The Lennox CX34 coil price typically ranges from $450 to $1,200 for the part plus $300-$900 for labor, depending on system size, refrigerant type, and access. This article lists real-world price ranges, per-unit rates, major cost components, and ways to lower the total replacement cost for a Lennox CX34 evaporator coil.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Replacement Coil (CX34) | $450 | $750 | $1,200 | Assumes common residential sizes 2–3.5 ton |
| Installation Labor | $300 | $550 | $900 | Includes 2–6 hours, basic access |
| Refrigerant Recharge | $40 | $125 | $300 | Per pound pricing; R-410A |
| Total Installed | $800 | $1,425 | $2,400 | Low: simple swap; High: multi-access, premium regions |
Typical Total Price To Replace a Lennox CX34 Coil
Buyers usually pay between $800 and $2,400 for a full replacement of a Lennox CX34 evaporator coil in a typical U.S. single-family home. Expect an average installed price near $1,400 for a 2.5–3 ton system in a suburban market.
Assumptions: Midwest labor rates, standard refrigerant R-410A, 2–3.5 ton coil, normal attic or furnace closet access.
Breakdown Of Parts, Labor, Equipment, And Disposal Costs
This table separates the main cost pieces contractors list on quotes for a CX34 coil replacement. Materials and labor dominate the total; equipment and disposal are smaller line items.
| Materials | Labor | Equipment | Delivery/Disposal | Contingency |
|---|---|---|---|---|
| $450-$1,200 (coil part) | $300-$900 (2–6 hours at $75-$150/hr) | $40-$150 (vacuum pump, manifold) | $25-$150 (old coil disposal, haul) | $50-$300 (hidden repairs) |
How System Size And Refrigerant Type Alter The Quote
Coil size and refrigerant affect both part price and labor: 1.5–2 ton coils run $450-$700, 2.5–3.5 ton coils run $700-$1,200. Switching systems from R-22 to R-410A or dealing with mixed refrigerant can add $300-$900 in retrofit work.
Numeric thresholds: a coil above 3.5 ton often requires special ordering and lifts (add $150-$400); refrigerant runs over 25 linear feet of line set may add $50-$200 for extra charge and leak testing.
Top Site Conditions And Specs That Drive The Final Price
Access, corrosion, and coil orientation are common variables: attic access adds 1–3 hours ($75-$450), plenum-mounted coils are quicker. Expect $150-$500 extra for difficult attic or crawlspace access or for rusted fasteners needing replacement.
Other drivers: old coil removal with contaminated system (acid flush) adds $200-$600; hard-to-find model numbers requiring a special-order coil add $100-$400 lead-time premium.
Practical Ways To Lower Lennox CX34 Replacement Price
Buyers can reduce cost by scheduling during off-peak months, preparing access, and avoiding unnecessary upgrades. Providing clear, safe access (clearing attic pathway, turning furnace switch off) can reduce labor time by 30%-50%.
- Get 3 written quotes and compare identical scope.
- Bundle with nearby HVAC work (air filter replacement, coil cleaning) to lower mobilization fees.
- Opt for OEM vs. aftermarket only when warranty matters; aftermarket can be 10%-30% cheaper but verify fit.
Regional Price Differences Across The U.S.
Prices vary by region: Northeast and West Coast averages run 10%-25% higher than Midwest; rural areas can be 5%-15% lower but add travel fees. Use regional deltas: Midwest baseline, Northeast +15%, West Coast +20%, South -5%.
| Region | Typical Installed Price | Delta vs Midwest |
|---|---|---|
| Midwest | $1,200-$1,500 | Baseline |
| Northeast | $1,380-$1,725 | +15% |
| West Coast | $1,440-$1,800 | +20% |
| South | $1,140-$1,350 | -5% |
Common Add-Ons, Time Estimates, And Hourly Rates To Expect
Typical job duration is 2–6 hours with a 2-person crew; contractor hourly rates commonly run $75-$125 per hour per tech. Allow for 2–6 labor hours and potential same-day diagnostic fees of $50-$150.
| Item | Typical Time | Rate/Unit |
|---|---|---|
| Technician labor | 2–6 hours | $75-$125 per hour |
| Gauge set & vacuum | 30–90 minutes | $40-$150 one-time |
| Refrigerant recharge | 30–60 minutes | $4-$9 per lb |
