Actual prices vary by tonnage, ductwork, and installer.

• Unit price (ML17XP1 condenser): approximately $1,900–$3,700
• Installation cost (standard replacement, existing ductwork): approximately $2,500–$4,000
• Complete installed price for a typical 3–4 ton system: commonly $4,400–$7,500

Prospective buyers should obtain multiple, written estimates from licensed HVAC professionals to capture regional pricing nuances. Also consider that factory-installed options, extended warranties, or dealer-added features can influence the final price.

Installation Cost and What Drives It

Installation cost reflects more than the unit price. Several factors influence the total invoice, and understanding these helps homeowners plan accurately.

• Tonnage and efficiency: Larger homes or higher cooling loads require bigger units, which can increase both the condenser price and the labor needed for setup.
• Ductwork condition: If ducts are leaky, blocked, or poorly sized, additional work may be needed to ensure proper airflow, driving up costs.
• Indoor equipment compatibility: The ML17XP1 pairs with Lennox indoor air handlers or furnaces. If a compatible indoor unit isn’t already in place, the project may require purchasing and installing that equipment as well.
• Refrigerant line set and insulation: Replacing or lengthening the refrigerant lines and adding proper insulation adds to materials cost and labor time.
• Electrical work and permits: New disconnects, breakers, wiring upgrades, and local permits can add hundreds to thousands of dollars depending on local codes and job complexity.
• Old equipment removal: Safely disposing of the existing condenser and any surrounding debris adds to labor costs but is often required.
• Thermostat and controls: Upgrading to a programmable or smart thermostat may incur a modest additional cost, but can improve comfort and efficiency.

On average, a standard ML17XP1 replacement with existing ductwork in a typical American home can land in the $4,000 to $7,500 range, while more complex installations or larger homes may exceed that range. Always obtain a written estimate that itemizes labor, materials, and any added equipment.
