Cost by Climate & AFUE Rating

Lennox furnace costs vary depending on your climate. Homeowners living in colder areas will need a higher Annual Fuel Utilization Efficiency (AFUE) rating, which will help keep your heating costs low.

Homeowners living in U.S. zones 1-3, warmer areas like Texas and California, can use a furnace with an 80% AFUE such as the Lennox Merit Series 180E, which costs $3,500 or $5,000 with installation.

However, in zone 5, much colder areas such as New York and Wisconsin, homeowners need a higher AFUE rating to manage heating costs during cold weather. Lennox has options for this, like the Signature Series SLP99V, which has a 99% AFUE rating and costs around $7,000 for the furnace, and up to $10,000 with installation fees.

Labor Costs for Lennox Furnace Installation

You can expect to pay between $2,000 and $6,000 for Lennox furnace installation. For easier installation, costs will be closer to the lower range, and more complicated installations will cost more.

Your labor costs depend on factors such as:

• Difficulty of installation
• Geographic location
• Existing ductwork or gas lines

If the new Lennox furnace is larger or smaller than your current furnace, the HVAC installer might have to make changes to your current ductwork, gas lines, vents, electric wiring, and hookups, raising your installation costs. If your current setup is similar to your new furnace and installation is less complicated, that will lower your installation costs.

Installation Tips: For the best value, consider your home size, climate zone, and installation requirements. Working with a licensed HVAC professional ensures accurate pricing and a unit tailored to your needs.

Factors That Impact Lennox Furnace Unit Costs

There are many factors that affect your furnace costs, including:

• Home & Furnace Size: Bigger homes will need a bigger furnace, which can raise costs.
• Efficiency: Lennox furnaces with higher AFUE ratings incur more upfront costs but can help you save on energy bills over time.
• Location: Labor, furnace type, and installation can cost more depending on your location.
• Installation Complexity: If the installer has to replace ductwork or vents, your costs will be higher than if the installation requires no replacements.
