Most Missouri homeowners can expect a furnace replacement cost between $4,000 and $9,500 fully installed in 2026, with the typical mid-efficiency gas furnace replacement falling around $5,500 to $8,000 for a 1,500 to 2,000 square foot home.

Missouri Furnace Replacement Cost Overview for 2026

Knowing the local averages before you request quotes gives you a solid frame for evaluating whether an estimate is fair.

Average Furnace Replacement Cost in Missouri

Missouri furnace replacement cost ranges from $4,000 to $9,500 fully installed in 2026, depending on fuel type, efficiency rating, size, and installation complexity. Standard 80 percent AFUE gas furnaces run $4,000 to $6,500 installed in the Missouri market. Mid-efficiency 90 to 92 percent AFUE condensing furnaces run $5,500 to $8,000. High-efficiency 95 to 98 percent AFUE furnaces run $6,500 to $9,500. Electric furnaces run $4,000 to $7,000 installed, and oil furnaces (rare in Missouri) run $5,000 to $9,000.

What Monett Homeowners Should Know

Homeowners in Monett and surrounding areas typically deal with Ozark winter cold snaps that push temperatures into the teens or single digits, which makes furnace efficiency and reliability especially valuable. Southwest Missouri labor rates typically run 5 to 10 percent below Kansas City and St. Louis, so local quotes often come in a few hundred dollars under statewide averages. Reputable installers perform a Manual J load calculation to correctly size the equipment for your specific home and provide a written itemized estimate before starting work.

• Ozark cold snaps: Winter lows in the teens or single digits demand reliable heating.
• Regional labor rates: Southwest Missouri typically 5-10% below metro Missouri.
• Written estimates: Reputable contractors itemize equipment, labor, and materials.
• Manual J sizing: Prevents oversizing that wastes energy and shortens equipment life.

5 Factors That Determine Furnace Replacement Cost

The following five factors account for nearly every dollar difference between furnace replacement quotes in the Missouri market. Understanding each one helps you compare estimates fairly and pick the right equipment for your home.

1. Furnace Type and Fuel Source

Furnace type is the single biggest factor in replacement cost because gas, electric, and oil furnaces have very different equipment costs, installation requirements, and operating expenses. Natural gas furnaces are the most common in Missouri and typically run $4,000 to $9,500 installed, with pricing scaling with efficiency. Propane furnaces are common in rural Missouri homes without natural gas service and cost about the same as gas equipment but usually more to operate. Electric furnaces cost $4,000 to $7,000 installed but often cost more to operate because electricity is more expensive per BTU than natural gas in Missouri. Oil furnaces are rare in the region and typically cost $5,000 to $9,000 installed plus higher fuel storage and delivery expenses.

• Natural gas: Most common in Missouri suburbs and cities.
• Propane: Standard for rural Missouri homes without gas lines.
• Electric: Lower upfront cost but higher operating expense.
• Oil: Uncommon in the region, more expensive to operate.

2. AFUE Efficiency Rating and Federal Tax Credits

AFUE rating measures how much fuel energy your furnace converts to usable heat, and higher AFUE means lower monthly bills but higher upfront cost. Standard 80 percent AFUE furnaces cost the least at $4,000 to $6,500 installed in Missouri, while mid-range 90 to 92 percent AFUE condensing furnaces run $5,500 to $8,000, and premium 96 to 98 percent AFUE units with variable-speed blowers reach $6,500 to $9,500. According to ENERGY STAR, certified gas furnaces in the northern half of the U.S., which includes Missouri, are up to 18 percent more energy efficient than baseline models and can save $160 a year in energy costs. Higher-efficiency furnaces qualify for a federal tax credit of up to $600 when they meet the 97 percent AFUE threshold, and Missouri utilities like Ameren and Evergy commonly offer rebates of $200 to $1,000 on qualifying installations.

• 80% AFUE: Lowest cost, appropriate for mild climates or short home tenure.
• 90 to 92% AFUE: Best value for most Missouri homes with 5 to 10 year payback.
• 96 to 98% AFUE: Premium efficiency, best for long-term homeowners in cold climates.
• Incentives: Up to $600 federal tax credit plus $200 to $1,000 in Missouri utility rebates.

3. Furnace Size and BTU Capacity

Furnace sizing directly affects replacement cost because larger units require more materials, larger heat exchangers, and stronger blowers. Residential furnaces are sized in BTUs with common capacities from 40,000 BTU for small homes up to 120,000 BTU for large ones. In the Missouri market, a 40,000 to 60,000 BTU furnace installed runs $4,000 to $6,500, a 60,000 to 80,000 BTU unit runs $5,000 to $8,000, an 80,000 to 100,000 BTU unit runs $6,000 to $9,000, and 100,000-plus BTU units reach $7,000 to $9,500. Proper sizing through a Manual J load calculation prevents oversizing that wastes energy and undersizing that fails to keep the home warm during Missouri cold snaps.

• 40 to 60 kBTU: Fits smaller Missouri homes around 1,000 to 1,500 square feet.
• 60 to 80 kBTU: Common for 1,500 to 2,200 square foot homes.
• 80 to 100 kBTU: Typical for 2,200 to 3,000 square foot homes.
• 100 kBTU-plus: Larger homes or poorly insulated older properties.

4. Brand, Features, and Optional Add-Ons

Brand and feature selection can swing a furnace replacement quote by $1,500 to $3,500 for the same capacity and AFUE rating. Value brands like Goodman, Payne, and Rheem sit at the lower end of Missouri pricing with reliable equipment and standard warranties, while premium brands like Carrier, Trane, Lennox, and Rudd command 15 to 25 percent higher prices for enhanced warranties, quieter operation, and advanced features. Feature options that raise price include variable-speed ECM blowers, two-stage or modulating gas valves, and Wi-Fi thermostat compatibility. Popular optional add-ons at installation include whole-home humidifiers ($400 to $900 installed for the dry Missouri winter), electronic air cleaners ($600 to $1,500), UV coil lights ($300 to $700), and smart thermostats ($200 to $500).

• Value brands: Reliable equipment at lower cost with standard warranties.
• Premium brands: Enhanced warranties and refined features at higher cost.
• Comfort features: Variable-speed blowers and two-stage burners improve daily use.
• Add-ons: Humidifiers and air cleaners handle Missouri’s dry winter and dusty summer air.

5. Installation Complexity, Labor, and Permits

Installation complexity often surprises Missouri homeowners because two identical furnaces can have very different install prices depending on the home. A straightforward like-for-like replacement in an accessible basement runs $800 to $1,500 in labor in the Monett and surrounding areas market. Upgrading from an 80 percent unit to a 90 percent-plus condensing furnace adds $500 to $1,500 for new PVC venting and condensate drainage. Attic or crawlspace installations add $300 to $800 for access and platform work. Ductwork modifications, gas line resizing, electrical upgrades, and asbestos abatement on older Missouri homes can each add another $500 to $3,000 to the total. Permits typically run $50 to $250 in most Missouri jurisdictions and are usually pulled by the contractor as part of the install.

• Straightforward swap: Basement replacement of like-for-like equipment.
• Venting upgrades: Condensing furnaces require new PVC vent piping.
• Ductwork changes: Undersized returns often require sheet metal work.
• Permits: $50 to $250 in most Missouri jurisdictions.
