Replacing or installing a new furnace and central air system requires a significant investment. The cost of a new furnace and central air depends on various factors such as equipment type, home size, installation complexity, and geographic location. This guide provides an in-depth analysis of price ranges, factors affecting costs, and tips to budget effectively for your HVAC upgrade.
| Component | Average Cost Range | Key Factors |
|---|---|---|
| Furnace | $1,500 – $6,000 | Type (gas, electric, oil), efficiency rating, size |
| Central Air Conditioner | $2,000 – $7,500 | SEER rating, tonnage, brand, installation complexity |
| Installation | $1,200 – $3,000 | Labor rates, ductwork modifications, system complexity |
| Additional Costs | $500 – $2,000 | Permits, maintenance plans, old unit removal |
Factors Influencing the Cost of New Furnace and Central Air Systems
The total cost of installing a new furnace and central air system varies due to several factors that impact both equipment and labor expenses. Understanding these factors helps homeowners make informed decisions and anticipate budget requirements.
Type of Furnace
Furnaces come in various types such as gas, electric, oil, and propane. Gas furnaces are typically preferred for their efficiency and lower operational costs but tend to have a higher upfront price compared to electric furnaces. Oil furnaces can be more expensive to run due to fluctuating fuel prices.
Efficiency Ratings
Higher-efficiency units with ratings like AFUE (Annual Fuel Utilization Efficiency) or SEER (Seasonal Energy Efficiency Ratio) cost more upfront but offer significant energy savings. Most modern furnaces have AFUE ratings between 80% and 98.5%, while central AC systems typically range from SEER 13 to SEER 25.
Size and Capacity
Choosing the right size furnace and central air unit is critical. Units that are too small won’t adequately heat or cool the home, while oversized units waste energy and reduce comfort. HVAC professionals perform load calculations based on square footage, insulation, and climate zone.
Installation Complexity
Costs increase if ductwork needs repair or replacement, if permits are required, or if installation involves complex configurations. Homes with existing compatible duct systems typically incur lower installation expenses. Geographic location also influences labor rates significantly.
Average Costs for Furnaces
The price of a new furnace can vary depending on several attributes and local market conditions. Below are typical price brackets for different furnace types and efficiency levels.

| Furnace Type | Price Range (Equipment Only) | Typical AFUE Rating |
|---|---|---|
| Gas Furnace | $1,200 – $4,500 | 80% – 98.5% |
| Electric Furnace | $500 – $2,500 | 95% – 98% |
| Oil Furnace | $2,000 – $5,000 | 80% – 90% |
High-efficiency gas furnaces with advanced features like modulating burners and variable-speed blowers are at the top price range but offer lower energy bills.
Average Costs for Central Air Conditioning Systems
Central air conditioning costs can fluctuate based on system size, brand, and efficiency. Most homeowners pay between $2,000 and $7,500 for a complete central AC system, including installation.
| System Size (Tonnage) | Price Range (Equipment Only) | SEER Ratings |
|---|---|---|
| 1.5 – 2 Tons | $1,500 – $3,000 | 13 – 16 SEER |
| 2.5 – 3 Tons | $2,500 – $5,000 | 14 – 18 SEER |
| 3.5 – 5 Tons | $4,000 – $7,500 | 16 – 25 SEER |
Higher SEER ratings provide better energy efficiency but may come at a greater initial cost.
Installation Costs and Additional Expenses
Beyond furnace and AC system prices, installation costs and other fees can add significantly to the total expenditure.
Labor and Installation Charges
On average, installation costs range between $1,200 and $3,000. This includes setting up equipment, electrical wiring, refrigerant charging, and testing system performance. Labor charges vary by region and installer qualifications.
Ductwork Modifications or Repairs
If the existing duct system is in poor condition, repair or replacement might be required. Costs range from $1,000 to $5,000 based on the extent of work. Properly sealed ducts improve HVAC efficiency significantly.
Permits and Inspection Fees
Depending on local regulations, permits may be mandatory. These fees can range from $50 to $500, ensuring that installations meet safety and code requirements.

Removal of Old Equipment
Some contractors include old furnace and AC removal in their services, while others charge extra, typically $100-$500.
Factors That Affect Long-Term Costs and Savings
Choosing the right system affects not only upfront expenses but also ongoing costs like energy bills and maintenance.
Energy Efficiency and Utility Savings
High-efficiency furnaces and central AC units reduce energy consumption, leading to lower monthly heating and cooling bills. Energy Star-certified systems qualify for rebates and incentives, enhancing cost-effectiveness.
Maintenance and Durability
Regular maintenance prolongs system lifespan and maintains efficiency. Budgeting for annual inspections, filter changes, and minor repairs is essential to avoid costly breakdowns.
Warranty and Service Plans
Extended warranties and service agreements can reduce unexpected expenses but increase initial costs. Homeowners should review terms carefully for comprehensive coverage.
Tips for Budgeting and Finding the Best Deals
- Get multiple quotes: Compare estimates from at least 3 licensed HVAC contractors.
- Check efficiency ratings: Balance upfront costs with potential utility savings.
- Ask about rebates: Federal, state, and local incentives may offset expenses.
- Schedule during off-season: HVAC companies often offer discounts in fall or early spring.
- Verify contractor credentials: Confirm licenses, insurance, and customer reviews.
