This article lists realistic pricing, key cost drivers, and practical ways to lower the final replacement price for a Lennox CX35 coil.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| CX35 Coil Part | $350 | $600 | $1,100 | Aftermarket vs OEM, coil size |
| Installed Replacement | $750 | $1,400 | $2,400 | Includes labor, minor modifications |

Typical Total Price To Replace a Lennox CX35 Coil
Most homeowners pay $750-$2,400 total to replace a Lennox CX35 coil, with the average around $1,400. Expect part-only pricing of $350-$1,100 and labor that adds $400-$1,300 depending on difficulty.
Assumptions: Single-family home, basement or attic access, standard 2–3 ton system, Midwest labor rates.
Breakdown Of Parts, Labor, Equipment, And Disposal
| Materials | Labor | Equipment | Delivery/Disposal |
|---|---|---|---|
| $350-$1,100 (coil); $40-$120 accessories | $400-$1,300 () | $0-$200 (lift, vacuum pump rental) | $25-$150 (old coil disposal) |
Materials typically represent 30–60% of the part-only budget while labor dominates when access or cabinet work is required.
How Size, System Type, And Coil Model Change The Quote
Coil selection varies by capacity and cabinet match: 1.5–2 ton coils cost less, 2.5–3.5 ton and XL configurations cost more. Expect a $150-$400 jump when moving from a 2-ton to a 3.5-ton coil and $200-$600 extra for matched OEM assemblies versus universal coils.
Numeric thresholds: 2.0 ton (24k–26k BTU) vs 3.5 ton (42k–45k BTU); cabinet modification >2 linear ft increases labor 1.5–2×.
Site Conditions And Access That Drive Labor Hours
Labor ranges from 2–10 hours typically; tight rooftop, attic, or equipment stacked in closets push hours up. Plan on 2–4 hours for easy access, 6–10 hours for attic or rooftop work that requires sheet-metal alterations.
Assumptions: Typical tech rate $75-$125 per hour; removal and recharging extra if refrigerant recovered.
Cost-Saving Choices When Replacing a CX35 Coil
Choosing a universal coil, scheduling during off-season, and bundling with other HVAC work reduce the total price. Replacing just the coil rather than the entire evaporator cabinet can save $400-$1,200 when cabinet is undamaged.
Other tactics: provide clear access, remove personal obstacles pre-visit, get 3 written quotes, and verify whether an OEM coil is required by warranty.
How Regional Prices Change Lennox CX35 Coil Estimates
Regional labor and market variances typically shift installed prices by ±15–40%. Expect 10–25% higher installed totals in coastal urban markets and 10–20% lower in many rural or Midwestern areas.
| Region | Typical Installed Range | Relative Delta |
|---|---|---|
| Northeast / Metro | $900-$2,500 | +15% to +40% |
| Midwest / Suburban | $750-$1,600 | Base |
| South / Mixed | $700-$1,900 | -5% to +25% |
| West Coast / Urban | $1,000-$2,700 | +20% to +45% |
Common Add-Ons, Permits, And When Replacing Makes Sense
Additional costs include refrigerant recovery/recharge $150-$450, new filter driers $25-$75, orifice/tuning $40-$150, and permit fees $0-$200. Replacing the entire evaporator assembly costs $900-$3,200 but is necessary if the cabinet, drain pan, or coil match is incompatible.
Diagnostic fees often apply; expect $75-$150 waived if contractor wins the job. Verify local permit needs before budgeting.
