The Infinity 98 gas furnace price varies widely based on configuration, installation region, and whether the unit is purchased with or without additional components. This guide outlines typical costs, explains the main price drivers, and offers tips for budgeting, financing, and getting accurate quotes. It focuses on the Lennox Infinity 98, a high-efficiency gas furnace designed for precise comfort and energy savings in American homes.
What Is The Infinity 98 Gas Furnace?
The Infinity 98 is Lennox’s high-efficiency gas furnace that delivers comfort and energy performance for modern homes. It typically features a modulating gas valve and a variable-speed blower to maintain steady temperatures with minimal energy use. The unit is designed to operate quietly and to integrate with Lennox smart thermostats for precise control. As a premium model, it offers advanced features such as zoning compatibility and enhanced air filtration options. In climates with cold winters, the Infinity 98 can provide noticeable comfort improvements over standard furnaces while reducing annual fuel costs.
Key characteristics include an AFUE rating near the top of the residential range and compatibility with high-efficiency ventilation and ductwork setups. Installation quality and correct sizing are crucial to realizing the full efficiency and comfort benefits. The system is typically installed as part of a broader HVAC upgrade that may include a smart thermostat, air filtration, and, in some cases, humidification or dehumidification components.
Price Factors That Affect Infinity 98 Costs
- Furnace price versus installed cost. The base price of the Infinity 98 furnace is only part of the total. Labor, permits, and any required ductwork or venting updates add significantly to the final bill.
- Regional labor rates. Installation charges vary by market, with urban areas typically costing more than rural regions.
- Ductwork condition and modifications. Poor or undersized ducts, or the need for zone controls, can raise both materials and labor costs.
- Venting, gas line, and electrical work. Upgrading gas lines, clearance requirements, and electrical connections can influence price.
- Thermostat and smart controls. A programmable or smart thermostat, especially a Lennox iComfort model, may be included in the package or added as an upgrade.
- Warranty, service plans, and maintenance. Price can reflect extended warranties, maintenance plans, and after-sales support.
- Tax credits and rebates. Availability varies by year and location; rebates or incentives can affect the effective out-of-pocket cost.
Typical Price Ranges
Prices vary by region and project specifics, but the ranges below provide a baseline for budgeting. Note that the furnace price is different from the installed cost, which includes labor, materials, and any necessary adaptations.
| Scenario | Typical Price Range (US) |
|---|---|
| Furnace Only (Infinity 98) | $2,800 – $4,800 |
| Installed With Standard Ducts | $5,500 – $9,500 |
| Installed With Complex Ductwork Or Upgraded Gas Line | $9,500 – $12,000 |
The lower end reflects straightforward replacements in homes with adequate ductwork, while the higher end accounts for extensive ductwork upgrades, venting changes, or multi-zone systems. For homes with existing high-efficiency systems, upgrading to the Infinity 98 can still involve substantial labor if old components must be removed and modern controls installed. Always obtain a written, itemized estimate to compare what is included and to avoid hidden charges.
Financing, Rebates And Warranties
- Financing options. Many Lennox dealers offer financing plans or promotional rates to help spread the cost over time. These programs can make a premium system more affordable without affecting overall comfort or efficiency.
- Rebates and incentives. Utility incentives, local rebates, and manufacturer promotions can reduce the effective price. Check with local utilities and the installing contractor for current offers.
- Warranties. Warranty terms vary by model and installation specifics. Typical coverage includes a limited parts warranty and, in some cases, extended warranties for heat exchangers or critical components when registered and serviced regularly.
- Maintenance plans. Many installations include or offer maintenance plans that cover annual tune-ups and discounted repairs, helping preserve efficiency and longevity.
How To Get An Accurate Quote
- Request in-person assessments from licensed Lennox dealers. A qualified technician should perform a Manual J load calculation to determine the correct furnace size for the home.
- Ask for a written, detailed estimate. The estimate should itemize the furnace, labor, ductwork, venting, thermostat, and any add-ons.
- Compare equipment configurations. Ensure quotes reflect the Infinity 98 with equivalent features, including variable-speed blower and modulating burner.
- Verify installation scope. Confirm whether old equipment removal, new ventilation routes, and electrical panel work are included.
- Check for permits and inspections. Reputable installers handle permits and ensure the system is tested and commissioned to code.
Maintenance And Longevity
With proper care, the Infinity 98 can provide reliable comfort for many years. The typical lifespan for a high-efficiency gas furnace is 15–20 years, depending on usage, maintenance, and climate. Annual professional tune-ups help maintain efficiency, optimize gas pressure, and prevent breakdowns. Homeowners should replace filters regularly, inspect ductwork for leaks, and clean or replace air filtration components as recommended. A well-maintained Infinity 98 can deliver consistent comfort, better humidity control, and lower operating costs compared with older or less efficient units.
Choosing A Qualified Installer
- Licensing and insurance. Confirm the contractor holds applicable state licenses and carries liability and workers’ compensation insurance.
- Manufacturer-authorized status. Prefer installers authorized by Lennox to ensure proper handling of Infinity equipment and warranty validation.
- References and past projects. Ask for recent installations in your area and contact references about performance and service quality.
- Written guarantees. Request clear terms for workmanship warranties and what is covered under routine maintenance.
- Clear communication. A qualified installer should explain sizing, efficiency benefits, expected energy savings, and any variations in price upfront.
