Lennox Five-Ton Package Unit Price and Installation Costs

The Lennox five-ton package unit represents a compact, all-in-one heating and cooling solution suited for many mid-size homes in the United States. Because it combines cooling and heating components in a single outdoor cabinet, it can simplify installation compared with separate indoor air handlers and outdoor condensers. Prices vary widely based on model, efficiency, and the chosen heating method, while installation costs hinge on ductwork, electrical work, and local labor rates. This guide breaks down typical costs, configurations, and practical considerations for homeowners evaluating a Lennox five-ton packaged unit.

Overview Of Lennox Five‑Ton Package Units

A five-ton packaged unit delivers roughly 60,000 BTU of cooling capacity, a common size for fairly large homes or spaces with higher cooling demand. Lennox packages its units in several configurations, including gas/electric, electric/electric (air conditioning with electric heating), and heat pump (which provides both heating and cooling). In practice, a Lennox five-ton model is installed outdoors as a single cabinet, with the indoor air distribution system connected through existing ductwork. The all-in-one design can simplify service and maintenance, since refrigerant lines, wiring, and controls are centralized in one enclosure.

Efficiency and performance vary by model. High-efficiency Lennox packages typically feature advanced compressors, improved refrigerant circuits, and better SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. Homeowners should consider both cooling efficiency (SEER) and heating efficiency (AFUE for gas heat, or HSPF for heat pumps) when selecting a unit. The right configuration depends on climate, existing ductwork, and whether future energy costs or tax credits are a priority.

Configurations And Efficiency

Packaged units from Lennox generally come in three main configurations for five tons: gas/electric, dual-fuel or gas/electric with an optional electric strip heat, and all-electric heat pump. Gas/electric models use a gas furnace to deliver heating, while the outdoor unit handles cooling. All-electric heat pumps provide heat and cooling with refrigerant-based heating, which can be more efficient in milder winter climates. Dual-fuel arrangements combine a heat pump with a gas furnace to optimize efficiency and performance across seasons.

Efficiency ratings vary by model. The most efficient Lennox five-ton packages may exceed 16 SEER for cooling and offer higher heating performance through the chosen configuration. When selecting a model, it’s important to balance upfront cost with long-term energy savings. In regions with extreme winters, a gas-assisted option can offer reliable cold-weather performance, while milder climates may favor high-SEER heat pump configurations for lower operating costs.

Price Range For The Unit

The cost of the Lennox five-ton package unit itself, before installation, typically ranges from about $4,000 to $9,000. More affordable configurations tend to emphasize reliability and basic efficiency, while premium Lennox models with advanced controls, higher SEER ratings, or heat-pump capabilities can push toward the upper end of the range. Homeowners should expect that a unit price alone does not capture the total cost of ownership, as efficiency improvements can influence operating costs for years to come.

Configuration	Estimated Unit Price (USD)
Gas/Electric (including basic controls)	$4,000 – $7,000
All-Electric Heat Pump (5-ton)	$5,000 – $9,000
Dual-Fuel / High-Efficiency Models	$6,000 – $9,500

Note: Prices vary by model, manufacturer incentives, dealer pricing, and regional availability. Lennox equipped with premium features, variable-speed compressors, or advanced communications can push unit prices toward the higher end of the range.

Installation Costs And Factors

Installation costs for a Lennox five-ton package unit typically span from roughly $2,500 to $6,000 or more, depending on system complexity and site conditions. The total installed cost is the sum of the unit price plus labor, permits, and any required modifications to ductwork or electrical systems. Several factors influence installation costs:

• Ductwork Modifications: Existing ducts may need sealing, resizing, or reconfiguration for optimal airflow, which raises labor time and material costs.
• Electrical Upgrades: A new five-ton unit may require dedicated electrical service, new breakers, or upgraded wiring to meet code and unit specifications.
• A stable, level pad or mounting surface is necessary, sometimes involving minor concrete or surface work.
• Longer line sets or additional insulation add to material and labor costs.
• Installation of a new, often smarter thermostat or a building-wide control integration can add to the price.
• Permits And Inspections: Local permit fees and final inspections may contribute to total costs, especially in new construction or major renovations.
• Old Equipment Removal: Removing and disposing of an existing unit adds to the service charge, particularly if refrigerant recovery is required.

On average, homeowners report total installed costs in the range of $7,000 to $14,000 for a Lennox five-ton package unit, though sophisticated installations or high-efficiency models can exceed this range. The regional labor market and contractor expertise significantly influence final numbers. It is common to receive multiple quotes to compare included services, warranty terms, and timelines.

Regional Variations And Permits

Prices and timelines can vary by region due to climate, demand, and local labor costs. In parts of the Northeast and West Coast, installation can be more expensive due to higher labor rates and stricter building codes. Southern regions with milder climates may see shorter installation timelines and lower permit costs. Some areas require inspections for new HVAC installations, which can add days to a project. Homeowners should verify that the contractor is licensed, insured, and experienced with Lennox products and local permitting requirements.

Seasonality also affects scheduling and pricing. Approval processes may tighten during peak installation seasons (spring and fall), potentially raising labor costs or extending lead times. Planning ahead and obtaining written estimates early can help secure favorable pricing and ensure proper permit completion.

How To Compare Quotes And Choose A Contractor

Getting accurate quotes for a Lennox five-ton package unit requires clear communication about your home and goals. Start by confirming contractor qualifications: licensing, insurance, factory authorization to install Lennox equipment, and references. Ask for a written proposal that itemizes the equipment, labor, ductwork changes, permits, and disposal. Ensure the estimate includes a detailed warranty description and a maintenance plan. Consider the following steps:

• Define Your Configuration: Decide between gas/electric, heat pump, or dual-fuel configurations based on climate and energy costs.
• Request Separate Line Items: Itemize unit price, installation labor, ductwork work, electrical upgrades, permits, and disposal fees.
• Check Warranties: Confirm both parts and conditional labor warranties for the installed system and controls.
• Review Energy Features: Compare SEER, HSPF, compressor type (single-stage vs. variable-speed), and smart controls.
• Get References: Contact past customers to gauge reliability, responsiveness, and service quality.
• Estimate Timeline: Obtain a realistic install window and a contingency plan for potential delays.

A thoughtful comparison helps ensure the chosen Lennox five-ton package unit delivers expected comfort, efficiency, and long-term value. Homeowners should avoid jumping to the lowest bid if it lacks adequate equipment specification, warranty coverage, or clear installation scope.
