The Lennox CH33 coil price for a straight replacement typically ranges from $800 to $3,200 depending on coil condition, tonnage, and installation complexity. Buyers usually pay more when the system requires matching refrigerant, cabinet modifications, or hard-to-access locations; this article lists realistic pricing ranges and main cost drivers for U.S. homeowners.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Replacement Lennox CH33 Coil (unit only) | $400 | $900 | $1,800 | Assumptions: 2-4 ton equivalent, OEM reman/new options. |
| Installed Total Price | $800 | $1,800 | $3,200 | Includes labor, basic fittings; no major duct changes. |
| Labor Only | $300 | $700 | $1,400 | Assumes 3-6 hours, $75-$125 per hour. |
Typical Total Price to Replace a Lennox CH33 Evaporator Coil
Most homeowners will see a total installed price between $800 and $1,800 for a standard 2–3 ton CH33 coil replacement under normal access conditions.
Low-end: $800-$1,100 for simple swaps using a remanufactured coil in an easy-access closet or utility room. Average: $1,200-$1,800 for new OEM coils for 2.5–3 ton systems with standard fittings. High-end: $2,000-$3,200 when cabinet modification, refrigerant conversion, or matched warranty upgrades are required. Assumptions: Midwest labor rates, standard single-family home, no ductwork changes.
Breakdown of Materials, Labor, Equipment, and Disposal Costs
Materials, labor, and special equipment are the largest line items; together they typically account for 85–95% of the installed price.
| Materials | Labor | Equipment | Delivery/Disposal | Overhead |
|---|---|---|---|---|
| $400-$1,800 (coil unit, gaskets, fittings) | $300-$1,400 (3-12 hours at $75-$125/hr) | $50-$300 (vacuum pump, manifold, brazing tools) | $25-$200 (old coil disposal, refrigerant reclaim) | $100-$300 (contractor markup, admin) |
How Coil Size, System Compatibility, and Access Change the Final Quote
Coil tonnage, cabinet fit, and access are the most impactful variables: moving from a 2-ton to a 4-ton equivalent can double the unit cost and add 1–4 labor hours.
Coil size/spec: 2.0–2.5 ton jobs: $400-$900 unit, 3.0 ton: $700-$1,100 unit, 3.5–4.0 ton: $900-$1,800 unit. Compatibility work: converting from R-22 to R-410A or changing metering devices typically adds $300-$900. Access: easy closet/attic hatch typically 2–4 hours; tight rooftop or deep crawlspace adds 4–10 hours and $300-$1,000 in labor/equipment time.
Practical Ways to Cut the Lennox CH33 Replacement Price
Control scope: choose a remanufactured OEM coil and complete basic prep work to lower cost without sacrificing function.
Options that reduce price: accept a remanufactured coil ($400-$800 vs. $800-$1,800 new), schedule in off-season for lower labor rates, and clear access (remove insulation, panels) to reduce crew time. Avoid unnecessary upgrades like premium warranties or matched high-SEER coil if not required by code or outdoor unit.

Typical Labor Time, Crew Size, and Hourly Rates for CH33 Coil Jobs
Most standard CH33 replacements require 2 technicians and 3–6 hours; expect $75-$125 per hour per technician in most U.S. markets.
Example labor scenarios: simple swap: 2 techs × 3 hours = 6 tech-hours; complex swap with refrigerant recovery and cabinet work: 2 techs × 6–10 hours = 12–20 tech-hours. Use the mini-formula above to estimate labor line item. Assumptions: certified HVAC techs, normal travel time.
Common Add-Ons, Permit Fees, and Disposal Charges That Raise the Final Price
Permits, refrigerant recovery, and cabinet modification are frequent add-ons that add $75-$900 to an otherwise standard quote.
Typical add-on ranges: permit/inspection $0-$250 depending on jurisdiction; refrigerant recovery/recharge $100-$600 depending on refrigerant type and amount; cabinet modification or coil box replacement $300-$900; expedited service or same-day fees $150-$400; disposal of contaminated coils or oil-logged systems $100-$300. Always confirm permit responsibility with the contractor.
How Prices Typically Differ Across Urban, Suburban, and Rural U.S. Markets
Expect urban metro areas to run 10–25% above national average, while rural markets can be 5–15% below average depending on local labor supply.
Example deltas: coastal metro (NY, CA) average +15–25%; Sun Belt suburban (TX, FL) average ±0–10%; rural Midwest average -5–15%. Material shipping to remote locations can add $50-$300. Assumptions: same job scope and coil model.
