Cost of a New Furnace Guide
The average gas furnace cost typically ranges between $3,800 and $12,000, including the unit and professional installation.1 This price varies significantly based on energy efficiency ratings, home size, and installation complexity. A basic single-stage model sits at the lower end, while a high-efficiency modulating furnace with advanced features represents a premium investment in long-term comfort.
When it comes to heating your home, natural gas furnaces are considered the most popular choice in the United States and Canada. But nailing down a precise price tag requires looking at the variables. According to HomeAdvisor, there is a rather wide range – on average, between $3,800-$12,000, including furnace installation costs.1
On the low end, the actual cost of the furnace might be less than $3,800 but that doesn’t include any installation labor or other material costs. The high end reflects a deluxe, high-efficiency model but in some cases could cost over $12,000 if new venting is required, plus, other materials and gas furnace installation labor.
Of course, average costs don’t really tell the whole story. By itself, a new furnace can be an energy-efficient and cost-effective heating system. When installed along with an air conditioner and evaporator coil, it becomes the central part of a complete HVAC system.

Cost To Replace Furnace and Furnace Price Variables
The cost to replace gas furnace units depends heavily on technology and labor. Pricing differs based on the unit's efficiency (AFUE), heating capacity (BTUs), and advanced comfort features. If you are replacing an existing furnace with a similar unit, installation costs will generally be lower. However, if your new furnace requires additional labor and materials to run new ductwork or venting, the gas furnace cost installed will increase.

Types of Gas Furnaces Impact Pricing
While electric and oil furnaces exist, natural gas models are the most popular choice for their cost-effectiveness. The technology within the furnace significantly dictates the price point:
- Single-stage furnace: This is the most basic and affordable option. It operates at 100% capacity when on and turns off completely when the temperature is reached. While cost-effective upfront, you may experience wider temperature fluctuations.
- Two-stage furnace: A step up in comfort, these models operate at a lower, energy-saving capacity most of the time and kick into high gear only when necessary. This creates more consistent temperatures and better energy efficiency than single-stage models.
- Modulating furnace: The pinnacle of comfort and efficiency. These units adjust their heating output in tiny increments to maintain a precise temperature. While they have a higher initial gas furnace cost, they are often the most energy-efficient options available, offering potential long-term savings.
Energy Efficiency (AFUE)
Efficiency is a major driver of equipment cost. You can check to see how energy efficient a natural gas furnace is by checking its AFUE (Annual Fuel Utilization Efficiency) rating. Think of AFUE like the MPG of your car; a higher number means the unit converts more fuel into usable heat. Learn more about AFUE.
High-efficiency furnaces generally carry a higher price tag due to the advanced components required to capture and recycle heat, but they often pay for themselves over time through reduced utility bills.
Additional New Furnace Costs: Installation Breakdown
When calculating the total gas furnace installation cost, labor and materials play a huge role. Furnace installation requires licensed professionals to handle gas lines, electrical connections, and venting safely.
Here is a breakdown of potential installation variables:
- Labor: Expect typical labor costs to range from $75 - $100 per hour for a licensed technician. A complex install can take 10-15 hours.1
- Permits/inspections: Local regulations vary, but if required, permits can cost between $400 - $1,500.1
- Furnace removal: Disposing of your old unit safely usually costs between $60 - $500.1
- Ductwork: Modifications can range from minor repairs ($2,000 or less) to a full system replacement (up to $5,000).1

How Much Is A New Furnace? Choosing the Right Model
Selecting a furnace isn't just about the lowest sticker price; it's about investing in the right solution for your climate and comfort needs.
- Cold Climate: If you face harsh winters, a high-efficiency, modulating furnace is often the smart financial move. The initial gas furnace cost is higher, but the fuel savings over a long heating season are substantial.
- Warm/Humid Climate: In areas with mild winters, a lower efficiency, single-stage model might suffice. However, if humidity is a concern, pairing a variable-speed furnace with your air conditioner can significantly improve indoor comfort.
- Rebates and Incentives: While high efficiency furnaces cost more upfront, utility rebates can help offset the investment.
Frequently Asked Questions
You should expect to spend between $3,800 and $12,000 on a new furnace, including both the unit and installation costs. Factors influencing the price include the type of furnace (gas, electric, or oil), the unit's efficiency rating, and the complexity of the installation.
Yes, for many homeowners, especially those in colder climates, high-efficiency furnaces are worth the investment. While the upfront gas furnace cost is higher, units with 90%+ AFUE ratings waste less fuel, resulting in lower monthly utility bills that can offset the purchase price over time.
A well-maintained gas furnace should last 15+ years. If your unit is under 15 years old, minor repairs are generally a worthwhile investment. However, if repair costs approach 50% of the value of a new system, or if the unit is older than 15 years, replacement is often the more financially sound choice.
Look for special off-season furnace pricing from local HVAC contractors, consider a higher efficiency model that qualifies for tax credits or utility company rebates, or include a new furnace when replacing an aging air conditioner to save on labor.
Homeowners insurance typically does not cover furnace repairs or replacement due to normal wear and tear. However, it may cover furnace damage caused by unexpected events like fire, vandalism, or certain natural disasters.
