Key factors that impact furnace replacement cost

Fuel type

(gas typically cheaper than electric upfront)

AFUE rating

(80-90% standard, 90-98%+ high-efficiency)

Home size & BTU capacity

(40,000-150,000+ BTUs typical)

Ventilation system

(existing vs new vent work needed)

Ductwork condition

(if modifications or repairs needed)

Local permits & labor

(varies by state and city)

Each state page breaks these factors down with local context and typical price ranges.

Furnace replacement vs other system replacements

Furnace replacement

→ Heating unit only (works with existing AC)

HVAC replacement

→ Full system (furnace + AC together)

Heat pump replacement

→ All-in-one system (heating + cooling in one unit)

AC replacement

→ 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.

Furnace replacement cost FAQs

How much does furnace replacement cost in my state?

Furnace replacement costs vary by state due to labor rates, fuel availability, and local regulations. Use your state page for accurate ranges based on home size, fuel type, and efficiency needs.

Should I choose a gas or electric furnace?

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.

What AFUE rating should I choose?

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.

Can I replace just the furnace if my AC is old?

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.
