A 5 ton evaporator coil typically costs $1,500-$3,500 installed, with higher quotes possible when refrigerant lines, drain pans, or system compatibility require extra work. The coil type, refrigerant, local labor rate, and access to the indoor unit are the main price drivers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Coil replacement, installed | $1,500 | $2,600 | $5,000 | Standard residential job to complex or premium installation |
| 5 ton coil only | $700 | $1,400 | $2,500 | Equipment price varies by brand and coil design |
| Labor | $500 | $1,000 | $1,800 | Usually several hours, excluding major system changes |
| Refrigerant and handling | $150 | $500 | $1,200 | Amount and refrigerant type affect the charge |
What a 5 ton evaporator coil replacement usually costs
For a typical home with a compatible central air system, a complete 5 ton evaporator coil replacement often totals $1,500-$3,500. The midpoint is about $2,600, including the coil, removal of the old part, installation, pressure testing, and refrigerant handling. Higher-end equipment or difficult access can push the bill toward $5,000.
Coil-only prices commonly run $700-$2,500 before labor and refrigerant. A 5 ton rating describes cooling capacity, not a guarantee that every coil will fit: the cabinet dimensions, metering device, refrigerant, and outdoor unit must match. Assumptions: standard residential equipment, normal access, and no major duct or refrigerant-line replacement.
A complete installed quote is more useful than comparing coil-only prices. It should identify the coil model, included refrigerant work, testing, disposal, and any warranty.
How coil, labor, and refrigerant charges shape the quote
Installers generally price the job as equipment plus labor, refrigerant work, and any required parts or disposal. A low equipment price may not include the metering device or the accessories needed to adapt the coil to the existing air handler or furnace.
| Quote component | Typical range | What can change it | Pricing unit |
|---|---|---|---|
| 5 ton coil | $700-$2,500 | Brand, cabinet style, availability | $700-$2,500 per coil |
| Installation labor | $500-$1,800 | Access, brazing, cabinet modifications | $75-$175 per hour |
| Refrigerant and recovery | $150-$1,200 | Refrigerant type and charge needed | $50-$150 per lb for many refrigerants |
| Drain, metering, and disposal | $100-$600 | New pan, valve, fittings, haul-away | $100-$600 per job |
Labor charges vary by market and service company. A basic replacement may take 4-8 hours; difficult removal, leak testing, or system adjustments can extend the visit. Ask whether the labor figure includes evacuation, leak checks, startup, and cleanup.
Which coil and refrigerant details raise a 5 ton quote
Compatibility can matter more than the nominal 5 ton capacity. A coil matched to a specific refrigerant and outdoor unit may cost more than a generic replacement, and a coil that does not fit the existing cabinet can require transition work. Variable-capacity or communicating systems can also need a designated coil rather than a basic model.
Refrigerant is a major price variable. Older R-22 systems can be costly to recharge, and replacement refrigerant may be limited or expensive; some owners compare a coil repair with replacing the full system. A coil designed for a newer refrigerant may not be a direct fit for an older condenser. Capacity mismatch, a line set longer than about 50 feet, or a unit located in a tight attic can add labor or parts.
Get written confirmation that the replacement coil matches the outdoor unit, refrigerant, metering device, and cabinet. A compatible part can prevent performance problems and repeat service charges.
How to lower the 5 ton coil replacement bill
Request an itemized quote from at least two licensed HVAC contractors, using the same coil specifications and scope for each. Compare warranty terms and included work, not just the bottom line. If a coil is still under a parts warranty, ask whether the manufacturer will cover the component and what labor remains out of pocket.
Keep the scope limited to necessary repairs. Replacing a drain pan, line set, or outdoor unit may be justified by damage or incompatibility, but those items should be explained and priced separately. Clear access to the indoor unit and scheduling during a less busy period may reduce delays or service premiums, though savings depend on the contractor.
A warranty-covered coil can still carry substantial labor and refrigerant charges. Confirm the warranty status and exclusions before approving work.
How installation time and access affect labor charges
A straightforward replacement often takes one workday, with 4-8 hours of hands-on labor. The technician must recover refrigerant, remove the old coil, install and braze the new one, pressure-test the circuit, evacuate it, recharge as needed, and verify operation. Depending on crew size and job complexity, labor commonly accounts for $500-$1,800 of the total.
Attic installations, narrow closets, or coils above finished ceilings can add time for safe access and protection of the home. If the technician finds a damaged refrigerant line, corroded fittings, or a drain problem, work may extend beyond the initial estimate. Ask the contractor to state the labor allowance and the hourly rate for approved extra work.
Regional labor rates shift installed coil prices
Installed prices are often higher in major metropolitan areas and regions with elevated wages, licensing costs, or strong seasonal demand. Compared with a national midrange quote, urban markets may run roughly 10%-25% higher, while some lower-cost rural markets may be 5%-15% below it. These are broad comparisons, not guaranteed local discounts.
Climate affects scheduling as well as price. In hot regions, peak summer demand can limit availability and prompt urgent-service charges; cold-weather markets may have different seasonal peaks. Requesting a quote before an active failure can provide more scheduling options. Use local quotes for budgeting because a national average cannot account for travel, demand, or regional labor rates.
When add-ons make a coil-only job a larger repair
Common extras include a new metering device, drain pan, condensate safety switch, refrigerant-line repair, and old-coil disposal. Minor fittings or disposal may add about $50-$250; a pan or safety-related upgrade can add $150-$600. Refrigerant recovery and recharge can add more when the system needs a substantial charge or uses an older refrigerant.
Ask the contractor to separate required items from optional upgrades and identify any work discovered after opening the system. A quote that includes only the coil may omit essential testing or refrigerant handling. Approve added work only after receiving its price and the reason it is needed.
Repairing the leak versus replacing the 5 ton coil
A leak diagnosis and minor repair may cost about $200-$1,000, depending on access and whether the leak is reachable. That can be less than replacement when the coil is relatively new and the leak is at a serviceable connection. However, repeated leaks, extensive corrosion, or a coil that is no longer supported can make replacement more practical.
Compare the repair price, expected reliability, refrigerant cost, and warranty coverage with the replacement estimate. If the outdoor unit is also old or incompatible with available refrigerant, request a separate whole-system quote before choosing a coil alone. Base the decision on the full repair scope and equipment condition, not the coil price by itself.
