5-Ton AC Coil Replacement Cost and Price Estimates 2026

Most homeowners pay between $1,200 and $5,000 to replace a 5-ton AC coil depending on coil type, access, and refrigerant. This 5-ton AC coil replacement cost guide lists realistic low-average-high ranges and the main price drivers so buyers can budget and compare quotes.

Item	Low	Average	High	Notes
Complete 5-ton evaporator coil replacement	$1,200	$2,400	$5,000	Assumptions: standard TXV or fixed orifice, easy attic or closet access, same refrigerant type.
Coil only (unit offsite)	$600	$1,400	$3,000	Assumptions: DIY swap or HVAC shop swap-in; excludes labor to remove old coil.
Line set swap / refrigerant change	$400	$1,000	$2,200	Assumptions: up to 30 linear ft, includes recovery and recharge.

Typical Total Price for Replacing a 5-Ton AC Coil

Replacing a 5-ton evaporator coil typically costs $1,200-$5,000 total. Expect $1,200-$2,800 for a straightforward coil swap and $2,800-$5,000 when access, brazing, refrigerant conversion, or duct changes are required.

Average jobs in many U.S. metro areas run near $2,400 and assume a standard aluminum-fin copper-tube coil, one technician crew, and 10-12 hours total on site.

Assumptions: Midwest labor rates, standard materials, normal access.

Breakdown of Materials, Labor, Equipment, and Permits

This table splits a typical quote into common line items so buyers can spot markups or missing charges. Materials and labor are usually the largest components; verify if the quote includes refrigerant and disposal.

Materials	Labor	Equipment	Permits	Delivery/Disposal
$600-$2,200 (coil, gaskets, TXV/filter drier)	$600-$1,600 ()	$150-$600 (vacuum pump, brazing tools)	$0-$300 (local HVAC permit)	$50-$250 (old coil disposal)

How Coil Type, Access, and Ductwork Change the Final Quote

Coil type: high-efficiency or microchannel coils cost 20%-60% more than standard copper-aluminum coils. Upgrading to a matched OEM coil or switching to R-410A/R-454B-compatible coil adds $400-$1,500.

Access: attic or tight closet access can double labor time; long lifts or scaffolding add $200-$800. Duct/return modifications or consolidation add $500-$2,000 depending on scope.

Niche thresholds: if line set run exceeds 30 linear ft add $300-$1,200; if evaporator coil requires a full plenum replacement add $800-$2,500.

Specific Ways To Reduce the 5-Ton Coil Replacement Price

Buyers can control scope, timing, and materials to lower cost. Choosing a like-for-like coil, scheduling during off-peak seasons, and preparing easy access can cut labor and equipment fees by 10%-25%.

• Provide attic access or clear workspace to avoid hourly access charges.
• Retain the same refrigerant and line set where safe to avoid costly conversion charges ($500-$2,000).
• Compare 3 written quotes and request itemized parts and labor.
• Consider contractor-supplied coil only if certified for installation to avoid warranty issues.

Regional Pricing Differences and What To Expect Locally

Prices vary by region: coastal metros and high-cost states run 10%-35% above national averages; rural areas can be 5%-20% below. Expect +20%-35% in California, New York City, and parts of New England versus the Midwest baseline.

Examples: a $2,400 average job in the Midwest may cost $3,000-$3,300 in a coastal metro and $1,900-$2,200 in a rural Midwest area.

Three Real-World Quote Examples With Specs and Totals

Example 1: Simple swap—5-ton copper-aluminum coil, same refrigerant, attic access. Materials $800, labor 8 hours @ $90/hr = $720, equipment $200. Total $1,720. Good-case scenario for like-for-like swaps.

Example 2: Line-set and refrigerant conversion—coil $1,400, labor 14 hours @ $95/hr = $1,330, line-set & fittings $850, refrigerant and recovery $650, permit $200. Total $4,430.

Example 3: Hard-access commercial closet—coil $2,000, labor 20 hours @ $110/hr = $2,200, scaffolding $600, plenum modification $1,200, disposal $150. Total $6,150 (high-end scenario).

Common Add-Ons, Minimums, and Fees That Inflate Quotes

Many quotes include add-ons that increase cost beyond the coil line item. Watch for diagnostic fees ($75-$200), minimum service charges ($150-$450), and rush fees (25%-50% surcharge).

Other common charges: brazing extra joints $100-$400, manufacturer core charge or return fee $50-$300, and additional refrigerant beyond standard fill $75-$400.
