average full-install price for a matched 3-ton Infinity 21 system is about $7,500.Assumptions: 3-ton condenser, standard matched air handler, 1–2 supply runs, suburban labor rates.
Breakdown of Major Quote Parts: Materials, Labor, Equipment, Permits
Typical quotes separate the condenser, indoor unit, refrigerant, labor, and permits; warranties or accessories are often itemized. Customers should insist on a line-item quote to compare components and labor hours.
| Materials | Labor | Equipment | Permits |
|---|---|---|---|
| $1,800-$4,500 (condenser) + $600-$3,000 (air handler) | $1,200-$3,500 () | $100-$600 (thermostat/controls) | $50-$500 (local) |
| Filters, refrigerant, sheet metal $100-$800 | 2-16 hours typical, $75-$125 per hour | Matching coils or line sets $200-$900 | Some cities require system permits and inspections |
Key Variables That Change the 24ANB1 Final Quote
Capacity selection, duct condition, and needing a matched air handler are primary drivers; two niche variables are refrigerant retrofit and SEER tuning. A refrigerant retrofit (R-22 to R-410A) adds $800-$2,500; upgrading from a 16-SEER to Infinity 21-level controls can add $1,200-$2,500.
Numeric thresholds that matter
– Duct repair: minor patching $300-$1,200; full duct replacement $3,000-$8,000. – Line set/run length: standard up to 25 ft included; each extra 10–25 ft adds $150-$400.
Practical Ways To Reduce 24ANB1 Installation Price
Control scope, time work for off-peak seasons, and provide clear access to the mechanical area to lower labor hours. Choosing a slightly lower-capacity matched condenser/air handler combo within proper sizing and accepting standard rather than premium filters saves $700-$1,800.
How Regional Prices Compare Across the U.S.
Prices vary: urban coastal markets command premiums while Midwest and South are often lower. Expect roughly +10% to +30% in high-cost metro areas and -10% to -20% in lower-cost rural zones compared with the national average.
| Region | Typical Installed Range | Delta vs National Avg |
|---|---|---|
| Northeast (urban) | $6,500-$12,000 | +10%–+30% |
| Midwest | $4,200-$8,500 | -10%–+5% |
| South | $4,000-$9,000 | -10%–+10% |
| West (coastal) | $6,000-$13,500 | +15%–+35% |
Typical Labor Time, Crew Size, and Installation Duration
Installation time varies with scope: straight condenser swap is 4–8 hours; full system change with coil and thermostat is 8–16 hours. Most installs use a 2-person crew; expect 1–2 working days on-site for standard residential jobs.
Common Add-Ons and Permit Costs That Affect Final Price
Frequent add-ons include upgraded thermostats ($100-$600), surge protection ($150-$450), extra refrigerant ($50-$250), and disposal fees ($75-$250). Permits and inspection fees typically add $50-$500 depending on locality and whether duct modifications trigger additional permits.
