Lennox Merit Series 13ACX Cost and Typical Installed Prices 2026

The Lennox Merit Series 13ACX price varies by whether buyers buy the outdoor condensing unit only or a full replacement with labor and new coil; typical total installed prices range from $2,100 to $6,000. Buyers should expect the unit cost, labor, refrigerant, and any coil or line-set changes to be the main cost drivers.

Item	Low	Average	High	Notes
Outdoor Unit Only (13ACX)	$900	$1,450	$2,200	Assumptions: single-speed, standard 1.5–3.5 ton sizes.
Full Replacement (install)	$2,100	$3,750	$6,000	Assumptions: 2–3 ton home, moderate access, no major ductwork.
Commercial/High-Work Jobs	$4,500	$7,500	$12,000	Assumptions: large tonnage, crane or lift needed.

Typical Installed Price For a 2–3 Ton Lennox Merit 13ACX

For most U.S. single-family homes replacing a 2–3 ton AC, the Lennox Merit Series 13ACX installed price is usually $2,400-$4,200, with an average near $3,750. This average assumes a same-size swap, no major duct changes, and standard suburban installation access.

Assumptions: Midwest labor rates, 2.5-ton unit, standard matched indoor coil or existing evaporator compatible.

How the Quote Breaks Down Between Materials, Labor, and Fees

The main quote components are unit cost, labor, refrigerant and line-set, disposal, and permits—expect material to be 40–60% of the total on average.

Materials	Labor	Equipment	Delivery/Disposal	Permits
$900-$2,200 (unit) $150-$600 (coil/line-set)	$600-$1,800	$0-$600 (crane/risk)	$50-$250	$50-$300

Assumptions: Labor rate $75-$125 per hour, 4–12 labor hours depending on difficulty.

Unit-Only Price Ranges: Condenser Per Ton and Size

Buying the 13ACX condenser without installation typically costs $900-$2,200 depending on tonnage: 1.5–2 ton units trend $900-$1,300; 2.5–3.5 ton units trend $1,200-$2,200. Buyers replacing only a failed outdoor unit should verify the indoor coil match and refrigerant type before purchase.

Site Factors That Raise or Lower the Final Price

Access, height, and equipment lifts matter: rooftop or second-floor installations that need a crane add $800-$3,000; long line-sets over 50 feet add $150-$600; switching refrigerant types can add $300-$900. Hard-to-access installs and runs over 50 linear feet are common reasons a quote doubles compared with a simple ground-level swap.

Practical Ways to Reduce the Lennox 13ACX Price

Control scope by replacing only what is necessary, keep the same tonnage and coil if compatible, schedule in off-peak seasons, and get at least three written quotes. Removing homeowner obstacles (clear access, prepared work area) and bundling with a furnace tune-up often reduces labor hours and the overall installed cost.

Regional Price Variations Across the U.S.

Installed prices vary about ±15–35% by region: Northeast and West Coast typically run 15–35% higher than Midwest and Southeast; rural areas may have higher travel fees but lower permit costs. A $3,750 average in the Midwest may translate to $4,300-$5,000 in high-cost metro areas.

Common Add-Ons, Warranties, and When Costs Jump

Expect add-on costs for a new matched evaporator coil ($150-$600), new thermostat ($50-$250), extended warranties ($150-$600), and code-mandated refrigerant recovery ($75-$200). Major cost jumps happen when ductwork requires resizing, when electrical upgrades are needed, or when a change in refrigerant or tonnage is specified.
