Furnace replacement means replacing only the heating unit, not the entire HVAC system. It works with your existing air conditioning system.
It typically includes:
This is different from HVAC replacement (full system) or heat pump replacement. Furnace replacement is for heating only and works with your existing AC or cooling system.
Nationally, furnace replacement costs vary significantly depending on:
Gas, electric, or oil furnaces
80% to 98%+ efficiency options
BTU capacity needed
Vent work, duct modifications
That's why state-level and city-level pricing is the most accurate way to estimate your real furnace replacement cost.

(gas typically cheaper than electric upfront)
(80-90% standard, 90-98%+ high-efficiency)
(40,000-150,000+ BTUs typical)
(existing vs new vent work needed)
(if modifications or repairs needed)
(varies by state and city)
Each state page breaks these factors down with local context and typical price ranges.
→ Heating unit only (works with existing AC)
→ Full system (furnace + AC together)
→ All-in-one system (heating + cooling in one unit)
→ Cooling unit only (works with existing furnace)
If your AC is still working well, furnace-only replacement is often the most cost-effective option.
If both your furnace and AC are aging, consider full HVAC replacement for better efficiency and system compatibility.

Gas furnaces typically cost less to operate in most areas and heat faster, but require gas line access. Electric furnaces are easier to install and maintain but cost more to run. Your contractor can recommend the best option based on your home and local utility rates.
Standard efficiency (80-90% AFUE) works well for most homes. High-efficiency (90-98%+ AFUE) costs more upfront but saves significantly on heating bills, especially in cold climates. The higher the AFUE, the more heat you get from each unit of fuel.
Yes, but if your AC is also aging (10+ years), replacing both together (full HVAC replacement) is often more cost-effective and ensures better system compatibility and efficiency.
