A new furnace is the backbone of your home's heating system, and choosing the right unit affects both comfort and energy costs for the next 15–20 years. The national average for furnace installation — including equipment, labor, and permits — is approximately $4,500. Gas furnaces remain the most popular choice, but electric furnaces are gaining traction in areas without natural gas service. High-efficiency condensing furnaces (96%+ AFUE) cost more upfront but can save $300–$600 per year in heating costs compared to standard 80% AFUE models.
Gas furnaces are the dominant heating choice in the U.S., accounting for roughly 55% of home heating systems. They cost more to install but are significantly cheaper to operate than electric resistance furnaces in most markets because natural gas is typically 3–4 times less expensive per BTU than electricity. Electric furnaces have lower upfront costs and simpler installation (no gas line, no venting) but higher monthly operating costs. Oil furnaces are common in the Northeast where natural gas is unavailable.
Furnace capacity is measured in BTUs (British Thermal Units) per hour of heat output. The right size depends on your home's square footage, insulation quality, climate zone, and window area. A contractor should perform a Manual J load calculation to determine the correct BTU rating. Common residential sizes range from 40,000 BTU for small homes to 120,000+ BTU for large homes in cold climates.
AFUE (Annual Fuel Utilization Efficiency) measures how much of the fuel a furnace converts into heat. An 80% AFUE furnace sends 20% of its energy up the exhaust flue, while a 96% AFUE model loses only 4%. High-efficiency condensing furnaces (90%+ AFUE) extract additional heat from exhaust gases by using a secondary heat exchanger. They require PVC venting instead of traditional metal flue pipes, which simplifies installation in many homes. The DOE minimum is 80% AFUE in the South and 90% AFUE in the North as of 2023.
Furnace brands are generally grouped into three quality and price tiers. Budget brands offer solid reliability at the lowest cost. Mid-range brands add features like variable-speed blowers and quieter operation. Premium brands offer modulating gas valves, the highest efficiency ratings, and the longest warranties. All major brands are manufactured by just a few parent companies — Carrier, Lennox, Trane, and Rheem — so quality differences within a tier are often minimal.

Labor accounts for roughly 40–50% of a furnace replacement project. A straightforward swap — same fuel type, same location, compatible ductwork — typically takes 4–8 hours for a crew of 2 technicians. Installing a high-efficiency condensing furnace in a home that previously had an 80% AFUE unit requires new PVC venting, a condensate drain line, and sometimes electrical upgrades, which can add a full day of work. Converting from oil to gas requires a new gas line ($500–$2,000) and removal of the old oil tank ($500–$1,500).
A standard furnace replacement takes 4–8 hours. Fuel conversions or complex installations may take 1–2 days.
Gas furnaces typically last 15–20 years with regular maintenance. Electric furnaces can last 20–30 years since they have fewer mechanical components. Signs it's time to replace include frequent repairs, rising energy bills, uneven heating, and a cracked heat exchanger (a safety hazard).
In most cases, yes. A 96% AFUE furnace costs $1,500–$3,000 more than an 80% model but saves $300–$600 per year on gas bills. The payback period is typically 4–7 years, after which you save money for the remaining 10–15 years of the unit's life. The savings are even greater in cold climates with long heating seasons.
No. Furnace installation requires working with gas lines, high-voltage electrical connections, and combustion venting — all of which require licensed professionals and permits. Improper installation creates serious carbon monoxide and fire risks. Most jurisdictions require permits and inspections for furnace installations.
If natural gas is available in your area, switching from oil to gas typically saves 25–40% on heating costs and eliminates the need for oil deliveries and tank maintenance. The conversion costs $3,000–$7,000 (including new gas line and oil tank removal) but pays for itself in 3–5 years through lower fuel costs.
