Furnace Replacement Cost Estimator by Fuel Type
Get an accurate furnace replacement cost estimate by fuel type — gas, electric, or propane — with current 2026 Florida pricing delivered in 24–48 hours.
What This Furnace Replacement Estimate Covers
A furnace is heating-only equipment, distinct from a full air conditioning or heat pump system, and pricing depends heavily on fuel type: gas, electric, or propane. This estimator prices furnace replacement specifically by fuel type, distinct from our HVAC replacement cost estimator, which covers whole-system replacement (central air, heat pumps, ductwork) rather than furnace/heating equipment alone.
Electric furnaces are the most common heating equipment in Florida's climate and run $1,500-$6,500 installed, roughly 40% cheaper upfront than gas furnaces. Gas furnaces, less common in Florida but still found in some homes and new construction, run $2,500-$11,200 installed, with most homeowners spending $4,500-$6,300. Every electric furnace runs at 100% AFUE efficiency since all electricity converts directly to heat, while gas furnace efficiency varies by model, with high-efficiency 96%+ AFUE units adding about 30% to the upfront price.
If you need whole-system HVAC pricing including cooling rather than heating-only equipment, see our HVAC replacement cost estimator. For commercial HVAC installation, see our commercial HVAC installation cost estimator.
Upfront Cost vs. Operating Cost: The Real Tradeoff
Electric furnaces cost less upfront but typically run higher annual operating costs ($900-$2,000 per year) than gas furnaces ($500-$1,200 per year), since electricity costs more per BTU than natural gas in most markets. In Florida, where furnace-only heating runs far fewer hours per year than in colder states, the lower upfront cost of electric furnaces often makes more financial sense over the equipment's life than it would in a cold-climate state.
Electric Furnace
Most common in Florida, $1,500-$6,500 installed, 100% AFUE efficiency.
Gas Furnace
Higher upfront cost at $2,500-$11,200, lower annual operating cost.
Propane Furnace
Alternative for homes without natural gas service, priced similarly to gas.
High-Efficiency Upgrade
96%+ AFUE units add ~30% to price but reduce annual heating costs.

What Affects Furnace Replacement Cost in Florida
Fuel Type
Electric, gas, and propane furnaces carry meaningfully different upfront and operating costs.
Efficiency Rating (AFUE)
Higher-efficiency furnaces cost more upfront but reduce annual heating costs, a smaller factor in Florida's mild climate than in cold states.
Furnace Size (BTU)
Properly sized equipment for your home's square footage affects both cost and heating performance.
Existing Ductwork Condition
Furnace replacement paired with ductwork repair or replacement adds cost beyond the unit itself.
Gas Line Availability
Homes without existing gas service face added cost to run a gas line for a gas furnace conversion.
Permits
Furnace replacement in Florida typically requires a mechanical permit and inspection.
Region
South Florida labor rates typically run higher than North or Central Florida for comparable furnace installation.
Combined System Replacement
Replacing a furnace alongside AC or heat pump equipment may reduce combined labor cost versus separate projects.

Frequently Asked Questions
This estimator prices furnace (heating-only equipment) replacement by fuel type — electric, gas, or propane — distinct from whole-system HVAC replacement covering both heating and cooling.
Electric furnaces run $1,500-$6,500 installed, while gas furnaces run $2,500-$11,200, with most homeowners spending $4,500-$6,300 on a gas furnace replacement.
Electric furnaces cost less upfront (roughly 40% cheaper), though gas furnaces typically have lower annual operating costs; Florida's mild climate reduces how much annual operating cost matters overall.
Electric furnaces typically last 20-30 years, while gas furnaces last 15-25 years.
If you only need heating equipment replaced and your air conditioning is separate and functioning, furnace-only replacement may be sufficient; for full system replacement, see our HVAC replacement cost estimator.
Yes, see our commercial HVAC installation cost estimator for commercial-scale pricing.
