When Ohio temperatures dip below freezing, few questions feel more urgent than “how much does it cost to replace furnace equipment in my home?” CountBricks answers that question every day through our AI-driven estimate platform, combining real-time material pricing, local labor rates, and instant blueprint takeoffs. Below, we break down current cost ranges, explain the variables that move the numbers up or down, and show how CountBricks keeps residential construction budgets predictable.
Based on thousands of CountBricks residential estimates generated over the past 12 months, a complete furnace replacement typically runs between $4,600 and $10,200 for a 1,800 ft² single-family home. The broad range reflects equipment choice, installation complexity, and regional code requirements.
• System capacity: A 40,000 BTU gas unit costs far less than a 120,000 BTU high-output model.
• Efficiency rating: 80% AFUE furnaces remain legal in some jurisdictions, but 95%+ condensing models add 15-30% to equipment cost.
• Fuel source: Gas remains most common, yet electric and oil furnaces have different price curves and electrical or tank considerations.
• Ductwork condition: Swapping the box is simple; resizing or sealing ducts can add $1,200-$3,500.
• Code & permit fees: Municipal inspections, venting upgrades, and fresh-air intakes vary by county.
• Labor market: Seasonal demand and skilled-labor shortages shift hourly rates by as much as 20% within a single metro.
1. Standard 80% AFUE gas furnace: $1,100-$1,900
2. High-efficiency 96% AFUE condensing furnace: $2,000-$3,600
3. Variable-speed blower upgrade: $350-$600
• Sheet-metal plenums, transition collars, and dampers: $180-$450
• PVC venting for condensing units: $120-$400
• Gas line modifications, shut-off valve, drip leg: $90-$250
• Electrical whip, disconnect, thermostat wire: $75-$160
• Removal of existing furnace: 2-3 hours @ $70-$100/hr
• Placement, leveling, and tying into supply/return: 4-6 hours @ $70-$100/hr
• Commissioning, combustion analysis, homeowner orientation: 1-2 hours @ $70-$100/hr

The Smiths owned a 1990s 2,400 ft² colonial. Their 80% furnace failed mid-January. Using CountBricks, the contractor captured the scope in 12 minutes, emailed a $7,850 fixed-price quote, and replaced the unit within 48 hours. The project closed at $7,850—no change orders, no surprises, 15% faster than the regional average.
