| Gas | $1,100 – $3,700 | $3,000 – $9,500 |

Remember to register your new furnace with Lennox soon after the purchase. Some manufacturers offer longer warranties for customers who register their furnaces within 30 to 60 days.

The Lennox furnace unit itself makes up 35% to 40% of the total replacement cost, while labor makes up the remaining 60% to 65%, with your final cost depending on the furnace model, size, efficiency, and other factors.
| Factor | Average cost |

The following factors also affect the cost of a Lennox furnace:
Efficiency: The U.S. Department of Energy requires all furnaces made after 2014 to have at least a 78% Annual Fuel Utilization Efficiency (AFUE) or higher. Most modern furnaces exceed this standard. Lennox furnaces have efficiency ratings of 80% to 99%.
Furnace size: Large houses require bigger, more expensive furnaces. Most homes need 30 British thermal units (BTUs) per square foot, or 60,000 BTUs for a 2,000-square-foot home. Homes with poor insulation, closed floor plans, or older windows may need a bigger furnace.
Climate: Homes in the northern U.S. experience more severe weather and need higher-efficiency furnaces with a 90% AFUE or more. Homes in the southern U.S. may only need a furnace with an 80% to 90% AFUE.
Maintenance: Furnace cleaning costs $70 to $100 for basic services and $150 to $300 for advanced cleaning. A furnace inspection costs $70 to $130 or $150 to $500 for annual maintenance. This includes a tune-up, inspection, and minor repairs.
Repairs: Furnace repairs cost $75 to $150 per hour before parts, or $125 to $480 total on average.
Labor
Most Lennox furnace installers charge $1,900 to $5,800 in labor costs in addition to the unit price. Complicated installations will cost more in labor, while simple installations or replacements cost less.
Some newer furnace models may be a different size than your old unit, which may lead to higher costs for changing ductwork, existing gas lines, hookups, wiring, or vents. You may also need to install intake and exhaust piping for high-efficiency models.
Lennox furnace warranty
Lennox furnace warranties vary depending on the model. All three series have warranties that cover 5 to 10 years on basic parts and a 20-year to lifetime warranty for the heat exchanger. Optional extended parts and labor warranties are available for eligible models from the Merit and Elite series.
